The part of New Guinea above alluded to, which had often afforded us the materials of interesting speculation, also formed part of the survey of Captain Blackwood, who writes as follows: "On the coast of New Guinea we found a delta of fine rivers, and a numerous population, all indicating a rich and fruitful country. It is true that we found the inhabitants very hostile; but it must be considered that we were the first Europeans that they had ever seen; and I have no doubt that, on a further acquaintance, and convinced of our power, they might be easily conciliated. Their houses, arms, and cultivation, all indicate a considerable degree of civilization, and no small intelligence in the construction of their canoes; and I think it probable that a trade might be opened with this hitherto perfectly unknown people and country."* The people inhabiting the islands fronting the coast, Captain Blackwood found to be highly inclined to trade, readily bartering a valuable species of tortoise-shell for European articles of hardware. (*Footnote. See Nautical Magazine for December 1845.) H.M.S. FAVOURITE. During our stay at Sydney we also met H.M.S. Favourite, Captain T.R. Sullivan, just returned from visiting the Eastern Polynesian Isles, having succeeded in rescuing the guns that were lost from the ship in a melancholy and much to be lamented affray with the natives of Tongataboo, previous to the command of Captain Sullivan, whose adventure in this affair was very interesting, and cleverly managed. HURRICANE. The Favourite had experienced a hurricane* off Mangaia Island, the natives of which gave notice of its approach; and at Tahiti Captain Sullivan was also told that he might expect a hurricane before long. From this, and the experience of other navigators, it appears that rotatory gales are prevalent in the Pacific as well as in the Indian Ocean.
