a beam of wood; of what species we did not know, but our guide said it was of the sapote-tree. It was so hard that, on being struck, it rang like metal, and perfectly sound, without a worm-hole or other symptom of decay. The surface was smooth and even, and from a very close examination we were of the opinion that it must have been trimmed with an instrument of metal.
The opening under this doorway was what the alcalde had intended as the mouth of the cave that led to Palenque, and which, by-the-way, he had told us was so completely buried in El Monte that it would require two days digging and clearing to reach it. Our guide laughed at the ignorance prevailing in the village in regard to the difficulty of reaching it, but stoutly maintained the story that it led to Palenque. We could not prevail on him to enter it. A short cut to Palenque was exactly what we wanted. I took off my coat, and, lying down on my breast, began to crawl under. When I had advanced about half the length of my body, I heard a hideous hissing noise, and starting back, saw a pair of small eyes, which in the darkness shone like balls of fire. The precise portion of time that I employed in backing out is not worth mentioning. My companions had heard the noise, and the guide said it was "un tigre." I thought it was a wildcat; but, whatever it was, we determined to have a shot at it. We took it for granted that the animal would dash past us, and in a few moments our guns and pistols, swords and machetes, were ready: taking our positions, Pawling, standing close against the wall, thrust under a long pole, and with a horrible noise out fluttered a huge turkey-buzzard, which flapped itself through the building and took refuge in another chamber.
This peril over, I renewed the attempt, and holding a candle before me, quickly discovered the whole extent of the cave that led to Palenque. It was a chamber corresponding with the dimensions given of the outer walls. The floor was encumbered with rubbish two or three feet deep, the walls were covered with stuccoed figures, among which that of a monkey was conspicuous, and against the back wall, among curious and interesting ornaments, were two figures of men in profile, with their faces toward each other, well drawn and as large as life, but the feet concealed by the rubbish on the floor. Mr. Catherwood crawled in to make a drawing of them, but, on account of the smoke from the candles, the closeness, and excessive heat, it was impossible to remain long enough. In general appearance and character they were the same as we afterward saw carved on stone at Palenque.
By means of a tree growing close against the wall of this building, I climbed to the top, and saw another edifice very near and on the top
