The sheep raised a dust-cloud in the sandy wash where the road wound down, and Lucy hung back to let them get farther ahead. Gradually the tiny roar of pattering hoofs and the blended bleating and baaing died away. The dust-cloud, however, hung over the head of the ravine, and Lucy had to force Sarchedon through it. Sarchedon did not mind sand and dust, but he surely hated the smell of sheep. Lucy seldom put a spur to Sarchedon; still, she gave him a lash with her quirt, and then he went on obediently, if disgustedly. He carried his head like a horse that wondered why his mistress preferred to drive him down into an unpleasant hole when she might have been cutting the sweet, cool sage wind up on the slope. The wash, with its sand and clay walls, dropped into a gulch, and there was an end of green growths. The road led down over solid rock. Gradually the rims of the gorge rose, shutting out the light and the cliffs. It was a winding road and one not safe to tarry on in a stormy season. Lucy had seen boulders weighing a ton go booming down that gorge during one of the sudden fierce desert storms, when a torrent of water and mud and stone went plunging on to the river. The ride through here was short, though slow. Lucy always had time to adjust her faculties for the overpowering contrast these lower regions presented. Long before she reached the end of the gorge she heard the sullen thunder of the river. The river was low, too, for otherwise there would have been a deafening roar.
