Then, as he looked, something ran out upon the edge of the great rock beside the cataract, and he clutched at his own breast to hold back what he thought must burst forth in words.  For he knew—­as surely as he knew that Wabi was at his side—­that he was looking upon John Ball!  For a moment the strange creature crouched where the stub had been, and when he saw that it was gone he stood erect, and a quavering, pitiful cry echoed softly through the chasm.  And as he stood there motionless the watchers saw that the mad hunter was an old man, tall and thin, but as straight as a sapling, and that his head and breast were hidden in shaggy beard and hair.  In his hands he carried a gun—­the gun that had fired the golden bullets—­and even at that distance those who were peering from the gloom of the cabin saw that it was a long barreled weapon similar to those they had found in the other old cabin, along with the skeletons of the Frenchmen who had died in the fatal knife duel.

In breathless suspense the three waited, not a muscle of their bodies moving.  Again the old man leaned over the edge of the rock, and his voice came to them in a moaning, sobbing appeal, and after a little he stretched out his arms, still crying softly, as if beseeching help from some one below.  The spectacle gripped at Rod’s soul.  A hot film came into his eyes and there was an odd little tremble in his throat.  The Indians were looking with dark, staring eyes.  To them this was another unusual incident of the wilderness.  But to Rod it was the white man’s soul crying out to his own.  The old man’s outstretched arms seemed reaching to him, the sobbing voice, filled with its pathos, its despair, its hopeless loneliness, seemed a supplication for him to come forth, to reach up his own arms, to respond to this lost soul of the solitudes.  With a little cry Rod darted between his companions.  He threw off his cap and lifted his white face to the startled creature on the rock, and as he advanced step by step, reaching out his hands in friendship, he called softly a name: 

“John Ball, John Ball, John Ball!”

In an instant the mad hunter had straightened himself, half turned to flee.

“John Ball!  Hello, John Ball—­John Ball—­”

In his earnestness Rod was almost sobbing the name.  He forgot everything now, everything but that lonely figure on the rock, and he drew nearer and nearer, gently calling the name, until the mad hunter dropped on his knees and, crumpled in his long beard and gray lynx skin, looked down upon Rod and sent back a low moaning, answering cry.

“John Ball!  John Ball, is that you?”

Rod stopped, with the madman forty feet above him, and something seemed choking back the very breath in him when he saw the strange look that had come into the old man’s eyes.

“John Ball—­”

The wild eyes above shifted for a moment.  They caught a glimpse of two heads thrust from the door of the old cabin, and the madman sprang to his feet.  For a breath he stood on the edge of the rock, then with a cry he leaped with the fierce agility of an animal far out into the swirl of the cataract!  For an instant he was visible in the downward plunge of the water.  Another instant and with a heavy splash he disappeared in the deep pool under the fall!
