SYDNEY BAY*,
Lies in latitude 29° 05' south; longitude 168° 02' east; and variation 11° 00' east. The tide flows full, and changes at three quarters past seven, and rises from five to seven feet: the flood runs to the south-west by south; and the ebb to the north-east by north.
[* For Sydney-Bay, Norfolk Island, upon a large scale, see Phillip's Voyage.]
In general the tides are equal each way, the ebbs and the flows regular along the shore six each tide: the eastern tide is stronger than the western tide; sometimes the eastern tide runs several hours beyond its usual course, and sometimes the western tide thus irregularly, which irregularities, although they seldom happen, make it necessary to bring to, and try the tide before you come within the outer part of the Nepean Island; and be aware of an indraught, which sometimes sets into the bight on the west side of the bay, on both tides, while you are baffled by the south-east and southerly winds, as you come in with Sydney-Bay.
All within Nepean Island is foul ground, and very irregular soundings, and no safe passage between it and Point Hunter; but if a ship should be pressed by necessity, I would recommend keeping within half a cable's length of Nepean Island, after having passed the bed of rocks to the westward of the little bay.
Norfolk Island lies north-west by north and south-east by south, and is in this direction about five miles long, and nearly three in breadth; it is very thickly covered with wood, of which there are six or seven different kinds, and some I believe might be applied to naval purposes.
The Pines, which has been particularly spoken of by Captain Cook, and by others, who have lately visited this island, is the most conspicuous of any tree here; they grow to a prodigious size, and are proportionably tall, being from 150 to 200 feet, and in circumference from 12 to 14 feet, some to 28 and 30 feet. These trees, from their immense height, have a very noble appearance, being in general very straight, and free from branches, to 40, sometimes 60 feet, above the ground; they have been by some thought fit for masts, for ships of any size; in length and diameter they certainly are, but with respect to quality they are, in my opinion, wholly unfit; even admitting them to be found, which, from experience, I know is seldom the case.
I employed the carpenters of the Sirius, while here, to cut down a few sticks, which it was intended should be sent home by the first opportunity, in order for trial in his Majesty's dock-yards, to see if they were, as had been said, fit for his Majesty's navy, or not. In providing a top-mast and a top-sail-yard for a seventy-four gun ship, a thirty-two, a twenty, or a sloop, and one rough spar, in all seven sticks, 34 trees were cut down, 27 of which were found defective. When these trees were falling, it was observed that most of them discharged a considerable quantity of clear water, which continued to flow at every fresh cut of the axe; there is no turpentine in these trees but what circulates between the bark and body of the tree, and which is soluble in water. It is a very short grained and spongy kind of timber, and I think fit only for house-building, for which we know it to be very useful.
When fresh cut down, five out of six will sink in water, the wood is so exceedingly heavy: and, if we suppose for a moment, that great part of the pine timber were fit for naval purposes, the great difficulty, and indeed I may say impossibility, of getting it from the interior parts of the island to the sea, would render it of little value, if designed for masts; but if for plank, it could be cut up where fallen. Those which grow on the south-east point of the island, where the land is low, are those which have hitherto been made use of.
Norfolk Island, if correctly laid down in a plan, with all the hills and vallies represented accurately, would very much resemble the waves of the sea in a gale of wind; for it is composed wholly of long, narrow, and very steep ridges of hills, with deep gullies, which are as narrow at the bottom as the hills are on the top, so that there is scarcely any level country upon it; but as viewed from the sea, it appears quite level, the different ridges being nearly the same in height.
