The highest parts of the Mount form a ridge extending S.E. and N.W., being a succession of strata of slaty rock, dipping to the eastward, at an angle of 15° or 20° from the horizon. The strata are very narrow, and separated from each other by a vein of quartz, much of which is in a crystallized state. We reached the ship about seven o'clock, and found that the Hope and her party had done well. Her cruize proved interesting, with regard to the geography of the Strait, and a summary of it is subjoined.

Mr. Graves's orders were to survey the Sebastian Channel; but in the event of his seeing any thing more interesting to the S.E., he was allowed to defer that service to another opportunity. The Hope crossed the Strait, and anchored in a small bay, formed between the two projecting points of Cape Valentyn, where some few defects in the vessel were remedied, and a good round of angles obtained from the summit of the Cape, whence there was a fine view. The country was low, undulating, and destitute of trees. From a station about two miles overland, to the eastward, a large body of water was observed to the southward, forming a channel, or deep sound, and it was determined to follow up its examination, rather than risk the crew in the deep bay that was supposed to communicate with the San Sebastian Channel, on board a vessel whose capabilities were unknown. Several fire-places and remains of wigwams were seen; the latter were, however, very different, both in shape and material, from those at Port Famine, for the country being destitute of trees, they were built of driftwood, piled up in a conical form.

Passing round Cape Valentyn, the Hope hauled to the southward, keeping the land on board. At night she anchored in Philip Gidley Cove, at the bottom of Willes Bay, where she was weather-bound until the 29th of January. The shores of Willes Bay are thickly clothed with wood, growing to the water's edge, except at the S.W. side. The great abundance of muscles and limpets attracts the Indians, whose wigwams were found standing, and from the green appearance of the branches with which they were formed, seemed to have been lately erected. After leaving Willes Bay, the Hope visited Fox Bay, and Sir Edward Owen's Sound, which, it was thought, would lead into Lomas Bay, opposite to Port Famine; but, after running ten miles up, they got into shoal water, and as there was no current, or stream of tide, they landed, and found that a mile and a half farther on, the sound was terminated by low land. Another day, while proceeding along the south side of Brenton Sound, the smoke of Indians' fires was noticed near the beach. As this was the first time the Natives of this part had been seen, the course was shaped towards them, until the Hope anchored. Three Indians then approached, holding up the skins of some animal, and inviting them to land. The small boat was hoisted out, and Messrs. Wickham and Rowlett, with Robinson the pilot, went on shore. The Fuegians presented a fox skin to each of the party, who in return gave them some trifles. After a short interview the boat left them, and no further communication was held that night. The following morning a canoe came off to the vessel, containing three young men, two women, and three children, the youngest not more than four months old. They were no sooner alongside than the men went on board, and commenced an active traffic with all the valuables they possessed; and for a few buttons, a glass bottle, or an empty preserved-meat canister, many of their goods were bartered. They had several fox-skins with them, but no other kind of peltry, except their clothing, obtained from the seal or guanaco: and though many of them wore a penguin skin suspended from their girdle, some were without even that covering. This canoe was followed by another, containing an old man, sixty or seventy years of age, with a grey beard; an elderly woman, and two children. Before they came alongside they put their dogs on shore.

Although the visit from these Indians did not last very long, they had time enough to pilfer. One of the young men, who was seen going into a canoe, excited, by his manner, a suspicion of his having stolen something, and a tin pot was found concealed under his mantle. As there was every probability of their soon separating, and Mr. Graves feared that punishment would cause a rupture, he only turned him out of the vessel: the rest soon followed him, and landed. Having made a fire, the men squatted round it; while the women were despatched to collect shell-fish.

As soon as the Natives had finished their meal, they embarked, and proceeded eastward. Next day they again visited the Hope, but in consequence, perhaps, of the occurrence the day before, did not venture alongside, until invited by the words, 'ho-say, ho-say,' which mean, 'come, come.' In a few minutes confidence was restored, and they began to barter. The trade was opened by one of the women making a peace-offering of a shell necklace, in return for which, red caps and medals were given to each of the women and children. The Hope went thence to Soapsuds Cove, where the crew washed their clothes, and replaced a broken spar.

