Foreword
Conventional agriculture has largely been characterized by tillage, which leaves
soil vulnerable to erosion. Continuous use of conventional farming practices with
conventional tillage and burning crop residues has degraded the soil resource base
and intensified soil degradation, with concomitant decreases in crop production ca-
pacity. Soil loss is expected to be a critical issue for global agricultural production
under conventional farming practices. For instance, global erosion rates from con-
ventionally ploughed agricultural fields averaged one to two orders of magnitude
greater than erosion under native vegetation, long-term geological erosion and rates
of soil production. Likewise, conventional tillage has also made agriculture a major
contributor to global warming due to increasing greenhouse gas emissions. Soil and
vegetation on the earth’s land surface store three times as much carbon as is present
in the earth’s atmosphere. Land clearing and degradation turn this valuable carbon
sink into a major source of greenhouse gas emissions.
Conservation agriculture is widely recognized as a viable approach to creating
a sustainable agriculture. It is a resource-saving agricultural production system
that aims to achieve production intensification and high yields while enhancing
the natural resource base through compliance with four interrelated principles viz.
minimal soil disturbance, permanent residue cover, planned crop rotations and in-
tegrated weed management, along with other good production practices of plant
nutrition and pest management.
Conservation agriculture is environment friendly and requires less fuel, result-
ing in lower emissions of carbon dioxide—one of the gases responsible for global
warming. In addition, conservation agriculture is very effective in reducing soil
erosion. A wide range of other environmental benefits accrue in conservation agri-
culture, including reduced run-off, improved nutrient cycling, reduced soil degrada-
tion, reduced soil and water pollution and enhanced activities of soil biota.
Although several papers and conference proceedings are available on the sub-
ject, a comprehensive textbook on conservation agriculture was lacking. This book
is a timely effort to fill the gap. The book describes various elements of conserva-
tion agriculture, highlights the associated breeding and modeling efforts, analyses
the experiences and challenges in conservation agriculture in different regions and
proposes some pragmatic options and new areas of research in this very important
area of agriculture.

Preface
The conventional mode of agriculture through intensive agricultural practices
achieves production goals, but simultaneously degrades the natural resources. The
growing concerns for sustainable agriculture are in response to the limitations of
both low-input, traditional agriculture and intensive modern agriculture relying on
high levels of inputs for crop production. Sustainable agriculture relies on practices
that help to maintain ecological equilibrium and encourage natural regenerative
processes such as nitrogen fixation, nutrient cycling, soil regeneration, and the pro-
tection of natural enemies of pest and diseases as well as the targeted use of inputs.
Agricultural systems relying on such approaches not only support high productivity,
but also preserve biodiversity and safeguard the environment. Conservation agri-
culture is a new paradigm for achieving sustained agricultural production and is a
major step in the transition to sustainable agriculture.
Over the past few decades, resource conservation technologies, such as zero
and reduced-tillage systems, better crop residue management and planting systems,
have evolved to enhance water and nutrient conservation. Conservation agricul-
ture—an array of four components including permanent soil cover, minimum soil
disturbance, diversified crop rotations and integrated weed management—is now
considered the principal road to sustainable agriculture and the protection of natural
resources and the environment. Currently, conservation agriculture is practiced on
more than 125 million ha worldwide.
While the adoption of conservation agriculture is increasing globally, in some
regions it is either slow or non-existent. As a result, we felt it timely to collect and
synthesize the latest developments on conservation agriculture research. The con-
tents of this book are divided into five sections and 23 chapters as detailed below:
(1) Introduction
Chapter 1 is a brief history and overview of the components and adaptation of
conservation agriculture.
(2) Elements of conservation agriculture
• Chapter 2 collates and performs a meta-analysis on existing literature on the
effect of crop rotations and crop residue management on maize grain yield
under conservation agriculture.
viii Preface
• Chapter 3 describes weed problem in conservation agriculture systems and
proposes the strategies for integrated weed management.
• Chapter 4 discusses the nutrient management perspectives in conservation
agriculture, and suggests the strategies for improving the nutrient use effi-
ciency in conservation agriculture systems.
• Chapter 5 is an overview of the essential machinery requirements for the
different farm operations involved in conservation agriculture. Regional-
specific issues with emphasis on developing countries are also discussed,
and pragmatic solutions of vital interest to researchers, academia and policy
makers globally are proposed.
• Chapter 6 describes the impact of conservation agriculture on the preva-
lence of insects, insect biodiversity, and proposes options for integrated
insect pest management in conservation agriculture.
(3) Modeling and crop improvement for conservation agriculture
• Chapter 7 covers crop breeding for conservation agriculture. Crop improve-
ment and breeding strategies are proposed to develop improved crop geno-
types better adapted to conservation agriculture.
• Chapter 8 introduces the SALUS model and its tillage component to evalu-
ate the effects of tillage on soil water infiltration, time to ponding and soil
biophysical properties.

• Chapter 11 describes the experiences, challenges and options regarding con-
servation agriculture in South Asia.
• Chapter 12 covers conservation agriculture in South East Asia and intro-
duces the Conservation Agriculture Network for South East Asia.
• Chapter 13 discusses conservation agriculture in China, particularly in rain-
fed areas, including early history and progress on research and adoption for
better soil and water conservation.
• Chapter 14 discusses the future of conservation farming in Australia and
New Zealand, and recent advances in weed control strategies.
• Chapter 15 outlines future prospects for up-scaling of conservation agri-
culture in Europe, and describes the likely impact of global changes and

Abstract Conservation agriculture (CA) is characterized by minimal soil distur-
bance, diversified crop rotations, and surface crop residue retention to reduce soil
and environmental degradation while sustaining crop production. CA involves
changing many conventional farming practices as well as the mindset of farmers
to overcome the conventional use of tillage operations. Although adoption of CA is
increasing globally, in some regions it is either slow or nonexistent. The adoption of
CA has both agricultural and environmental benefits but there is a lack of informa-
tion on the effects and interactions of key CA components which affect yield and
hinder its adoption. In this chapter, we discuss the basic concepts and brief history
of CA, and its impacts on agricultural systems.

1.1 Introduction
Conventional farming practices, in particular tillage and crop residue burning, have
substantially degraded the soil resource base (Montgomery 2007; Farooq et al.
2011a), with a concomitant reduction in crop production capacity (World Resources
Institute 2000). Under conventional farming practices, continued loss of soil is ex-
pected to become critical for global agricultural production (Farooq et al. 2011a).
4 M. Farooq and K. H. M. Siddique
Conservation agriculture (CA) is a set of technologies, including minimum soil
disturbance, permanent soil cover, diversified crop rotations, and integrated weed
management (Fig. 1.1; Reicosky and Saxton 2007; Hobbs et al. 2008; Friedrich
et al. 2012), aimed at reducing and/or reverting many negative effects of conven-
tional farming practices such as soil erosion (Putte et al. 2010), soil organic mat-
ter (SOM) decline, water loss, soil physical degradation, and fuel use (Baker et al.
2002; FAO 2008). For instance, soil erosion, water losses from runoff, and soil
physical degradation may be minimized by reducing soil disturbance and maintain-
ing soil cover (Serraj and Siddique 2012). Using organic materials as soil cover and
including legumes in rotations may help to address the decline in SOM and fertility
(Marongwe et al. 2011). With less soil disturbance comes less fuel use, resulting in
lower carbon dioxide emissions, one of the gases responsible for global warming
(Kern and Johnson 1993; West and Marland 2002; Hobbs and Gupta 2004; Holland
2004; Govaerts et al. 2009). CA helps to improve biodiversity in the natural and
agro-ecosystems (Friedrich et al. 2012). Complemented by other good agricultural
practices, including the use of quality seeds and integrated pest, nutrient and water
management, etc., CA provides a base for sustainable agricultural production inten-
sification (Friedrich et al. 2012). Moreover, yield levels in CA systems are compa-
rable and even higher than traditional intensive tillage systems (Farooq et al. 2011a;
Friedrich et al. 2012) with substantially less production costs (Table 1.1).
CA is increasingly promoted as “a concept of crop production to a high and
sustained production level to achieve acceptable profit, while saving the resources
along with conserving the environment” (FAO 2006). In CA, modern and scientific
agricultural technologies are applied to improve crop production by mitigating re-
ductions in soil fertility, topsoil erosion and runoff; and improving moisture con-
servation and environmental footprints (Dumanski et al. 2006). CA improves soil

water-use efficiency, enhances water infiltration, and increases insurance against
drought (Colmenero et al. 2013). CA is thus an eco-friendly and sustainable man-
agement system for crop production (Hobbs et al. 2008; Govaerts et al. 2009) with
potential for all agroecological systems and farm sizes. This chapter provides a brief
history and overview of the components and adaptation of CA.
1.2 
History and Adoption of Conservation Agriculture
Tillage is defined as the mechanical manipulation of soil. Tillage started millions
of years ago when man shifted from hunting to more sedentary and conventional
agriculture especially in the Euphrates, Nile, Tigris, Yangste, and Indus valley (Hil-
lel 1991). The idea to plough or till the soil began in Mesopotamia around 3000 BC
(Hillel 1998). Lal (2001) identified tillage as a major component of husbandry prac-
tices in agriculture. After the industrial revolution in the nineteenth century, agricul-
tural machinery became available to carry tillage operations. More recently, a range
of equipment has become available for tillage operations in agricultural production
(Hobbs et al. 2008). Traditionally, tillage was aimed to soften the soil, prepare the
seedbed to ensure good and uniform seed germination, manage weeds, help in the
release of soil nutrients needed for crop growth through mineralization and oxi-
dation, and incorporate crop residues and soil amendments (fertilizers, organic or
inorganic) into the soil (Hobbs et al. 2008). Moreover, tillage helps to modify soil’s
physical, chemical, and biological properties, which improves conditions for crop
growth resulting in higher crop yields (Farooq et al. 2011a).
Tillage, particularly in fragile ecosystems, was questioned for the first time in the
1930s by Edward H. Faulkner, in a manuscript called “Plowman’s Folly” (Faulkner
1943) when dust bowls devastated wide areas of the Midwestern USA (Friedrich
et al. 2012). With time, the concept of protecting soil, by reducing tillage and keep-
ing the soil covered, gained popularity. This system of soil protection was then
named conservation tillage (Friedrich et al. 2012). Economic and ecological suf-
ferings caused by disastrous droughts in the USA during the 1930s drove the shift
towards CA (Haggblade and Tembo 2003). The development of seeding machinery
during the 1940s made sowing possible without soil tillage (Friedrich et al. 2012).
Moreover, increased fuel prices during the 1970s attracted farmers to shift towards
resource-saving farming systems (Haggblade and Tembo 2003). In this scenario,
commercial farmers adapted CA to combat drought-induced soil erosion together
with the fuel saving (Haggblade and Tembo 2003).

