Prior to the agreement of 1876 buffalo and deer were the main support of the Sioux. Food, tents, bedding were the direct outcome of hunting, and, with furs and pelts as articles of barter or exchange, it was easy for the Sioux to procure whatever constituted for them the necessaries, the comforts, or even the luxuries of life. Within eight years from the agreement of 1876, the buffalo had gone, and the Sioux had left to them alkali land and government rations. It is hard to overestimate the magnitude of the calamity, as they viewed it, which happened to these people by the sudden disappearance of the buffalo and the large diminution in the numbers of deer and other wild animals. Suddenly, almost without warning, they were expected at once and without previous training to settle down to the pursuits of agriculture in a land largely unfitted for such use. The freedom of the chase was to be exchanged for the idleness of the camp. The boundless range was to be abandoned for the circumscribed reservation, and abundance of plenty to be supplanted by limited and decreasing government subsistence and supplies. Under these circumstances it is not in human nature not to be discontented and restless, even turbulent and violent.1
