"Good!" cried Mr. Damon, when this had been translated. "Now let Beecher try to play any more tricks on us! Ho! for the cavern and the lost city of Kurzon."

"And the idol of gold," said Tom Swift to himself. "I hope we can get it ahead of Beecher. Perhaps if I can help in that—Oh, well, here's hoping, that's all!" and a little smile curved his lips.

Greatly excited by the strange news, but maintaining as calm an air outwardly as possible, so as not to excite the Indians, Tom and his friends returned to camp to prepare for their trip. Goosal had said the cavern lay distant more than a two-days' journey into the jungle.

THE STORM

"Now," remarked Tom, once they were back again in their camp, "we must go about this trip to the cavern in a way that will cause no suspicion over there as to what our object is," and he nodded in the direction of the quarters of his rival.

"Do you mean to go off quietly?" asked Ned.

"Yes. And to keep the work going on here, at these shafts," put in the scientist, "so that if any of their spies happen to come here they will think we still believe the buried city to be just below us. To that end we must keep the Indians digging, though I am convinced now that it is useless."

Accordingly preparations were made for an expedition into the jungle under the leadership of Goosal. Tal had not sufficiently recovered from the jaguar wounds to go with the party, but the old man, in spite of his years, was hale and hearty and capable of withstanding hardships.
