More chipping, then more roasting, and the growing boomerang was now and again tossed carelessly on the ground just to see how it would act, while he glanced at it sideways, gave it a poke with his foot, and reminded me of a sedate old tom cat playing with a mouse. At last he gave it a gentle shy along the ground; then a stronger motion. It was buoyant, satisfactory. For the finishing off, it was scraped with a piece of broken bottle, the edges sharpened all around, and it was done--the boomerang was made! “White fellow, boss, chuck!” he said, handing it to me. It weighed about half a pound; the under side was rather flat, yet not entirely so, and the upper side slightly rounded, with the ends a little thinner than the centre. It was about half an inch thick and two and a half inches broad. After having amused myself while he was making another, I handed it back to him and told him to “chuck.” It proved to be a very good one, and he entertained me with it for a long time. It is held with the flat side down and the concave edge forward, and is thrown from over the shoulder. At the moment when it leaves the hand it must be in an upright or perpendicular position.