During the early 1970s, no-tillage farming reached Brazil; and no-tillage and
mulching were tested in West Africa (Table 1.2; Greenland 1975; Lal 1976). The
CA experience in the USA helped motivate the CA movement in South Africa and
South America (Haggblade and Tembo 2003). Nonetheless, CA took more than 20
years to reach significant adoption levels in South America (Friedrich et al. 2012).
During this time, farm equipment and agronomic practices in no-tillage systems
were improved and developed to optimize crop performance and machinery, and
field operations (Friedrich et al. 2012).
In the early 1990s, the spread of CA hastened, which revolutionized farming
systems in Argentina, southern Brazil, and Paraguay (Friedrich et al. 2012). During
this time, several international organizations became interested in the promotion
of CA. Participation of these organizations in the promotion of these conservation
farming systems led to the adoption of these systems in Africa (Tanzania, Zambia,
and Kenya) and some parts of Asia (Kazakhstan, China, India, and Pakistan). CA
systems then made their way to Canada, Australia, Spain, and Finland.
Today, CA is practiced on millions of hectares across the globe (FAO 2011a)
including the USA, Argentina, Bolivia, Brazil, Chile, China, Colombia, Falkland
Islands, Finland, Kazakhstan, Kenya, Malvinas, Morocco, Uganda, Western Aus-
tralia, and Zambia (Friedrich et al. 2012) on soils varying from 90% sand (e.g.,
Australia) to 80% clay (e.g., Brazil’s Oxisols and Alfisols). Derpsch and Friedrich
(2009) reported that any crop can be grown effectively under CA including tuber
and root crops. In recent years, the spread of CA has been quite rapid. In 1973–
1974, CA was practiced on 2.8 M ha globally, increasing to 6.2 M ha in a decade;
by 1996–1997, this area had reached 38 M ha, and by 2003, it was 72 M ha. More
recently, CA has been practiced on 125 M ha (Friedrich et al. 2012).
CA has positive effects in terms of yield, income, sustainability of land use,
ease of farming, and the timeliness of ecosystem services and cropping practices.
As a result, its adoption rate has increased by 7 M ha per year in the past decade
(Friedrich et al. 2012). Of the total area under CA systems worldwide, 45% is in
South America, 32% in USA and Canada, 14% in Australia and New Zealand, and
9% in the rest of the world including Asia, Europe, and Africa (Table 1.3; Friedrich
et al. 2012). In Canada, CA adoption has seen a pragmatic eco-friendly approach
as that helped to decrease the dust storms and increase the biodiversity (Lindwall
and Sonntag 2010). Carbon payment schemes have been introduced in Alberta and
Canada, which have resulted in the rapid uptake of CA in these areas (Friedrich
et al. 2012).
Despite the continued effort of international organizations and local NGOs, the
total area under CA is only 9% of the total cropped area (Friedrich et al. 2012). A
lack of CAextension programs is one reason for its slow uptake. In addition, region-
al traditions and mindset, along with a lack of technical knowledge, institutional
support, CA machinery, and suitable herbicides to facilitate weed management are
major constraints in the wide-scale adoption of CA systems (FAO 2008; Friedrich
and Kassam 2009; Friedrich et al. 2012). Certain other issues related to natural
assets of the farm also hinder CA adoption worldwide (Dixon et al. 2001; Gov-
aerts et al. 2009). However, in Asia, many agricultural lands may adopt CA systems

especially in Kazakhstan, China, and India in the next two decades (Friedrich et al.
2012). In the Indo-Gangetic Plains (Pakistan, India, Bangladesh, and Nepal), no-
tilled wheat plantations have reached 5 M ha in recent years especially in the rice–
wheat cropping system (Friedrich et al. 2012) and are expected to expand further.
In a nutshell, since the 1930s, farming communities have gradually shifted to-
wards no-tillage systems for potential fossil-fuel savings, reduced erosion, and run-
off, and to minimize SOM loss. The first 50 years was the start of the conservation
tillage movement and, today, a large percentage of agricultural land is cropped fol-
lowing CA principles (Hobbs et al. 2008). Sustained governmental policies and
institutional support may play a key role in the promotion of CA both in rainfed and
irrigated cropped lands by providing incentives and required services to farmers to
adopt CA practices and advance them over time (FAO 2008; Friedrich and Kassam
2009; Friedrich et al. 2009; Kassam et al. 2009, 2010; Friedrich et al. 2012).
1.3 
Permanent or Semi-permanent Organic Soil Cover
In CA, crop residues—the principal element of permanent soil cover—must not
be removed from the soil surface or burned. The residue is left on the soil surface
to protect the topsoil enriched with organic matter from erosion. At the same time,
fresh residues must be added to the soil when existing residues decompose. Burning

not only increases mineralization rates which rapidly depletes nutrients and organic
matter from the soil but also causes air pollution (Magdoff and Harold 2000). In CA,
plants are either left in the field or killed, with their residues left in the field to de-
compose in situ. This practice is primarily aimed at protecting the enriched topsoil
against chemical and physical weathering. Plant residues slow down the speed of
falling raindrops, provide a barrier against strong winds and temperature, decrease
surface evaporation, and improve water infiltration (Thierfelder and Wall 2009).
Cover crops/green manure crops are grown to increase or maintain soil fertility
and productivity. They increase SOM content either by adding fresh plant residues
to the soil or by reducing soil erosion. Legume cover crops can fix nitrogen from
the atmosphere into the soil increasing N availability to crop plants. Cover crops are
mowed or killed before or during soil preparation for the next economic crop. A gap
of 1 or 2 weeks before planting the next crop is needed to allow some decomposi-
tion and reduction in allelopathic effects of the residues, and to minimize nitrogen
immobilization (Miguel et al. 2011; Farooq and Nawaz 2014).
CA improves soil biodiversity, soil biological activity, water quality and soil
aggregation, and increases soil carbon sequestration through maintenance of crop
residues. By keeping residues on the surface and using cover crops, permanent soil
cover is maintained during fallow periods as well as during crop growth phases.
Giller et al. (2009) opined that the benefits of each principle need to be properly
evaluated as trade-offs exist and some farmers have not adopted all of CA compo-
nents. Retaining crop residues has positive and negative effects; researchers should
develop strategies to enhance the positive effects (Kumar and Goh 2000).
1.4 
Minimal Soil Disturbance
CA promotes minimal soil disturbance through no- or reduced tillage, careful man-
agement of residues and organic wastes, and a balanced use of chemical inputs;
all aimed at decreasing soil erosion, water pollution and long-term dependence on
external inputs, improving water quality and water-use efficiency, and minimiz-
ing greenhouse gas emissions by reducing the use of fossil fuels (Kumar and Goh
2000). Zero-tillage systems need minimal mechanical soil disturbance and perma-
nent soil cover to achieve sufficient living and/or residual biomass to control soil
erosion which ultimately improves water and soil conservation (Li et al. 2007).
CA emphasizes the importance of soil as a living body, particularly the most active
zone in the top 0–20 cm, to sustain the quality of life on this planet; yet this zone
is most vulnerable to degradation and erosion. Most environmental functions and
services—essential to support terrestrial life on this planet—are concentrated in the
macro-, micro-, and meso-flora and fauna, which live and interact in this zone. Hu-
man activities with regard to land management have the most immediate and poten-
tially maximum impact in this zone (Hobbs et al. 2008). By protecting this fragile
zone, the vitality, health, and sustainability of life on this planet may be ensured.

