"Here is a map of the ruins as they exist to-day," said the Doctor. "You perceive that the general shape of the work is a square, and that there are altogether three squares, the smaller inside the greater."
The boys looked at the map, and indicated that they observed the outline of the temple.
"Well," continued Doctor Bronson, "the outer wall, which is not shown in the plan, is more than half a mile square; if you should undertake to walk around it you would have a promenade of nearly three miles.
"Outside the wall there is a wide ditch that was evidently of considerable depth when first made, but it is filled in many places with weeds and trees, and there is a forest of palm-trees between the outer wall and the body of the temple.
"The main entrance is by a causeway, which you see extending upward from the foot of the map. The whole length of this causeway, from its beginning beyond the outer wall to the entrance of the temple, is nearly two thousand feet, and more than half this distance is within the wall. The building itself, as you see it on the map, is oblong in shape, being eight hundred feet long by five hundred and ninety wide; it rises in three terraces to a central tower two hundred and fifty feet high, and there are four other towers at the corners of the inner temple that are each one hundred and fifty feet from the ground.
