"Sh-h-h-h-h!"

"What is it?"

"I thought I heard a sound!" breathed Rod. "Did you hear it?"

"No."

The two listened. There was an awesome silence in the chasm now, broken only by the distant murmur of running water, a strange, chilling stillness in which the young hunters could hear the excited beating of their own hearts. To Roderick the minutes passed like so many hours. His ears were keyed to the highest tension of expectancy, his eyes stared into the gloom beyond them until they ached with his efforts to see. At every instant he expected to hear again that terrible scream, this time very near, and he prepared himself to meet it. But the seconds passed, and then the minutes, and still there came no quick running of mad footsteps, no repetition of the cry. Had the madman turned the other way? Was he plunging deeper into the blackness of this mysterious world of his between the mountains?

"I guess I was mistaken," he whispered softly to Wabigoon. "Shall we get out our blankets?"

"We might as well make ourselves comfortable," replied the young Indian. "You sit here, and listen while I undo the pack."

He went noiselessly to Mukoki, who was leaning against the pack, and Rod could hear them fumbling at the straps on the bundle. After a little Wabi returned and the two boys spread out their blankets beside the rock upon which they had been sitting. But there was no thought of sleep in the mind of either, though both were dead tired from their long day's work. They sat closer together, shoulder touching shoulder, and unknown to his companion Roderick drew his revolver, cocked it silently and placed it where he could feel the cold touch of its steel between his fingers. He knew that he was the only one of the three who fully realized the horror of their situation.

Mukoki's mind, simple in its reasoning of things that did not belong to the wilderness, had accepted the assurances and explanations of Rod and Wabigoon. Wabi, half-bred in the wild, felt alarm only in the sense of physical peril. It was different with the white youth. What is there in civilization that sends the chill of terror to one's heart more quickly than the presence of a human being who has gone mad? And this madman was at large! At that very instant he might be listening to their breathing and their whispered words half a dozen feet away; any moment might see the blackness take form and the terrible thing hurl itself at their throats. Rod, unlike Wabigoon, knew that the powers of this strange creature of the chasm were greater than their own, that it could travel with the swiftness and silence of an animal through the darkness, that perhaps it could smell them and feel their presence as it passed on its way to the plain. He was anxious now to hear the cry again. What was the meaning of this silence? Was the madman already conscious of their presence? Was he creeping upon them at that moment, as still as the black shadows that shut in their vision? His mind was working in such vivid imaginings that he was startled when Wabi prodded him gently in the side.

"Look over there—across the chasm," he whispered. "See that glow on the mountain wall?"

"The moon!" replied Rod.

"Yes. I've been watching it, and it's creeping down and down. The moon is going to swing across this break in the mountains. In fifteen minutes we shall be able to see."

"It won't swing across so much as it will come up in line with us," replied Rod. "Watch how that light is lengthening! We shall be able to see for several hours."

He started to rise to his feet but fell back with an astonished cry. For a third time there came the mad hunter's scream, this time far above and beyond them, floating down from the distance of the moon-lit plain!

"He passed us!" exclaimed Wabi. "He passed us—and we didn't hear him!" He leaped to his feet and his voice rose excitedly until it rang in a hundred echoes between the chasm walls. "He passed us, and we didn't hear him!"

Mukoki's voice came strangely from out of the gloom.

"No man do that! No man—no man—"

"Hush!" commanded Rod. "Now is our time, boys! Quick, get everything to the creek. He's half a mile out on the plain and we can get away before he comes back. I'd rather risk a few rocks than another one of his golden bullets!"

"So had I!" cried Wabi.

As if their lives depended on their exertions the three set to work. Mukoki staggered ahead over the rocks with his burden while the boys followed with the light canoe and the remaining pack. Their previous experiences in the chasm had taught them where to approach the stream, and ten minutes later they were at its side. Without a moment's hesitation Mukoki dropped his pack and plunged in. The edge of the moon was just appearing over the southern mountain wall and by its light Rod and Wabigoon could see that the water of the creek was rushing with great swiftness as high as the old warrior's knees.