A recent modeling analysis, for three sites with fine-textured soils and different
crop rotations in North America (Conant et al. 2007), simulated zero tillage until
equilibrium was reached and ran experimental models for 220 years thereafter. The
model demonstrated a substantial decrease (~27%) in soil C content due to a shift
to conventional tillage from zero tillage (Conant et al. 2007).
1.5 
Diversified Crop Rotations
Crop rotations play a critical role in determining the success of crop production en-
terprises, but are most important in determining the success of crop production sys-
tems using conservation tillage. CA addresses the problems of insect, pests, and dis-
eases by integrating crop rotations, which help break the cycle that perpetuates crop
diseases such as wheat rust and pest infestations (Witmer et al. 2003), resulting in
higher yield. A well-planned systematic crop rotation helps farmers to avoid many
problems linked with conservation tillage, such as increased soil compaction, plant
diseases, perennial weeds, and slow early season growth (Tarkalson et al. 2006).
Continuous maize planting in a no-till system may cause several problems such
as perennial weeds, leaf diseases, inoculum buildup in residues, and wetter and
cooler soils at planting due to heavy maize residues (Fischer et al. 2002). These resi-
dues interfere with seed placement resulting in uneven stand establishment; while
allelopathic effects from decomposing maize residues on young plants may slow
the growth of maize early in the season (Fischer et al. 2002). In such situations, a
maize–hay rotation—as an alternative to continuous maize—is gaining popularity
on dairy farms in Pennsylvania. Many problems linked to continuous no-till maize
may be eliminated in this rotation when the sod is killed in autumn. The residue
level will be manageable, the flux of perennial weeds will be less, insect problems
will be less, and the soil structure usually will be excellent resulting in higher yields.
Inclusion of Sesbania in direct-seeded rice as a green manure intercrop and then
knocking it down with broadleaf herbicide has been effective in suppressing weeds
and improving soil fertility in rice–wheat cropping systems (Yadav 2004; Hobbs
et al. 2008).
With systematic crop rotations, the benefits of CAcan be achieved on soils or at lo-
cations where success is often difficult. Combining the timeliness and reduced-labor
benefits of CA with advantages of higher yield and reduced inputs when associated
with a better crop rotation significantly increased profit levels (Linden et al. 2000).
1.6 Weed Control
Weed control is considered a serious problem in CA systems and its success largely
depends on effective weed control. Multiple tillage operations are required to con-
trol perennial weeds by reducing the energy reserves in different storage organs
11
or roots of weeds (Todd and Derksen 1986; Fawcett 1987). Weed control in CA
depends upon agronomic practices, herbicides, and level of tillage used (Lafond
et al. 2009). In CA systems, small-seeded weed species are favored (Chauhan et al.
2006a; Farooq and Nawaz 2014), while dormant weed seeds present in the soil do
not move to the soil surface (Cardina et al. 1991). In CA, crop residues are main-
tained on the soil surface that keeps the soil moist and cool, which increases the
survival of germinated small weed seeds compared with conventional agriculture.
In conventional tillage systems, weed seeds are buried in the soil, while in CA more
weed seeds are left on the soil surface (Chauhan et al. 2006b), which are generally
more susceptible to decay (Gallandt et al. 2004).
Chemical weed control is the most effective weed management option in CA;
however, its effectiveness depends upon several factors including application of
appropriate herbicides, time of application (postemergence vs. preemergence), and
the amount of crop residue present on the soil surface. Crop residues directly affect
weed germination and the bioavailability of herbicides such as trifluralin (Chauhan
et al. 2006c). Residue retention strongly impacts weed emergence; several factors
determine the extent of this influence including type and quantity of residue, na-
ture of the residue, soil type, weather conditions, and prevailing weed flora (Buhler
1995; Chauhan et al. 2006d). Phenolics in the surface residue may reduce the weed
infestation (Farooq et al. 2011b) in CA system. Nonetheless, the presence of plant
residues may reduce the persistence and efficacy of soil-applied herbicides, which
do not require incorporation into the soil and also intercept and bind the chemical
before it reaches the soil surface (Potter et al. 2008).
The availability of transgenic crops with resistance to nonselective herbicides,
such as glyphosate and glufosinate, can effectively control weed species while
decreasing labor demands and repeated applications of herbicides (Cerdeira and
Duke 2006). By using transgenic crops in CA, growers have boosted profitability
by reducing labor expenses. The introduction of herbicide-tolerant transgenic crop
varieties in CA systems provided effective weed control with substantial yield in-
creases (Duke and Powles 2008). A new challenge to develop herbicide-resistant
weed biotypes is threatening the use of herbicide-tolerant transgenic crops in CA
systems (Farooq et al. 2011a; Heap 2014). Several weeds have developed resistance
against herbicides. The first case was reported in 1970 in common groundsel (Se-
necio vulgaris L.), which developed triazine resistance (Ryan 1970). Worldwide,
the number of herbicide-resistant weed biotypes has reached 432, which demands
continued research to control the resistance and avoid the future spread of resistant
weeds (Appleby 2005; Heap 2014).
Kirkegaard et al. (2014) opined that herbicide rotation, green/brown manures,
and harvesting and destruction of weed seeds may help in weed management under
CA systems. They further proposed to include strategic tillage as a component of
integrated weed management approach where applicable and safe (with respect to
erosion risk; Kirkegaard et al. 2014). This may help to reduce the incidences of
development of herbicide-resistant weed biotypes.

The Role of Policy and Institutional Support
CA is a multi-dimensional approach ensuring the sustainability of resource use and
food security. Principally, CA offers resistance to the irrational use of natural re-
serves through good management practices such as minimal soil disturbance using
optimized tillage operations, check on soil exposure to environmental calamities,
and biodiversity maintenance through diversified crop rotations. With the ever-
increasing global population and urbanization reducing the amount of land under
agriculture, food security has become a conundrum (Hobbs et al. 2008); the sustain-
able use of available resources is a key element of CA systems.
Adoption of CA is a paradigm shift requiring huge efforts and trade-offs at indi-
vidual and institutional levels. In the long run, CA should be the ultimate solution
to agricultural problems in small landholding farming communities (Derpsch 2003;
Giller et al. 2009). CA research has progressed but adoption at the farmer level is a
serious concern. Many factors hinder the uptake of CA by farmers and authorities:
lack of proper information, poor knowledge dissemination, lack of demonstration,
the need for long-term hard work, temporary decline in economic returns, hesita-
tion, vague policies, lack of institutional support and natural disasters. Institutional
support, innovative policy making, organizational collaboration, motivated think
tanks, and government supervision are critical to develop a strong system for prolif-
eration of CA (Kassam et al. 2012).
Policy making involves the realization of the available resources and serious
approach to rethink the issue and options. Ecological, social, and political activ-
ism on the issue of natural resource depletion and sustainability has been ignited
for 20–30 years at a global level. Understanding this problem provides the foun-
dation for structural development and promotion of sustainable approaches along
with an awareness campaign (Kassam et al. 2012). One important policy is “Save
and Grow” coined by the Food and Agriculture Organization. It covers the idea of
a two-way process of sustainable production and economical usage, which has sim-
plified and clarified the theme of CA. Policy formation strengthens the expression,
adoption, and promotion of this approach (FAO 2011b). Effective policies offer
pragmatic solutions to a number of challenges (Kienzler et al. 2012) such as:
• Useful practices to improve food production under limited inputs and thus sus-
tainable promotion of food production and the supply chain.
• Lowering the intensity of environmental damage through eco-friendly approaches.
• Economizing the production chain via improved cultural practices, judicious in-
put use, and reduced exploitation of on-farm resources.
• Preserving ecological hierarchy by maintaining biodiversity and natural habitats.
• Offering a wide range of adjustments, adaptations, and rehabilitation after fre-
quent natural and secondary disasters.
Plenty of evidence on the serious concerns, issues, and threats necessitating the
adoption of CA are available (Foresight 2011); however, intensified production
is still possible under a conservation regime with benefits including lower capital
costs, reduced inputs, flexibility in terms of adaptation, aggrandized ecosystem ef-
13
ficiency, and environmental protection. In some parts of the world, conservation
tillage has been termed under transformed tillage packages like zero tillage, reduced
tillage, minimum tillage, etc.
Institutions are the main hubs for information gathering, knowledge sharing, and
technology transfer. The role of institutional development in agriculture is signifi-
cant. Linkage between research organizations, educational institutes, and extension
wings must be very strong to launch any technology. Considerable work is being
undertaken on the adoption of CA on national and international fronts. Govern-
ments are sensing the vitality of the system and reinforcing the approach through
multi-actions. In developed countries, the scientific community is leading the task
by innovating and modifying the steps for sustainability. Strict implication of the
rules and regulations has confirmed the success of CA in different cases.
Authorities are sensing their responsibilities, and public sector movements re-
garding CA adoption are flourishing. Different institutions support farming com-
munities to trial subsidized conservation packages. Incentives and visual economic
profitability help to promote adoption and reduce farming community concerns
(Kassam et al. 2012). Adoption of zero tillage in the rice–wheat cropping system in
the Indo-Gangetic Plains is a successful example of CA adoption in the developing
world. It is the result of consistent efforts by global institutions and organizations in
collaboration with local governments and NGOs. Similarly, successful progress is
being made in Central Asia, Africa, and other regions. Conservation approaches are
not only becoming popular but also being adopted at the farmer level, which could
improve with further institutional support and the right policy making in the future.
1.8 Conclusion
CA is a complex suite of technologies, including wise soil manipulation, retention
of crop residues as soil cover, planned and diversified crop sequences, and effective
weed management, for eco-friendly sustainable crop production. CA has proved
beneficial in terms of yield, income, sustainability of land use, ease of farming, and
the timeliness of ecosystem services and cropping practices. CA systems are being
increasingly adopted worldwide; however, in some countries, its adoption is either
slow or nonexistent. Sustained governmental policies and institutional support may
play a key role in the promotion of CA through the provision of required services
for farming communities and certain incentives. On-farm participatory research and
demonstration trials may help accelerate the adoption of CA. The development and
introduction of herbicide-tolerant transgenic crops resulted in the rapid spread of
CA systems; however, the development of herbicide-resistant weed biotypes is pos-
ing a new threat. This invites attention of researchers to develop economically vi-
able innovative alternative tools to prevent and manage herbicide-resistance devel-
opment in weeds and weed management strategies. The use of Sesbania in direct-
seeded rice as a manure intercrop and then using that as mulch with the application
of broadleaf killer herbicide is a good option for weed and fertility management.

Abstract Yield increases and sustainability of conservation agriculture (CA) sys-
tems largely depend on systematic crop rotations and in situ crop harvest residue
management coupled with adequate crop nutrition. In this chapter, the beneficial
effects of crop residue management and crop rotations on maize (Zea mays L.)
grain yield in CA systems under rainfed conditions are explained through a meta-
analysis. The effects of crop residue management are most beneficial under rainfed
conditions as rainfall distribution is often erratic and seasonal dry spells common.
The meta-analysis was based on the weighted mean difference (WMD) effect size
using the random effects model. Yield advantages of CA systems over conventional
tillage systems were only significant when in rotation, under low rainfall conditions
and with large N fertiliser inputs. The WMD for CA with continuous maize ranged
from −1.32 to 1.27 with a mean of −0.03 t ha−1
, and when rotation was included
the WMD ranged from −0.34 to 1.92 with a mean of 0.64 t ha−1
. Mulch retention
under low rainfall (600 mm) had a WMD between −0.2 and 1.0 with a mean of
0.4 t ha−1
while high rainfall (1000 mm per season) reduced the yield advantage
with the WMD ranging from −1.2 to 0.02 with a mean of −0.59 t ha−1
. CA is likely
to have the largest impact in low-rainfall environments where increased infiltration
of rainfall and reduced evaporative losses are achieved by retaining crop residues.
However, it is in these areas that achieving sufficient crop residues is a challenge,
particularly in mixed crop–livestock systems where crop residues are needed for
livestock feed in the dry season. The results suggest that CA needs to be targeted
and adapted to specific biophysical as well as socioeconomic circumstances of
farmers for improved impact. The ability of farmers to purchase fertiliser inputs,
achieve sufficient biomass production as well as produce alternative feed will allow
them to practise CA and possibly achieve large yields.

