Beyond this portion of the city the houses were scattered, the outlying buildings were more or less patched and out of repair and were very evidently the abode of the poorer classes, although the inhabitants I saw, and who retreated the instant they saw me, were exactly like all the others as far as I could see, both in dress and feature. Passing these huts, I crossed the smooth green field, which I now saw was a perfect landing place for the plane. Tethered to stakes and grazing on the grass were a number of animals which, as I first noticed them, I had taken for goats and cattle. But now I discovered that they were all deer and tapirs. It was a great surprise to see these animals domesticated but, after all, it was not remarkable, for I should have known, had I stopped to give the matter thought, that goats, sheep and cattle were unknown to the aboriginal Americans and that this city and its people, who had never been visited and had never communicated with other races, would of necessity be without these well known animals. Moreover, I knew that the Mayas were supposed to have used tapirs as beasts of burden, and while I was standing there watching the creatures a man approached riding astride a big tapir and driving a second one loaded with bags of charcoal and garden produce. Here then was a partial solution of the manner by which these weak, dwarfed people built their stone houses. For with the powerful elephant-like tapirs—and I noticed all were the giant Baird’s tapir which reaches a weight of seven or eight hundred pounds—they could easily haul the blocks of stone from a quarry and by means of tackle and inclined planes, could readily hoist the stones to the tops of the walls. I had now reached the base of the pyramid and found it a massive structure of the same flinty stone as the other buildings. Running from base to summit was a spiral path or stairway and instantly I knew that it was a sacrificial pyramid exactly like those used by the Aztecs and on which unfortunate beings were killed and sacrificed. This discovery still further confirmed my suspicions that these people were either of Aztec or Maya blood or had been influenced by those races. Filled with curiosity to see the altar on the summit I started up the sloping stairs. I was at first doubtful if my companion would permit this, for the structure was sacred and doubtless only priests of the highest order were permitted upon it. Evidently, however, my guide thought that such a supernatural being or god as myself had every right to invade the most sacred places, and he offered no objection, but prostrated himself at the base of the pyramid as I ascended.
