The Plains were marvelously adapted to the needs of uncivilized people, who derived their sustenance from the bounty of the wilderness and to the heavy increase and perpetuation of the animal life upon which they subsisted. Upon its level floors, enemies or game could be seen from afar, an advantage in both warfare and hunting. The natural grasses were almost miraculously disposed to the peculiarities of soil and climate, affording the richest pasturage in the green of summer and becoming even more nutritious as the seasons advanced toward the snows of winter. This insured the presence of enormous numbers of herbivorous animals, such as the buffalo, the antelope and the deer, from which the Indian derived his principal food and fashioned his garments and his shelter. His only toil was the chase with its splendid excitement, and his only danger the onslaught of tribal enemies. The climate was healthful and invigorating. In all the world could not have been found a more delightful home for primitive men. That the Indian should have resisted with relentless and increasing ferocity every effort to drive him from this paradise was natural and justifiable from his point of view. In those days, he felt that to go elsewhere meant starvation and death for his family and tribe. Above all, he firmly believed that the country was his, as it had been from the beginning, and that the white man was cruel, merciless and wrong in depriving him of his old home--a home that the white man did not need and would not use. North and south across this gigantic stage the teeming animal life of the Plains, especially the buffaloes moved regularly with the procession of the equinoxes. The first grass of spring to which the Cheyennes gave the poetic name, _mah-nah-see-tah_--had scarcely made green the landscape before it was darkened with moving herds northward bound, in obedience to the primal instinct that pulses more deeply with the coming of spring. The pastures were endless, and the moist earth vibrant with the sounds of the fresh season. Everywhere wild flowers were springing from the sod. The water-holes were full, and the sandy rivers flashing in the sunshine. Clouds of water-fowl swirled and descended upon the bars, to rest in their flight to their nesting grounds. The eagle in the sky and the lark in the grass were alike free to raise their young, far from the intrusion of man. The Indians, with their women, children, dogs and ponies, moving dimly on the far-off Plains, were native to the scene, and passed unnoticed by the other denizens of the solitude.