2.1 Introduction
Systematic crop rotations and in situ crop harvest residue management are the pillars
of conservation agriculture (CA). Yet, they are also the most pronounced barriers to
its widespread practice especially on smallholder farms in the tropics. A crop rota-
tion is the sequence of crop types grown in succession on a specific field (Wibberley
1996; Castellazzi et al. 2008). Crop rotations play a key role in CA systems where
they facilitate soil fertility replenishment while at the same time minimising pest
and disease build-up (Trenbath 1993). Crop rotations with leguminous crops have
the potential to increase soil nitrogen (N) concentration through biological nitrogen
fixation (BNF; Giller 2001). Research results have shown that synthetic fertilis-
ers or organic manure do not solve the challenges of soil degradation and fertility
decline except when used in combination (Chivenge et al. 2009, 2011). The use of
mineral fertiliser is needed and should be combined with management practices that
build up organic carbon and achieve sustainability in the longer term. The underly-
ing hypothesis of this chapter is that yield increases in CA over conventional agri-
culture systems are underpinned by successful crop residue management and crop
rotation, and such yield increases differ according to fertiliser inputs by farmers and
the amount and distribution of seasonal rainfall.
The importance of crop residue retention to sustainability of crop production is
widely acknowledged. In situ retention of crop harvest residues coupled with no
tillage has the potential to increase substantially soil organic carbon (SOC) although
current data and knowledge are inconclusive (Govaerts et al. 2009). However, there
is consensus that consistent and sufficient C inputs are the major determinants of
SOC changes in soil and not so much the type of tillage (Chivenge et al. 2007).
Reduced tillage is important in reducing decomposition rates but this is only rel-
evant if sufficient organic inputs have been applied (Chivenge et al. 2007). The
absence of soil inversion may lead to SOC accumulation in the top layers of the
soil (Franzluebbers and Arshad 1996). Carbon increases are expected over time if
the amount of crop residue retained is more than that dissipated by the oxidation
process. Current literature suggests that the importance of crop residue retention in
the short term might be related to the maintenance of SOC rather than its absolute
increase.
Crop residues provide soil cover which decreases run-off and soil loss especially
on low slopes but it is less effective on steep slopes (Adekalu et al. 2007). In a study
on a utisol in Nigeria, Adekalu et al. (2007) reported that water infiltration increased
with increasing levels of mulch cover (giant elephant grass) and decreased with in-
creasing slope. The authors suggested that to improve infiltration and reduce run-off
and soil erosion, up to 90% cover may be necessary especially if organic matter is
low and sand content is high. Other researchers have suggested mulch application
rates of 4–6 t ha−1
as adequate (Lal 1976; De Silva and Cook 2003) but what these
quantities translate to in terms of soil cover for different crops is not well known
(Morrison et al. 1985). Some authors suggest that mulch rates of up to 6 t ha−1
may completely eliminate soil loss (Fig. 2.1, Lal 1998; Adekalu et al. 2006, 2007).
Understanding the interactions between the type and rate of mulch application, the
2 Crop Rotations and Residue Management in Conservation Agriculture 23
contribution to nutrient enhancement in soil and the potential for crop yield
improvement are needed (Cook et al. 2006). Crop residues have low thermal con-
ductivity such that mulching can reduce soil temperature for optimal germination
and root development in hot environments (Lal 1978; Riddle et al. 1996). They in-
sulate the soil surface and increase resistance to heat and vapour transfer leading to
increased available soil water (Hatfield and Prueger 1996; Dexter 1997; Cook et al.
2006). Mulch is also important for intercepting rainfall energy and reduces erosion.
In areas of relatively short duration and low-intensity rainfall, mulching may reduce
soil water recharge; this could be crucial in areas with frequent and small amounts
of rainfall because it can be intercepted before it recharges the topsoil (Sadler and
Turner 1993; Savabi and Stott 1994). It has also been suggested that the crop resi-
due thickness has a direct effect on total interception of rainfall (Savabi and Stott
1994). Thus, mulch application is not always positive and may be detrimental to
crop productivity.
In cereal-based systems which dominate the tropics, most crop residues are de-
rived from maize, millet and sorghum, which are rich in lignin and have high C/N
ratios that are generally greater than 60 (Cadisch and Giller 1997; Handayanto et al.
1997). Although crop residues are often on the soil surface, they are more likely to
partially incorporate and decompose as the season progresses adding to SOC (Park-
er 1962). However, the wide C/N ratio leads to prolonged N immobilization by
microorganisms, rendering N unavailable for crop growth in the short term (Giller

et al. 1997). Thus, high N inputs are required when poor-quality crop residues are
used as mulch cover.
This chapter collates and performs a meta-analysis on existing literature on the
effect of crop rotations and crop residue management on maize grain yield under
CA. Meta-analysis allows combined quantitative analyses of experimental yield
data reported in the literature and estimation of effect sizes (Glass 1976; Rosenburg
et al. 2000; Ried 2006; Borenstein et al. 2009). The analysis increases the statistical
power available to test hypotheses and can help unravel differences in responses
between treatments under different environments (Gates 2002; Borenstein et al.
2009). The effect size for each individual study is considered an independent
estimate of the underlying true effect size, subject to random variation. All studies
contribute to the overall estimate of the treatment effect whether the result of each
study is statistically significant or not thus reducing publication bias. Data from
studies with more precise measurements or larger studies (many cases) are given
more weight, so they have more influence on the overall estimate (Gates 2002).
However, meta-analysis has potential weaknesses due to publication bias and other
biases that may be introduced in the process of locating, selecting and combining
studies (Egger et al. 1997; Noble 2006). Publication bias arises when researchers,
reviewers and editors submit or accept manuscripts for publication based on the
direction or strength of the study findings (Dickersin 1990). This means that studies
reporting contradictory or neutral results are likely to be omitted from publications.
To reduce publication bias, data searches were carried out online to find results
from all parts of the world under rainfed conditions. Some researchers were also
contacted to provide some grey literature. Moderators, i.e. factors likely to influ-
ence effect sizes such as mean annual precipitation (MAP) and N fertiliser input,
were identified during data collation and the random effects model was used during
the analysis (Ried 2006).
2.2 Meta-analysis
Maize grain yield data were obtained from studies on the effect of crop residue
management and crop rotation. Due to the voluminous nature of the search results,
meta-analysis was restricted to rainfed conditions in semiarid and subhumid envi-
ronments where the effects of mulch on crop productivity would be better assessed.
Data searches were predominantly online and obtained from refereed journals, book
chapters or peer-reviewed conference proceedings. The following keywords and
their combinations were searched: crop rotations, legumes, CA, mulch cover, no
tillage, maize yield, corn yield, subhumid, semiarid and rainfed. The treatments
from which maize grain yield data were collated are described in Table 2.1. Nutrient
inputs needed to be the same across the treatments tested in each study. Unpub-
lished data or grey literature was obtained from researchers working on CA. Result
moderators or factors likely to influence the meta-analysis outcome such as annual
rainfall and N input as reported in the literature were included in the analysis. Fifty
publications met the selection criteria and were used in the meta-analysis (Table 2.2).
2 Crop Rotations and Residue Management in Conservation Agriculture 25
The meta-analysis procedure and calculation followed that described by
Rusinamhodzi et al. (2011) as presented below. Data required for the meta-analysis
were in the form of treatment mean ( X ), standard deviation ( SDX ), and number
of replicates ( n ) mentioned in the experimental design. Several authors presented
statistical data in different formats such as standard error SEX and coefficient of
variation ( CV % ). These were converted to standard deviation ( SDX
) using the

.  Effect size was
obtained by computing the weighted mean difference (WMD) using the random
effects model (DerSimonian and Laird 1986; Borenstein et al. 2009). The mean
difference (Eq. 2.1) in yield between the treatment and control was used due to its
ease of interpretation and the relevance for comparing potential gains (Ried 2006;
Sileshi et al. 2008). To obtain overall treatment effects across studies, the differ-
ences between treatment and control were weighted (Eq. 2.3). The weight given
to each study was calculated as the inverse of the variance (Eq. 2.2). The random
effects model assumed that the true effect of CA on crop yield varied from site
to site and from season to season; thus, contributions of each study to the overall
effect size were considered independent. Nitrogen input and amount of seasonal
rainfall were chosen as the most important moderators and their effect tested on the
magnitude of the responses (mean differences). Nitrogen input and MAP classes
were categorized as reported by Rusinamhodzi et al. (2011) with MAP classes as
low (600 mm), medium (600–1000 mm) and high (1000 mm), and N fertiliser
input as low (100 kg ha−1
) and high (100 kg ha−1

Yield Data from Different Mulch and Crop Rotations
The WMD of CA with continuous maize cropping was almost zero but ranged from
−1.32 to 1.27 t ha−1
(Fig. 2.2). Including the rotation into the CA system increased
the WMD which ranged from −0.34 to 1.92 t ha−1
with a mean of 0.64 t ha−1
.
Retention of mulch alone without crop diversification does not necessarily lead to
improved crop productivity. The overall effect of mulch on crop productivity could
be considered neutral in this case. These results agree with Kapusta et al. (1996)
who observed no significant yield difference between no tillage and conventional
ploughing on poorly drained soils after 20 years of continuous no tillage. Similarly,
Dam et al. (2005) reported that, after 11 years, maize yields were more affected
by the amount of rainfall and temperature across years than tillage and crop resi-
due management. Rotations especially with legumes often have positive effects on
maize yield across soil fertility regimes (Karlen et al. 1991, 1994a). The larger yield
in rotation compared with continuous monocropping was attributed to reduced pest
infestations, improved water-use efficiency, good soil quality as shown by increased
organic carbon, greater soil aggregation, increased nutrient availability and greater
soil biological activity (Van Doren et al. 1976; Hernanz et al. 2002; Kureh et al.
2006). In the Highlands of Madagascar, Djigal et al. (2012) observed CA systems
that supported comparable or better yields in the long term than conventional tillage
if crop rotation was correctly managed.

