Farther on we climbed up a high, broken piece of rock, and descended again by a low, narrow opening, through which we were obliged to crawl, and which, from its own closeness, and the heat and smoke of the torches, and the labour of crawling through it, was so hot that we were panting with exhaustion and thirst. This brought us to a rugged, perpendicular hole, three or four feet in diameter, with steps barely large enough for a foothold, worn in the rock. We descended with some difficulty, and at the foot came out upon a ledge of rock, which ran up on the right to a great height, while on the left was a deep, yawning chasm. A few rude logs were laid along the edge of this chasm, which, with a pole for a railing, served as a bridge, and, with the torchlight thrown into the abyss below, made a wild crossing-place; the passage then turned to the right, contracting to about three feet in height and the same in width, and descending rapidly. We were again obliged to betake ourselves to crawling, and again the heat became insufferable. Indeed, we went on with some apprehensions. To faint in one of those narrow passages, so far removed from a breath of air, would be almost to die there. As to carrying a man out, it was impossible for either of us to do more than drag himself along, and I believe that there could have been no help from the Indians. This passage continued fifty or sixty feet, when it doubled on itself, still contracted as before, and still rapidly descending. It then enlarged to a rather spacious cavern, and took a southwest direction, after which there was another perpendicular hole, leading, by means of a rude and rickety ladder, to a steep, low, crooked, and crawling passage, descending until it opened into a large broken chamber, at one end of which was a deep hole or basin of water. This account may not be perfectly accurate in all the details, but it is not exaggerated. Probably some of the turnings and windings, ascents and descents, are omitted; and the truest and most faithful description that could be given of it would be really the most extraordinary. The water was in a deep, stony basin, running under a shelf of overhanging rock, with a pole laid across on one side, over which the Indians leaned to dip it up with their calabashes; and this alone, if we had wanted other proof, was confirmation that the place had been used as a well.
