Some six years ago I asked Mr. H. Y. L. Brown, who was then engaged in making a geological survey of part of the Colony of West Australia, to procure for me some of the weapons of the natives of the west and northwest coast of Australia; and he was good enough to send me a very valuable collection, which I have used in preparing this brief account of some of the more important implements employed by the blacks in this part of the continent. In order that accurate descriptions of them might be given, I applied to the Honorable Fred. Barlee, the Colonial Secretary at Perth, to supply information respecting some of them; and with his usual kindness, and with an alacrity in the promotion of scientific investigations not always found in gentlemen occupying similar exalted positions, he furnished valuable notes, made by himself, from statements communicated to him by an intelligent native.

No one but a person who has engaged in such labors as have occupied me for many years knows how difficult it is to ascertain the facts respecting even the commoner implements and utensils used by the natives. I have had the most positive statements respecting the use of one kind of spear absolutely contradicted by other statements apparently equally trustworthy; and in all such cases it has been necessary to apply to the blacks themselves for an explanation.
