Several times during the day the fog cleared away for a while, and gave us grand views of the coast on either hand. That of the Land of Desolation especially attracted my attention. Captain Willsen pointed out to me, as we stood on the bridge, to which I had free access, the opening of a narrow sound which has lately been ascertained to penetrate entirely through what used to be considered a single island. The expressive name must, indeed, be abandoned, for, if I am not mistaken, the Land of Desolation of our maps is already known to consist of three, and may possibly form many more islands, divided from each other by very narrow channels. Our cautious commander resolved once again to anchor for the night, and selected for the purpose Borya Bay, a small sheltered cove some distance east of Port Gallant, a harbour often visited by the English surveying-expeditions. Daylight had departed when, about half-past five, we reached our anchorage; but the sky was again quite clear, and we enjoyed the weird effects of moonlight illumination. The scenery is very grand, and was more wintry in aspect than at any other point in our voyage. A mountain at the head of the cove rose steeply to a height of at least two thousand feet, and cast a dark shadow over the ship as we lay very near the shore. The shores were begirt with the usual belt of forest, but this did not extend far, and the declivities all around were clad with snow, which lay rather deep. It appeared to me that a rather large glacier descended to within a few hundred feet of the shore, but, seen by the imperfect light, I felt uncertain as to the fact. Since entering the Straits, I had noticed that on the steeper slopes facing the south, where the surface can receive but little sunshine at any season, the forest ascends but a short distance above the sea-level. Above that limit in such situations I observed only a scanty covering of bushes, and higher up the surface at this season appeared quite bare.
As Borya Bay is one of the customary haunts of the Fuegians, the steam-whistle was sounded on our arrival as an invitation to any natives who might be encamped there. This always suffices to attract them, with the hope of being able to gratify their universal craving for tobacco. The appeal was not answered, as the people were doubtless on the outer coasts, and we were not destined to see anything of the most miserable of all the races of man.
As the weather remained bright, the anchor was raised soon after midnight, and by one a.m. we were on our way, steering south-east, to round the southern extremity of the mainland of America. Awaking to the disappointment of having missed a view of one of the most interesting portions of the Straits, I hurried on deck, and found a new change in the aspect of the skies. The night had been cold, with a sharp frost; but in the morning, soon after daybreak, the air felt quite warm, with the thermometer marking 39° Fahr. A northerly breeze had set in, and as an inevitable result brought thick weather. I again noticed, however, that the barometer on these coasts seems to be very slightly affected by changes in the wind’s direction. It stood last night at 30·16 inches, and on the morning of the 10th, with a complete change of weather, had fallen only eight-hundredths of an inch.
MOUNT SARMIENTO.
The southern end of the continent is shaped like a broad wedge, whose apex is Cape Froward, laying in south latitude 53° 54′. We passed it early in the forenoon, giving the headland, which we saw dimly to the north, a broad berth, so that we about touched the 54th parallel. If we compare this with the climate of places in about the same latitude, as, for instance, with that of the Isle of Man, we are apt to consider the climate as severe; but we habitually forget how far the condition of Western Europe is affected by exceptional circumstances; and if we look elsewhere in the northern hemisphere, taking, for instance, the Labrador coast, the south of Kamschatka, or even the coast of British Columbia, we must admit that the Straits of Magellan afford no confirmation to the prevalent ideas respecting the greater cold of the climate of the southern hemisphere.
Soon after this turning-point of the voyage the sky partially cleared to the southward, and we were fortunate enough to enjoy one of the most impressive scenes that my memory has recorded. The broad sound that divides Clarence Island from the main island of Tierra del Fuego lay open before us, flanked on either hand by lofty snow-clad summits. In the background, set as in a frame, rose the magnificent peak of Mount Sarmiento, the Matterhorn of this region, springing, as it appeared, from the shore to a height of seven thousand feet.[34] Sole sovereign of these antarctic solitudes, I know of no other peak that impresses the mind so deeply with the sense of wonder and awe. As seen from the north, the eastern and western faces are almost equally precipitous, and the broad top is jagged by sharp teeth, of which the two outermost, one to the east, the other to the west, present summits of apparently equal height. At a distance of about twenty-five miles the whole mass seemed to be coated with snow and ice, save where some sharp ridges and teeth of black rock stood out against the sky. I remained for some time utterly engrossed by the marvellous spectacle, and at last bethought myself of endeavouring to secure at least an outline of the scene; but before I could fetch a sketch-book, a fresh change in the weather partly obscured, and, a few minutes later, finally concealed from my eyes a picture that remains vividly impressed on my memory.
It was impossible not to speculate on the origin and past history of this remarkable peak. Admitting that there is evidence to show that the larger part of the rocks of this region are of volcanic origin, it appeared to me evident not only that Mount Sarmiento is not a volcanic cone, but that the rock of which it is composed is not of volcanic origin. Whether its real form be that of a tower, or that of a ridge with precipitous sides seen in profile, no volcanic rocks elsewhere in the world can retain slopes so nearly approaching to the vertical. It is, I believe, a portion of the original rock skeleton that formed the axis of the Andean chain during the long ages that preceded the great volcanic outbursts that have covered over the framework of the western side of South America. Like most peaks of a similar form, I am disposed to believe that in the course of gradual upheaval the flanks have been carved by marine action to the nearly vertical form which impresses the beholder. Although snow-covered mountains suffer a certain limited amount of denudation in the channels through which glaciers flow, there is reason to hold that they are far less subject to degradation than those which are not protected from the main agencies that wear away rocky surfaces. It is by alternations of temperature, by frost, and the action of running water, that rocks are rapidly eaten away, and from these a snow-covered mountain is to a great extent secured.
CHANGE OF SCENERY.
A few miles east of Cape Froward the coast of the mainland trends nearly due north for a distance of fully sixty miles, and a marked change is perceived in the aspect of the shores. Instead of the bold outlines to which our eyes had become accustomed, the coastline lay low, fringed with forest on the side of the mainland, which now lay to our west, and on the other hand showing bare flats, here and there flecked with fresh snow. The land on that side at first belonged to Dawson Island; but later in the day, as we approached our destination, the dreary flats formed part of Northern Tierra del Fuego.
