Theodore Roosevelt Jr., (1858-1919), 26th president of the United States, from 1901 to 1909, was also a conservationist, naturalist, and writer. From 1884 to 1886, he established his ranch in Dakota Territory, which involved much hardship and toil. Ranch Life and the Hunting Trail - published in 1888 - is the account of his labors and adventures as a cowboy, hunter, herder, and even a stint as a deputy sheriff. The narrative comes alive with engaging descriptions of the inhabitants of the Badlands: the buffalo hunters, Indians, cowboys, and mountain men, as well as the changing environment as the area became more populated in that period.