In a S.E. direction from this cove there appeared to be a considerable channel leading to the S.E., and to the southward was a deep sound, towards which they were proceeding the next morning; but having advanced about two miles, the land of Cape Expectation trended suddenly round to the eastward, and a long narrow channel presented itself, which seemed likely to communicate with the Strait, to the southward of Port San Antonio. They proceeded through this channel, which takes a very straight course, and gradually narrows from Port Waterfall, where it is two miles and a half wide, to Passage Cove, where it is scarcely three quarters of a mile; and there they anchored.

Between Port Waterfall and Passage Cove, a party of Natives was seen; but, being probably the same who were met at Indian Cove, no attention was paid to their hallooings and fires of invitation.⁴⁷ The Hope came into the Strait, eastward of an opening then called Magdalen Sound; her passage must therefore have been through Sarmiento's 'San Gabriel' Channel.

At night, when between Cape Froward and Port San Antonio, a heavy squall from S.W. carried the little vessel rapidly towards Cape San Isidro, and, at daylight the next morning, she was in the position observed by us, while ascending Mount Tarn.

CHAPTER IV

Deer seen – Hope sails again – Eagle Bay – Gabriel Channel – 'Williwaws' – Port Waterfall – Natives – Admiralty Sound – Gabriel Channel – Magdalen Channel – Hope returns to Port Famine – San Antonio – Lomas Bay – Loss of boat – Master and two seamen drowned.

From Mr. Graves's report of the appearance of the channel to the S.E. of Dawson Island, I decided to proceed there as soon as the Hope was ready, for she required some alteration, and repairs.

A deer having been seen on Point St. Anna, Mr. Tarn landed, very early in the morning, eager for the prize, but could only get an ineffectual shot. At another time a few deer were seen by our party, near the river; but instead of returning with the information, they fired their guns, loaded with small shot only, which served but to scare them away. As the animal was new to us, and we had evidence of its being equally new to Science, I was anxious to procure a specimen, but never afterwards had an opportunity. Here Sarmiento saw the only deer which he mentions in his journal.

The morning of the 16th seeming more favourable, I set out in the Hope. The heights were covered with snow which had fallen the preceding night, the thermometer had been at freezing point, and much ice had formed; but the appearance of the weather deceived us: we had scarcely left the ship, when it began to rain, and by the time we reached Cape San Isidro the wind had freshened to a gale, which obliged me to anchor in Eagle Bay.

Having landed, a tent was pitched, and a blazing fire made to dry our clothes. In the evening the gale blew with great violence from S.W., and the Hope, at her anchor, sheered about by the squalls, was occasionally laid over so as to dip her gunwale under water.

The following day (17th), although the rain had ceased, the wind was still strong. Towards evening it fell, and early on the 18th we left Eagle Bay with a fresh breeze from E.N.E., and passed close to Port San Antonio; but were then delayed by calms and squalls. At noon a westerly wind sprung up, and we proceeded down the Gabriel Channel, with the wind aft, and the tide in our favour. Port Waterfall sheltered us for the night.

The apparently artificial formation of this channel is very striking. It seems to have been formerly a valley between two ridges of the range, in the direction of the strata (of which there are frequent instances, such as the valley in the Lomas Range, opposite Cape San Isidro, the valley of Valdez Bay, and one immediately to the north of the channel itself, besides many others), and that at some remote period the sea had forced its way through, effecting a communication between the Strait and the waters behind Dawson Island: as if one of those great 'northern waves,' of which we once heard so much, had rolled down the wide reach of the Strait (the parallelism of whose shores is also remarkable) from the north-west, towards Cape Froward; and finding itself opposed by the Lomas Range, had forced a passage through the valley until stopped by the mountains at Fitton Bay. Having imagined such a wave in motion, the reader may fancy it uniting with another northern roller from Cape San Valentyn, attacking the hills and carrying all before it, until Mount Hope, at the bottom of Admiralty Sound, arrested its course. I have already noticed the remarkably straight direction in which this curious channel trends. At both extremities the width may be from two to three miles; but the shores gradually approach each other midway, and the coast on each side rises abruptly to the height of fifteen hundred feet. The south shore, sheltered from the prevailing and strongest winds, is thickly covered with trees and luxuriant underwood, which, being chiefly evergreen, improve the scenery greatly, particularly in the winter season: the north shore is also well wooded for about two-thirds up; but the summit is barren and the outline very much serrated, as is usual in slate formations.

