Arrived at the camp, fresh fuel was put on the smouldering fire, the embers were blown into a lively flame, and then the black fellow began operations by splitting the crook into slabs, cutting them thinner and thinner until of the required thickness. This was the first step in the making of a boomerang. The next was to put the slabs on the fire, where we watched them roasting and sizzling, for they were green and full of sap. In this state the wood is very pliable, and from time to time he took a crook off, held it between his toes, knees, and teeth, and twisted out all its inequalities. I have noticed that these people use their teeth with great dexterity.
