Their ignorance in building, is very amply compensated by the kindness of nature in the remarkable softness of the rocks, which encompass the sea coast, as well as those in the interior parts of the country: they are a soft, crumbly, sandy stone; those parts, which are most exposed to, and receive the most severity of the weather, are generally harder than such parts as are less exposed; in the soft parts time makes wonderful changes; they are constantly crumbling away underneath the harder and more solid part, and this continual decay leaves caves of considerable dimensions: some I have seen that would lodge forty or fifty people, and, in a case of necessity, we should think ourselves not badly lodged for a night. Wherever you see rocks in this country, either on the sea-shore, or in the interior parts, as they are all of this soft sandy kind, you are sure of finding plenty of such caves. In the woods, where the country is not very rocky, we sometimes met with a piece of the bark of a tree, bent in the middle, and set upon the ends*, with a piece set up against that end on which the wind blows. This hut serves them for a habitation, and will contain a whole family; for, when the weather is cold, which is frequently the case in winter, they find it necessary to lie very close for the benefit of that warmth to which each mutually contributes a share. These bark huts, (if they deserve even the name of huts) are intended, as we have lately discovered, for those who are employed in hunting the kangaroo, opossums, or in short, any other animals which are to be found in the woods; for at certain seasons, when those animals are in plenty, they employ themselves frequently in catching them. [* For an exact description and representation of this hut, see Governor Phillip's Voyage.] As most of the large trees are hollow, by being rotten in the heart, the opossum, kangaroo rat, squirrel, and various other animals which inhabit the woods, when they are pursued, commonly run into the hollow of a tree: in order, therefore, to make sure of them, which they seldom fail in, when they find them in the tree, one man climbs even the tallest tree with much ease, by means of notches at convenient distances, that are made with a stone hatchet; when he is arrived at the top, or where there may be an outlet for the animal, he sits there with a club or stick in his hand, while another person below applies a fire to the lower opening, and fills the hollow of the tree with smoak; this obliges the animal to attempt to make its escape, either upwards or downwards, but whichever way it goes, it is almost certain of death, for they very seldom escape. In this manner they employ themselves, and get a livelihood in the woods.
