I have known a party of Sioux to steal the horses of a buffalo-hunting outfit, whereupon the latter retaliated by stealing the horses of a party of harmless Grosventres; and I knew a party of Cheyennes, whose horses had been taken by white thieves, to, in revenge, assail a camp of perfectly orderly cowboys.

Most of the ranchmen along the Little Missouri in 1884, were pretty good fellows, who would not wrong Indians, yet they tolerated for a long time the presence of men who did not scruple to boast that they stole horses from the latter; while our peaceful neighbors, the Grosventres, likewise permitted two notorious red-skinned horse thieves to use their reservation as a harbor of refuge, and a starting-point from which to make forays against the cattlemen.

The expression "too horrible to mention" is to be taken literally, not figuratively.

It applies equally to the fate that has befallen every white man or woman who has fallen into the power of hostile plains Indians during the last ten or fifteen years.

The nature of the wild Indian has not changed.
