Old plainsmen and the Indians aver that the buffalo never return south; that each year's herd was composed of animals which had never made the journey before, and would never make it again. All admit the northern migration, that being too pronounced for any one to dispute, but refuse to admit the southern migration. Thousands of young calves were caught and killed every spring that were produced during this migration, and accompanied the herd northward; but because the buffalo did not return south in one vast body as they went north, it was stoutly maintained that they did not go south at all. The plainsman could give no reasonable hypothesis of his "No-return theory" on which to base the origin of the vast herds which yearly made their march northward. The Indian was, however, equal to the occasion. Every plains Indian firmly believed that the buffalo were produced in countless numbers in a country under ground; that every spring the surplus swarmed, like bees from a hive, out of the immense cave-like opening in the region of the great Llano Estacado, or Staked Plain of Texas. In 1879 Stone Calf, a celebrated chief, assured me that he knew exactly where the caves were, though he had never seen them; that the good God had provided this means for the constant supply of food for the Indian, and however recklessly the white men might slaughter, they could never exterminate them. When last I saw him, the old man was beginning to waver in this belief, and feared that the "Bad God" had shut the entrances, and that his tribe must starve. The old trappers and plainsmen themselves, even as early as the beginning of the Santa Fe trade, noticed the gradual disappearance of the buffalo, while they still existed in countless numbers. One veteran French Canadian, an employee of the American Fur Company, way back in the early '30's, used to mourn thus: "Mais, sacre! les Amarican, dey go to de Missouri frontier, de buffalo he ron to de montaigne; de trappaire wid his fusil, he follow to de Bayou Salade, he ron again. Dans les Montaignes Espagnol, bang! bang! toute la journee, toute la journee, go de sacre voleurs. De bison he leave, parceque les fusils scare im vara moche, ici la de sem-sacre!" CHAPTER XIII.
