Epilogue
Last Paragraph:
“New England is a place where human
activities are so thoroughly blended
into the otherwise natural landscape
that the distinction between them is
moot and meaningless.”
Epilogue
FINAL SENTENCE:
“To strip-mine stone walls from such a
landscape thoughtlessly, to sell them
as if they were so much blast rubble is
to unravel the binding threads that
hold our patchwork landscape of
culture and nature together. “
