Much has been said lately of establishing steam communication with Sydney. A committee of Sydney merchants has been appointed in London to consider the subject, and the restless and indefatigable Lieut. Waghorn has written a pamphlet showing how it may be done, provided the Government will contribute 100,000 pounds per annum towards the project. He proposes that a branch line of steamers shall be established, to proceed from Sincapore by the north of New Holland, touching at Port Essington, and through Torres Straits to Sydney, and probably on to Van Dieman's Land. But why follow such a route as this, through the most dangerous channel in the world, where even steamers would have to lie-to at night (as the Lieutenant admits), and where light-houses would have to be erected and kept up at an extravagant cost? Why take such a route, which presents not a single place to call at, except Port Essington, a miserable spot, intended only as a kind of refuge for shipwrecked mariners, possessing no commercial or agricultural inhabitants, and only enjoying the advantages and the society of a Governor, a handful of soldiers, and three white women? Why insist upon expending so much public money, and encountering so many dangers, without conferring a single additional benefit upon the Australian colonies, when the route by the south of New Holland is so obvious, so practicable, and so superior? The projectors talk of making Port Essington a depot for coal; but why not make this depot in Western Australia? During the summer months, from 1st October to 1st April, the steamers might touch at Fremantle; and during the winter months, at Port Gladstone, fifteen miles to the southward, affording a sheltered harbour where ships may ride securely within one hundred yards of the shore. Coal mines will probably soon be at work in the colony, vast beds of that mineral having been discovered, thus offering every inducement to steam-vessels to touch here. Nor could anything be more advantageous, considering the great interests that England now has at stake in these seas, than to form a general depot in this colony, where her Majesty's steamers and ships-of-war might refit on occasion. As there is no other spot in all New Holland, Van Dieman's Land, or New Zealand, where first-rate ship-timber may be obtained, and where IRON, COAL, and COPPER, are also procurable in abundance, this colony offers advantages for the formation of a Government Dock-yard and depot (at Port Gladstone), that must be acknowledged by every unprejudiced person.

Objections may be raised to doubling Cape Lewin during the winter season; but let the steamers stand well out to sea, and there would be no difficulty. The time lost would not exceed that spent in lying-to in Torres Straits during the night. Our colonial schooner, the Champion, goes round Cape Lewin at all seasons.

We would propose that the mail steamers, instead of branching off from Sincapore, as proposed by Lieut. Waghorn, should depart from Point de Galle, Ceylon, make direct for Swan River, there take in coal, and pass on to Adelaide, South Australia, and thence to Van Dieman's Land, where they might put the Melbourne and Sydney mails on board of the steamer already plying between Van Dieman's Land and those places. By this route the Sydney people would receive their letters quite as soon as though their interests alone had been consulted, according to the desire of the disinterested committee before alluded to; whilst Van Dieman's Land would gain a few days, and South Australia and Western Australia would be allowed to share in the general advantage, from which they would otherwise be entirely excluded.

But the Government and the public would also be gainers by the route which we suggest. It would be much cheaper to them, because it would be much more profitable to the company that carried it out. The colony of South Australia is now a populous country, and becomes more so every year; but the Steam Company would carry no passengers and no goods for South Australia (perhaps not even for Van Dieman's Land), if the route to Sydney were to be by Port Essington and Torres Straits. The two colonies of South and Western Australia deriving no benefit from such a course, could give no support to the company. Government hitherto has resisted the efforts of the Sydney merchants, and refused to sanction the proposal of Mr. Waghorn, but chiefly upon the ground of expense. And there is no doubt that Ministers would be guilty of a gross misdemeanour, were they to consent to apply 100,000 pounds per annum of the public money in furtherance of a scheme designed for the exclusive benefit of a single colony. It is the duty of Government to see that any sum which may be granted shall be so applied as to confer the most extensive benefit upon all the Australian colonies. That measures ought to be immediately taken to ensure a regular communication between the home country and every one of her colonies is a matter of no doubt to us. The want of this has long appeared to be one of the grand errors of colonial legislation. Let us hope that the day is not far distant when this crying evil shall be remedied. Now that steam navigation has come so generally into use, there is no valid reason why it should not be made the means of uniting together, as it were, the different outposts of the empire, drawing them more closely towards their parent country as to a common centre. It is full time that a greater appearance of sympathy were exhibited at home for those distant settlements which have now become the principal markets for British produce, and which, therefore, deserve something more at the hand of Government than what they have so long been accustomed to find—alternate periods of tyranny and neglect.

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.

On Friday, the 10th April they made the coast of New Guinea, which presented a low and thickly-wooded coast-line, backed by mountains of magnificent height and beauty; the country being apparently very rich, with many villages, embowered in cocoa-nut trees, scattered along the shore. While coasting along, in search of a convenient place to land, they encountered a native vessel of most extraordinary size and character, which we will allow Mr. Yule to describe in his own words:—
