Thirty feet above the water his strength was almost outspent, but he struggled to raise himself one more time, and then another. To pause meant to slip back and perish. Another upward heave. The rope here bent in over the rounding cliff. Hardly could he force his fingers between it and the rock. Yet if only he could get his knee up on the sharp slope! He heaved again, his face purple with exertion, the veins swelling out on his forehead as if about to burst.

At last! his knee was up and braced against the rock. Another desperate clutch at the rope––another heave––still another. The cliff edge was rounding back. Every upward hitch was easier than the one before. Now he was scrambling up on toes and knees; now he could rise to his feet.

The line led across a waterworn ledge and downward. Ashton peered over, and saw the senseless body of Blake wedged against the other side of the ledge. About it, close below the arms, the line was knotted fast.

Ashton stared wonderingly at the still, white face of the unconscious man. It was covered with cold sweat. A peculiar twist in the sprawling left leg caught his attention. He looked––and understood. Panting with exertion, he staggered down the ledges of the lower side of the barrier to where the river burst furiously out of the mouth of the tunnel.

Hurled by that mad torrent from the darkness of the 330 gorged cavern straight upon a line of rocks, all Blake’s strength and quickness had not enabled him to save himself from injury. Yet he had crept up those rough ledges, dragging his shattered leg. Atrocious as must have been his agony, he had crept all the way to the top, had written the note, and flung down the rope to rescue his companion.

There was no vessel in which Ashton could carry water. He had no hat, his boots were full of holes, he must use his hands in scrambling back up the ledges. He stripped off his tattered flannel shirt, dipped it in a swirling eddy, and started back as fast as he could climb.

Blake still lay unconscious. Ashton straightened out the twisted leg, and knelt to bathe the big white face with an end of the dripping garment. After a time the eyelids of the prostrate man fluttered and lifted, and the pale blue eyes stared upward with returning consciousness.

“I’m here!” cried Ashton. “Do you see? You saved me!”

“Colt’s gone,” muttered Blake. “But cartridges––fire.”

“You mean, fire the cartridges to let them know where we are? How can I do it without the revolver?”
