72. On Co-Operation

Series IV consists of a scrapbook of newspaper clippings, photographs, reprints, correspondence, and other documents. The items in the scrapbook were arranged for the most part in chronological order. Before rehousing the scrapbook pages, a title or description of each item was recorded in a numerical list in order to document the original order of the scrapbook. The scrapbook pages were then separated into small groups, still maintaining the original order, and placed in archival folders.

The scrapbook begins with Cardon's reports on research from the Judith Basin Experiment Station in 1918 and ends during his tenure at the USDA Agricultural Research Administration in 1941. There are many examples of Cardon's writing, including research articles, speeches, editorials, essays, letters, poetry and personal opinion pieces. The scrapbook supplements the documents found in Series I to III.
