The manuscript collection includes four log and work books kept by surveyors probably during the construction of a short rail line with the initials A.P.R.T. Co. -- Alaska-Pacific Railway and Terminal; Company. The books mention going in and out of Juneau as well as Whale Island and Lake Kustaka; Catalla [Katalla] is also mentioned. The notes are mostly property boundary surveys and a few tonnage calculations.

According to Howard Clifford in Rails North, "The APRandT Co. was headed by Dr. M.W. Bruner and his operation was often referred to as the Bruner Road. Construction was by the Keystone Construction Co." (p. 138). Volume four contains a 6 page diary of a mining uprising in Alaska with Copper River and Northwestern Railway workers. APRandT employees dynamited a trestle and equipment owned by the Guggenheim-Morgan syndicate which owned the Copper River and Northwestern Railway Co. APRandT employees mentioned in the diary include Mike and Black Sullivan, Hampton, Sawyer, Sothers, and Pionus. In Rails North Clifford describes the "great rivalry between the two outfits." (p. 139).
