Spectacular map of Montana, based on DeLacy's own seminal 1865 map, which was on a smaller scale. The first edition of the Colton map appeared in 1870 and was followed by editions in 1871, 1873, 1874, 1878, 1879. The bright colors are coded to distinguish Military Reservations and different types of mines. At upper right are "Sources of Information"; the authorities listed are: 1. Stevens Surveys for the N. Pacific R.Road 1853-4-5. 2. Mullans Surveys, 1859-60-61-62. 3. Raynolds Surveys on the Yellowstone & Missouri Rivers. 4. U.S. Public Land Surveys. 5. Personal Surveys & Exploration from 1859 to 1869. 6. Capt. Clift, U.S.A. Survey of route to Musselshell 1869. 7. Exploration of Messrs. Cook & Folson to the Yellowstone Lake 1869. 8.

Saunders, "W.W. deLacy's 1865 Map of the Territory of Montana" in Imago Mundi, Vol 54, 2002, pp 129-134. Gives the history of the first issues of deLacy's map. The first was by Hutawa in St. Louis; the second issue by Rae Smith in New York in two versions. Evidently, Granville Stuart's book did not include deLacy's map.
