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! Dust! They were dust on the floor or at the foot of the shelf, and their habitations and utensils endured. Venters felt the sublimity of that marvelous vaulted arch, and it seemed to gleam with a glory of something that was gone. How many years had passed since the cliff-dwellers gazed out across the beautiful valley as he was gazing now? How long had it been since women ground grain in those polished holes? What time had rolled by since men of an unknown race lived, loved, fought, and died there? Had an enemy destroyed them? Had disease destroyed them, or only that greatest destroyer—time? Venters saw a long line of blood-red hands painted low down upon the yellow roof of stone. Here was strange portent, if not an answer to his queries. The place oppressed him. It was light, but full of a transparent gloom. It smelled of dust and musty stone, of age and disuse. It was sad. It was solemn. It had the look of a place where silence had become master and was now irrevocable and terrible and could not be broken. Yet, at the moment, from high up in the carved crevices of the arch, floated down the low, strange wail of wind—a knell indeed for all that had gone.
