We now come to the _American buffalo_, or _Bison_, as it should be called. This is indigenous to North America; and its present range is confined to the great prairies that extend eastward from the foot of the Rocky Mountains. It was formerly found much farther to the east--in fact, to the Atlantic coast; but its limits are now far beyond the meridian of the Mississippi. Hunters (both red and white) have driven it across the Rocky Mountains; and of late years it has been met with in the territory of the Upper Columbia. Its habits are too well-known to call for a description here, and its shaggy coat, with the deformity of its huge shoulder-hump, are familiar to every eye. With one exception, it is the only species of the ox tribe indigenous to America--and it may be added, to North America--since no native bovine animal is known to exist in the southern half of the Transatlantic continent. The _European buffalo_--or as it is sometimes called _Lithuanian buffalo_--bears a considerable resemblance to that of the prairies. In size it is perhaps superior; but the two are much alike in general appearance--especially in their massive form, and the long brown hair, of woolly texture, so thickly set upon their necks and shoulders. The European buffalo is nearly extinct, and exists only in some of the forests of Lithuanian Poland, where it is rather half-wild than wild; that is, it freely roams the forests, but only as the deer in our own extensive parks, or the white cattle, known as the wild Scotch oxen--in other words, it has an owner. A very remarkable species is the _Yak_, or _Grunting Ox_. This is found only in the high, cold countries that lie to the north of the Himalayan Mountains--in Thibet and Tartary. There is only one species, but this is both wild and tame--the wild sort being the larger and more formidable animal. The domestic variety is used by the people of Thibet for carrying burdens; and both its milk and flesh are in great demand in these cold countries of poverty and hunger. The yaks dislike the warmth of summer; and during that season seek to hide themselves in the shade, or under water, in which they swim well. Their grunt exactly resembles that of a hog. The calves are covered with rough black hair like a curly-haired dog; but, when three months old, they obtain the long hair that distinguishes the full-grown animal, and which hangs so low as to give it the appearance of being without legs! They willingly live with common cattle, and will breed with them; but the wild yak bull is an exceedingly fierce and dangerous animal. The tail of the grunting ox is very full, or bushy; and although the hair of the body is usually black, that upon the tail is universally of a pure white. This hair, when dyed red, is used by the Chinese to form the tufts worn in the caps of the mandarins. It is the _chowry_ or fly-brush of India.
