During all these waiting days Venters, with the exception of the afternoon when he had built the gate in the gorge, had scarcely gone out of sight of camp and never out of hearing. His desire to explore Surprise Valley was keen, and on the morning after his long talk with the girl he took his rifle and, calling Ring, made a move to start. The girl lay back in a rude chair of boughs he had put together for her. She had been watching him, and when he picked up the gun and called the dog Venters thought she gave a nervous start.
"I'm only going to look over the valley," he said.
"Will you be gone long?"
"No," he replied, and started off. The incident set him thinking of his former impression that, after her recovery from fever, she did not seem at ease unless he was close at hand. It was fear of being alone, due, he concluded, most likely to her weakened condition. He must not leave her much alone.
As he strode down the sloping terrace, rabbits scampered before him, and the beautiful valley quail, as purple in color as the sage on the uplands, ran fleetly along the ground into the forest. It was pleasant under the trees, in the gold-flecked shade, with the whistle of quail and twittering of birds everywhere. Soon he had passed the limit of his former excursions and entered new territory. Here the woods began to show open glades and brooks running down from the slope, and presently he emerged from shade into the sunshine of a meadow. The shaking of the high grass told him of the running of animals, what species he could Dot tell, but from Ring's manifest desire to have a chase they were evidently some kind wilder than rabbits. Venters approached the willow and cottonwood belt that he had observed from the height of slope. He penetrated it to find a considerable stream of water and great half-submerged mounds of brush and sticks, and all about him were old and new gnawed circles at the base of the cottonwoods.
"Beaver!" he exclaimed. "By all that's lucky! The meadow's full of beaver! How did they ever get here?"
Beaver had not found a way into the valley by the trail of the cliff-dwellers, of that he was certain; and he began to have more than curiosity as to the outlet or inlet of the stream. When he passed some dead water, which he noted was held by a beaver dam, there was a current in the stream, and it flowed west. Following its course, he soon entered the oak forest again, and passed through to find himself before massed and jumbled ruins of cliff wall. There were tangled thickets of wild plum-trees and other thorny growths that made passage extremely laborsome. He found innumerable tracks of wildcats and foxes. Rustlings in the thick undergrowth told him of stealthy movements of these animals. At length his further advance appeared futile, for the reason that the stream disappeared in a split at the base of immense rocks over which he could not climb. To his relief he concluded that though beaver might work their way up the narrow chasm where the water rushed, it would be impossible for men to enter the valley there.
This western curve was the only part of the valley where the walls had been split asunder, and it was a wildly rough and inaccessible corner. Going back a little way, he leaped the stream and headed toward the southern wall. Once out of the oaks he found again the low terrace of aspens, and above that the wide, open terrace fringed by silver spruces. This side of the valley contained the wind or water worn caves. As he pressed on, keeping to the upper terrace, cave after cave opened out of the cliff; now a large one, now a small one. Then yawned, quite suddenly and wonderfully above him, the great cavern of the cliff-dwellers.
It was still a goodly distance, and he tried to imagine, if it appeared so huge from where he stood, what it would be when he got there. He climbed the terrace and then faced a long, gradual ascent of weathered rock and dust, which made climbing too difficult for attention to anything else. At length he entered a zone of shade, and looked up. He stood just within the hollow of a cavern so immense that he had no conception of its real dimensions. The curved roof, stained by ages of leakage, with buff and black and rust-colored streaks, swept up and loomed higher and seemed to soar to the rim of the cliff. Here again was a magnificent arch, such as formed the grand gateway to the valley, only in this instance it formed the dome of a cave instead of the span of a bridge.
Venters passed onward and upward. The stones he dislodged rolled down with strange, hollow crack and roar. He had climbed a hundred rods inward, and yet he had not reached the base of the shelf where the cliff-dwellings rested, a long half-circle of connected stone house, with little dark holes that he had fancied were eyes. At length he gained the base of the shelf, and here found steps cut in the rock. These facilitated climbing, and as he went up he thought how easily this vanished race of men might once have held that stronghold against an army. There was only one possible place to ascend, and this was narrow and steep.
Venters had visited cliff-dwellings before, and they had been in ruins, and of no great character or size but this place was of proportions that stunned him, and it had not been desecrated by the hand of man, nor had it been crumbled by the hand of time. It was a stupendous tomb. It had been a city. It was just as it had been left by its builders. The little houses were there, the smoke-blackened stains of fires, the pieces of pottery scattered about cold hearths, the stone hatchets; and stone pestles and mealing-stones lay beside round holes polished by years of grinding maize--lay there as if they had been carelessly dropped yesterday. But the cliff-dwellers were gone!