"No ver' deep," said the Indian. "Rocks—"

"I followed this creek for half a dozen miles and its bottom is as smooth as a floor!" interrupted Rod. "There's no danger of rocks for that distance!"

He made no effort now to suppress the pleasure which he felt at the escape from their unpleasant situation. Mukoki steadied the canoe as it was placed in the water, and was the last to climb into it, taking his usual position in the stern where he could use to best advantage the powerful sweeps of his paddle. In an instant the swift current of the little stream caught the birch bark and carried it along with remarkable speed. After several futile strokes of his paddle Wabi settled back upon his heels.

"It's all up to you, Muky," he called softly. "I can't do a thing from the bow. The current is too swift. All you can do is to keep her nose straight."

The light of the moon was now filling the chasm and the adventurers could see distinctly for a hundred yards or more ahead of them. Each minute seemed to add to the swiftness and size of the stream, and by the use of his paddle Wabi found that it was constantly deepening, until he could no longer touch bottom. Rod's eyes were ceaselessly on the alert for familiar signs along the shore. He was sure that he knew when they passed the spot where he killed the silver fox, and he called Wabi's attention to it. Then the rocks sped past with increasing swiftness, and as the moon rose higher the three could see where the overflowing torrent sent out little streams that twisted and dashed themselves into leaping foam in the wildness of the chasm beyond the main channel. These increased in number and size as the journey continued, until Mukoki began to feel the influence of their currents and called on Wabi and Rod for assistance. Suddenly Rod gave a muffled shout as they shot past a mass of huge boulders on their right.

"That's where I camped the night I dreamed of the skeletons!" he cried. "I don't know what the stream is like from here on. Be careful!"

Wabi gave a terrific lunge with his paddle and the cone of a black rock hissed past half a canoe length away.

"It's as black as a dungeon ahead, and I can hear rocks!" he shouted. "Bring her in if you can, Muky, bring her in!"

There came the sudden sharp crack of snapping wood and a low exclamation of alarm fell from Mukoki. His paddle had broken at the shaft. In a flash Rod realized what had happened and passed back his own, but that moment's loss of time proved almost fatal. Freed of its guiding hand the birch bark swung broadside to the current, and at the same time Wabi's voice rose in a shrill cry of warning.

"It's not rocks, it's a whirlpool!" he yelled. "The other shore, swing her out, swing her out!"

He dug his own paddle deep down into the racing current and from behind Mukoki exerted his most powerful efforts, but it was too late! A hundred feet ahead the stream tore between two huge rocks as big as houses, and just beyond these Rod caught a glimpse of frothing water churning itself milk-white in the moonlight. But it was only a glimpse. With a velocity that was startling the canoe shot between the rocks, and as a choking sea of spray leaped into their faces Wabigoon's voice came back again in a loud command for the others to hang to the gunwales of their frail craft. For an instant, in which his thoughts seemed to have left him, a roaring din filled Rod's ears; a white, churning mist hid everything but his own arms and clutching hands, and then the birch bark darted with the sudden impetus of a freshly-shot arrow around the jagged edge of the boulder—and he could see again.

Here was the whirlpool! More than once Wabi had told him of these treacherous traps, made by the mountain streams, and of the almost certain death that awaited the unlucky canoe man drawn into their smothering embrace. There was no angry raging of the flood here; at first it seemed to Rod that they were floating almost without motion upon a black, lazy sea that made neither sound nor riffle. Scarce half a dozen canoe lengths away he saw the white center of the maelstrom, and there came to his ears above the dash of the stream between the two great rocks a faint hissing sound that curdled the blood in his veins, the hissing of the treacherous undertow that would soon drag them to their death! In the passing of a thought there flashed into the white youth's mind a story that Mukoki had told him of an Indian who had been lost in one of these whirlpools of the spring floods, and whose body had been tossed and pitched about in its center for more than a week. For the first time the power of speech came to him.

"Shall we jump?" he shouted.

"Hang to the canoe."

