We then stretched once more over the "divide" --  the ground, generally rough or rolling, between the fork or junction of two streams, in fact, the Indian Doab-- separating the Big Blue from its tributary the Little Blue. At 6 PM we changed our fagged animals for fresh, and the land of Kansas for Nebraska, at Cottonwood Creek, a bottom where trees flourished, where the ground had been cleared for corn, and where we detected the prairie wolf watching for the poultry. The fur of our first coyote was light yellow brown, with a tinge of red, the snout long and sharp, the tail bushy and hanging, the gait like a dog's, and the manner expressive of extreme timidity; it is a far more cowardly animal than the larger white buffalo-wolf and the black wolf of the woods, which are also far from fierce. At Cottonwood Station we took "on board" two way-passengers, "lady" and "gentleman," who were drafted into the wagon containing the Judiciary.
