Among the natives of North Australia a totally different method |26| appears to have been adopted, the flakes being struck off the stone which is used as a hammer, and not off the block which is struck. In the exploring expedition, under Mr. A. G. Gregory, in 1855–6, the party came on an open space between the cliffs along one of the tributary streams of the Victoria River, where the ground was thickly strewn with fragments of various stones and imperfectly-formed weapons. The method of formation of the weapons, according to Mr. Baines,[103] was this, “The native having chosen a pebble of agate, flint, or other suitable stone, perhaps as large as an ostrich egg, sits down before a larger block, on which he strikes it so as to detach from the end a piece, leaving a flattened base for his subsequent operations. Then, holding the pebble with its base downwards, he again strikes so as to split off a piece as thin and broad as possible, tapering upward in an oval or leaf-like form, and sharp and thin at the edges. His next object is to strike off another piece nearly similar, so close as to leave a projecting angle on the stone, as sharp, straight, and perpendicular as possible. Then, again taking the pebble carefully in his hand, he aims the decisive blow, which, if he is successful, splits off another piece with the angle running straight up its centre as a midrib, and the two edges sharp, clear, and equal, spreading slightly from the base, and again narrowing till they meet the midrib in a keen and taper point. If he has done this well, he possesses a perfect weapon, but at least three chips must have been formed in making it, and it seemed highly probable, from the number of imperfect heads that lay about, that the failures far outnumbered the successful results. In the making of tomahawks or axes, in which a darker green stone is generally used, great numbers of failures must ensue; and in these another operation seemed necessary, for we saw upon the rocks several places were they had been ground, with a great expenditure of labour, to a smooth round edge.”
