"Whar I'm goin' to take ye," he said, "lots of people have bin before. It's most cleaned out o' relics, I reckin; but thar, see thar!" He turned suddenly, and seized the Professor's arm. "Come here, a few rods further," he went on, pointing at the same time, as he waded up the stream to the opposite side of the cliff.

The village that the boys had first seen was nothing to that which now was plain in sight, under a great beetling brow of stone, that thrust out overhead a hundred feet or so into the cañon. It was fully one thousand feet from where they stood straight up to the ledge upon which this village stood. Sheer and straight it was, without a fissure or the chance for a foothold below, and the overhanging mass above marked it at once as inaccessible. The sides of the houses could be seen as they stood there almost intact, the ends of the roof-beams were plain in sight even to the naked eye, and through the field-glass a pile of pottery could be made out standing near the entrance to one of the larger dwellings.

The Professor gazed in astonishment. "It looks as if it were built yesterday," he said.

"How did they get up there?" inquired Carter, as he plashed up alongside.

"That's more than I can tell you," answered the Professor, slowly. "Major Evans told me of this village, but probably the old method of going there has been destroyed by time. In my opinion, no human foot has been there in the last thousand years or more."

"I'd like to see what it's like," said George, looking up, with his glass to his eye. "I'd like to get in there."

The Professor sighed. "Science would give a great deal to have you," he replied; "but come on; we must hurry to reach the small one over yonder." He pointed again to the ruins on the other side.

By careful climbing and careful stretching from point to point they at last reached the smaller ledge and entered through the narrow opening cut in the solid rock. It was as Coleman had reported; there was evidence of many visitations before them. Under the thick stifling dust they found nothing but some crumbling brick-work, bits of rough earthen jars, and a sandal made of straw.

Professor Jensen was outspoken in his disappointment. It was evident that the destroying power of nature besides that of man had been at work long, long before him.

The village, unlike the one across the chasm, was in a very exposed position, and rain and water had helped to work destruction; but over there in front of them and some hundred feet above their heads was the tantalizing fortress which they could not reach. What treasures it possessed! The Professor sighed; a long trip of three or four days had been next to fruitless.
