"Yes, those are the things we want," agreed Tom, with a glance at his chum. "That is—some of them. But does your wife's grandfather talk our language?"

"No, but I can tell you what he says."

By this time the old man, led by "Mrs. Tal"—as the young men called the wife of the Indian they had helped—entered the hut. He seemed nervous and shy, and glanced from Tom and Ned to his grandson-in-law, as the latter talked rapidly in the Indian dialect. Then Goosal made answer, but what it was all about the boys could not tell.

"Goosal say," translated Tal, "that he know a story of a very old city away down under ground."

"Tell us about it!" urged Tom eagerly.

But a difficulty very soon developed. Tal's intentions were good, but he was not equal to the task of translating. Nor was the understanding of Tom and Ned of Spanish quite up to the mark.

"Say, this is too much for me!" exclaimed Tom. "We are losing the most valuable part of this by not understanding what Goosal says, and what Tal translates."

"What can we do?" asked Ned.

"Get the professor here as soon as possible. He can manage this dialect, and he'll get the information at first hand. If Goosal can tell where to begin excavating for the city he ought to tell the professor, not us."

"That's right," agreed Ned. "We'll bring the professor here as soon as we can."
