This brought another laugh from Mr. Bailey.  "That doesn't worry them in the least!" he declared.  "Most bushmen are covered from head to foot with hair, and I imagine they think this is a good enough uniform, for they wear nothing except what nature gave them.  In bad weather, however, they do add some artificial protection to their tough bodies by making a rough wrap out of the skin of a kangaroo or a piece of flexible bark.  Some tribes use rushes and seaweed for this purpose, while others make a blanket from the dried frog scum of the swamps and ponds.  For boats, pieces of eucalyptus bark, folded and tied at the ends and daubed with clay, suit them very well.  They are too lazy to dig out the trunk of a tree for a canoe, like the natives of most other countries."
