The Chicago, Milwaukee & Puget Sound–the Pacific Coast extension of the Chicago, Milwaukee & St. Paul (which in those days was known as the St. Paul Road; the nickname changed to Milwaukee Road only after the company went bankrupt and reorganized) published this beautiful 64-page booklet in 1911. The booklet was glue-bound and my copy is fragile, so for now I’m going with a scan of the Library of Congress’ copy from Archive.org. Other than a few library markings, it is a good scan.
I also have a brochure that the Library of Congress apparently didn’t have announcing the booklet. It describes it as “the first book of the Chicago, Milwaukee and Puget Sound.” The booklet itself says it was written by someone named Isabelle Carpenter Kendall. Update: According to this obituary, Kendall (1864-1944) was a journalist who edited the Milwaukee Road’s publications for 43 years from 1897 to 1940. Her father was the Milwaukee’s general passenger agent, and her husband also worked for the railroad.
