On the arrival of Tom and his friends at the Indian's hut, Goosal told, in language which Professor Bumper could understand, the ancient legend of the buried city as he had had it from his grandfather.

"But is that all you know about it, Goosal?" asked the savant.

"No, Learned One. It is true most of what I have told you was told to me by my father and his father's father. But I—I myself—with these eyes, have looked upon the lost city."

"You have!" cried the professor, this time in English. "Where? When? Take us to it! How do you get here?"

"Through the cavern of the dead," was the answer when the questions were modified.

"Bless my diamond ring!" exclaimed Mr. Damon, when Professor Bumper translated the reply. "What does he mean?"

And then, after some talk, this information came out. Years before, when Goosal was a young man, he had been taken by his grandfather on a journey through the jungle. They stopped one day at the foot of a high mountain, and, clearing away the brush and stones at a certain place, an entrance to a great cavern was revealed. This, it appeared, was the Indian burial ground, and had been used for generations.

Goosal, though in fear and trembling, was lead through it, and came to another cavern, vaster than the first. And there he saw strange and wonderful sights, for it was the remains of a buried city, that had once been the home of a great and powerful tribe unlike the Indians—the ancient Mayas it would seem.

"Can you take us to this cavern?" asked the professor.

"Yes," answered Goosal. "I will lead to it those who saved the life of Tal—them and their friends. I will take you to the lost city!"
