  5. 5. NP River Know how. Know now. Irrg Item of Note: “One Government experiment farm is maintained near Mitchell, Nebraska, and another near Torrington, Wyoming. Both farms are of great value to the farmers of the valley. During the past year six cooperative retail stores and one wholesale store have been in operation. A cooperative cow testing association is doing great work in improving the quality of dairy cattle. There were twelve Farm Bureau local clubs and about the same number of Boys and Girls clubs in active existence throughout the year. Farmers of the valley are also active members of the Western Nebraska Potato Growers Association which is responsible for the valuable ‘Potato Grading Law’.” Taken from “Project History Of The North Platte Project”; Nebraska-Wyoming; 1921; Volume 1; Page 11, Paragraph 25.