On the north shore we noticed some extraordinary effects of the whirlwinds which so frequently occur in Tierra del Fuego. The crews of sealing vessels call them 'williwaws,' or 'hurricane-squalls,' and they are most violent. The south-west gales, which blow upon the coast with extreme fury, are pent up and impeded in passing over the high lands; when, increasing in power, they rush violently over the edges of precipices, expand, as it were, and descending perpendicularly, destroy every thing moveable. The surface of the water, when struck by these gusts, is so agitated, as to be covered with foam, which is taken up by them, and flies before their fury until dispersed in vapour. Ships at anchor under high land are sometimes suddenly thrown over on their beam-ends, and the next moment recover their equilibrium, as if nothing had occurred. Again a squall strikes them, perhaps on the other side, and over they heel before its rage: the cable becomes strained, and checks the ship with a jerk, that causes her to start a-head through the water, until again stopped by the cable, or driven astern by another gust of wind.

At all these anchorages, under high land, there are some parts more exposed than others; and by watching for those places which are least troubled by these squalls, a more secure, or rather a more quiet, spot may be selected. I do not consider ships so anchored to be in danger if their ground tackle be good; but every thing that offers a stiff resistance must suffer from the fury of these blasts. In many parts of this country trees are torn up by the roots, or rent asunder by the wind; and in the Gabriel Channel the 'williwaws' bursting over the mountainous ridge, which forms the south side of the channel, descend, and striking against the base of the opposite shore, rush up the steep, and carry all before them. I know of nothing to which I can better compare the bared track left by one of these squalls than to a bad broad road. After having made such an opening, the wind frequently sweeping through prevents the growth of vegetation. Confused masses of up-rooted trees lie at the lower ends of these bared tracks, and show plainly what power has been exerted.

The southern shore of the channel is formed by the base of that range of hills, which extends, from the eastern side of the Magdalen Channel, towards the E.S.E. It is the highest part of Tierra del Fuego, and on it are several remarkable mountains, besides Sarmiento, towering over all.

Close to the east end of the Gabriel Channel is Mount Buckland, a tall obelisk-like hill, terminating in a sharp needle-point, and lifting its head above a chaotic mass of 'reliquiæ diluvianæ,' covered with perpetual snow, by the melting of which an enormous glacier on the leeward, or north-eastern side, has been gradually formed. This icy domain is twelve or fourteen miles long, and extends from near the end of the channel to Port Waterfall, feeding, in the intermediate space, many magnificent cascades, which, for number and height, are not perhaps to be exceeded in an equal space of any part of the world. Within an extent of nine or ten miles, there are upwards of a hundred and fifty waterfalls, dashing into the channel from a height of fifteen hundred, or two thousand feet. The course of many is concealed, at first, by intervening trees, and, when half-way down the descent, they burst upon the view, leaping, as it were, out of the wood. Some unite as they fall, and together are precipitated into the sea, in a cloud of foam; so varied, indeed, are the forms of these cascades, and so great their contrast with the dark foliage of the trees, which thickly cover the sides of the mountain, that it is impossible adequately to describe the scene. I have met with nothing exceeding the picturesque grandeur of this part of the Strait.

There are several coves on the south shore, but opposite to them there is no shelter until you reach a deep bay in which are several islets; and where, I think, there is a communication with Brenton Sound, but we did not enter it.

Port Waterfall may easily be known by a large flat-topped bare rock, lying across the summit of the eastern head, and by a magnificent cascade formed by the union of two torrents.

All the plants of the Strait grow here: a sweet-scented Callixene (C. marginata, Lam^k.) filled the air with its odour; and a beautiful flower we had not previously seen, was found by Mr. Graves: it was pendulous, tubular, about two inches long (Class. Hexand. Monog. Cal. 2 Pet. 3. pointed), and of a rich carnation colour.

