Beads of sweat broke out on Jack's forehead as he listened. He bit his lips until they bled. Clenching his fingers until the nails sank into the palms of his hands, he cried warningly in his agony: "I wouldn't say no more, if I was you. Go—for God's sake, go!"
Dick slowly moved toward the mouth of the canon, still hesitating.
From the hillside a rifle-shot rang out. The ball struck Dick in the leg. He fell, and lay motionless.
Pulling his revolver, Jack stooped and ran under the overhanging ledge, peering about to see where the shot had come from. He raised his gun to fire, when a volley of rifle-shots rang through the canon, the bullets kicking up little spurts of dust about him and chipping edges off the rocks. Jack dropped on his knees and crept to his rifle, clipping his revolver back into his holster.
Crouching behind a rock with his rifle to his shoulder, he waited for the attackers to show themselves.
Experience on the plains taught them that the fight would be a slow one, unless the Apaches sought only to divert attention for the time being to cover their flight southward. After the one shot, which struck Dick, and the volley directed at Jack, not a rifle had been fired. Peering over the boulder, Jack could see nothing.
The Lava Beds danced before his eyes in the swelter of the glaring sunshine. Far off the snow-capped mountains mockingly reared their peaks into the intense blue of the heavens. Since the attackers were covered with alkali-dust from the long ride, a color which would merge into the desert floor when a man lay prone, detection of any movement was doubly difficult. Behind any rock and in any clump of sage-brush might lie an assailant.
Dick had fallen near the spring. He struggled back to consciousness, to find his left leg numb and useless. When the ball struck him he felt only a sharp pinch. His fainting was caused by a shock to his weakened body, but not from fear or pain. With the return to his senses came a horrible, burning thirst, and a horrible sinking sensation in the pit of his stomach. He lay breathing heavily until he got a grip on himself. Then he tore the bandanna handkerchief from his neck and bound up the wound, winding the bandage as tightly as his strength permitted to check the blood-flow.
"What is it?" asked Jack, over his shoulder.
"Indians—the 'Paches are out. I'm hit," gasped Dick. He crawled painfully and slowly to Jack's side, dragging his leg after him. He pulled with him his rifle, which he picked up as he passed from the spot where it had fallen in his first wild rush for water.
