‘The next avenue which I traversed, after cutting arrows on the stones under our feet, pointing to the mouth of the cave, was one that led us in a southerly direction for more than two miles. We then left it, and took another that led us east, then north, more than two miles farther; and at last, in our windings, were brought out by another avenue into the chief city again, after having traversed more than five miles through different avenues. We rested ourselves for a few minutes on some limestone strata near the centre of this gloomy area, and having refreshed ourselves, and trimmed our lamps, again took our departure through an avenue almost due north, and parallel with the avenue leading from the chief city to the mouth of the cave, which we continued for more than two miles, when we entered the second city. This is covered with one arch nearly two hundred feet high in the centre, and very similar to the chief city, except in the number of avenues leading from it, this having but two. We passed through it over a very considerable rise in the centre, and descended through an avenue bearing to the east about three hundred rods, when we came upon a third area, about one hundred feet square and fifty in height, which had a pure and delightful stream of water, issuing from the side of the wall, about thirty feet high, and which fell upon some broken stones, and was afterwards entirely lost to our view. After passing this beautiful sheet of water a few yards, we came to the end of this passage. ‘We then returned about one hundred yards, and entered an avenue (over a considerable mass of stone) to our right, which led us south, through an uncommonly black avenue, something more than a mile, when we ascended a very steep eminence, about sixty yards, which carried us within the walls of a fourth city, which is not inferior to the second city, having an arch that covers at least six acres. In this last avenue, the farther end of which must be at least four miles from the chief city, and ten from the mouth of the cave, are twenty large piles of saltpetre earth on one side of the avenue, and broken limestone heaped up on the other, evidently the work of human hands. I had expected, from the course of my needle, that this avenue would have carried us round to the chief city; but was sadly disappointed, when I found the end a few hundred yards from the fourth city, which caused us to retrace our steps; and not having been so particular in marking the different entrances as I ought, we were very much bewildered, and once completely lost for fifteen or twenty minutes.
