The Papers of Paul H. Hummel consists primarily of correspondence dated 1938-1963. There are letters from and to Forest Service personnel concerning grazing permits, changes in numbers of cattle allowed under the permits and locations for grazing on Forest Service lands. He corresponded with members of a variety of livestock associations on the local, state and national level about grazing on public lands. Hummel's involvement in the range demonstration program of the early 1950s is also reflected in the correspondence. Also included are some reports related to grazing issues and the demonstration program.
