Scope and Content
The papers of T.H. Hopper mainly consist of records relating to his work at the NDAC Experiment Station from 1920-1939. The documents are dated from 1921-1947. The folders are arranged in a single subject file.
The collection contains documents related to Hopper's work with the Agricultural Experiment Station at NDAC. There is extensive correspondence between Hopper and other faculty members of NDAC, agricultural chemists from other areas of the country and individuals seeking information pertaining to his work in agriculture.
Hopper worked extensively with research on flaxseed and other crops. There are several papers and research reports related to this work. The Hopper papers also include reports from research of sunflowers, soybeans, safflower, cattle, and meat investigations. Some of the findings were published by Hopper and some by other faculty. There are several findings published by the United States Department of Agriculture from the 1935 census including reports of farm size, crop summaries, and number of farms per county in North Dakota.
