ECONOMIC CONDITIONS. 125 The American reindeer is characterized by two particularities: its migratory habits and its gregariousness. In midsummer the cows return from the Arctic Ocean to meet the bulls in the Barren Grounds, and they are then also joined by other caravans from the westward, when their herds become simply enormous. Tyrrell and Pike, during their respective journeys to that land of desolation, saw herds of them that should have been counted by the thousand. It is at this time of the year that they fall victims to the avidity of the Deénés. But their stay is short, their passage rapid, and once gone they may not be seen again for a whole year. C. Whitney estimates the average weight of the full grown Barren Ground cariboo or reindeer bull at something between 150 and 200 pounds, whereas the woodland or common cariboo probably averages 100 pounds more. According to the same authority, the woodland cariboo (Rangifer caribou, Linn.) is much darker in colour, especially in the markings on the neck and belly, and its antlers are shorter, heavier and with larger palmations. Generally speaking, they range between the 50th and the 67th degrees of latitude on cither side of the Rocky Mountains. Though gregarious to a degree and also more or less migratory, they are never found in anything like the immense herds of their Barren Grounds cousins. In fact they seldom go more than 30 or 40 together. Within British Columbia and Alaska the mountains, generally above the timber limits, are their favourite haunts. Another and even larger kind of deer which often contributes towards the sustenance of the northern Déné is the moose (Alces americanus). Mt. James Lockhart reports having seen on Peel River and at Fort Yukon two monstrous specimens whose meat alone weighed over 1000 pounds}. These animals are not gregarious as the two species of cariboo just mentioned, and they are liable to be found anywhere within that area. Roderick Macfarlane observed tracks of some near Wilmot Horton River, in the Barren Grounds, by about latitude 69° N. and longitude 126° 30’ W.2. Nay, Sir Robert McClure saw as far north as 71° lat. three animals which he firmly believed to be moose. Of late they have become quite plentiful in the country of the western Nahanais, and correspondingly scarce east of the Rockies, especially along the Athabasca, Peace and lower Liard. The moose is economically speaking a most valuable animal to the Dénés, as the large size and thickness of its skin allow ofits being used to greater advantage in the preparation of tents or lodges, carrioles or toboggans, shirts, tunics and trousers. Some skins are also cut up for pack cords and others turned into parcliment for the manufacture of large travelling bags or used in lieu of window panes. * Proc. U. S. National Museum, vol.
