William Hull Botsford’s diary for 1910. Entries mostly concern his work for the Delaware, Lackawanna, and Western Railroad, with mentions of projects in Lake Hopatcong, Bath, Bloomfield, Andover, and Towaco. Entries also discuss Botsford’s entry in the design competition for the YMCA of the Oranges in New Jersey. Enclosures in the diary include letters to Botsford from his younger siblings, Talitha and Emory, as well as photographs of Botsford and friends. Some pages are damaged by adhesives, and the diary’s spine is missing.