Wabi fairly shrieked the words, and yet as he spoke he drew himself half erect, as if about to leap into the flood. The momentum gathered in its swift rush between the rocks had carried their frail craft almost to the outer edge of the deadly trap, and as this momentum ceased and the canoe yielded to the sucking forces of the maelstrom the young Indian shrieked out his warning again.

"Hang to the canoe!"

The words were scarcely out of his mouth when he stood erect and launched himself like an animal into the black depths toward shore. With a terrified cry Rod rose to his knees. In another instant he would have plunged recklessly after Wabi, but Mukoki's voice sounding behind him, snarling in its fierceness, stopped him.

"Hang to canoe!"

There came a jerk. The bow of the canoe swung inward and the stern whirled so quickly that Rod, half kneeling, nearly lost his balance. In that instant he turned his face and saw the old warrior standing, as Wabigoon had done before him, and as Mukoki leaped there came for a third time that warning cry:

"Hang to canoe!"

And Rod hung. He knew that for some reason those commands were meant for him, and him alone; he knew that the desperate plunges of his comrades were not inspired by cowardice or fear, but not until the birch bark ground upon the shore and he tumbled out in safety did he fully comprehend what had happened. Holding the rope with which they tied their canoe, Wabigoon had taken a desperate chance. His quick mind had leaped like a flash of powder to their last hope, and at the crucial moment, just as the momentum of the birch bark gave way to the whirling forces of the pool, he had jumped a good seven feet toward shore, and had found bottom! Another twelve inches of water under him and all would have been lost.

Wabigoon stood panting and dripping wet, and in the moonlight his face was as white as the tub-like spot of foam out in the center of the maelstrom.

"That's what you call going to kingdomcome and getting out again!" he gasped. "Muky, that was the closest shave we've ever had! It has your avalanche beaten to a frazzle!"

Mukoki was dragging the canoe upon the pebbly shore, and still overcome by the suddenness of all that had happened Rod went to his assistance.

The adventurers now discovered themselves in a most interesting situation. The night had indeed been one of curious and thrilling happenings for them, and here was a pretty climax to it all! They had escaped the mad hunter by running into the almost fatal grip of the whirlpool, and now they had escaped the perils of that seething death-trap by plunging into a tiny rock-bound prison which seemed destined to hold them for all time, or at least until the floods of spring subsided. Straight above them, and shutting them in entirely, rose precipitous rock walls. On the only open side was the deadly maelstrom.

Even Mukoki as he glanced about him was struck by the humor of their situation, and chuckled softly.

Wabi stood with his hands deep in his soaked pockets, facing the moonlit walls. Then he turned to Rod, and grinned; then he faced the whirlpool, and after that his eyes swept the space of sky above them. The situation was funny, at first; but when he looked at the white youth again the smile had died out of his face.

"Wouldn't that madman have fun if he found us now!" he whispered.

Mukoki was traveling slowly around the rock walls. The space in which they were confined was not more than fifty feet in diameter, and there was not even a crack by means of which a squirrel might have found exit. The prison was perfect. The old pathfinder came back and sat down with a grunt.

"We might as well have supper and a good sleep," suggested Rod, who was hungry. "Surely we need fear no attack from beast or man to-night!"

At least there was this consolation, and the gold hunters ate a hearty meal of cold bear meat and prepared for slumber. The night was unusually warm, and both Mukoki and Wabigoon hung out their wet clothes to dry while they slept in their blankets. Rod did not open his eyes again until Wabi awakened him in the morning. Both Indians were dressed and it was evident that they had been up for some time. When Rod went to the water to wash himself he was surprised to find all of their supplies repacked in the canoe, as though their journey was about to be resumed immediately after breakfast, and when he returned to where Mukoki and Wabigoon had placed their food on a flat stone in the center of what he had regarded as their prison, he observed that both of his companions were in an unusually cheerful frame of mind.

"Looks as though you expected to get out of here pretty soon," he said, nodding toward the canoe.

"So we do!" responded Wabi. "We're going to take a swim through the whirlpool!"

