Century Dictionary and Cyclopedia

1. n. The wild ox of Tibet, Poëphagus grunniens, or any of its domesticated varieties; the grunting ox. The yak is a remarkable instance of the development of the pelage under climatic influences. The modification is like that seen in the musk-ox of arctic regions, Ovibos moschatus, though altitude has done for the yak what has resulted from latitude in the case of the musk-ox. The body is covered with very long hair hanging from the shoulders, sides, and hips nearly to the ground, and the tail bears a heavy brush of long hairs. The wild animal, which inhabits the mountains of Tibet about the snow-line and descends into the valleys in winter, is of a blackish color; the back is humped; and the general form is not unlike that of the bison, though the long hair gives the animal a different appearance. The actual relationships of the yak are with the humped Asiatic cattle of which the zebu is the best-known domesticated stock. The yak is of great economic importance to the Tibetans, and has been domesticated. In this state it sports in many color-variations, like other cattle. It is used as a beast of burden, makes excellent beef, and yields rich milk and butter; the long silky hair is spun and woven for many fabrics. The tails when mounted furnish the fly-snappers or chowries much used in India, and they are also dyed in various colors as decorations and ceremonial insignia. The elephant-headed god Ganesa is usually represented as flourishing the chowry with his trunk over the heads of various personages of the Hindu pantheon. Yaks have often been taken to Europe, where they are kept in menageries, and have repeatedly been bred in confinement. The yak crosses easily with some other cattle, producing various mixed breeds.