Subgroup analysis of continuous maize production with mulch suggested that
the amount of seasonal rainfall and fertiliser inputs are important yield modera-
tors. The most yield advantage (WMD between −0.2 and 1.0 t ha−1
) from mulch
retention was obtained in environments where seasonal precipitation did not exceed
600 mm, with an overall effect of 0.4 t ha−1
(Fig. 2.3). The yield advantages from
mulch application decreased with increasing seasonal rainfall as expected; above
600 mm, there was no yield advantage from mulch retention over conventional
tillage. The retention of mulch increases rainfall infiltration into the soil and reduces
evaporative losses resulting in waterlogging. In other studies, yields under CA prac-
tices were 5–20% less than under conventional tillage practices in wet years, but
10–100% higher in relatively dry years (Hussain et al. 1999). Similarly, Lueschen
et al. (1991) reported larger crop yields with CA practices than conventional tillage
in a relatively dry year.
Retention of mulch requires a concomitant increase in N inputs to ensure larger
yields. WMD for systems where N input was less than 100 kg ha−1
indicated that
conventional systems would yield more than CA options tested (Fig. 2.4). When N
fertiliser input was raised beyond 100 kg ha−1
, the WMD had a yield advantage for
CA over conventional tillage. The results agree with Vanlauwe et al. (2014) who
identified adequate nutrient management in CA systems as another critical factor,
i.e. the need for a fourth principle. Similarly, Díaz-Zorita et al. (2002) reported that
maize yields increased more with nitrogen fertilisation than tillage under subhumid

and semiarid regions of Argentina. The most notable crop residues in semiarid areas
are those of maize, millet and sorghum of poor quality due to high C/N ratios,
generally greater than 60, which immediately immobilizes N (Cadisch and Giller
1997; Handayanto et al. 1997). Thus, high N inputs are required when poor-quality
crop residues are used as mulch.
2.4 
Constraints to Systematic Crop Rotations
Poorly developed markets, minimal household food contributions and limited
land sizes are the major impediments to successful crop rotations by smallholder
farmers. Widespread poverty prevents farmer access to credits and inputs such as
fertiliser, seed and pesticides (Graham and Vance 2003; Sanginga and Woomer
2009). Specialized agrifood markets such as those in Laos limit the integration of
grasses and legumes into diversified crop rotations (Lestrelin et al. 2012). Limited
landholdings are becoming a major problem due to the rising population pressure—
a classic example is in Malawi where land sizes are often below 1 ha limiting the
number of crops farmers can grow in a season (Ellis et al. 2003; World Bank 2007).
Soil fertility decline is another major challenge in the field where deficiencies of
phosphorus (P), potassium (K), sulphur (S) and micronutrients such as zinc (Zn),
molybdenum (Mo) and boron (B) may limit legume growth and N2
fixation (O’Hara
et al. 1988). P availability is often regarded as the most limiting factor (Giller and

Cadisch 1995). At the farm level, it is important that grain legumes provide multiple
benefits especially as a food and are acceptable to farmers (Giller 2001). Formal seed
systems are poorly developed with limited varieties of maize seed available, often
open-pollinated varieties. Most farmers use retained seed, informal seed exchanges
with other farmers and seed bought from local markets. They see their local seed as
better adapted to their conditions but lack of quality uniformity means they are
less preferred at the market (cf. Rohrbach and Kiala 2007). Widespread adoption
of legume production will be achieved by strengthening seed systems, improving
farmer access to input markets for improved, short-season and disease-resistant
varieties and P fertiliser and output markets for better prices and trade terms.
2.5 
Constraints to Crop Residue Management
A comprehensive appraisal of the benefits and constraints related to crop resi-
due management has been explored (Erenstein 2002; Lal 2005). Major con-
straints to successful crop residue management in CA systems are related
to the small baseline crop productivity and other alternative economic uses
of crop residues such as livestock feed, fuel, bedding in kraals (animal pad-
docks) during the rainy season and construction (fencing and thatching) for
some farming households (Mazvimavi et al. 2008; Erenstein 2011; Rufino et al.
2011; Johansen et al. 2012). Crop and livestock production are closely integrated in
mixed smallholder farming systems in much of the tropics (Thornton and Herrero
2001; Rufino et al. 2011). Crop residues are needed to provide livestock feed during
the dry season where feed is severely limited while manure is needed for crop pro-
duction (Rufino et al. 2011; Rusinamhodzi et al. 2013). The application of livestock
manure has been shown to increase crop productivity especially targeted to respon-
sive fields (Zingore et al. 2008; Rusinamhodzi et al. 2013). Such yield benefits
derived from manure, whose quantity and quality partly depends on crop harvest
residues (Nzuma and Murwira 2000; Lekasi et al. 2003; Rufino et al. 2007), suggest
that farmers face trade-offs in crop residue management and it might be benefi-
cial for them to follow the manure production pathway than apply crop residues as
mulch (Naudin et al. 2012; Valbuena et al. 2012; Rusinamhodzi 2013). Moreover,
livestock provides a source of cash income and spreads the risk (Sumberg 2002;
Rufino et al. 2006). In most situations, alternative grazing does not exist as commu-
nal rangelands are often degraded and characterized by poor-quality fodder (Rufino
et al. 2011). Although development agents have made potential legume, grass and
other agroforestry trees available for use as a fodder, farmers reject them because
they do not contribute directly to food security despite the enormous labour inputs
required (Giller 2001). The unimodal nature of the cropping seasons suggest that
farmers concentrate all their limited resources to major food production and other
crops are considered much later in the season leading to small productivity.
On the other hand, the availability of crop residues is not a technological panacea.
The overall effect depends on the local biophysical and socioeconomic environ-
2 Crop Rotations and Residue Management in Conservation Agriculture 31
ment; i.e. they differ substantially between the agricultural settings of developed
and developing countries (Erenstein 2002). In South Asia, Aulakh et al. (2012)
concluded after a 4-year study that future efforts are required to develop new tech-
nologies to alleviate the negative effects of relatively cooler environments created
by surface-retained crop residues especially during germination and initial growth in
the subtropical region. In the Trans-Gangetic plains of India, crop residue manage-
ment practices are largely incompatible with year-round mulch retention needed in
CA despite significant biomass production (Erenstein 2011) due to other important
activities for the household.
2.6 Future Outlook
Much of the research on CAhas been conducted at plot level, focusing on the effects
of CA on soil quality, with little effort on how CA fits into broader farming systems
(Giller et al. 2009; Baudron et al. 2012). Retention of crop residues as a mulch in
the field is not feasible for most farmers due to competition for livestock feed and
the need for more fertiliser, making CA unattractive for most farmers. Retention of
crop residues will lead to depressed yields in the short term due to immobilization
of N which contrasts sharply with farmers’ needs. Therefore, the short-term needs
of farmers may be a threat to CA uptake. While the short-term crop yield response
to CA is highly variable, yields often improve in the long term when the continued
accumulation of crop residue increases the availability of SOC and nutrients for
crop growth.
Until recently, the discourse around CA has been the inadequate amounts of crop
residue produced against multiple important uses, i.e. creating trade-offs for their
use. The success of CA was considered directly related to the ability to provide
enough soil cover, and little attention has been paid to adequate nutrient manage-
ment, firstly to offset the N deficit caused by immobilization due to poor-quality
residues and secondly to provide a balanced nutrient supply to the growing crop.
Recently, Vanlauwe et al. (2014) suggested the need for a fourth principle to add
to the principles of no till, mulch retention and crop rotation. Optimum fertiliser
application may help to increase biomass production which may allow both the
retention of crop harvest residues for mulch as well as providing livestock feed.
Both crop rotations and fertiliser inputs are important for improved yields in CA
systems. Future research needs should be devoted to identifying appropriate nutri-
ent management strategies in CA systems together with crop residue retention and
crop rotations to boost crop productivity (Vanlauwe et al. 2014). Efforts are needed
to increase fertiliser use by smallholder farmers especially in Africa where figures
as low as 8 kg ha−1
are often mentioned (Groot 2009; Sanginga and Woomer 2009).

2.7 Conclusions
The meta-analysis suggested that to achieve any meaningful yield increases in CA
systems, crop residues must be retained in situ coupled with crop rotations and
increased N fertiliser inputs to offset the immobilization effect of crop residues.
Moreover, CA is likely to have the largest impact in low-rainfall environments
where increased infiltration of rainfall and reduced evaporative losses will be
achieved by retaining crop residues. However, it is in these areas where achieving
sufficient crop residues is also a challenge, particularly in mixed crop–livestock
systems where crop residues are needed for livestock feed in the dry season. CA
needs to be targeted and adapted to specific biophysical as well as socioeconomic
circumstances of farmers for improved impact. The ability of farmers to purchase
fertiliser inputs, achieve sufficient biomass production as well as produce alterna-
tive feed will allow them to practise CA and achieve large yields. Considerable
efforts are needed in the future to develop nutrient management strategies tailored
for the practice of CA.

