From this time to the 3rd November the winds continued to blow almost uninterruptedly from the south and eastward, which carried us as far west as longitude 101 degrees east, and latitude 31 degrees south, where we met with westerly winds, which enabled us to run up to within sight of Cape Naturaliste by the 8th. 9th November. By 10 a.m. we were off Rottnest Island, when the pilot came on board and took us to the anchorage in Gage's Roads by noon. Having given instructions to Mr. Turner for the landing of the horses, etc., I landed with Messrs. Brown, Harding, and Hall, all of whom were, at their desire, at once released from the duties of the Expedition. Proceeded by steamer to Perth. 10th November. Had an interview with His Excellency the Governor, and reported the safe return of the party and general results of the Expedition. F.T. GREGORY, Commander North-West Australian Expedition. Perth, 6th February, 1862. ... APPENDIX. Adopting the course which I have found most convenient on similar occasions, I now proceed to offer a few remarks on the general features, productions, and natural capabilities, etc., of the country traversed by the Expedition, which could not, without disadvantage, have been introduced into the foregoing narrative. These remarks have already appeared at the conclusion of my report published on the 18th November, 1861, but are equally applicable to the present publication. Commencing with its geographical and geological peculiarities, that portion of the country that came under our observation consists of a succession of terraces, rising inland for nearly 200 miles, more or less broken up by volcanic hills towards the coast. The first belt averages from ten to forty miles in width from the sea, and is a nearly level plain, slightly ascending to the southward, with an elevation of from 40 to 100 feet, the soil being generally either light loam or strong clays, according as it is the result of the disintegration of the granite rocks that occasionally protrude above its surface, or of volcanic rocks of black scoria that frequently interrupt the general level; hills of this nature also constitute the greater portion of the more elevated islands off the coast, Cape Lambert, and the promontory that shelters the western side of Nickol Bay. The generality of these rocks do not, however, yield so rich a soil as might be expected from their origin. This is owing to the absence of actual lava, the eruptive heat having nearly been sufficient to convert the superincumbent primary and tertiary rocks into a vitreous scoria, having a specific gravity of 3.2, and is highly indestructible in its texture.
