Wait until I come back," he said.
Without another word he plunged into the pool. Minute after minute passed, and he did not reappear. Rod was conscious of a nervous chill creeping into his blood. But Mukoki was chuckling confidently.
"Found heem!" he replied in response to the white youth's inquiring look.
As he spoke Wabigoon came up out of the pool like a great fish. Rod helped him upon the rocks.
"We're two bright ones, we are, Muky!" he exclaimed, as soon as he gained his breath. "Just behind the fall I ran up against the wall of rock we found when we were hunting for John Ball, stood on my feet, and—" he swung his arms suggestively—"there I was, head and shoulders out of water, looking into a hole as big as a house!"
"Dive easy!" warned the old pathfinder, turning to Rod. "Bump head on rock—swush!"
"We won't have to dive," continued Wabi. "The water directly under the fall of the stream isn't more than four feet deep. If we wade into it from over there we can make it easy."
Taking his waterproof bundle the young Indian slipped into the pool close up against the wall of rock that formed the foundation of the upper chasm and plunged straight into the tumbling cataract. Mukoki followed close behind and preparing himself with a long breath Rod hurried into this new experience. For a moment he was conscious of a smothering weight upon him and a thunderous roaring in his ears, and he was borne irresistibly down. There was still air in his lungs when he found himself safely through the deluge so he knew that its passage had taken him only a brief but thrilling instant. For a time he could see nothing. Then he made out a dark form drawing itself up out of the water. Beyond that there lay a chaos of midnight blackness, and he knew that his eyes were staring into the depths of a great cavern!
Gripping the edge of the rock ledge he dragged himself up as both Wabigoon and Mukoki had done, and found his feet upon a soft floor of sand. Suddenly he felt a hand clutch his arm. A half-shout, rising faintly above the wash of the cataract, sounded in his ear.
"Look!"
He wiped the water from his eyes and gazed ahead of him. For a moment he saw nothing. Then, so faintly that at first it appeared no larger than a star, he caught the faint glimmer of a light. As he looked it became more and more distinct, and to his astonishment he saw that it was slowly rising, like a huge will-o'-the-wisp that had suddenly risen from the floor of the cavern to float off into the utter blackness of space above. And even as he stared, gripping Wabi's arm in his excitement, the strange light began to descend, and quickly disappeared!
The two boys saw Mukoki slip off into the gloom, and without questioning his motive they followed close behind. As they progressed the sound of the fall came more and more faintly to their ears. A blackness deeper than the gloom of the darkest night environed them, and the three now held to one another's arms. Rod understood why his companions lighted no torches. Somewhere ahead of them was another light, carried by the mad hunter. His blood thrilled with excitement. Where would John Ball lead them?
Suddenly he became conscious that they were no longer walking on a level floor of sand but that they were ascending, as the light had done. Mukoki stopped and for a full minute they stood and listened. The tumult of the fall came to them in a far, subdued murmur. Beyond that there was not the breath of a sound in the strange world of gloom about them. They were about to start on again when something held them, a whispering, sobbing echo, and Rod's heart seemed to stop its beating. It died away slowly, and a weird stillness fell after it. Then came a low moaning cry, a cry that was human in its agony, and yet which had in it something so near the savage that even Wabigoon found himself trembling as he strained in futile effort to pierce the impenetrable gloom ahead. Before the cry had lost itself in the distances of the cavern Mukoki was leading them on again.
Step by step they followed in the path taken by the strange light. Rod knew that they were climbing a hill of sand, and that just beyond it they would see the light again, but he was not prepared for the startling suddenness with which the next change came. As if a black curtain had dropped from before their eyes the three adventurers beheld a scene that halted them in their tracks. A hundred paces away a huge pitch-pine torch a yard in length was burning in the sand, and crouching in the red glow of this, his arms stretched out as if in the supplication of a strange prayer, was John Ball! Just beyond him was the gleam of water, inky-black in the weird flickerings of the torch, and toward this John Ball reached out in his grief. His voice came up softly to the three watchers now, so low that even in the vast silence of the cavern it could barely be heard. To Roderick Drew it was as if the strange creature below him was sobbing like a heart-broken child, and he whispered in Wabigoon's ear. Then, foot by foot, so gently that his moccasined feet made no sound, he approached the madman.
Half-way to him he paused.
"Hello, John Ball!" he called softly.
The faint light of the torch was falling upon him, and he advanced another step. The murmuring of the wild man ceased, but he made no movement. He still knelt in his rigid posture, his arms stretched toward the black chaos beyond him. Rod came very close to him before he spoke again.
"Is that you, John Ball?"
Slowly the kneeling figure turned, and once more Rod saw in those wild eyes, gleaming brightly now in the torch-light, the softer, thrilling glow of recognition and returning reason. He reached out his own arms and advanced boldly, calling John Ball's name, and the madman made no retreat but crouched lower in the sand, strange, soft sounds again falling from his lips. Rod had come within half a dozen feet of him when he sprang up with the quickness of a cat, and with a wailing cry plunged waist deep into the water. With his arms stretched entreatingly into the mysterious world beyond the torch-light he turned his face to the white youth, and Rod knew that he was trying as best he could to tell him something.
"What is it, John Ball?"
He went to the edge of the black water and waded out until it rose to his knees, his eyes staring into the blackness.
"What is it?"
He, too, pointed with one arm, and the madman gave an excited gesture. Then he placed his hands funnel-shaped to his mouth, as Rod had often seen Wabi and Mukoki do when calling moose, and there burst from him a far-reaching cry, and Rod's heart gave a sudden bound as he listened, for the cry was that of a woman's name!
"Dol—o—res-s-s-s—Dol—o—res-s-s-s—"
The cry died away in distant murmuring echoes, and with an answering cry Rod shouted forth the name which he fancied John Ball had spoken.
"Dolores! Dolores! Dolores!"
There came a sudden leaping plunge, and John Ball was at his feet, clasping him about the knees, and sobbing again and again that name—Dolores. Rod put his arms about the old man's shoulders, and the gray, shaggy head fell against him. The sobbing voice grew lower, the weight of the head greater, and after a little Rod called loudly for Mukoki and Wabigoon, for there was no longer movement or sound from the form at his feet, and he knew that something had happened to John Ball. The two Indians were quickly at his side, and together they carried the unconscious form of Ball within the circle of torch-light. The old man's eyes were closed, his claw-like fingers were clenched fiercely upon his breast, and not until Mukoki placed a hand over his heart did the three know that he was still breathing.
"Now is our time to get him to camp," said Wabi. "Lead the way with the torch, Rod!"
There was not much weight to John Ball, and the two Indians carried him easily. At the fall the rubber blanket was wound about his head and the adventurers plunged under the cataract
