Robert Fitzroy - Narrative of the surveying voyages of His Majesty's ships Adventure and Beagle, between the years 1826 and 1836

I am averse to altering names, particularly in natural history, without very good reason, but in this case I do think the name of 'steamer' much more appropriate, and descriptive of the swift paddling motion of these birds, than that of 'race-horse.' I believe, too, the name of 'steamer' is now generally given to it by those who have visited these regions.

Many shells 36 36 On the shores of Eagle Bay we procured a large collection of shells, among which were Margarita violacea (Nob. in Zool. Journ. v. 346, No. 53), a beautiful Modiola ( M. trapesina , Lam. k ), a new Pecten (P. vitreus Nob. in Zool. Jour. v. 337, No. 17), and a delicate transparent-shelled Patella , answering the description of P. cymbularia . These four species were found attached to floating leaves of the kelp ( Fucus giganteus ), and afford food to the steamer-duck. We also collected good specimens of Murex Magellanicus , Lam. k , of Fissurella picta , Lam. k , and a great number of the common patella of the Strait, which forms a considerable article of food for the Natives. were taken from the bottom by means of a fizgig which Mr. Tarn found in one of the wigwams: it was a rough pole, eight or ten feet long, split crosswise at one end, and opened so as to form four prongs, kept apart by two small pieces of wood. Although rudely made, it was excellently adapted for a shell-gatherer, and is used by the Indians for collecting sea-eggs, which are found in the Strait of very large size, and are doubtless, to them, a great delicacy.

During our excursion we ascertained the best place to ascend the snowy mountain, since named 'Tarn;' and the surgeon, whose name it bears, set off with a party of officers to make the attempt, in which he succeeded, and obtained such an extensive view as induced me to decide upon ascending it, a few days afterwards, to procure bearings from the summit, and for the purpose of measuring its height with a barometer.

In the meantime I visited the Sedger river (Sarmiento's 'Rio de San Juan de Posesion'), and found some difficulty in entering it, because of several banks which are dry at low water. Between them, however, the stream keeps a small channel open, by which we effected our purpose. Every gale of wind causes the banks to shift, and between the times of our first, and last, visit to Port Famine, the river's mouth underwent many changes. The bed of the river is so full of fallen trees, that we could not go, with the boat, more than three miles and a half above the entrance; there it was about fifteen yards wide, bounded on each side by thickly wooded banks, of moderate height. The trees on these banks are large, chiefly the two species of Beech before-mentioned, and Winter's-bark; there are besides many shrubs, and an impenetrable underwood of Arbutus, Berberis, and currant bushes. The largest Beech-tree that we saw could not have been more than thirty or forty inches in diameter, which was insignificant compared with those noticed by Commodore Byron. In describing his excursion up this river, he mentions "trees that would supply the British navy with the best masts in the world." 37 37 Byron's Voyage round the World, 4to. p. 38. "Some of them are of a great height, and more than eight feet in diameter, which is proportionally more than eight yards in circumference." 38 38 l. c. The Commodore may have been pleased by the appearance of these trees, but must have fancied their quality and dimensions such as he describes. The largest are generally rotten at the heart, and all are more or less defective. Their wood is heavy, and far too brittle for masts: we could not use it even for boat-hook staves. It makes, however, tolerable plank for boat-building, and, when seasoned, might be used in ships. For common purposes, such as houses, or fences, it is very serviceable.

We wandered about to examine the country; but, excepting the track of some quadruped, whose foot was small and cloven, rather like a pig's, we saw nothing new. The traces of foxes were numerous every where. We found no fish of any description in the river. Geese and wild ducks were numerous, whose young were at this time scarcely fledged, and an easy prey. We also observed here, for the first time, the parroquet, which Bougainville described to be common in the Strait. He carried specimens home with him; but some naturalists of those days decided that there must have been a mistake, because, as they averred, parroquets did not exist in so high a latitude. Bougainville, however, made no mistake, for the species 39 39 Psittacus smaragdinus , Gmel. I have no doubt that the bird we saw is the same as Bougainville procured, and from which a description has been given in the Ency. Méth., art. Ornith. 139; although a material error is made, for they are not splendidé viridis , nor is the uropygium red, in other points, however, the description is correct. See Buffon's Hist. Nat. des Oiseaux, vi. 262. Pl. enl. n. 85, Perruche des Terres Magellaniques. is very abundant in the neighbourhood of Port Famine, and has been seen by us in all parts of the Strait. It feeds principally upon the seeds of the Winter's-bark. The existence of this bird in Tierra del Fuego is also mentioned by Cook and Narborough. 40 40 Bougainville says, "we have likewise perceived some perrokeets: the latter are not afraid of the cold." To which the English translator, T. R. Forster, who is incredulous of the correctness of Bougainville's assertion, appends the following note: "Perruches, probably sea-parrots, or auks." Buffon also doubted the fact, and the author of Histoire Naturelle, art. Oiseaux, tom. ii. p. 322, suggests the possibility of a specimen having been obtained in some other part of the world, and put, by mistake, amongst those collected in the Strait.

All accounts of Port Famine informed us of its abounding in fish, but as yet we had taken none excepting with hook and line, although the seine had been frequently shot. At last, however, in the first week of February, we had a successful haul of mullet and smelts, many of the former weighing eight pounds, and the latter measuring fifteen inches in length. After this we were often very fortunate, and on one occasion caught, at one haul of the seine, sixteen hundred-weight of smelts, some weighing two pounds, and measuring twenty inches in length. A few days previously we had a draught of mullet, which served the crews of both Adventure and Beagle for three days. Geese, wild ducks and teal, snipe, and now and then woodcocks, were to be found by taking a short walk; there were, however, no quadrupeds fit for food which we could take. Foxes and wild cats were occasionally seen, and a foot-mark of some large animal of the feline race, probably a puma, was once observed upon the beach. We found many traces of horses, which showed that the Patagonian Indians sometimes come thus far south. Had we been so fortunate as to meet them here, we might have procured, perhaps, a regular supply of guanaco meat.

On the 9th of February, as the weather seemed favourable for ascending Mount Tarn, 41 41 So named because Mr. Tarn, the surgeon of the Adventure, was the first person who reached its summit. Lieutenant Cooke, the Surgeon, and Anderson, the botanical collector, set off in advance to select a convenient place for passing the night, carrying with them a tent and provisions. I followed later in the day, and, while the boat's crew were arranging their loads, made some observations with a barometer on the beach.

Our way led through thick underwood, and then, with a gradual ascent, among fallen trees, covered with so thick a coating of moss, that at every step we sunk up to the knees before firm footing could be found. It was very laborious work, and the ground being saturated, and each tree dripping with moisture, we were soon wet through. We proceeded along the same sort of road up a steep ascent; some one of the party constantly falling into deep holes covered by moss, or stumbling over fallen trunks of trees. As I carried a barometer I was obliged to proceed with caution, and succeeded in emerging from this jungle without accident. After about three quarters of an hour spent in this way, we reached an open space, where we rested, and I set up the barometer. Here we found a cypress of very stunted growth.
