Prof. L.V. Pirsson, of Yale University, who has spent a number of years in studying the geology of various portions of the northern Rocky Mountains, wrote me with considerable fullness in 1896 concerning the game situation in some of the front ranges of the Rockies, where sheep were formerly very abundant. In the Crazy Mountains he says he saw no sheep, and that while it was possible they might be there, they must certainly be rare. In 1880 there were many sheep there. In the Castle Mountains none were seen, nor reported, nor any traces seen. The same is true of the Little Belt, Highwood, and Judith Mountains. He understood that sheep were still present in the bad lands; immediately about the mountains and east of them the country was too well settled for any game to live. Earlier, however, in the summer of 1890, passing through the Snowy Mountains, which lie north of the National Park, sheep were seen on two occasions; a band of ten ewes and lambs on Sheep Mountain, and a band of seven rams on the head of the stream known as the Buffalo Fork of the Lamar River. In 1893 an old ram was killed on Black Butte, at the extreme eastern end of the Judith Mountains, near Cone Butte, and it is quite possible that this animal had strayed out of the bad lands on the lower Musselshell, or on the Missouri. Even at that time there were said to be no sheep on the Little Rockies, Bearpaws, or Sweetgrass Hills. All the ranges spoken of were formerly great sheep ranges, and on all of them, many years ago, I saw sheep in considerable numbers. There are a very few sheep in the Wolf Mountains of Montana. There are still mountain sheep among the rough bad lands on both sides of the Missouri River, between the mouth of the Musselshell and the mouth of Big Dry. It is hard to estimate the number of these sheep, but there must be many hundreds of them, and perhaps thousands. As recently as August, 1900, Mr. S.C. Leady, a ranchman in this region, advised me that he counted in one bunch, coming to water, forty-nine sheep. Mr. Leady further advised me that in his country, owing to the sparse settlement, the game laws are not at all regarded, and sheep are hunted at all times of the year. The settlers themselves advocate the protection of the game, but there is really no one to enforce the laws. Recent advices from this country show that the conditions there are now somewhat improved. It is probable that in suitable localities in the Missouri River bad lands sheep are still found in some numbers all the way from the mouth of the Little Missouri to the mouth of the Judith River.
