is difficult to form a conception, must have passed within two days' march of this city.
The extent along the river, as ascertained by monuments still found, is more than two miles. There is one monument on the opposite side of the river, at the distance of a mile, on the top of a mountain 2,000 feet high. Whether the city ever crossed the river, and extended to that monument, it is impossible to say. I believe not. At the rear is an unexplored forest, in which there may be ruins. There are no remains of palaces or private buildings, and the principal part is that which stands on the bank of the river, and may, perhaps, with propriety be called the Temple.
This temple is an oblong enclosure. The front or river wall extends in a right line north and south 624 feet, and is from sixty to ninety feet in height It is made of cut stones, from three to six feet in length, and a foot and a half in breadth. In many places the stones have been thrown down by bushes growing out of the crevices, and in one place there is a small opening, from which the ruins are sometimes called by the Indians Las Ventanas, or the windows. The other three sides consist of ranges of steps and pyramidal structures, rising from 30 to 140 feet in height on the slope. The whole line of survey is 2,866 feet, which, though gigantic and extraordinary for a ruined structure of the aborigines, that the reader's imagination may not mislead him, I consider it necessary to say, is not so large as the base of the great Pyramid of Ghizeh.
The engraving opposite gives the plan according to our survey, a reference to which will assist the reader to understand the description.
To begin on the right: Near the south-west corner of the river wall and the south wall is a recess, which was probably once occupied by a colossal monument fronting the water, no part of which is now visible; it may have fallen and been broken, and the fragments buried or washed away by the floods of the rainy season. Beyond are the remains of two small pyramidal structures, to the largest of which is attached a wall running along the right bank of the river: this appears to have been one of the principal walls of the city; and between the two pyramids there seems to have been a gateway or principal entrance from the water.
The south wall runs at right angles to the river, beginning with a range of steps about thirty feet high, and each step about eighteen inches square. At the south-east corner is a massive pyramidal structure, 120 feet high on the slope. On the right are other remains of terraces and pyramidal buildings; and here also was probably a gateway, by a passage about twenty feet wide, into a quadrangular
