Professor. Research notes and township maps (circa 1937) of the Cherokee Nation of Oklahoma, on which Hewes plotted the following data: which groups (categorized by degree of Indian blood, intermarried citizens, or freedmen) settled which allotments, along with the classification of these allotments and the appraised value per acre of each. Hewes used the information included on these maps to write his dissertation, “The Geography of the Cherokee Country of Oklahoma,” at the University of California in 1940. Also included are research files (1928–1998), maps (1921–1987), and correspondence relating to Hewes’s teaching and publications; research notes and data on the geography and agriculture of the Central Great Plains, irrigation, and land fencing; lecture notes from geography classes taught by Hewes and class notes taken by Hewes as a graduate student; biographical and other materials related to Hewes’s professional career and studies at the University of California at Berkeley and the University of Oklahoma; and maps, photographs, lantern slides, and color slides related to Hewes’s research.
