By far the greater portion of English merchant-ships are engaged in trading to the colonies; our manufactures there find their principal mart; our surplus population is there cheaply provided with maintenance and a home. These are the grounds on which the colonies lay claim to the fostering care of the Mother Country, and we trust the days are at hand that will see it afforded. The first step must be to ensure a regular and frequent intercourse between the countries, without which there can be no real protection; without which there is no sufficient encouragement given to trade; and the parent state can therefore reap but little advantage, comparatively, from a colony whose powers are only imperfectly developed. Since the above remarks were written, accounts have reached England of the arrival at Fremantle of her Majesty's surveying vessel Bramble, Commander Lieutenant Yule, after passing some time in Torres Straits and on the coast of New Guinea. Mr. Yule having kindly placed the notes of his voyage at the disposal of a friend in the colony, they were partially published in one of the local journals in the month of January last. The portion relating to Torres Straits is instructive. The Bramble sailed from Port Jackson about the end of December 1845, in company with the Castlereagh tender, Lieut. Aird, Commander. Touching at Moreton Bay, Mr. Yule visited his old acquaintance, Captain Wickham, R.N., late in command of H.M.S. Beagle, and now a settler on the Brisbane. In the words of the journal referred to, "the Bramble proceeded slowly to the northward, being much delayed by the bad sailing of the tender." The voyage presents nothing worthy of notice, until the arrival of the ships in Torres Straits, when it is impossible to help being struck with the commentary which Mr. Yule unconsciously affords upon the "perfect safety" of that passage, now so much vaunted by the advocates of the northern route. While the Bramble and Castlereagh were lying off Sir Charles Hardy's Islands, the latter being deficient in ballast, Mr. Aird was despatched with the boats to look for the "wreck" of the Maid of Athens and the "wreck" of the Martha Ridgway, with the view of procuring some; and having failed in discovering the former, and therefore in procuring a sufficient supply, he was again sent to the "wreck" of the Sir Archibald Campbell for the same purpose. So much for Torres Straits! Mr. Yule strongly recommends Cairncross Island as the best station for obtaining wood and water for vessels navigating the straits, there being abundance of both easily procurable, and even large timber, if required. On this island they shot four megapodii, and observed many of their nests, some of which Mr. Yule describes as being twelve feet high, and upwards of fifty feet in circumference.
