Next day they reached the mountain where the Cave Dwellers lived, and found that the Navahos, to the number of over two hundred, had pitched their camp in front of it. But they had been able to do nothing toward the rescue of their chief, for the face of the mountain was a perpendicular cliff, at the foot of which a stream flowed.

Buffalo Bill crossed the stream and rode forward to reconnoiter the position, accompanied by several of the Indians. They had not gone more than a hundred yards along the foot of the cliff when a great stone came bounding down from above, striking the ground a few yards in front of Buffalo Bill’s horse and breaking into fragments.

At the same moment a shrill yell was heard from the cliff above, and, looking up, they saw a number of the Cave Dwellers on a ledge two hundred feet above them, with their bows bent threateningly.

“Back, all of you!” shouted Buffalo Bill. “Their arrows may be poisoned.”

Seeing that the party retreated quickly, the savages did not shoot.

When they had got out of range, Buffalo Bill called a council of war, but found that nobody had any useful suggestions to offer. Then he mounted his horse and rode along the bank of the river farthest from the Cave Dwellers to get a good view of the cliff. He saw that there were three or four openings in the solid rock on the level of the ledge on which the Indians were posted.

He was astonished to notice that above these openings the cliff, which was in this place quite perpendicular, was covered with many strange sculptured figures, some of which still retained the color with which they had been painted in times long past.

Evidently the Cave Dwellers had not always been the degraded savages they were at present, or, more probably, a higher race had formerly occupied the caves and made these sculptures.

“Now, Eagle Eye,” said the border king, as the Navaho brave came up to his side and watched the cliff with him, “we have to see how this place can be climbed.”

The Navaho shook his head sorrowfully.
