We were happy to find that the attention of the public, and the Government at home, had been drawn to the wrongs and sufferings of the Aborigines of Australia; and that a desire of preserving them from deterioration and ultimate destruction, had been evinced. Protectors had been sent out for the purpose of attending especially to their interests, so that it was evident that what was wanted was not goodwill towards them. It was easy, however, to perceive that the system was a bad one, and to foretell its failure. The most prominent feature in the plan adopted, was the gathering together of the natives in the neighbourhood of settlers without previously providing them with any means of subsistence, so that they were in a manner compelled to have recourse to depredations. AMERICAN WHALERS. To show to what extent whaling is carried on in these seas by foreigners, I may mention that during our stay at Swan River, I at one time counted as many as thirteen American whalers at anchor. It was to be regretted that this department of industry had been abandoned by the colonists, who however derived considerable advantage from the barter trade they carried on with the whale ships. At Perth we found our old shipmate Miago, and were sorry to observe that he was as great a savage as ever. He had got into considerable disgrace among his fellows on account of his having performed one of these feats of which he was so continually boasting on the North-west coast, namely, carrying away a woman. He was hiding about, in momentary fear of being speared by those whom he had injured. BOTANY OF WESTERN AUSTRALIA.
