Among the ordinary herbivorous mammals there are several which should be domesticable which have not yet been properly subjected to experiment looking to that end. The American bison, commonly but improperly termed the buffalo, is a strong creature, one which is easily nourished. In its present condition, it is about as promising a subject for the breeder's care as were the ancestors of our horned cattle. Although there have been sundry trials of this animal as a beast of burthen, they have been of a rude as well as a brief kind, no care having been taken by selection to improve the qualities which evidently commend themselves to our use. The flesh of this species is quite as good as that of the wild bulls of the genus Bos, and the hides have a peculiar value on account of their somewhat woolly character. There is reason to believe that, bred in the region of the high north, about Lake Saskatchewan for instance, with proper selection this hairy covering could be developed much as has the wool on the sheep. This is indicated by the considerable variations in the quality of the coat which go to show that the feature is still in a very plastic state, a state that may be said to invite the assistance of man in order to bring it to the full measure of its possibilities. If this covering could be developed, the result would be to give us a domesticated beast of large size with a hairy covering having the character of a fur; such would be a great addition to our resources. As there is a large extent of country in the high latitudes of North America, Asia, and South America, where the climate is too severe and the herbage too scanty to serve the needs of our ordinary cattle, in which a hardy feeder with a well-clad body such as the buffalo might do well, it seems most desirable to essay the experiment of domesticating the bison before it is too late, before the brutal instincts of our kind have quite made an end of the noblest animal which is native in the Americas. There is another inhabitant of the high north of this continent which deserves the notice of those who are disposed to attend to the questions concerning the extension of man's control over nature; this is the ovibos or musk-ox. Like the buffalo, only in much higher measure, this singular creature is fit for very cold countries; his fitness being in part assured by his admirable covering of long hair as well as by his capacity for taking on fat during the short summer in sufficient store to last him through the trials of the winter season. The kinship of the musk-ox to the group of the sheep is near enough to warrant the belief that the hair could be improved by selection, and that from the process we would be likely to obtain an animal much larger than our largest sheep and yielding fleeces of peculiar value in the arts.
