The next morning we were steering towards Mount Upstart, and at noon passed within two miles of its extremity. Behind the Mount, which rises with remarkable abruptness from the low land in its rear, are two prominent hills; the highest of which, Mount Abbott, has a peaked summit; the irregular and mountainous appearance of the range upon which this Mount stands, and a very evident break in the hills on its western side, would lead one to suspect the existence of a river, of which the bay on the western side of the Mount may be the mouth. There is also a bay on the eastern side of Mount Upstart, which also has a river-like appearance. In fact, it is not at all certain whether Mount Upstart may not be an island, and the bay behind it the mouth of a considerable stream. The variation observed by Captain Cook off Mount Upstart was 9 degrees East; but by an Azimuth observed by me close to the Cape, it was found not more than 6 degrees 16 minutes East. The result of Captain Cook's observation must therefore be attributed to some other cause than, as he supposed, to a magnetical power in the hills of this promontory.

At daylight of the 13th we passed within four miles of the extremity of Cape Bowling-green, which, although it is very low and sandy, is not destitute of wood or verdure; between Cape Bowling-green and the back mountainous ranges, a distance of nearly thirty miles, the country appears to rise gradually, and gave us reason to regret that the nature of my instructions did not warrant our making a more particular examination of this part of the coast, for it appears to offer a much greater degree of interest and importance than any part of the southward without the tropic. Indeed, this bay appeared to be equally promising in its appearance with those near Mount Upstart; and the peculiar feature of Cape Bowling-green, jutting out into the sea between them, considerably increases the probability of there being more than one or two rivers of importance hereabouts. The barren range, which has almost uninterruptedly continued from the back of Cape Palmerston, a distance of 150 miles, here ceases or retires, and leaves a gap of ten or twelve miles wide of low land; to the North-West of which, Mount Eliot, a hill of considerable height, rises rather abruptly; and, as the shores of the bay were not distinctly traced, there is fair reason for presuming that there is a river at its bottom.

The next morning we steered round Cape Cleveland and passed close to some straggling rocks on a reef that extends for four miles to the eastward of it.
Cape Cleveland is the extremity of a mountainous projection, and like Mount Upstart rises abruptly from low land, by which it is separated from the lofty range of Mount Eliot. The wooded and uneven character of the land on its west side indicated so great a likelihood of our finding fresh water that I was induced to despatch Mr. Bedwell to the shore to ascertain whether a delay might be made profitable by completing our hold with wood and water. His return bringing a favourable report, the cutter was anchored in three fathoms, at about one mile from the extremity of the Cape, bearing North 60 1/2 degrees East.
June 14 to 15.
Wooding and watering parties immediately commenced operations, which occupied them that and the following day.
June 15.
On the afternoon of the second day, I landed with Mr. Cunningham and Mr. Roe to ascend one of the hills that overlooks the bay. After two hours' climbing over huge rounded masses of granite, and penetrating through thick bushes of underwood, we arrived only at a summit considerably beneath the one we wished to reach; but as it was too late in the day to proceed further we halted; and I took a set of angles and made some memorandums for the sketch of the bay. A remarkable observation was here made upon the magnetic influence of this land; the variation was observed to be 10 degrees 32 minutes West, but on removing the compass eight yards off, it only gave 2 degrees 50 minutes East. This in some degree corresponds with Captain Cook's record of the irregularity of his compass when he passed near this part of the coast, in consequence of which he called the peaked island to the westward of the cape, Magnetical Island: this irregularity, however, was not noticed by me in my observations near the same spot; and the difference observed by him may very probably have been occasioned by the ship's local attraction, which in those days was unknown. The view obtained from this station was neither so useful nor so extensive as I had expected: the coast for six miles back is low and occupied by a large body of water; beyond which is a range of flat-topped and precipitous rocky hills that appear to be inaccessible, and to form almost an impenetrable barrier between the sea-coast and the interior. From the hazy state of the atmosphere the Palm Islands were not visible: sunset being near at hand we were obliged to hasten our descent, which, by following the course of a torrent-worn gully, proved to be much shorter and easier than, from our rugged and difficult ascent, we were led to apprehend.
