should fear for a domestic animal which habitually tried the same experiment. Footnote 3: I call particular attention to this fact concerning the white goat, as certain recent writers, including Mr. Madison Grant, have erroneously denied it. In other habits also the deer vary widely in different localities. For instance, there is an absolute contrast as regards their migratory habits between the mule-deer which live in the Bad Lands along the Little Missouri, and those which live in northwestern Colorado; and this difference is characteristic generally of the deer which in the summer dwell in the high mountains, as contrasted with those which bear and rear their young in the low, broken hill-country. Along the Little Missouri there was no regular or clearly defined migration of the mule-deer in a mass. Some individuals, or groups of individuals, shifted their quarters for a few miles, so that in the spring, for instance, a particular district of a few square miles, in which they had been abundant before, might be wholly without them. But there were other districts, which happened to afford at all times sufficient food and shelter, in which they were to be found the year round; and the animals did not band and migrate as the prongbucks did in the same region. In the immediate neighborhood of my ranch there were groups of high hills containing springs of water, good grass, and an abundance of cedar, ash, and all kinds of brush in which the mule-deer were permanent residents. There were big dry creeks, with well-wooded bottoms, lying among rugged hills, in which I have found whitetail and mule-deer literally within a stone’s throw of one another. I once started from two adjoining pockets in this particular creek two does, each with a fawn, one being a mule-deer and the other a whitetail. On another occasion, on an early spring afternoon, just before the fawns were born, I came upon a herd of twenty whitetails, does, and young of the preceding year, grazing greedily on the young grass; and half a mile up the creek, in an almost exactly similar locality, I came upon just such a herd of mule-deer. In each case the animals were so absorbed in the feasting, which was to make up for their winter privations, that I was able to stalk to within fifty yards, though of course I did not shoot.
