|Summary:||Charles L. Marshall (1882-1957) was a mining engineer and surveyor. He was born in Portland, Oregon and educated at the University of Oregon, graduating in 1911 or 1912. The papers include a diary, Jan. 1907 to June 1908, describing Marshall's labors in the R and S gold mine, Curry County, Ore. The second volume of the diary has 10 pages of "Mining stories," folklore of southern Oregon and northern California mines. There are two account books showing receipts and expenses at the R and S mine, 1906-1908, and of Marshall's years at the University of Oregon, 1908-1911. From July to December 1918 he was an enlisted man in the U. S. Army, stationed at Washington Barracks, D.C. There are 41 letters, Marshall to his mother, describing his experience in Co. E, 1st Replacement Regt. Engineers. The photograph portion of the collection consists of three albums of photographs black and white prints, real photo postcards, a few commercial postcards, and 17 glass plate negatives. The dates for almost all of the images are from around 1905-1915, with the largest concentration from 1911-1912. The photographs cover mining operations in Southern Oregon, including the Bohemia mines, Lucky Boy mine, Treasure Mine, Crystal Mine, and the Champion (or Champiom) Mine. Also included are images of bridge construction in the Portland area, construction of the Walterville power plant, and Eugene's Municipal Power plant. There are also prints from several trips taken in Oregon and the Northwest, as well as postcards from a trip to South America by a friend. Several real photo postcards of the University of Oregon campus from 1911 are in the collection, a few of which are included in the 1913 Oregana. There are pictures of the buildings as well as of construction of the tennis courts and photographs from a track meet.