He laughed at the incredulity in Rod's face.

"That is, we're going to navigate along the edge of it," he amended. "Muky and I have tied together every bit of rope and strap in our outfit, even to our gun-slings, and we've got a piece about eighty feet long. We'll show you how to use it after breakfast."

It took but a few minutes to dispose of the rather unappetizing repast of cold bear meat, biscuits and water. Wabi then led the way to the extreme edge of the great rock which formed the eastern wall of their prison, waded in the water to his knees, and directed Rod's gaze to a point of land jutting out into the stream about sixty feet beyond the rock.

"If we can reach that," explained Wabi, "we can portage around the rest of the whirlpool to the main channel. The water is very deep along the edge of this rock, but the undertow doesn't seem to have any great force. I believe that we can make it. The experiment won't be a dangerous one at any rate."

The canoe was now dragged to the edge of the rock and launched, Mukoki taking his place in the stern while Wabigoon placed Rod a little ahead of the midship rib.

"You must paddle on your left side, every minute and as fast as you can," advised the young Indian. "I am to remain behind, holding one end of this rope, so that if you are drawn toward the maelstrom I can pull you back. Understand?"

"Yes—but you. How—"

"Oh, I'll swim!" said Wabi in rank bravado. "I don't mind a little whirlpool like that at all!"

Mukoki chuckled in high humor, and Roderick asked no more questions, but at Wabi's command dug in his paddle and kept at it until the birch bark safely made the point of land beyond the rock. When he looked back Wabi had tied the rope around his body and was already waist deep in the water. At a signal from Mukoki the young Indian plunged fearlessly into the edge of the whirlpool and like a great floundering fish he was quickly pulled across to safety. Most of his clothes had been brought over in the canoe, and after Wabigoon had exchanged his wet garments for these the adventurers were ready to continue their journey down the chasm. A short portage brought them to the main channel of the stream, where they once more launched their birch bark.

"If the whole trip is as exciting as this we'll never reach our gold," said Wabi, as they slipped out into the swift current. "A madman, a whirlpool and a prison, all in one night, is almost more than we can stand."

"There's a good deal of truth in the old saying that it never rains but it pours," replied Rod. "Maybe we'll have smooth sailing from now on."

"Mebby!" grunted the old pathfinder from behind.

Rod's optimism was vindicated for that day, at least. Until noon the canoe sped swiftly down the chasm without mishap. The stream, to which each mile added its contribution of flood water from the mountain tops, increased constantly in width and depth, but only now and then was there a rock to threaten their progress, and no driftwood at all. When the gold seekers landed for dinner they were confident of two things: that they had passed far beyond the mad hunter's reach, and were very near to the first waterfall. Memory of the thrilling experiences through which they had so recently run the gauntlet was replaced by the most exciting anticipation of the sound and sight of that first waterfall, which was so vitally associated with their search for the lost treasure. This time a hearty dinner was cooked, and it took more than an hour to prepare and eat it.

When the journey was resumed Mukoki placed himself in the bow, his sharp eyes scanning the rocks and mountain walls ahead of him. Two hours after the start he gave an exultant exclamation, and raised a warning hand above his head. The three listened. Faintly above the rush of the swift current there came to their ears the distant rumble of falling water!

Forgetful now of the madman back in the chasm, oblivious of everything but the fact that they had at last reached the first of the three falls which were to lead them to the gold, Wabi gave a whoop that echoed and reechoed between the mountain walls, and Rod joined him with all the power of his lungs. Mukoki grinned, chuckled in his curious way, and a few moments later signaled Wabi to guide the canoe ashore.

"We portage here," he explained. "Current swift there—mebby go over fall!"

A short carry of two or three hundred yards brought them to the cataract. It was, as Mukoki had said after his long trip of exploration a few months before, a very small fall, not more than a dozen feet in height. But over it there was now rushing a thundering deluge of water. An easy trail led to the stream below it, and no time was lost in getting under way again.

