ABORIGINAL INHABITANTS--THE RED MEN OF THE WILDS. While the white men from Europe occupy the whole eastern coast, pressing rapidly and steadily westward, the Redskin aborigines maintain a precarious existence throughout the centre of the continent, from north to south, and are still found here and there on the western shores. On the northern ice-bound coast, the skin-clothed Esquimaux wander in small bands from Behring Strait to Baffin Bay, but never venture far inland, being kept in check by their hereditary enemies, the Athabascas, the most northern of the red-skinned nations. The Esquimaux, inhabiting the Arctic regions, may more properly be described in the volume devoted to that part of the globe. INDIAN WIGWAMS. Here and there, in openings in the primeval forest, either natural or artificial, on the banks of streams and lakes, several small conical structures may be seen, composed of long stakes, stuck in the ground in circular form, and fastened at the top. The walls consist of large sheets of birch-bark, layer above layer, fastened to the stakes. On the lee-side is left a small opening for ingress and egress, which can be closed by a sheet of bark, or the skin of a wild animal. At the apex, also, an aperture is allowed to remain for the escape of the smoke from the fire which burns within. Lines are secured to the stakes within, on which various articles are suspended; while round the interior mats or skins are spread to serve as couches, the centre being left free for the fire. In front, forked stakes support horizontal poles, on which fish or skins are hung to dry; and against others, sheets of bark are placed on the weather-side, forming lean-tos, shelters to larger fires, used for more extensive culinary operations than can be carried on within the hut. On the shores are seen drawn up beautifully-formed canoes of birch-bark of various sizes--some sufficient to carry eight or ten men; and others, in which only one or two people can sit.
