The Oregon State College (OSC) subseries consists of Legg's work for the college as an architect and landscape designer along with his related extracurricular activities. Employment records, along with college related clipping, pamphlets, and programs comprise the first file. The subseries also contains transcripts of Legg's one-hour gardening program, college catalogs, and Alumni News newsletters; the first has a one page article by Legg. The folders of the Oregon Society of Landscape Architect (OSLA) and the OSC Gates and Gardens Committee (GGC) contain a limited number of records from each organization. The OSLA folder includes bylaws, clippings, a membership list, and a copy of minutes from a single meeting. The GGC folder contains clippings, correspondence, fliers, and pamphlets. The OSLA and GGC files are followed by a folder of clippings primarily related to the GGC; however the folder does contain clippings related to other programs at OSC.
