observed, by which the error of the clock was satisfactorily ascertained.
Captain Foster's pluviameter, a cubic foot in size, placed on a stand two feet above the ground, at an elevation of forty-five feet above the sea, contained eight inches and a quarter of rain, after standing thirty days; therefore, with the quantity evaporated, at least twelve inches must have fallen. The day after the above was registered, the vessel only contained seven inches and a quarter; so that in twenty-four hours one inch had evaporated, by which an idea may be formed of the sort of weather we experienced, and of the humidity of the climate.
With respect to the geological features, I can only add, that all the islands on which I landed, and, I believe, all the others, are composed of green-stone of various characters. The lower portion, or base, being less decomposed, is a fine-grained green-coloured rock, in which the component parts are so blended as not to be distinguished from each other. It appears sometimes in strata, dipping at various angles, from 20° to 45° from the vertical; and is very similar to the rock which alternates with granite in the Straits of Magalhaens, at the entrance of the Barbara; and also to that about Pond Harbour, and Bell Bay. At a greater elevation the feldspar predominates, the hornblende is observed in distinct crystals,[[122]] and the rock contains a considerable quantity of iron, which is observed in the reddish tinge of its surface. I have before noticed the magnetic property of this rock, which was more or less according to the quantity of hornblende: the beach-stones are different sorts of green-stone.
The lower parts of the hills, around St. Martin's Cove, are thickly wooded with the smooth-leaved, evergreen beech, which I have before described. Its leaves were as fresh and vivid, when we sailed, as if it were the height of summer; but those of the deciduous-leaved beech had assumed their autumnal tint, and were falling fast. Neither species attained a greater size, in diameter, than six or eight inches. The Winter's-bark was
found in sheltered places, but not larger in dimensions than the beech.[[123]] Where no trees are produced, the ground is covered with tufts of chamitis and donacia, which, being of a bright-green colour, give the sides of the hills a lively and verdant appearance. Had the state of the weather permitted our boats to leave the neighbourhood of the cove, or had the woods afforded any addition to collections for natural history, our detention would have been more agreeable; but, with the exception of a few corvorants, divers, and 'steamers,' with now and then a solitary hawk, or a Patagonian 'warbler,' we saw no traces of animal life. No Indians came near us, having been frightened away by the Chanticleer; for when Captain Foster was absent at night, after attempting to land at Cape Horn, several rockets were fired off as signals, and a few Indians who were then in the cove were so much alarmed, that they went away next day, and never afterwards showed themselves, although I dare say we were very narrowly watched by them.
Having supplied the Chanticleer with the provisions she required, we prepared to leave St. Martin's Cove. On the 24th the Chanticleer sailed, and in two hours after we also left this dismal cove, in which we experienced a succession of very bad weather, an almost constant S.W. wind, and for the last month a scarcely ceasing fall of either rain, hail, or snow. The Chanticleer bore away round Cape Horn, and was soon out of sight.
This was my last meeting with Captain Foster, who, the night before we sailed, communicated to me a presentiment, which he could not shake off, that he should not survive the voyage. I cannot now resist indulging in the melancholy satisfaction of saying a few words to the memory of my late excellent
friend, and lamenting, with many others, the severe loss which science suffered in his death. He was a fellow of the Royal, and Astronomical Societies, and to the former had contributed, to use the words of His Royal Highness the Duke of Sussex, as President of the Royal Society, a most valuable and extensive series of observations upon the diurnal variation, diurnal intensity, and dip of the magnetic needle; and upon other subjects connected with the terrestrial magnetism and astronomical refraction, which formed an entire fourth part of the Philosophical Transactions for the year 1826. For these papers he received the Copley medal; and the Lords of the Admiralty acknowledged their sense of the honour which was thus conferred upon the profession to which he belonged, by immediately raising him to the rank of Commander, and by appointing him to the command of the Chanticleer, upon a voyage of discovery and observation in the South Seas. The address of the President of the Royal Astronomical Society, at the anniversary meeting,[[124]] also bears ample testimony to his active and useful services in the expedition, under Captain Parry, towards the North Pole; as well as to his ardent zeal, very great attention, and accuracy, in every thing which he undertook for the promotion of science; and concludes the notice of his death in the following words: "In the premature death of this young and accomplished officer, the Society has to deplore the loss of a zealous and active votary to science; and his memory will be long held dear by those who were more intimately acquainted with him in the relations of private life." Captain Foster was unfortunately drowned, near the close of his voyage, while descending the River Chagres in a canoe.
No sooner had we cleared the land, than we found a strong westerly wind, and a heavy sea; so that if we had entertained any expectation of making a quiet passage to the westward, we should have been disappointed.
The land of Hermite Island, and its vicinity, has a most remarkable appearance when seen from the south. Its outline is a series of peaks, following each other in regular succession,