Although they had traveled fully forty miles since morning, the day had been an easy and most interesting one for the three adventurers. On the swift current of the chasm stream they had worked but little, and the ceaseless change of scenery in this wonderful break between the mountain ridges held an ever-increasing fascination for them. Late in the afternoon, the course changed from its northeasterly direction to due north, and at this point there was an ideal spot for camping. Over an extent of an acre or more there was a sweeping hollow of fine white sand, with great quantities of dry wood cluttering the edge of the depression.

"That's a curious spot!" said Wabi as they drew up their canoe. "Looks like—"

"A lake," grunted Mukoki. "Long time ago—a lake."

"The curve of the stream right here has swept up so much sand that the water can't get into it," added Rod, looking the place over.

Wabi had gone a few paces back. Suddenly he stopped, and with a half shout he gesticulated excitedly to his companions. Something in his manner took Rod and Mukoki to him on the run.

When they came up the Indian youth stood mutely pointing at something in the sand.

Clearly imprinted in that sand was the shape of a human foot, a foot that had worn neither boot nor moccasin when it left its trail in the lake bed, but which was as naked as the quivering hand which Wabigoon now held toward it!

And from that single footprint the eyes of the astonished adventurers traveled quickly to a hundred others, until it seemed to them that a dozen naked savages must have been dancing in these sands only a few hours before.

And Rod, glancing toward the driftwood, saw something else,—something toward which he pointed, speechless, white with that same strange excitement that had taken possession of Wabigoon!



CHAPTER XIII

THE THIRD WATERFALL

The others followed Rod's arm. Behind him he heard the gentle click of Wabigoon's revolver and the sharp, vicious snap of the safety on Mukoki's rifle.

From beyond the driftwood there was rising a thin spiral of smoke!

"Whoever they are, they have certainly seen or heard us!" said Wabi, after they had stood in silence for a full minute.

"Unless they are gone from camp," replied Rod in a whisper.

"Keep eyes open!" warned Mukoki as they advanced cautiously in the direction of the smoke. "No can tell what, I guess so!"

He was first to mount the driftwood, and then he gave vent to a huge grunt. The smoke was rising from beside a charred log which was heaped half-way up its side with ashes and earth. In a flash the meaning of the ash and dirt dawned on Rod and his companions. The fire was banked. Those who had built it were gone, but they expected to return. The naked footprints were thick about the camp-fire, and close to one end of the charred log were scattered a number of bones. One after another Mukoki picked up several of these and closely examined them. While Rod and Wabigoon were still gazing about them in blank astonishment, half expecting attack from a savage horde at any moment, the old warrior had already reached a conclusion, and calling to his companions he brought their attention to the tracks in the sand.

"Same feet!" he exclaimed. "One man mak' all track!"

"Impossible!" cried Wabi. "There are—thousands of them!"

Mukoki grunted and fell upon his knees.

"Heem big toe—right foot—broke sometime. Same in all track. See?"

Disgusted at his own lack of observation, Wabigoon saw at once that the old pathfinder was right. The joint of the big toe on the right foot was twisted fully half an inch outward, a deformity that left a peculiar impression in the sand, and every other track bore this telltale mark. No sooner were the two boys convinced of the correctness of Mukoki's assertion than another and still more startling surprise was sprung on them. Holding out his handful of bones, Mukoki said:

"Meat no cook—eat raw!"

"Great Scott!" gasped Rod.

Wabi's eyes flashed with a new understanding, and as he gazed into Rod's astonished face the latter, too, began to comprehend the significance of it all.

"It must have been the madman!"

"Yes."

"And he was here yesterday!"

"Probably the day before," said Wabi. The young Indian turned suddenly to Mukoki. "What did he want of the fire if he didn't cook meat?" he asked.

Mukoki shrugged his shoulders but did not answer.

"Well, it wasn't cooked, anyway," declared Wabi, again examining the bones. "Here are chunks of raw flesh clinging to the bones. Perhaps he just singed the outside of his meat."

