The stones in this foundation and wall, as in the walls still higher, are many of them of a most enormous size; at the west and south-west corner especially, they are almost incredibly large. Where all were so large, we did not think it worth while to measure very many. In one row, and that one at some distance from the ground, are three stones which we measured, and made them about seventy feet long each, and about fifteen feet wide. The thickness we could not certainly tell, but we inferred it to be about fourteen feet. These stones are much of the same shape and appearance, they are precisely like one which lies nearly cut out in the quarry, which we were, from its position, enabled to measure accurately. It was seventy feet six inches long, fourteen feet two inches thick, and seventeen feet nine inches wide at one end, and thirteen feet eight inches at the other. We were at once struck with its perfect likeness to the three stones in the wall; all of them were wider at one end than the other. I suppose that these four large stones, the three in the wall and the one in the quarry, were originally intended, either for obelisks, pillars, images, or some such thing; that their being now in the wall, is owing to a subsequent arrangement, when the place was converted into a fortress, and those stupendous outside walls put up, which now fill us with wonder. Under these three immense stones are seven others, which almost equal those above them in width; their thickness also, judging from what is seen at the corner of the building, does not much fall short of a due proportion. In truth, they are upon a most gigantic scale. This row extends along the south-west side nearly one hundred yards, forming a most solid foundation, ten or twelve feet high, which, however, on this side, is not built upon out to the edge, the wall going up about twenty feet inward. The above-mentioned are the largest stones I saw in these ruins; but many others are enormous, and, as a general thing, they are very large. As a sample, I measured one of a large row of stones at the south-east corner of the most perfect building now standing, (it was a corner stone, which enabled me to ascertain the thickness,) and found it to be twenty-eight feet long, six feet six inches wide, and four feet six inches thick. I was not at all certain that I might not, on measuring, have found many still larger.
