Some primitive peoples, like the Veddahs of Ceylon, had no dwellings at all, and were content with the earth and the sky; some, like the Tasmanians, slept in hollow trees; some, like the natives of New South Wales, lived in caves; others, like the Bushmen, built here and there a wind-shelter of branches, or, more rarely, drove piles into the soil and covered their tops with moss and twigs.
