HIRAM MARTIN CHITTENDEN, "The American Fur Trade of the Far West," 1902. The work of a distinguished Army officer. Done with the exact care of an Army engineer. An extraordinary collection of facts and a general view of the picturesque early industry of the fur trade, which did so much toward developing the American West. See also his "History of Steamboat Navigation on the Missouri River" (1903). A. J. SOWELL, "Early Settlers and Indian Fighters of Southwest Texas," 1900. A local book, but done with contemporary accuracy by a man who also studied the Texas Rangers and who was familiar with some of the earlier frontier characters of the Southwest. The foregoing volumes are of course but a few among the many scores or hundreds which will have been read avidly by every man concerned with frontier life or with the expansion of the American people to the West. Space lacks for a fuller list, but the foregoing readings will serve to put upon the trail of wider information any one interested in these and kindred themes. Let especial stress again be laid upon the preeminent value of books done by contemporaries, men who wrote, upon the ground, of things which they actually saw and actually understood. It is not always, or perhaps often, that these contemporary books achieve the place which they ought to have and hold. Among the many books dealing with the Indians and Indian Wars, the following may be mentioned: J. P. DUNN, "Massacres of the Mountains, A History of the Indian Wars of the Far West," 1886. L. E. TEXTOR, "Official Relations between the United States and the Sioux Indians," 1896. G. W. MANYPENNY, "Our Indian Wards," 1880. There is an extensive bibliography appended to Frederic L. Paxson's "The Last American Frontier" (1910), the first book to bring together the many aspects of the Far West.
