Charles Edwin Kellogg’s North Dakota soil profiles, 1931

Series V consists of research files Kellogg compiled to document the history of the United States Department of Agriculture Soil Survey. Kellogg organized the file into subtopics which cover the Soil Survey's history, organization, staff, and major events. The series is therefore arranged into ten subseries in accordance with Kellogg's key, which is found at the beginning of the series. Materials are arranged in rough chronological order within each of the ten subseries
