Between Matunza and Orotara the vegetation is magnificent, and the luxuriant foliage of the vine enhances the beauty of the view. Orotara is a small seaboard town, with a port affording but little shelter. It is well-built and laid out, and would be comfortable enough if the streets were not so steep as to make traffic all but impossible. After three-quarters of an hour's climb through well-cultivated fields, the Frenchmen reached the chestnut-tree region, beyond which begin the clouds, taking the form of a thick moist fog, very disagreeable to the traveller. Further on comes the furze region, beyond which the atmosphere again becomes clear, vegetation disappears, the ground becomes poorer and more barren. Here are met with decomposed lava, scoria, and pumice-stones in great abundance, whilst below stretches away the boundless sea of clouds. Thus far hidden by clouds or by the lofty mountains surrounding it, the peak at last stands forth distinctly, the incline becomes less steep, and those vast plains of intensely melancholy appearance, called Canadas by the Spanish, on account of their bareness, are crossed. A halt is made for lunch at the Pine grotto before climbing the huge blocks of basalt ranged in a circle about the crater, now filled in with ashes from the peak, and forming its enceinte. The peak itself is next attached, the ascent of which is broken one-third of the way up by a sort of esplanade called the Estancia de los Ingleses. Here our travellers passed the night, not perhaps quite so comfortably as they would have done in their berths, but without suffering too much from the feeling of suffocation experienced by other explorers. The fleas, however, were very troublesome, and their unremitting attacks kept the commander awake all night. At four a.m. the ascent was resumed, and a second esplanade, called the Alta Vista, was soon reached, beyond which all trace of a path disappears, the rest of the ascent being over rough lava as far as the Chahorra Cone, with here and there, in the shade, patches of unmelted snow. The peak itself is very steep, and its ascent is rendered yet more arduous by the pumice-stone which rolls away beneath the feet. "At thirty-five minutes past six," says M. Dumont d'Urville, "we arrived at the summit of the Chahorra, which is evidently a half-extinct crater. Its sides are thin and sloping, it is from sixty to eighty feet deep, and the whole surface is strewn with fragments of obsidian, pumice-stones, and lava. Sulphureous vapour, forming a kind of crown of smoke, is emitted from it, whilst the atmosphere at the bottom is perfectly cool. At the summit of the peak the thermometer marked 11 degrees, but in my opinion it was affected by the presence of the fumerolles, for when at the bottom of the crater it fell rapidly from 19 degrees in the sun to 9 degrees 5' in the shade."
