comparative facility offered by the water-course, was only impeded by loose stones, which frequently yielded to the foot, and rolled down the gully, to the great danger of those who followed. The banks of the ravine were saturated with water, and covered either with spongy moss, or matted with plants,[[119]] which afforded no assistance; had it not therefore been for straggling shrubs of arbutus, or veronica, and tufts of rushes, growing on the steeper parts, we should have had many a fall; and however unimportant we might think bruises and scratches, a broken barometer would have been a serious accident, and much care was required to avoid it. We had to leave the bed of the torrent, when it became full of wood, and then our difficulty increased much; for in many places we had to scramble over the thickly-matted and interwoven branches of the stunted bushes of beech which frequently yielded to our weight, and entangled our legs so much, that it was no easy matter to extricate ourselves.
At the height of one thousand feet, vegetation became much more stunted; we found the plants and shrubs of very diminutive size, consisting principally of the deciduous-leaved beech, one plant of which, though not more than two inches high, occupied a space of four or five feet in diameter, its spreading branches insinuating themselves among wild cranberry, chamitis, donacia, arbutus, and escalonia, so closely matted together, as to form quite an elastic carpet. For the last two hundred feet, we walked over the bare rock, on which no other vegetation was observed than lichens. The summit of the peak is formed by a loose pile of green-stone rock, in which the hornblende appears in very varied forms, sometimes in large crystals, and again so small and disseminated, as to be scarcely visible; on the summit it is seen, in very long, narrow (? filiform) crystals, and the feldspar predominating, gives it a white appearance.[[120]]
The only living creatures we saw were a solitary hawk and
one insect, a species of Oniscus. Nothing, in fact, could be more desolate, and we had only the satisfaction of a good observation for the height, and an excellent bird's-eye view of the surrounding islands and channel, to repay us for the labour of the ascent. On reaching the top, the barometers were suspended under the lee of the rock, twelve feet below its summit, and I then proceeded to set up the theodolite, which I found more damaged than I had anticipated; but not so much as to deprive me of a very extensive round of angles, in which were contained bearings of the Ildefonso Islands. We were thus occupied about an hour and half, which afforded me an opportunity of obtaining two good readings of the barometer.
The view to the N.W. was very extensive, and bounded by long ranges of snow-clad mountains of great height; the atmosphere was remarkably clear, and every object unusually distinct. Bearings of the islands of Diego Ramirez would have been taken, but for the extreme force of the wind, which more than once blew me from the theodolite, and once actually threw me on the ground. The temperature was not below 38°; but, owing to the wind, the cold was intense, and the rapid evaporation produced the most painful sensations, particularly in our feet and legs, which were thoroughly wet when we reached the top.
Our descent was not effected in less than an hour and twenty minutes, owing to the difficulty of passing through the beech thickets; but we reached the base without injury to the barometers, which was being more fortunate than I expected. They were again set up on the beach, and read; after which we returned on board, amply gratified and rewarded for our fatigue.
The height of the peak, which, from its vicinity to the station selected by Captain Foster for the pendulum experiments, could not receive a more appropriate name than Kater's Peak, was found to be 1,742 feet above the high-water mark.[[121]]
The next day, after a beautifully clear and mild morning, with a fresh northerly breeze, the weather became cloudy, and the wind veered to the S.W. blowing excessively hard, with hail and rain. The gusts, or williwaws, rushed through the valley of the cove with inconceivable violence, heaving the ship over on her broadside every minute, so that we were obliged to have every thing lashed as if at sea. Fortunately, we had completed wood and water, and now only waited for observations, to rate the chronometers, for our run to Valparaiso, whither it was my intention to proceed. Days, however, passed without a glimpse of the stars, and the sun only appeared for a few minutes above the hills. Captain Foster had completed his observations, and embarked all his instruments, excepting the transit, which remained for taking the passages of stars; but the bad weather continued, with little intermission. On the 3d, the gale was most violent, and the williwaws became short hurricanes, in some of which the ship drifted and fouled her anchors. On the 10th, we had a dry and fair day, which permitted us to sight the anchors and moor again.
The fine weather was of only a few hours duration, when the gale again sprung up, and lasted, with little intermission, until the day of our departure (the 24th). From the 4th to the 22d the sky was so perpetually clouded, that the only transits obtained in that interval were, one of Antares, one of Regulus, and one of the limb of the moon, though Captain Foster even slept close to the telescope, in the greatest anxiety to obtain observations. On the night of the 22d four stars were
