but the two streams were very insignificant, not longer at the utmost than three quarters of a mile each. I had no idea of the meaning of a "sea of rocks" until I crossed them; the edges of the stony billows were so sharp, that it was very difficult to pass among them without cutting one's clothes into shreds. I at last arrived at the cone: it was, I suppose, of the ordinary steepness of such heaps of volcanic cinders, but much higher. I estimate it at 1500 feet from the hollow from which it appears to have sprung. It looks as if a vast amphitheatre had been hollowed out of the surrounding mountains, in order to place it in. The sides of all the mountains around are quite perpendicular, and present a most magnificent scene. A circular plain of sand at the north-east base would have been a fitting scene for the wildest piece of diablerie that ever entered the brain of a German, or was embodied by his pencil. Thermometer at base of cone, fine sunshine, 65° in sun; no shade to be had. Barometer, 2514⁄20.
The cone is entirely composed of loose cinders, and I was heartily tired of the exertion before I reached the top. Had it not been for the idea of standing where no man ever stood before, I should certainly have given up the undertaking. A few patches of a most beautiful snow-white veronica, which I at first took for snow, were growing among the stones; but they ceased before I had ascended a third part of the way. A small grass reached a little higher; but both were so scarce that I do not think I saw a dozen plants of each in the whole ascent. After I had ascended about two-thirds of the way, I got into what appeared a water-course, the solid rock of which, although presenting hardly any projecting points, was much easier to climb than the loose dust and ashes I had hitherto scrambled over. It was lucky for me another eruption did not take place while I was in it, or I should have been infallibly boiled to death, as I afterwards found that it