The trees are small and stunted; they are of the usual species, Beech and Winter's-bark. Here we first noticed a large fern,⁴⁸ having a stem two or three feet long, and five or six inches in diameter, very similar to the Zamia of New Holland. We saw very few birds, and no quadrupeds. Among the former was a king-fisher, which at the time was new to us; but it is distributed over a large tract of South America, and I have since seen a specimen said to have been shot at Rio de Janeiro.

Fitton Harbour is a deep inlet, surrounded on all sides by precipitous land, rising to the height of three, or four thousand feet, and terminated by peaks, of most fantastic shape, covered with ice and snow.

Between Fitton Harbour and Cape Rowlett are high mountains, two of which, more conspicuous than the rest, we called 'Mount Sherrard,' and 'Curious Peak.'

Card Point proved to be clay-slate, and I think the projection of Cape Rowlett, and the mountains, are also of this rock.

While crossing over towards Cape Rowlett, (the south head of a deep sound, trending to the S.E., which it was my intention to examine), we were met by three canoes, containing, together, about twenty-four people, and ten or twelve dogs. Mr. Wickham recognised them to be the same party who had visited the Hope on her last cruize; the thief, however, was not amongst them, fearing probably he might be known.

These natives conducted themselves very quietly, and, except one of the women, who wished to keep a tin-pot in which some water had been given her, made no attempt to pilfer. One of the party, who seemed more than half an idiot, spit in my face; but as it was not apparently done angrily, and he was reproved by his companions, his uncourteous conduct was forgiven.

If possessed of any furs, they had left them, perhaps concealed, near their wigwams: only a few arrows, a necklace of shells, and a fillet for the head, made of ostrich feathers, were obtained by barter. Their canoes were paddled by the women, occasionally helped by the men. One or two of the former were young, and well-featured, but the rest were hideous; and all were filthy and most disagreeable, from the quantity of seal-oil and blubber, with which they had covered their bodies. After we had obtained, by barter, all the articles they had to dispose of, I presented them with red caps and medals, of which they were very proud: the latter they requested might have a hole drilled through them, that they might be suspended by a string round their necks. Their astonishment was much excited, and they were pleased by hearing a watch tick; but I believe I had very nearly, though unintentionally; given great offence, by cutting off a lock of hair, from the head of one of the men. Assuming a grave look, he very carefully wrapped the hair up, and handed it to a woman in the canoe, who, as carefully, stowed it away in a basket, in which she kept her beads and paint: the man then turned round, requesting me, very seriously, to put away the scissors, and my compliance restored him to good-humour.

The features of these people bore a great resemblance to those of the Patagonian Indians, but in person they were considerably shorter and smaller. The elderly people of both sexes had hideous figures; the children, however, and young men, were well-formed; particularly one of the boys, whom they called 'Yāl-lă-bă,' which, I believe, meant a youth, or a young warrior. The word 'Shērrōo' was used to denote a canoe, or vessel.

They were ill-clothed, with mantles made of guanaco, or otter skins, but not so neatly as those of the Patagonians. Their bodies were smeared over with a mixture of earth, charcoal, or red-ocre, and seal-oil; which, combined with the filth of their persons, produced a most offensive smell. Some were partially painted with a white argillaceous earth; others were blackened with charcoal; one of the men was daubed all over with a white pigment. Their hair was bound by a fillet of plaited twine, made perhaps with strips of bark, and a few of them had it turned up; but to none did it appear to be an object of attention, except one of the young women, who repeatedly combed and arranged her's with the well-toothed jaw of a porpoise.

During a remarkably calm night, we were frequently startled by the loud blowing of whales, between us and the shore. We had noticed several of those monsters on the previous day, but had never heard them blow in so still a place.

At dawn, a light air carried us towards some broken land to the S.E. of Cape Rowlett, between the eastern trend of which, and the projecting point of an island, we found a secure and land-locked harbour, with two entrances, one to the north and the other to the south of High Islet. The south side of the port, which I called Port Cooke,⁴⁹ is a narrow strip of land, forming the head of a deep inlet or sound, called⁵⁰ Brook Harbour. It seemed to extend to the base of the high mountainous range, and to be separated only by a narrow isthmus from Fitton Harbour.

