_The Caribou._--The neighbour of the musk-ox in the desolate solitudes of the far north, and in part ranging over the same ground, is the caribou, the American representative of the reindeer. Indeed the caribou and the reindeer have been considered as belonging to the same species by some naturalists, but recently the American division of the genus has been shown to consist of at least five species, each of which differs from the one found in Europe and Asia. Among hunters and sportsmen, two divisions have long been known, namely, the woodland caribou and the Barren Ground caribou. The former includes the larger species, or the caribou proper, as it may be termed, and the recently described species from Newfoundland and Alaska; while the latter is represented by a single species, the _Rangifer articus_. The woodland caribou is in general about twice the size of the species inhabiting the Barren Grounds, has a height of 41/2 feet at the shoulder, and weighs some 250 pounds, although the males sometimes reach a weight of 400 pounds. Its range is from Nova Scotia and Newfoundland northwestward through the subarctic forest to British Columbia and northeastern Alaska. As its popular name signifies, its home is in the forest, and although meeting the smaller form during the latter's southward migrations, it does not extend its range to the Barren Grounds. On the south, it was formerly found in northern Michigan and in southern New York, and thence eastward through Vermont, New Hampshire, and Maine. Owing to the activity with which it has been hunted, it has for the most part been crowded to the north of the St. Lawrence, and is reported to be greatly diminished in numbers even in the wilds of Labrador. It still wanders into the woods of New Hampshire and Maine, and occurs somewhat abundantly in Nova Scotia and Newfoundland. It is the caribou of Newfoundland, etc., which comes nearest the reindeer in size and in the shape of its magnificent antlers, but none of the American species has been domesticated.
