When off Cape Blanco, the high land of Espinosa, in the interior, was clearly distinguished at a distance of sixty miles, and might probably be seen twenty miles further; so that its height must be, at least, four thousand feet. This range is of irregular form, and has several peaked summits, so very different from the general features of this coast, where the heights are either flat-topped, or of an undulating outline, that I suppose the rock to be of a character unlike that of the porphyry hills common hereabouts.
On anchoring off Port Desire (14th), we found that the Beagle had arrived, but had not met the Adelaide. The following afternoon I landed to examine the Tower Rock, a very conspicuous object, on the south side of this harbour, having the appearance of an enormous dead tree with its branches lopped off. On our way to it we passed over an undulating plain, composed of a sandy light soil, lying on a rocky basis, which in many parts protruded. The soil was so poor, as only to produce a few tufts of grass, and here and there a straggling bush of Berberis, or Piccoli, a dwarf woody shrub, which is much esteemed as firewood by the sealers who frequent the coast. Sir John Narborough, in describing this place, says, "The soil is gravelly and sandy, with tufts of dry seared grass growing on it;" again: "from the tops of the hills I could see a great way into the land, which is all hills and downs, like Cornwall, toilsome travelling to those who were not used to it."
The Tower Rock is evidently the remains of what was once probably a considerable rocky mass, which has either been partially destroyed by some convulsion, or, more probably, has been gradually worn away by the effect of weather. Like all the débris around, it is of a fine-grained red porphyritic claystone, much decomposed, but very hard, and difficult to break.[[114]]
It stands erect at the summit of a mound or heap of broken stones, of all sizes, some being very large blocks, from ten to twenty, or thirty tons weight. It is about forty feet high, and twelve in diameter, having its upper portion cleft, as it were, for about one-third down the middle, which gives it a resemblance to the forked branch of an immense tree. It is covered with moss and lichen, and, from its peculiar shape and prominent situation, presents a very remarkable object.
Near it we observed traces of an Indian visit, among which was a horse's skull. From the sterility of the soil and absence of fresh water, it is probable that it is but little frequented by them. Port Desire is celebrated as being the place where
Schouten, the Dutch navigator, is said to have found skeletons measuring eleven or twelve feet in length!
Captain Fitz Roy informed me that he had not seen the Adelaide since we separated. The Beagle had lost another boat in the gale; the eleventh we had lost in the expedition since leaving England. As the Adelaide did not make her appearance, I determined upon proceeding in the Adventure to Sea Bear Bay, a few miles to the southward of Port Desire, to await her arrival with the Beagle. While standing into the bay, we were amused by a chase of a novel description: a guanaco was observed following a fox, which had much difficulty in keeping his pursuer at a distance. As the guanaco is not carnivorous, it may have been in playfulness: Reynard, however, by his speed, and anxiety to escape, did not seem to think it an amusement. How the chase terminated we did not see, for they disappeared in a valley.
While the ship was being moored, I landed to examine some wells near the outer point, which have been said to afford some tuns of good water. I found them to be deep holes in the solid rock, within the wash of a heavy surf, and large enough to contain two hundred gallons of water; but in one only was the water fresh, the sea having broken into the others, and, of course, spoiled their contents. They receive the rain from the ravines, and are much depended upon by sealing vessels which frequent this coast.
Sea Bear Bay was discovered in the voyage of the Nodales, in the year 1618; they describe the place, but give it, as it deserves, a very poor character. "The port," they say, "for a short stay, is not bad, since it affords a good depth of water and a clear bottom; but otherwise it possesses nothing to make it worth a ship visiting it, for there is neither wood nor water, which are what ships most require." Nodales called the bay 'Sea Lion,' from the multitude of sea-lions (Phoca jubata) found on Penguin Island. Why it has been changed to Sea Bear Bay I cannot determine.
