"What's the matter, Tom?" for he had been awakened, and heard the crackle of the electrical discharge.

"I don't know," Tom answered. "But I shot something—or somebody!"

"Maybe some of Beecher's crowd," ventured his chum. But when they got their electric torches, and focused them on the inert, black object, it was found to be a bear which had come to nose about the camp for dainty morsels.

Bruin was quite dead, and as he was in prime condition there was a feast of bear meat at the following dinner. The white travelers found it rather too strong for their palates, but the Indians reveled in it.

It was shortly after noon the next day, when Goosal, after remarking that a storm seemed brewing, announced that they would be at the entrance to the cavern in another hour.

"Good!" cried Professor Bumper. "At last we are near the buried city."

"Don't be too sure," advised Mr. Damon, "We may be disappointed. Though I hope not for your sake, my dear Professor."

Goosal now took the lead, and the old Indian, traveling on foot, for he said he could better look for the old landmark that way than on the back of a mule, walked slowly along a rough cliff.

"Here, somewhere, is the entrance to the cavern," said the aged man. "It was many years ago that I was here—many years. But it seems as though yesterday. It is little changed."

Indeed little did change in that land of wonders. Only nature caused what alterations there were. The hand of man had long been absent.