INTRODUCTION.
No man can see all of a mountain at once. He sees its differing
sides. Moreover, it has rainy and bright day aspects, and summer
and winter faces.
The romancer is covered with the dust of old books, modern books,
great books, and out of them all brings in a condensing hand these
pictures of two men whose lives were as large as this continent.
La Salle is a definite figure in the popular mind. But La Salle’s
greater friend is known only to historians and students. To me the
finest fact in the Norman explorer’s career is the devotion he
commanded in Henri de Tonty. No stupid dreamer, no ruffian at
heart, no betrayer of friendship, no mere blundering woodsman—as
La Salle has been outlined by his enemies—could have bound to
himself a man like Tonty. The love of this friend and the words this
friend has left on record thus honor La Salle. And we who like
courage and steadfastness and gentle courtesy in men owe much
honor which has never been paid to Henri de Tonty.
Book I.
A MONTREAL BEAVER FAIR.
1678 A. D.
THE STORY OF TONTY.
I.
FRONTENAC.
Along the entire river front of Montreal camp-fires faded as the
amphitheatre of night gradually dissolved around them.
Canoes lay beached in one long row as if a shoal of huge fish had
come to land. The lodges made a new street along Montreal wharf.
Oblong figures of Indian women moved from shadow to shine, and
children stole out to caper beside kettles where they could see their
breakfasts steaming. Here and there light fell upon a tranquil
mummy less than a metre in length, standing propped against a
lodge side, and blinking stoical eyes in its brown flat face as only a
bark-encased Indian baby could blink; or it slept undisturbed by the
noise of the awakening camp, looking a mummy indeed.
The savage of the New World carried his family with him on every
peaceable journey; sometimes to starve for weeks when the winter
hunting proved bad. It was only when he went to war that he denied
himself all squaw service.
The annual beaver fair was usually held in midsummer, but this year
the tribes of the upper lakes had not descended with their furs to
Montreal until September. These precious skins, taken out of the
canoes, were stored within the lodges.
Every male of the camp was already greasing, painting, and
feathering himself for the grand council, which always preceded a
beaver fair. Hurons, Ottawas, Crees, Nipissings, Ojibwas,
Pottawatamies, each jealous for his tribe, completed a process
begun the night before, and put on what might be called his court
dress. In some cases this was no dress at all, except a suit of
tattooing, or a fine coat of ochre streaked with white clay or soot.
The juice of berries heightened nature in their faces. But there were
grand barbarians who laid out robes of beaver skin, ample, and
marked inside with strange figures or porcupine quill embroidery.
The heads swarming in this vast and dusky dressing-room were
some of them shaven bare except the scalp lock, some bristling in a
ridge across the top, while others carried the natural coarse growth
tightly braided down one side, with the opposite half flowing loose.
Montreal behind its palisades made a dim background to all this
early illumination,—few domestic candles shining through windows
or glancing about the Hôtel Dieu as the nuns began their morning
devotions. Mount Royal now flickered a high shadow, and now
massed inertly against stars; but the river, breathing forever like
some colossal creature, reflected all the camp-fires in its moving
scales.
The guns of the fort had fired a salute to Indian guests on their
arrival the evening before. But at sunrise repeated cannonading, a
prolonged roll of drums, and rounds of musketry announced that the
governor-general’s fleet was in sight.
Montreal flocked to the wharf where already the savages were
arrayed in solemn ranks. Marching out of the fortress with martial
music, past the Hôtel Dieu to the landing-place where Frontenac
must step from his boat, came the remnant of the Carignan
regiment. Even the Sulpitian brotherhood, whose rights as seigniors
of Montreal island this governor had at one time slighted, appeared
to do him honor. And gentle nuns of St. Joseph were seen in the
general outpour of inhabitants.
This governor-general, with all his faults, had a large and manly way
of meeting colonial dangers, and was always a prop under the
fainting heart of New France.
His boats made that display upon the St. Lawrence which it was his
policy and inclination to make before Indians. Officers in white and
gold, and young nobles of France, powdered, and flashing in the
colors of Louis’ magnificent reign, crowded his own vessel,—young
men who had ventured out to Quebec because it was the fashion at
court to be skilled in colonial matters, and now followed Frontenac
as far as Montreal to amuse themselves with the annual beaver fair.
The flag of France, set with its lily-like symbol, waved over their
heads its white reply to its twin signal on the fort.
Frontenac stood at the boat’s prow, his rich cloak thrown back, and
his head bared to the morning river breath and the people’s shouts.
Being colonial king pleased this soldier, tired of European camps and
the full blaze of royalty, where his poverty put him to the
disadvantage of a singed moth.
He came blandly gliding to the wharf, Louis de Buade, Count of
Frontenac, and Baron of Palluau, and the only governor of New
France who ever handled the arrogant Five Nations of the Iroquois
like a strong father,[1]—a man who would champion the rights of his
meanest colonist, and at the same time quarrel with his lieutenant in
power to his last breath.
Merchants of Quebec followed him with boat-loads of Indian
supplies. Even Acadia had sent men to this voyage, for the Baron de
Saint-Castin appeared in the fleet, with his young Indian Baroness. It
is told of Saint-Castin that he had kept a harem in his sylvan
principality of Pentegoet; but being a man of conscience, he
confessed and reformed. It is also told of him that he never kept a
harem or otherwise lapsed into the barbarisms of the Penobscots,
among whom he carried missionaries and over whom he was a great
lord. Type of the Frenchman of his day, he came to New France a lad
in the Carignan regiment, amassed fortunes in the fur trade, and
holding his own important place in the colony, goaded like a thorn
the rival colony of New England along his borders.
But most conspicuous to the eyes of Montreal were two men
standing at Frontenac’s right hand, a Norman and an Italian. Both
were tall, the Italian being of deeper colors and more generous
materials. His large features were clothed in warm brown skin. Rings
of black hair thick as a fleece were cut short above his military collar.
His fearless, kindly eyes received impressions from every aspect of
the New World. There dwelt in Henri de Tonty the power to make
men love him at sight,—savages as well as Europeans. He wore the
dress of a French lieutenant of infantry, and looked less than thirty
years old, having entered the service of France in his early youth.
The other man, Robert Cavelier,—called La Salle from an estate he
had once owned in France,—explorer, and seignior of Fort Frontenac
and adjacent grants on the north shore of Lake Ontario, was at that
time in the prime of his power. He was returning from France, with
the king’s permission to work out all his gigantic enterprises, with
funds for the purpose, and one of the most promising young military
men in Europe as his lieutenant.
Montreal merchants on the wharf singled out La Salle with jealous
eye, which saw in the drooping point and flaring base of his nose an
endless smile of scorn. He was a man who had only to use his
monopolies to become enormously rich, cutting off the trade of the
lakes from Montreal. That he was above gain, except as he could
use it for hewing his ambitious road into the wilderness, they did not
believe. The merchants of Montreal readily translated the shyness
and self-restraint of his solitary nature into the arrogance of a
recently ennobled and successful man.
La Salle had a spare face, with long oval cheeks, curving well inward
beside the round of his sensitive prominent chin. Gray and olive
tones still further cooled the natural pallor of his skin and made
ashen brown the hair which he wore flowing.
The plainness of an explorer and the elegance of a man exact in all
his habits distinguished La Salle’s dress against that background of
brilliant courtiers.
He moved ashore with Frontenac, who saluted benignly both the
array of red allies and the inhabitants of this second town in the
province.
The sub-governor stepped out to escort the governor-general to the
fort, bells rang, cannon still boomed, martial music pierced the heart
with its thrill, and the Carignan squad wheeled in behind Frontenac’s
moving train.
“Sieur de la Salle! Sieur de la Salle!” a little girl called, breaking away
from the Sisters of St. Joseph, whose convent robes had enclosed
her like palisades, “take me also in the procession!”
This demand granted itself, so nimbly did she escape a nun’s
ineffectual grasp and spring between Tonty and La Salle.
Frontenac himself had turned at the shrill outcry. He laughed when
he saw the wilful young creature taking the explorer by the wrist and
falling into step so close to his own person.
A pursuing nun, unwilling to interrupt the governors train, hovered
along its progress, making anxious signs to her charge, until she
received an assuring gesture from La Salle. She then went back
dissatisfied but relieved of responsibility; and the child, with a proud
fling of her person, marched on toward the fort.
II
HAND-OF-IRON.
“Mademoiselle the tiger-cat,” said La Salle to Tonty, making himself
heard with some effort above the din of martial sound.
The young soldier lifted his hat with his left hand and made the child
a bow, which she regarded with critical eyes.
“I am the niece of Monsieur de la Salle,” she explained to Tonty as
she marched; “so he calls me tiger-cat.”
“Mademoiselle Barbe Cavelier is the tiger-cat’s human name,” the
explorer added, laughing. “It is flattering to have this nimble animal
spring affectionately on one from ambush; but I should soon have
inquired after you at the convent, mademoiselle.”
“I did not spring affectionately on you,” said Barbe; “I wanted to be
in the procession.”
“Hast thou then lost all regard for thy uncle La Salle during his year
of absence?”
Barbe’s high childish voice distinctly and sincerely stated, “No,
monsieur; I have fought all the girls at the convent on your account.
Jeanne le Ber said nothing against you; but she is a Le Ber. I am
glad you came back in such grandeur. I was determined to be in the
grandeur myself. But it is not a time to give you my cheek for a kiss.”
La Salle smiled over her head at Tonty. The Italian noted her marked
resemblance to the explorer. She had the same features in delicate
tints, the darkness of her eyelashes and curls only emphasizing the
type. Already her small nose drooped at the point and flared at the
base. As La Salle and his young kinswoman stepped together, Tonty
gauged them alike,—two self-restraining natures with unmeasured
endurance and individual force like the electric current.
Montreal’s square bastioned fort, by the mouth of a small creek
flowing into the St. Lawrence, was soon reached from the wharf. It
stood at the south end of the town.
“My dear child,” said La Salle, stating his case to Barbe, “it is
necessary for me to go into the fort with Count Frontenac, and
equally necessary you should go back at once to the Sisters. I will
bring you out of the convent to-morrow to look at the beaver fair.
This is Monsieur de Tonty, my lieutenant; let him take you back to
the nuns. I shall be blamed if I carry you into the fort.”
