Book excerpt: Lt. Abert of the United States Army Topographical Engineers set out from Bent's Fort to conduct a detailed reconnaissance of the Canadian River region of the southern plains. Possessing a great eye for detail, Lt. Abert provided clear, graphic decriptions of birds, plants, animals, and the countryside, as well as details about the Comanches and the Kiowa. Lt. Abert's journal is one of the concluding records of the Anglo-American exploration of the American West begun in 1804 by Lewis and Clark.
