His fears were well grounded. As though he had planned it long before, as if the whole route of his flight had been preconceived, the black pony swung to the right as he came up on level ground. He cut across the intervening flat and, ears back, hindquarters scrooching far under his body as he changed his gait for the steep drop, he disappeared over the rim. Bayard cried aloud, the sorrel swung unbidden on the trail of the runaway and twenty yards behind stuck his fore feet stiffly out for the first leap down the rock-littered point. Unspeakable footing, that. _Malpais_ lumps, ranging from the size of an egg to some that weighed tons, were everywhere. Between them sparse grass grew, but in no place was there bare ground the size of a horse's hoof, and for every four lengths they traveled forward, they dropped toward the valley by one! Ears up now, the sorrel watched his footing anxiously, but the black pony, eyes rolling, put his whole vigor into the running, urged on to even greater efforts by the nearness of the pursuing animal. The fortune that goes with flying bronchos alone kept his feet beneath his body. Bayard's mouth was open and each time the shock of being thrown forward and down racked his body, the breath was beaten from him. He looked ahead, watching the footing at the bottom, leaving that over which they then passed to his horse, for the most critical moment in a run such as they took is when the horses strike level ground. Then they are apt to go end over end, tripped by the impetus that their rush downhill gives them. He knew that he could not overtake and turn Ann's pony with safety before they reached the bottom. He feared that to come abreast of him might drive the frantic beast to that last effort which would result in an immediate fall. Every instant was precious; every leap filled with potential disaster. The stallion left off pretense at clean running. He slipped and floundered and scrambled down the point; at times almost sitting on his haunches to keep the rush of his descent within safety and retain control of his balance. Slowly he drew closer to the other animal, crowding a bit to the left to be nearer, grunting with his straining, dividing his attention between preserving caution and making progress.