The old Indian nodded at this suggestion and turned to investigate the fire. On the end of the log were two stones, one flat and the other round and smooth, and after a moment's inspection of these he dropped an exclamation which was unusual for him, and which he used only in those rare intervals when all other language seemed to fail him.

"Bad dog man—mak' bullet—here!" he called, holding out the stones. "See—gold—gold!"

The boys hurried to his side.

"See—gold!" he repeated excitedly.

In the center of the flat stone there was a gleaming yellow film. A single glance told the story. With the round stone for a hammer the mad hunter had pounded his golden bullets into shape upon the flat stone! There was no longer a doubt in their minds; they were in the madman's camp. That morning they had left this strange creature of the wilderness fifty miles away. But how far away was he now? The fire slumbering under its covering of ash and earth proved that he meant to return—and soon. Would he travel by night as well as by day? Was it possible that he was already close behind them?

"He travels with the swiftness of an animal," said Wabi, speaking in a low voice to Rod. "Perhaps he will return to-night!"

Mukoki overheard him and shook his head.

"Mak' heem through chasm in two day on snow-shoe," he declared, referring to his trip of exploration to the first waterfall over the snows of the previous winter. "No mak' in t'ree day over rock!"

"If Mukoki is satisfied, I am," said Rod. "We can pull up behind the driftwood on the farther edge of the lake bed."

Wabi made no objection, and the camp site was chosen. Strangely enough, with the discovery of the footprints, the fire, the picked bones and the stones with which the mad hunter had manufactured his golden bullets, Mukoki seemed to have lost all fear of the wild creature of the chasm. He was confident now that he had only a man to deal with, a man who had gone "bad dog," and his curiosity overcame his alarm. His assurance served to dispel the apprehension of his companions, and sleep came early to the tired adventurers. Nor did anything occur during the night to awaken them.

Soon after dawn the trip down the chasm stream was resumed. With the abrupt turning of the channel to the north, however, there was an almost immediate change in the topography of the country. Within an hour the precipitous walls of the mountains gave place to verdure-covered slopes, and now and then the gold seekers found themselves between plains that swept back for a mile or more on either side. Frequent signs of game were observed along the shores of the river and several times during the morning moose and caribou were seen in the distance. A few months before, when they had invaded the wilderness to hunt and trap, this country would have aroused the wildest enthusiasm among Rod and his friends, but now they gave but little thought to their rifles. That morning they had set out with the intention of reaching the second waterfall before dusk, and it was with disappointment rather than gladness that they saw the swift current of the chasm torrent change into the slower, steadier sweep of a stream that had now widened into a fair-sized river. According to the map the second fall was about fifty-five miles from the mad hunter's camp. Darkness found them still fifteen miles from where it should be.

Excitement kept Rod awake most of that night. Try as he would, he could not keep visions of the lost treasure out of his mind. The next day they would be far on their way to the third and last waterfall. And then—the gold! That they might not find it, that the passing of half a century or more might have obliterated all traces left by its ancient discoverers, never for a moment disturbed his belief.

He was the first awake the following morning, the first to take his place in the canoe. Every minute now his ears were keenly attuned for that distant sound of falling water. But hours passed without a sign of it. Noon came. They had traveled six hours and had covered twenty-five miles instead of fifteen! Where was the waterfall?

There was a little more of anxiety in Wabigoon's eyes when they resumed their journey after dinner. Again and again Rod looked at his map, figuring out the distances as drawn by John Ball, the murdered Englishman. Surely the second waterfall could not be far away now! And still hour after hour passed, and mile after mile slipped behind them, until the three knew that they had gone fully thirty miles beyond where the cataract should have been, if the map was right. Twilight was falling when they stopped for supper. For the last hour Mukoki had spoken no word. A feeling of gloom was on them all; without questioning, each knew what the fears of the others were.

Was it possible that, after all, they had not solved the secret of the mysterious map?

The more Rod thought of it the more his fears possessed him. The two men who fought and died in the old cabin were on their way to civilization. They were taking gold with them, gold which they meant to exchange for supplies. Would they, at the same time, dare to have in their possession a map so closely defining their trail as the rude sketch on the bit of birch bark? Was there not some strange key, known only to themselves, necessary to the understanding of that sketch?