We had scarcely been at anchor half an hour when the same party of Fuegians was seen arriving. The men hastened to us in their canoes, as soon as the women had landed, to cover or thatch the wigwams, which they found standing, and to light fires.

We afterwards went ashore, and, sitting down near them, commenced a brisk trade for arrows, skins, necklaces, and other commodities. The furs which covered their backs they parted with, for a few beads, and went quite naked the whole evening.

Among them was a young man, who appeared to be treated with some deference by the others; he was one of the best-looking of the party; and there was a good-natured smile on his countenance during our communication, while the rest frequently manifested displeasure, even about trifles. He was, at least, the master of one of the two families; his wigwam contained his wife, and two children, his, or his wife's father, and mother, as well as the idiot, and his wife, who, from her appearance, must have been a Patagonian, or else a woman of unusual size among these people. The old woman was very inquisitive, and the man, in a long speech, described to her all the wonders I had shown him, applying to me, from time to time, to point out to her the articles he was trying to describe.

Their dexterity with the sling is extraordinary; and, I should think, when used as a weapon of offence, it must be very formidable. Upon asking the same man to show us its use, he picked up a pebble, about the size of a pigeon's egg, and placed it in the sling; then intimating that he was going to strike a canoe, he turned his back to the mark, and threw the stone in an opposite direction, against the trunk of a tree, whence it rebounded over his head, and fell close to the canoe.

I have seen them strike a cap, placed upon the stump of a tree, fifty or sixty yards off, with a stone from a sling. In using the bow and arrow, also, with which they kill birds, they are very dexterous. The spear is principally for striking porpoises and seals, but is also used in war; and from the nature of the barb, must be an efficient weapon. For close quarters, they use clubs, stones held in the hand, and short wooden daggers, pointed with very sharp-edged quartz, pitch-stone, or flint.

The next morning, seeing us underweigh, they came alongside and tried to induce us to anchor again. The young man, of whom I have spoken, was very importunate, and at last offered us his wife, as a bribe, who used all her fancied allurements to second his proposal.

So highly did they esteem beads and buttons, that a few of each would have purchased the canoe, the wife, and children, their dogs, and all the furniture. Seeing us proceed to the southward, with the apparent intention of sailing down the inlet, they motioned to us to go to the north, repeatedly calling out 'Sherroo, sherroo,' and pointing to the northward; which we thought intimated that there was no passage in the direction we were taking.

At noon, I landed to observe the latitude, and take bearings down the Sound to the S.E., at the bottom of which was a hill, standing by itself, as it were, in mid-channel. The view certainly excited hopes of its being a channel; and as we had begun to calculate upon reaching Nassau Bay in a few days, we named this hill, Mount Hope.

The point on which we landed was at the foot of a high snow-capped hill, called by us Mount Seymour; whence, had not the Indians been near, I should have taken bearings.

We sailed south-eastward, close to the south shore, until the evening; when from the summit of some hills, about three hundred feet above the sea, we had a view down the Sound, which almost convinced us it would prove to be a channel. The rock at this place differed from any we had seen in the Strait. The mountains are high, and evidently of clay-slate; but the point, near which we anchored, is a mass of hard, and very quartzose sand-stone, much resembling the old red sand-stone formation of Europe, and precisely like the rock of Goulburn Island, on the north coast of New Holland.⁵¹

The following morning (23d), we proceeded towards Mount Hope, while running down to which some squalls passed over, clouding the south shore, and as we passed Parry Harbour it bore so much the appearance of a channel, that we stood into it; but the clouds clearing away soon exposed the bottom to our view, where there seemed to be two arms or inlets. In the south-eastern arm, the shores were covered with thick ice (like the bottom of Ainsworth Harbour, to the west of Parry Harbour, where an immense glacier slopes down to the water's edge). The south-west arm appeared to be well sheltered, and if it affords a moderate depth of water, would be an excellent harbour.

After satisfying ourselves that there was no channel here, we bore up on our original course; but, before long, found ourselves within two miles of the bottom of the Sound; which is shallow, and appears to receive two rivers. The great quantity of ice water, which mingles here with the sea, changed its colour to so pale a blue, that we thought ourselves in fresh water.

