No one knows how old the ruins are.

No one knows how many distinct civilizations have held sway there, one, literally, on top of the other." "It is too hot up here to talk ancient history," said Frank, "and I'm hungry, too, but I'd like to know where you find any pyramids in Mexico." "The pyramid-temple of Cholulu," went on the delighted drummer, "is the largest and best known.

It makes the pyramids of Egypt look like thirty cents in comparison, for it is nearly fifteen hundred feet on each side and almost two hundred feet high.

Gizeh, the big Egyptian pyramid, is only 763 feet along the sides, but it has the Mexican one beaten in height, it being over five hundred feet high.

"No one knows," was the reply.
