(*Footnote. Steam communication between Sydney and Singapore would require three vessels of six hundred tons, one of which should leave Sydney and Singapore on the 1st of each month. Their engines should be of 200 horse-power, and furnished with tubular boilers, which consume a fifth less fuel than the others; they must carry at the least 200 tons, which, at the rate of 14 tons per diem, is sufficient for fourteen days fullspeed steaming, in which time, at the rate of 7 knots an hour, 2,352 miles will have been traversed, which is about 100 miles more than the distance between Sydney and Port Essington, and about 420 miles more than between the latter place and Singapore. This clearly shows that Port Essington is, as I have before stated, the best place for a coal-depot; and that one there would suffice for the whole line of communication. As, moreover, it is necessary that such a station should have protection against the natives, it further enhances the value of the settlement at Port Essington. This depot might be economically made, from the cheapness and abundance of coals in New South Wales; and the number of ships that are constantly passing Port Essington in ballast would be glad of the freight so far. The cost of steam vessels of the size mentioned would be about 20,000 pounds, if built of wood, and 16,000 pounds, if of iron; and the annual expense of running one would be between 3,000 and 4000 pounds.) (**Footnote. On this inshore track steamers would be able to replace with wood any deficiency in their fuel. I take this opportunity of saying that vessels carrying troops from Sydney to India should be compelled to use it, the chances of the loss of life being much less. On one occasion a ship called the Ferguson sailed from Sydney with part of a regiment, whilst we were there. The master ridiculed the advice given him by one of the Beagle's officers, to take the inner passage. The next news we heard of her was, that she had been wrecked on the outer Barrier at four in the morning; no observation having been taken since the previous noon, by which they might have found a current drifting them to the northward. Fortunately, another ship was in company, and saved the loss of life, but that of property was great. The fact that the lives of so many souls should be placed at the mercy of careless masters of ships, who run such risks, in spite of the warnings of experience, deserves the serious attention of Government.)
