“After gazing at the wonderful and wonderfully sublime scene for some twenty hours, taking but a little time for repose, we found the sense of fear subsiding, and curiosity prompting to a closer intercourse with Pele, and a more familiar acquaintance with her doings and habits. Many who try the experiment, though at first appalled, are ready after a few hours, to wend their way down the steep sides of the crater. Thus we descended into the immense pit from the north-east side, where it was practicable, first to the black ledge or amphitheater gallery, and thence to the surface of the lava lake. This we found extremely irregular, presenting cones, mounds, plains, vast bridges of lava recently cooled, pits and caverns, and portions of considerable extent in a movable and agitated state. We walked over lava which, by some process, had been fractured into immensely large slabs, as though it had been contracted by cooling, or been heaved up irregularly by the semi-fluid mass below. In the fissures of this fractured lava, the slabs or blocks two feet below the surface, were red-hot. A walking-stick thrust down would be set on fire and flame instantly. “Passing over many masses of such lava, we ventured toward the more central part of the lake, and came near to a recent mound which had probably been raised on the cooling surface, after our arrival the day before. From the top of it flowed melted lava, which spread itself in waves to a considerable distance, one side or the other, all around. The masses thrown out in succession moved sluggishly, and as they flowed down the inclined plane, a crust was formed over them, which darkened and hardened, and became stationary, while the stream still moved on below it. The front of the mass, red-hot, passed along down, widening and expanding itself, and forcing its way through a net-work, as it were, of irregular filaments of iron, which the cooling process freely supplied. This motion of a flowing mass, whether smaller or larger, seen from the rim of the crater by night, gives the appearance of a fiery surf, or a rolling wave of fire, or the dancing along of an extended semicircular flame on the surface of the lake. When one wave has expended itself, or found its level, or otherwise become stationary, another succeeds and passes over it in like manner, and then another, sent out as it were, by the pulsations of the earth’s open artery, at the top of the mound. This shows how a mound, cone, pyramid, or mountain, can be gradually built of lava, and wide plains covered at its base with the same material.
