With us the first animal to disappear was the buffalo. In the old days, say from 1870 to 1880, the buffalo were probably the most abundant of all animals along the Little Missouri in the region that I know, ranging, say, from Pretty Buttes to the Kildeer Mountains. They were migratory, and at times almost all of them might leave; but, on the whole, they were the most abundant of the game animals. In 1881 they were still almost as numerous as ever. In 1883 all were killed but a few stragglers, and the last of these stragglers that I heard of as seen in our immediate neighborhood was in 1885. The second game animal in point of abundance was the blacktail. It did not go out on the prairies, but in the broken country adjoining the river it was far more plentiful than any other kind of game. Blacktail were not much slaughtered until the buffalo began to give out, say in 1882; but by 1896 they were not a twentieth—probably not a fiftieth—as plentiful as they had been in 1882. A few are still found in out-of-the-way places, where the ground is very rough. Elk were plentiful in 1880, though never anything like as abundant as the buffalo and the blacktail. Only straggling parties or individuals have been seen since 1883. The last I shot near my ranch was in 1886; but two or three have been shot since, and a cow and calf were seen, chased and almost roped by the riders on the round-up in the fall of 1892. Whitetail were never as numerous as the other game, but they held their own better, and a few can be shot yet. In 1883 probably twenty blacktail were killed for every one whitetail; in 1896 the numbers were about equal. Antelope were plentiful in the old days, though not nearly so much so as the buffalo and blacktail. The hunters did not molest them while the buffalo and elk lasted, and they then turned their attention to the blacktail. For some years after 1883 I think the pronghorn in our neighborhood positively increased in numbers. In 1886 I thought them more plentiful than I had ever known them before. Then they decreased; after 1893 the decrease was rapid. A few still remain. Mountain sheep were never very plentiful, and decreased proportionately with less rapidity than any other game; but they are now almost exterminated. Bears likewise were never plentiful, and cougars were always scarce.
