Those were the days when if a man had a deer, a sheep, an antelope, or the bosse ribs of a buffalo cow on his pack or in his wagon, it did not occur to him to shoot at the game among which he rode. I have seen sheep feeding on the prairies with antelope, and in little groups by themselves in North Dakota, Montana, and Wyoming, and men whose experience extends much further back than mine—men, too, whose life was largely devoted to observing the wild animals among which they lived—unite in telling me that they were commonly found in such situations. Personally I never saw sheep among buffalo, but knowing as I do the situations that both inhabited and the ways of life of each, I am confident that sheep were often found with the buffalo, just as were antelope.
The country of northwestern Montana, where high prairie is broken now and then by steep buttes rising to a height of several hundred feet, and by little ranges of volcanic uplifts like the Sweet Grass Hills, the Bear Paw Mountains, the Little Rockies, the Judith, and many others, was a favorite locality for sheep, and so, no doubt, was the butte country of western North Dakota, South Dakota and Nebraska, this being roughly the eastern limit of the species. In general it may be said that the plains sheep preferred plateaus much like those inhabited by the mule deer, a prairie country where there were rough broken hills or buttes, to which they could retreat when disturbed. That this habit was taken advantage of to destroy them will be shown further on.
To-day, if one can climb above timber line in summer to the beautiful green alpine meadows just below the frowning snow-clad peaks in regions where sheep may still be found, his eye may yet be gladdened by the sight of a little group resting on the soft grass far from any cover that might shelter an enemy. If disturbed, the sheep get up deliberately, take a long careful look, and walking slowly toward the rocks, clamber out of harm's way. It will be labor wasted to follow them.
Such sights may be witnessed still in portions of Montana and British Columbia, Idaho, Wyoming and Colorado, where bald, rolling mountains, showing little or no rock, are frequented by the sheep, which graze over the uplands, descending at midday to the valleys to drink, and then slowly working their way up the hills again to their illimitable pastures.
Of Dall's sheep, the white Alaskan form, we are told that its favorite feeding grounds are bald hills and elevated plateaus, and although when pursued and wounded it takes to precipitous cliffs, and perhaps even to tall mountain peaks, the land of its choice appears to be not rough rocks, but rather the level or rolling upland.
The sheep formerly was a gentle, unsuspicious animal, curious and confiding rather than shy; now it is noted in many regions for its alertness, wariness, and ability to take care of itself.
Richardson, in his "Fauni-Boreali Americana," says: "Mr. Drummond informs me that in the retired part of the mountains, where hunters had seldom penetrated, he found no difficulty in approaching the Rocky Mountain sheep, which there exhibited the simplicity of character so remarkable in the domestic species; but that where they had been often fired at they were exceedingly wild, alarmed their companions on the approach of danger by a hissing noise, and scaled the rocks with a speed and agility that baffled pursuit." The mountain men of early days tell precisely the same thing of the sheep. Fifty or sixty years ago they were regarded as the gentlest and most unsuspicious animal of all the prairie, excepting, of course, the buffalo. They did not understand that the sound of a gun meant danger, and, when shot at, often merely jumped about and stared, acting much as in later times the elk and the mule deer acted.
We may take it for granted that, before the coming of the white man, the mountain sheep ranged over a very large portion of western America, from the Arctic Ocean down into Mexico. Wherever the country was adapted to them, there they were found. Absence of suitable food, and sometimes the presence of animals not agreeable to them, may have left certain areas without the sheep, but for the most part these animals no doubt existed from the eastern limit of their range clear to the Pacific. There were sheep on the plains and in the mountains; those inhabiting the plains when alarmed sought shelter in the rough bad lands that border so many rivers, or on the tall buttes that rise from the prairies, or in the small volcanic uplifts which, in the north, stretch far out eastward from the Rocky Mountains.
While some hunters believe that the wild sheep were driven from their former habitat on the plains and in the foothills by the advent of civilized man, the opinion of the best naturalists is the reverse of this. They believe that over the whole plains country, except in a few localities where they still remain, the sheep have been exterminated, and this is probably what has happened. Thus Dr. C. Hart Merriam writes me:
"I do not believe that the plains sheep have been driven to the mountains at all, but that they have been exterminated over the greater part of their former range. In other words, that the form or sub-species inhabiting the plains (auduboni) is now extinct over the greater part of its range, occurring only in the localities mentioned by you. The sheep of the mountains always lived there, and, in my opinion, has received no accession from the plains. In other words, to my mind it is not a case of changed habit, but a case of extermination over large areas. The same I believe to be true in the case of elk and many other animals."
