The John Wittwer Collection on Agriculture in Nevada (1898-1972) contains the professional papers and records of John Wittwer in his capacity as an Agricultural Extension agent for the University of Nevada from 1921 to 1954. The records are primarily annual reports containing text, photographs, newspaper clippings, and charts that provide a rich chronicle of the conditions of agriculture and ranching in southern Nevada from 1898 to 1972, with the bulk of the material dating from 1929 to 1955. These conditions span water issues, such as flood control and irrigation, to the general difficulties of sustaining agriculture and viable food production in a desert environment. The reports come from the Agricultural Experiment Stations in Clark and Lincoln counties and most contain both a statistical report and a narrative summary.