Barbe heard him without raising objections. She looked at Tonty,
who gave her his left hand and drew her out of the train.
It swept past them into the fortress gates,—gallant music, faces
returning her eager gaze with smiles, plumes, powdered curls, and
laces, gold and white uniforms, soldiers with the sun flashing from
their gun-barrels.
Barbe watched the last man in. To express her satisfaction she then
rose to the tip of one foot and hopped three steps. She was lightly
and delicately made, and as full of restless grace as a bird. Her face
and curls bloomed above and strongly contrasted with the raiment
her convent guardians planned for a child dependent, not on their
charity, but on their maternal care.
The September morning enveloped the world in a haze of
brightness, like that perfecting blue breath which we call the bloom
upon the grape. A great landscape with a scarf of melting azure
resting around its horizon, or ravelling to shreds against the
mountain’s breast, or pretending to be wood-smoke across the river,
drew Tonty’s eye from the disappearing pageant.
That fair land was a fit spot whereon the most luxurious of
civilizations should touch and affiliate with savages of the wilderness.
Up the limpid green river the Lachine Rapids showed their teeth with
audible roar. From that point Mount Royal could be seen rising out of
mists and stretching its hind-quarters westward like some vast
mastodon. But to Tonty only its front appeared, a globe dipped in
autumn colors and wearing plumes of vapor. The sky of this new
hemisphere rose in unmeasured heights which the eye followed in
vain; there seemed no zenith to the swimming blinding azure.
A row of booths for merchants had been built all along the outside of
Montreal’s palisades, and traders were thus early setting their goods
in array.
At the north extremity of the town that huge stone windmill built by
the seigniors for defence, cast a long dewy shadow toward the west.
Its loopholes showed like dark specks on the body of masonry.
Sun-sparkles on the river were no more buoyant and changeable
than the child at Tonty’s side. Dimples came and went in her cheeks.
Her blood was stirred by the swarming life around her.
“Monsieur,” she confided to her uncle’s lieutenant, “I am meditating
something very wicked.”
“Certainly that is impossible, mademoiselle,” said Tonty,
accommodating his step to her reluctant gait.
“I am meditating on not going back to the convent.”
“Where would you go, mademoiselle?”
“Everywhere, to see things.”
“But my orders are to escort you to the nuns. You would disgrace
me as a soldier.”
Barbe lifted her gaze to his face and was diverted from rebellion.
Tonty put out his arm to guard her, but a tall stalking brave was
pushed against her in passing and immediately startled by the thud
of her prompt fist upon his back. The Indian turned, unsheathing his
knife.
“Get out of my way, thou ugly big warrior,” said Barbe, meeting his
eye, which softened from fierceness to laughter, and holding her fist
ready for further encounter.
The Indian made some mocking gestures and menaced her playfully
with his thumb. Tonty threw his arm across her shoulder and moved
her on toward the convent. Barbe escaped from this touch, an
entirely new matter filling her mind.
“Monsieur, even old Jonaneaux in our Hôtel Dieu hath not such a
heavy hand as thou hast. Many a time hath he pulled me down off
the palisade when I looked over to see the coureurs de bois go
roaring by. But thou hast a hand like iron!”
Tonty flushed, being not yet hardened to his misfortune.
“It is a hand of iron. I am called Main-de-fer.”[2]
Barbe took hold of it in its glove. Of all the people she had ever met
Tonty was the only person whose touch she did not resent.
“The other hand is not like unto it, monsieur?”
He gave her the other also, and she compared their weight. With a
roguish lifting of her nostrils she inquired,—
“Will every bit of you turn to metal like this heavy hand?”
“Alas, no, mademoiselle; there is no hope of that.”
Tonty stripped his gauntlet off. With half afraid fingers she examined
the artificial member. It was of copper.
“Where is the old one, monsieur?”
“It was blown off by a grenade at Messina last year.”
“Does it hurt?”
“Not now. Except when I think of the service of Monsieur de la Salle,
and of my being thus pieced out as a man.”
Barbe measured his height and breadth and warm-toned face with
satisfied eyes. She consoled him.
“There is so much of you, monsieur, you can easily do without a
hand.”
III.
FATHER HENNEPIN.
“Thou art a comfort to a soldier, mademoiselle,” said Tonty, heartily.
“But not to a priest,” observed Barbe. “For last birthday when I was
eleven my uncle Abbé stuck out his lip and said I was eleven years
bad. But my uncle La Salle kissed my cheek. There goeth François le
Moyne.” Her face became suddenly distorted with grimaces of
derision beside which Tonty could scarcely keep his gravity. A boy of
about her own age ran past, dropping her a sneer for her pains.
“Monsieur, these Le Moynes and Sorels and Bouchers and Varennes
and Joliets and Le Bers, they are all against my uncle La Salle. The
girls talk about it in the convent. But he hath the governor on his
side, so what can they do? I have pinched Jeanne le Ber at school,
but she will never pinch back and it only makes her feel holier. So I
pinch her no more. Do you know Jeanne le Ber?”
“No,” said Tonty, “I have not that pleasure.”
“Oh, monsieur, it is no pleasure. She says so many prayers. When I
have prayers for penances they make me so tired I have to get up
and hop between them. But Jeanne le Ber would pray all the time if
her father did not pull her off her knees. My father and mother died
in France. If they were alive they would not have to pull me off my
knees.”
“But a woman should learn to pray, even as a man should learn to
fight,” observed Tonty. “He stands between her and danger, and she
should stand linking him to heaven.”
“I can fight for myself,” said Barbe. “And everybody ought to say his
own prayers; but it makes one disagreeable to say more than his
share. I wish to grow up an agreeable person.”
They had reached the palisade entrance which fronted the river,
Barbe’s feet still lagging amid the lively scenes outside. She allowed
Tonty to lead her with his left hand, thus sheltering her next the
booths from streams of passing Indians and traders.
Beside this open gate she would have lingered indefinitely,
chattering to a guardian who felt her hatred of convent restraint,
and gazing at preparations for the council: at prunes and chopped
pieces of oxen being put to boil for an Indian feast; at the governor’s
chair from the fortress, where the sub-governor lived, borne by men
to the middle of that space yearly occupied as the council ring. But a
watchful Sister was hovering ready inside the palisade gate, and
reaching forth her arm she drew her charge away from Tonty, giving
him brief and scandalized thanks for his service.
Barbe looked back. It was worth Tonty’s while to catch sight of that
regretful face smeared about its warm neck by curls, its lips parted
to repeat and still repeat, “Adieu, monsieur. Adieu, monsieur.”
But two men had come between the disappearing child and him, one
man, dressed partly like an officer and partly like a coureur de bois,
throwing both arms around Tonty in the eager Latin manner.
“My cousin Henri de Tonty, welcome to the New World. I waited with
my gouty leg at the fortress for you; but when you came not, like a
good woodsman, I tracked you down.”
“My cousin Greysolon du Lhut! Glad am I to find you so speedily.
This cold and heavy hand belies me.”
“I heard of this hand. But the other was well lost, my cousin. Take
courage in beholding me; I had nearly lost a leg, and not by good
powder and shot either, but with gout which disgracefully loads up a
man with his own dead members. But the Iroquois virgin, Catharine
Tegahkouita, hath interceded for me.”
“Monsieur de Tonty will observe we have saints among the savages
in New France,” said the other man.
He was a Récollet friar with sandalled feet, wearing a gray capote of
coarse texture which was girt with the cord of Saint Francis. His
peaked hood hung behind his shoulders leaving his shaven crown to
glisten with rosy enjoyment of the sunlight. A crucifix hung at his
side; but no man ever devoted his life to prayer who was so
manifestly created to enjoy the world. He had a nose of Flemish
amplitude depressed in the centre, fat lips, a terraced chin, and
twinkling good-humored eyes. The gray capote could not conceal a
pompous swell of the stomach and the strut of his sandalled feet.
“My cousin Tonty,” said Du Lhut, “this is Father Louis Hennepin from
Fort Frontenac. He hath come down to Montreal[3] to meet Monsieur
de la Salle and engage himself in the new western venture.”
“Venture!” exclaimed a keen-visaged man in the garb of a merchant-
colonist who was carrying a bale of goods to one of the booths,—for
no man in Montreal was ashamed to get profit out of the beaver fair.
“Where your Monsieur de la Salle is concerned there will be venture
enough, but no results for any man but La Salle.”
He set his bale down as if it were a challenge.
Points of light sprung into Tonty’s eyes and the blood in his face
showed its quickening.
“Monsieur,” he spoke, “if you are a gentleman you shall answer to
me for slandering Monsieur de la Salle.”
“Monsieur,” spoke Tonty, “if you are a gentleman you shall
answer to me for slandering Monsieur de la Salle.”—Page
32.
“Jacques le Ber is a noble of the colony,” declared Du Lhut, with the
derisive freedom this great ranger and leader of coureurs de bois
assumed toward any one; “for hath he not purchased his patent of
King Louis for six thousand livres? But look you, my cousin Tonty, if
the king allowed not us colonial nobles to engage in trade he would
lose us all by starvation; for scarce a miserable censitaire on our
lands can pay us his capon and pint of wheat at the end of the year.”
“I will answer to you, monsieur,” said Jacques le Ber to the soldier,
”that La Salle is the enemy of the colony, and the betrayer of them
that have been his friends.”
Father Hennepin and Du Lhut caught Tonty’s arms. Du Lhut then
dragged him with expostulations inside the palisade gate, repeating
Frontenac’s strict orders that all quarrels should be suppressed
during the beaver fair, and as the young man’s furious looks still
sought the merchant, reminding him of the harm he might do La
Salle by an open quarrel with Montreal traders.
“I, who am not bound to La Salle as close as thou art,—I tell you it
will not do,” declared Du Lhut.
“Let the man keep his distance, then!”
“Why, you hot-blooded fellow! why do you take these Frenchmen so
seriously?”
“Sieur de la Salle is my friend. I will strike any man who denounces
him.”
“Oh, come out toward the mountain. Let us make a little pilgrimage,”
laughed Du Lhut. “We must cool thee, Tonty, we must cool thee; or
La Salle’s enemies will lie in one heap the length of Montreal, mowed
by this iron hand!”
As Jacques le Ber carried forward his bale, Father Hennepin walked
beside him dealing forth good-natured remonstrance with fat hands
and out-turned lips.
“My son, God save me from the man who doth nurse a grievance.
Your case is simply this: our governor built a fort at Cataraqui, and it
is now called Fort Frontenac. He put you and associates of yours in
charge, and you had profit of that fort. Afterward, by his
recommendation to the king, Sieur de la Salle was made seignior of
Fort Frontenac and lands thereabout. This hast thou ever since
bitterly chewed to the poisoning of thy immortal soul.”
“You churchmen all,—Jesuits, Sulpitians, or Récollets,—are over
zealous to domineer in this colony,” spoke Jacques le Ber, through
the effort of carrying his bale.
“My son,” said Father Hennepin, swelling his stomach and inflating
