History of the settlement of the western Canadian prairie lands, from pioneers in covered wagons to the booming wheat industry of the early 20th century. Shows that the prosperity brought by wheat built the western cities and led to rampant increases in production, when "wheat flowed like a golden river." The plowing of vast acreage without concern for soil conservation led to the disastrous collapse of the western agricultural economy. "Long years of intensive drought, coupled with a disastrous fall in prices, forced many Prairie farmers to board up their homes and seek work elsewhere. But the majority remained, hating to leave the land they had broken, often lacking the capital to make a fresh start. To these, the Prairie Farm Rehabilitation Administration, working through engineers and scientists on the experimental farms and stations, restored faith and morale. Conservation of moisture, development of new methods of farming and conversion of sub marginal land to other uses all helped to put these derelict farms once again on a working basis" (National Film Board of Canada catalog record http://onf-nfb.gc.ca/en/our-collection/?idfilm=18392).