Mount Hope proved to be an isolated mass of hills, lying like the rest N.W. and S.E., having low land to the southward, over which nothing was visible except one hill, thirty or forty miles distant, covered with snow, to which the rays of the sun gave the appearance of a sheet of gold. Finding ourselves embayed, we hastened out of the scrape, and, after beating for some hours, anchored in Parry Harbour.

Our entrance into a little cove in Parry Harbour disturbed a quantity of ducks, steamers, shags, and geese. Their numbers showed that Indians had not lately visited it.

Next day we reached Ainsworth Harbour, which is of the same character as Parry Harbour, and affords perfect security for small vessels: by dint of sweeping, we reached a secure anchorage in a cove at the south-east corner.

The bottom of the port is formed, as I before said, by an immense glacier, from which, during the night, large masses broke off and fell into the sea with a loud crash,⁵² thus explaining the nocturnal noises we had often heard at Port Famine, and which at the time were thought to arise from the eruption of volcanoes. Such were also, probably, the sounds heard by the Spanish officers during their exploration of the Straits, whilst in the port of Santa Monica, where they had taken refuge from a violent gale of wind.⁵³

The harbour was full of fragments of ice, the succeeding morning, drifting into the Sound, where the sea-water, being at a higher temperature than the air, rapidly melted them.

Since our departure from Port Waterfall, the weather had been mild, clear, and settled; but as it wanted only three days of the change of the moon, at which period, as well as at the full, it always blew a gale, I wished to reach a place of security in the Gabriel Channel or Magdalen Sound.

Near the islands of Ainsworth Harbour, three canoes passed us, steering across the Sound, each with a seal-skin fixed up in the bow for a sail; and we recognised in them the party left at Port Cooke, among whom was the Indian who had been detected in stealing a tin pot. They did not come along-side; but as we went by, pointed to the north, apparently urging us to go in that direction.

We had noticed several wigwams at Parry and Ainsworth Harbours, which shows that they are much frequented by Indians, perhaps on their way to the open low country east of Mount Hope, where numerous herds of guanacoes may be found.

Porpoises and seal were not scarce in this inlet, and in the entrance there were many whales. The presence of seal and whales made me think it probable there was a channel; but I believe every person with me was satisfied of its being a sound, terminating under Mount Hope. Since my later experience of the deceptive character of some passages in Tierra del Fuego (the Barbara Channel, for example), I have felt less certain that there may not be a communication with the low land, behind Mount Hope, round its northern base. The improbability was, however, so great, – from the bottom of the sound being shoal, – from the very slight tide-stream, – and from the information of the Natives; who evidently intended to tell us we could not get out to sea, – that we did not consider it worth while to make another examination.

I have before observed that the strata of the slate rocks, in the Strait, dip to the S.E.; and I found that they dip similarly all the way to the bottom of this inlet, which I named Admiralty Sound.

The north side, like that of the Gabriel Channel, is steep, without indentations, excepting where there is a break in the hills; but on the south shore there are many coves, and bights, the cause of which is shown in the accompanying imaginary section of the Gabriel Channel. The same cause operates on the outline of the north shore of the reach of Cape Froward, westward as far as Cape Holland, where the rock assumes a still more primitive form. Its general character, however, is micaceous slate, with broad veins of quartz; the latter being particularly conspicuous at Port Gallant.

The following slight sketch, intended to represent an imaginary section of such an opening as the Gabriel Channel, may also serve to give a general idea of many Fuegian anchorages; – of deep water passages existing between the almost innumerable islands of Tierra del Fuego; – and of the effects of those sudden, and violent gusts of wind, – so frequent and dangerous, – commonly called hurricane-squalls,⁵⁴ or williwaws.

The rock, of course, decomposes equally on both sides; but on that exposed to the south wind, it breaks off in flakes parallel to the direction of the strata, and therefore does not make the course of the beach more irregular; while on the other side it moulders away transversely to the direction of the dip, leaving holes, in which water lodges, and hastens decomposition by entering deeply into the interstices. Water, air, and frost decompose the rock, and form a soil, which, if not too much exposed to the wind, is soon occupied by vegetation.