his throat, “why should I enter the mendicant order of Saint Francis
and live according to the rules of a pure and severe virtue, if I felt
no zeal for saving souls?”
“I spoke of domineering,” repeated the angry merchant.
“And touching Monsieur de la Salle,” said Father Hennepin, “I exhort
thee not to love him; for who could love him,—but to rid thyself of
hatred of any one.”
“Father Hennepin has not then attached himself to La Salle’s new
enterprise?”
“I have a grand plan of discovery of my own,” said the friar, deeply,
rolling his shaven head, “an enterprise which would terrify anybody
but me. The Sieur de la Salle merely opens my path. I will confess to
thee, my son, that in youth I often hid myself behind the doors of
taverns,—which were no fit haunts for men of holy life,—to hearken
unto sailors’ tales of strange lands. And thus would I willingly do
without eating or drinking, such burning desire I had to explore new
countries.”
The Father did not observe that Jacques le Ber had reached his own
booth and was there arranging his goods regardless of explorations
in strange lands, but walked on, talking to the air, his out-thrust lips
rounding every word, until some derisive savage pointed out this
solo.
Jacques le Ber made ready to take his place in the governor’s
council, thinking wrathfully of his encounter with Tonty. He dwelt, as
we all do, upon the affronts and hindrances of the present, rather
than on his prospect of founding a strong and worthy family in the
colony.
IV.
A COUNCIL.
The North American savage, with an unerring instinct which
republics might well study, sent his wisest men to the front to
represent him.
A great circle of Indians, ranged according to their tribes, sat around
Frontenac when the stone windmill trod its noon shadow underfoot.
Te Deum had been sung in the chapel, and thanks offered for his
safe arrival. The principal men of Montreal, with the governor’s white
and gold officers, sat now within the circle behind his chair.
But Frontenac faced every individual of his Indian children, moving
before them, their natural leader, as he made his address of
greeting, admonition, and approval, through Du Lhut as interpreter.
The old courtier loved Indians. They appealed to that same element
in him which the coureurs de bois knew how to reach. The
Frenchman has a wild strain of blood. He takes kindly and easily to
the woods. He makes himself an appropriate and even graceful
figure against any wilderness background, and goes straight to
Nature’s heart, carrying all the refinements of civilization with him.
The smoke of the peace pipe went up hour after hour. By strictest
rules of precedence each red orator rose in his turn and spoke his
tribe’s reply to Onontio.[4] An Indian never hurried eloquence. The
sun might tip toward Mount Royal, and the steam of his own
deferred feast reach his nose in delicious suggestion. He had to raise
the breeze of prosperity, to clear the sun, to wipe away tears for
friends slain during past misunderstandings with Onontio’s other
children, and to open the path of peace between their lodges and
the lodges of his tribe. Ottawa, Huron, Cree, Nipissing, Ojibwa, or
Pottawatamie, it was necessary for him to bury the hatchet in
pantomime, to build a great council-fire whose smoke should rise to
heaven in view of all the nations, and gather the tribes of the lakes
in one family council with the French around this fire forever.
“Each red orator rose in his turn and spoke his tribe’s
reply.”—Page 40.
Children played along the river’s brink, and squaws kept fire under
the kettles. A few men guarded the booths along the palisades from
pilferers, though scarce a possible pilferer roamed from the centre of
interest.
Crowds of spectators pressed around the great circle; traders who
had brought packs of skins skilfully intercepted by them at some
station above Montreal; interpreters, hired by merchants to serve
them during the fair; coureurs de bois stretching up their neck
sinews until these knotted with intense and prolonged effort. In this
standing wall the habitant was crowded by converted Iroquois from
the Mountain mission, who, having learned their rights as Christians,
yielded no inch of room.
The sun descended out of sight behind Mount Royal, though his
presence lingered with sky and river in abundant crimsons. Still the
smoke of the peace pipe rose above the council ring, and eloquence
rolled its periods on. That misty scarf around the horizon, which high
noon drove out of sight, floated into view again, becoming denser
and denser. The pipings of out-door insects came sharpened through
twilight, and all the camp-fires were deepening their hue, before a
solemn uprising of Frenchmen and Indians proclaimed the council
over.
La Salle had sat through it at the governor’s right hand, watching
those bronze faces and restless eyes with sympathy as great as
Frontenac’s. He, also, was a lord of the wilderness. He could more
easily open his shy nature to such red brethren and eloquently
command, denounce, or persuade them, than stand before dames
and speak one word,—which he was forced to attempt when candles
were lighted in the candelabra of the fort.
There was not such pageantry at Montreal as in the more courtly
society of Quebec. The appearance of the governor with his train of
young nobles drew out those gentler inhabitants who took no part in
the bartering of the beaver fair.
Perrot, the sub-governor, had known his period of bitter
disagreement with Frontenac. Having made peace with a superior he
once defied, he was anxious to pay Frontenac every honor, and the
two governors were united in their policy of amusing and keeping
busy so varied an assemblage as that which thronged the beaver
fair. Festivity as grand as colonial circumstances permitted was
therefore held in the governor’s apartments. The guarded fortress
gates stood open; torches burned within the walls, and blanketed
savages stalked in and out.
Yet that colonial drawing-room lacked the rude elements which go to
making most pioneer societies. Human intercourse in frontier towns
exposed to danger and hardship, though it may be hearty and
innocent, is rarely graceful.
But here was a small Versailles transplanted to the wilderness.
Fragments of a great court met Indian-wedded nobles and women
with generations of good ancestors behind them. Here were even
the fashions of the times in gowns, and the youths of Louis’ salon
bowed and paid compliments to powdered locks. These French
colonial nobles were poor; but with pioneer instinct they decorated
themselves with the best garments their scanty money would buy.
Here thronged Dumays, Le Moynes, Mousniers, Desroches, Fleurys,
Baudrys, Migeons, Vigers, Gautiers, all chattering and animated.
Here stood the Baroness de Saint-Castin like a statue of bronze.
Here were those illustrious Le Moynes, father and sons, whose
deeds may be traced in our day from the St. Lawrence to the Gulf of
Mexico. Here Frontenac, with the graciously winning manner which
belonged to his pleasant hours, drew to himself and soothed
disaffected magnates of his colonial kingdom.
All these figures, and the spectacles swarming around the beaver
fair, like combinations in a kaleidoscope to be seen once and seen no
more, gave Tonty such condensed knowledge of the New World as
no ordinary days could offer.
La Salle alone, though fresh from audiences at court and
distinguished by royal favor, stood abashed and annoyed by the part
he must play toward civilized people.
“Look at the Sieur de la Salle,” observed Du Lhut to Tonty. “There is
a man who stands and fights off the approach of every other
creature.”
“There never was a man better formed for friendship,” retorted
Tonty. “Touching his reserve, I call that no blemish, though he has
said of it himself, it is a defect he can never be rid of as long as he
lives, and often it spites him against himself.”
La Salle turned his shoulder on these associates, uneasily conscious
that his weakness was observed, and put many moving figures
between himself and them. He had the free gait of a woodsman
tempered by the air of a courtier. More than one Montreal girl
accusing gold-embroidered young soldiers of finding the Quebec
women charming, turned her eyes to follow La Salle. Possible lord of
the vast and unknown west, in the flower of his years, he was next
to Frontenac the most considerable figure in the colony.
Severe study in early youth and ambition in early manhood had
crowded the lover out of La Salle. His practical gaze was oppressed
by so many dames. It dwelt upon the floor, until, travelling
accidentally to a corner, it rose and encountered Jacques le Ber’s
daughter sitting beside her mother.
V.
SAINTE JEANNE.
When La Salle was seignior of Lachine, before the king and
Frontenac helped his ambition to its present foothold, he had been
in the habit of stopping at Jacques le Ber’s house when he came to
Montreal.
The first day of the beaver fair greatly tasked Madame le Ber. She
sat drowsily beside the eldest child of her large absent flock, and
was not displeased to have her husband’s distinguished enemy
approach Jeanne.
The wife of Le Ber had been called madame since her husband
bought his patent of nobility; but she held no strict right to the title,
even wives of the lesser nobles being then addressed as
demoiselles. In that simple colonial life Jacques le Ber, or his wife in
his absence, served goods to customers over his own counter.
Madame le Ber was an excellent woman, who said her prayers and
approached the sacraments at proper seasons. She had abundant
flesh covered with dark red skin, and she often pondered why a
spirit of a daughter with passionate longings after heaven had been
sent to her. If Sieur de la Salle could draw the child’s mind from
extreme devotion, her husband must feel indebted to him.
La Salle’s face relaxed and softened as he sat down beside this
sixteen-year-old maid in her colonial gown. She held her crucifix in
her hands, and waited for him to talk. Jeanne made melody of his
silences. As a child she had never rubbed against him for caresses,
but looked into his eyes with sincere meditation. Having no idea of
the explorer’s aim, Jeanne le Ber was yet in harmony with him
across their separating years. She also could stake her life on one
supreme idea. La Salle was formed to subdue the wilderness; she
was dimly and ignorantly, but with her childish might, undertaking
that stranger region, the human soul. She looked younger than other
girls of her age; yet La Salle was moved to say, using the name he
had given her,—
“You have changed much since last year, Sainte Jeanne.”
“Am I worse, Sieur de la Salle?” she anxiously inquired.
“No. Better. Except I fear you have prayed yourself to a greater
distance from me.”
“I name you in my prayers, Sieur de la Salle. Ever since my father
ceased to be your friend I have asked to have your haughty spirit
humbled.”
La Salle laughed.
“If you name me at all, Sainte Jeanne, pray rather for the humbling
of my enemies.”
“No, Sieur de la Salle. You need your enemies. I could ill do without
mine.”
“Who could be an enemy to thee?”
“There are many enemies of my soul. One is my great, my very
great love.”
La Salle’s face whitened and flushed. He cast a quick glance upon
the dozing matron, the backs of people whose conversation buzzed
about his ears, and returned to Jeanne’s childlike white eyelids and
crucifix-folding hands.
“Whom do you love, Sainte Jeanne?”
“I love my father so much, and my mother; and the children are too
dear to me. Sometimes when I rise in the night to pray, and think of
living apart from my dear father, the cold sweat stands on my
forehead. Too many dear people throng between the soul and
heaven. Even you, Sieur de la Salle,—I have to pray against
thoughts of you.”
