In the absence of facts based on personal observations, I may be permitted to advance an opinion in regard to the wood buffalo. There is some reason for the belief that certain changes of form may have taken place in the buffaloes that have taken up a permanent residence in rugged and precipitous mountain regions. Indeed, it is hardly possible to understand how such a radical change in the habitat of an animal could fail, through successive generations, to effect certain changes in the animal itself. It seems to me that the changes which would take place in a band of plains buffaloes transferred to a permanent mountain habitat can be forecast with a marked degree of certainty. The changes that take place under such conditions in cattle, swine, and goats are well known, and similar causes would certainly produce similar results in the buffalo. The scantier feed of the mountains, and the great waste of vital energy called for in procuring it, would hardly produce a larger buffalo than the plains-fed animal, who acquires an abundance of daily food of the best quality with but little effort. We should expect to see the mountain buffalo smaller in body than the plains animal, with better leg development, and particularly with stronger hind quarters. The pelvis of the plains buffalo is surprisingly small and weak for so large an animal. Beyond question, constant mountain climbing is bound to develop a maximum of useful muscle and bone and a minimum of useless fat. If the loss of mane sustained by the African lions who live in bushy localities may be taken as an index, we should expect the bison of the mountains, especially the "wood buffalo," to lose a great deal of his shaggy frontlet and mane on the bushes and trees which surrounded him. Therefore, we would naturally expect to find the hair on those parts shorter and in far less perfect condition than on the bison of the treeless prairies. By reason of the more shaded condition of his home, and the decided mitigation of the sun's fierceness, we should also expect to see his entire pelage of a darker tone. That he would acquire a degree of agility and strength unknown in his relative of the plain is reasonably certain. In the course of many centuries the change in his form might become well defined, constant, and conspicuous; but at present there is apparently not the slightest ground for considering that the "mountain buffalo" or "wood buffalo" is entitled to rank even as a variety of _Bison americanus_. Colonel Dodge has recorded some very interesting information in regard to the "mountain, or wood buffalo," which deserves to be quoted entire.[34] [Note 34: Plains of the Great West, p. 144-147.]
