The number of the natives in these inland parts must, however, be very small. Whether these reside by choice where they must encounter so many difficulties, or whether they are driven from the society of those who inhabit the coast, has not yet been discovered. The huts seen here consisted of single pieces of bark, about eleven feet in length, and from four to six in breadth, bent in the middle while fresh from the tree, and set up so as to form an acute angle, not a little resembling cards set up by children. In the plate inserted here, not only the huts, but some of the spears of the natives are introduced. It was conjectured, that the chief use of these imperfect structures might be, to conceal them from the animals for which they must frequently be obliged to lie in wait. They may also afford shelter from a shower of rain to one or two who sit or lie under them. The bark of many trees was observed to be cut into notches, as if for the purpose of climbing; and in several there were holes, apparently the retreat of some animal, but enlarged by the natives for the purpose of catching the inhabitant. The enlargement of these holes with their imperfect instruments, must itself be a work of time, and must require no little patience. In some places, where the hole was rather too high to be reached from the ground, boughs of trees were laid to facilitate the ascent. The animals that take refuge in those places are probably the squirrel, the opossum, or the kanguroo-rat. At the bottom of one of these trees, the skin of a flying squirrel was found.
