Still Lane held on with a vise-like clutch.

Suddenly he seemed to feel some mighty propelling force under him; he rose high with the stern of the boat. Then the bow pitched down into a yawning hole. A long instant he and the boat slid down a glancing fall—then thunderous roar—furious contending wrestle—cold, yellow, flying spray—icy, immersing, enveloping blackness!

A giant tore his hands from the boat. He whirled round and round as he sank. A languid softness stole over him. He saw the smile of his mother, the schoolmate of his boyhood, the old attic where he played on rainy days, and the spotted cows in the pasture and the running brook. He saw himself a tall young man, favorite of all, winning his way in life that was bright.

Then terrible blows of his heart hammered at his ribs, throbs of mighty pain burst his brain; great constrictions of his throat choked him. He began fighting the encompassing waters with frenzied strength. Up and up he fought his way to see at last the light, to gasp at the air. But the flood sucked at him, a weight pulled at his feet. As he went down again something hard struck him. With the last instinctive desperate love of life in his action he flung out his hand and grasped the saving thing. It was the boat. He hooked his elbow over the gunwale. Then darkness filmed over his eyes and he seemed to feel himself whirling round and round, round and round. A long time, seemingly, he whirled, while the darkness before his eyes gave way to smoky light, his dead ears awoke to confused blur of sound. But the weight on his numb legs did not lessen.

All at once the boat grated on a rock, and his knees struck. He lay there holding on while life and sense seemed to return. Something black and awful retreated. Then the rush and roar of the rapids was again about him. He saw that he had drifted into a back eddy behind the ledge of rock, and had whirled slowly round and round with a miscellaneous collection of driftwood.

Lane steadied himself on the slippery ledge and got to his feet. The boat was half full of water, out of which Swarm's ghastly face protruded. By dint of great effort Lane pulled it sideways on the ledge, and turned most of the water out.

Swann lay limp and sodden. But for his eyes he would have appeared dead, and they shone with a conscious light of terror, of passionate appeal and hope, the look with which a man prayed for his life. Presently his lips moved imperceptibly. "Save me! for God's sake, save me!"

Shuddering emotion that had the shock of electricity shook Lane. In his ears again rang the sullen, hollow, reverberating boom of the flood. Here was the man who had done most to harm him, begging to be saved. Swann, poor wretch, was afraid to die; he feared the unknown; he had a terror of that seething turmoil of waters; he could not face the end of that cold ride. Why?

"Fool!" Lane cried, glaring wildly about him. Was it another dream? Unreality swayed him again. He heard the roar, he saw the splitting white-crested waves, the clouds of yellow vapor. He beat his numb legs and shook himself like a savage dog. Then he made a discovery—in some way he could not account for, the oars had remained in the boat. They had been loose in their oar-locks.

Questions formed in Lane's mind, questions that seemed put by a dawning significance. Why had he heard the cry for help? Why had he found the boat? Why had the drowning man proved to be one of two men on earth he hated, one of the two men whom he wanted to kill? Why had he drifted into the rapids? Why had he come safely through a vortex of death? Why had Swann's lips formed that prayer? Why had the oars remained in the boat?
