On and on they wandered to the wild jumble of massed and broken fragments of cliff at the west end of the valley. The roar of the disappearing stream dinned in their ears. Into this maze of rocks they threaded a tortuous way, climbing, descending, halting to gather wild plums and great lavender lilies, and going on at the will of fancy. Idle and keen perceptions guided them equally. “Oh, let us climb there!” cried Bess, pointing upward to a small space of terrace left green and shady between huge abutments of broken cliff. And they climbed to the nook and rested and looked out across the valley to the curling column of blue smoke from their campfire. But the cool shade and the rich grass and the fine view were not what they had climbed for. They could not have told, although whatever had drawn them was well-satisfying. Light, sure-footed as a mountain goat, Bess pattered down at Venters’s heels; and they went on, calling the dogs, eyes dreamy and wide, listening to the wind and the bees and the crickets and the birds. Part of the time Ring and Whitie led the way, then Venters, then Bess; and the direction was not an object. They left the sun-streaked shade of the oaks, brushed the long grass of the meadows, entered the green and fragrant swaying willows, to stop, at length, under the huge old cottonwoods where the beavers were busy. Here they rested and watched. A dam of brush and logs and mud and stones backed the stream into a little lake. The round, rough beaver houses projected from the water. Like the rabbits, the beavers had become shy. Gradually, however, as Venters and Bess knelt low, holding the dogs, the beavers emerged to swim with logs and gnaw at cottonwoods and pat mud walls with their paddle-like tails, and, glossy and shiny in the sun, to go on with their strange, persistent industry. They were the builders. The lake was a mud-hole, and the immediate environment a scarred and dead region, but it was a wonderful home of wonderful animals. “Look at that one—he puddles in the mud,” said Bess. “And there! See him dive! Hear them gnawing! I’d think they’d break their teeth. How’s it they can stay out of the water and under the water?” And she laughed. Then Venters and Bess wandered farther, and, perhaps not all unconsciously this time, wended their slow steps to the cave of the cliff-dwellers, where she liked best to go.
