The official statistics of the Commonwealth reported, in regard to the aborigines, in the year 1907: "In Queensland, South Australia, and Western Australia, on the other hand, there are considerable numbers of natives still in the 'savage' state, numerical information concerning whom is of a most unreliable nature, and can be regarded as little more than the result of mere guessing. Ethnologically interesting as is this remarkable and rapidly disappearing race, practically all that has been done to increase our knowledge of them, their laws, habits, customs, and language, has been the result of more or less spasmodic and intermittent effort on the part of enthusiasts either in private life or the public service. Strange to say, an enumeration of them has never been seriously undertaken in connection with any State census, though a record of the numbers who were in the employ of whites, or living in contiguity to the settlements of whites, has usually been made. As stated above, various guesses at the number of aboriginal natives at present in Australia have been made, and the general opinion appears to be that 150,000 may be taken as a rough approximation to the total. It is proposed to make an attempt to enumerate the aboriginal population of Australia in connection with the first Commonwealth Census to be taken in 1911." A very primitive savage was the Australian aboriginal. He had no architecture, but in cold or wet weather built little break-winds, called mia-mias. He had no weapons of steel or any other metal. His spears were tipped with the teeth of fish, the bones of animals, and with roughly sharpened flints. He had no idea of the use of the bow and arrow, but had a curious throwing-stick, which, working on the principle of a sling, would cast a missile a great distance. These were his weapons--rough spears, throwing-sticks, and clubs called nullahs, or waddys. (I am not sure that these latter are original native words. The blacks had a way of picking up white men's slang and adding it to their very limited vocabulary; thus the evil spirit is known among them as the "debbil-debbil.") Another weapon the aboriginal had, the boomerang, a curiously curved missile stick which, if it missed the object at which it was aimed, would curve back in the air and return to the feet of the thrower; thus the black did not lose his weapon. The boomerang shows an extraordinary knowledge of the effects of curves on the flight of an object; it is peculiar to the Australian natives, and proves that they had skill and cunning in some respects, though generally low in the scale of human races.