Mukoki had taken his rifle and disappeared in the plain along the river, and for a long time after they had eaten their bear steak and drank their hot coffee Rod and Wabigoon sat talking in the glow of the camp-fire. The old warrior had been gone for about an hour when suddenly there came the report of a gun from far down the stream, which was quickly followed by two others—three in rapid succession. After an interval of a few seconds there sounded two other shots.

"The signal!" cried Rod. "Mukoki wants us!"

Wabigoon sprang to his feet and emptied the five shots of his magazine into the air.

"Listen!"

Hardly had the echoes died away when there came again the reports of Mukoki's rifle.

Without another word the two boys hurried to the canoe, which had not been unloaded.

"He's a couple of miles down-stream," said Wabi, as they shoved off. "I wonder what's the matter?"

"I can make a pretty good guess," replied Rod, his voice trembling with a new excitement. "He has found the second waterfall!"

The thought gave fresh strength to their aching arms and the canoe sped swiftly down the stream. Fifteen minutes later another shot signaled to them, this time not more than a quarter of a mile away, and Wabi responded to it with a loud shout. Mukoki's voice floated back in an answering halloo, but before the young hunters came within sight of their comrade another sound reached their ears,—the muffled roar of a cataract! Again and again the boys sent their shouts of joy echoing through the night, and above the tumult of their own voices they heard the old warrior calling on them to put into shore. Mukoki was waiting for them when they landed.

"This is big un!" he greeted. "Mak' much noise, much swift water!"

"Hurrah!" yelled Rod for the twentieth time, jumping up and down in his excitement.

"Hurrah!" cried Wabi.

And Mukoki chuckled, and grinned, and rubbed his leathery hands together in high glee.

At last, when they had somewhat cooled down, Wabi said:

"That John Ball was a pretty poor fellow at a guess, eh? What do you say, Rod?"

"Or else pretty clever," added Rod. "By George, I wonder if he had a reason for making his scale fifty miles or so out of the way?"

Wabi looked at him, only partly understanding.

"What do you mean?"

"I mean that our third waterfall is more than likely to be mighty close to this one! And if it is—well, John Ball had a reason, and a good one! If we strike the last fall to-morrow it will be pretty good proof that he drew the map in a way intended to puzzle somebody,—perhaps his two partners, who were just about to start for civilization."

"Muky, how far have we come?" asked Wabigoon.

"T'ree time first fall," replied the old Indian quickly.

"A hundred and fifty miles—in three days and one night. I don't believe that is far out of the way. Then, according to the map, we should still be a hundred miles from the third fall."

"And we're not more than twenty-five!" declared Rod confidently. "Let's build a fire and go to bed. We'll have enough to do to-morrow—hunting gold!" The fourth day's journey was begun before it was yet light. Breakfast was eaten in the glow of the camp-fire, and by the time dawn broke the adventurers were already an hour upon their way. Nothing but confidence now, animated them. The mad hunter and his golden bullets were entirely forgotten in these last hours of their exciting quest. Once, far back, Rod had thought with chilling dread that this might be the madman's trail, that his golden bullets might come from the treasure they were seeking. But he gave no thought to this possibility now. His own belief that the third and last fall was not far distant, in spite of the evidence of the map, gradually gained possession of his companions, and the nerves of all three were keyed to the highest tension of expectancy. The preceding night Mukoki had made himself a paddle to replace the one he had broken, and not a stroke of the three pairs of arms was lost. Early in the morning a young moose allowed them to pass within a hundred yards of him. But no shot was fired, for to obtain the meat would have meant an hour's loss of time.

