"That fellow's no Injun," he called to his friend.
"Look!" Thursday was pointing to the saddle-back between two peaks at the head of the arroyo.
A girl on horseback had just come over the summit and stood silhouetted against the sky. Even in that moment while they watched her she realized for the first time her danger. She turned to fly, and she and her horse disappeared down the opposite slope. The Mescaleros swept up the hill toward her.
"They'll git her! They'll sure git her!" cried Billie, making for his horse.
The younger man ran limping to his cinnamon. At every step he winced, and again while his weight rested on the wounded foot as he dragged himself to the saddle. A dozen yards behind his companion he sent his horse splashing through the creek.
The cowponies, used to the heavy going in the hills, took the slope in short, quick plunges. Neither of the young men used the spur, for the chase might develop into a long one with stamina the deciding factor. The mesquite was heavy and the hill steep, but presently they struck a cattle run which led to the divide.
Two of the Apaches stopped at the summit for a shot at their pursuers, but neither of the young men wasted powder in answer. They knew that close-range work would prove far more deadly and that only a chance hit could serve them now.
From Billie, who had reached the crest first, came a cry of dismay. His partner, a moment later, knew the reason for it. One of the Apaches, racing across the valley below, was almost at the heels of the girl.
The cowpunchers flung their ponies down the sharp incline recklessly. The animals were sure-footed as mountain goats. Otherwise they could never have reached the valley right side up. It was a stretch of broken shale with much loose rubble. The soft sandstone farther along had eroded and there was a great deal of slack débris down which the horses slipped and slid, now on their haunches and again on all fours.
The valley stretched for a mile before them and terminated at a rock wall into which, no doubt, one or more cañons cut like sword clefts. The cowpunchers had picked mounts, but it was plain they could not overhaul the Apaches before the Indians captured the girl.