Two hours after the start the country again began taking on a sudden change. From east and west the wild mountain ridges closed in, and with each mile's progress the stream narrowed and grew swifter, until again it was running between chasm walls that rose black and silent over the adventurers' heads. Darker and gloomier became the break between the mountains. Far above, a thousand feet or more, dense forests of red pine flung their thick shadows over the edge of the chasm, in places almost completely shutting out the light of day. This was not like the other chasm. It was deeper and darker and more sullen. Under its walls the gloom was almost that of night. Its solitude was voiceless; not a bird fluttered or chirped among its rocks; the lowest of whispered words sounded with startling distinctness. Once Rod spoke aloud, and his voice rose and beat itself in the cavernous depths of the walls until it seemed as though he had shouted. Now they ceased paddling, and Mukoki steered. Noiselessly the current swept them on. In the twilight gloom Rod's face shone with singular whiteness. Mukoki and Wabigoon crouched like bronze silhouettes. It was as if some mysterious influence held them in its power, forbidding speech, holding their eyes in staring expectancy straight ahead, filling them with indefinable sensations that made their hearts beat faster and their blood tingle.

Softly, from far ahead, at last there came a murmur. It was like the first gentle whispering of an approaching wind, the soughing of a breath among the pines at the top of the chasm. But a wind among the trees rises, and then dies away, like a chord struck low and gently upon some soft-toned instrument. This whisper that came up the chasm remained. It grew no louder, and sometimes it almost faded away, until the straining ears of those who listened could barely detect it; but after a moment it was there again, as plainly as before. Little by little it became more distinct, until there were no longer intervals when it died away, and at last Wabigoon turned in the bow and faced his companions, and though he spoke no word there was the gleam of a great excitement in his eyes. Rod's heart beat like a drum. He, too, began to understand. That moaning, whispering sound floating up the chasm was not the wind, but the far-away rumble of the third waterfall!

Mukoki's voice broke the tense silence from behind.

"That the fall!"

Wabigoon replied in words scarcely louder than a whisper. There was no joyful shouting now, as there had been at the discovery of the second fall. Even Mukoki's voice was so low that the others could barely hear. Something between these chasm walls seemed to demand silence from them, and as the rumble of the cataract came more and more clearly to their ears they held their breath in voiceless anticipation. A few hundred yards ahead of them was the treasure which men long since dead had discovered more than half a century before; between the black mountain walls that so silently guarded that treasure there seemed to lurk the spirit presence of the three men who had died because of it. Here, somewhere very near, John Ball had been murdered, and Rod almost fancied that along the sandy edge of the chasm stream they might stumble on the footprints of the men whose skeletons they had discovered in the ancient cabin.

Mukoki uttered no sound as he guided the canoe ashore. Still without word, the three picked up their rifles and Wabigoon led the way along the edge of the stream. Soon it dashed a swift racing torrent between the rocks, and Rod and his companions knew that they were close upon the fall. A hundred yards or more and they saw the white mist of it leaping up before their eyes. Wabi began to run, his moccasined feet springing from stone to stone with the caution of a hunter approaching game, and Mukoki and Rod came close behind him.

They paused upon the edge of a great mass of rock with the spray of the plunging cataract rising in their faces. Breathless they gazed down. It was not a large fall. Wabi silently measured it at forty feet. But it added just that much more to the depth and the gloom of the chasm beyond, into which there seemed no way of descent. The rock walls rose sheer and black, with clumps of cedar and stunted pine growing at their feet. Farther on the space between the mountains became wider, and the river reached out on either side, frothing and beating itself into white fury in a chaos of slippery water-worn rocks.

Down there—somewhere—was the golden treasure they had come to seek, unless the map lied! Was it among those rocks, where the water dashed and fumed? Was it hidden in some gloomy cavern of the mountain sides, its trail concealed by the men who discovered it half an age ago? Would they find it, after all—would they find it?

A great gulp of excitement rose in Rod's throat, and he looked at Wabigoon.

The Indian youth had stretched out an arm. His eyes were blazing, his whole attitude was one of tense emotion.

"There's the cabin," he cried, "the cabin built by John Ball and the two Frenchmen! See, over there among those cedars, almost hidden in that black shadow of the mountain! Great Scott, Muky—Rod—can't you see? Can't you see?"



CHAPTER XIV

THE PAPER IN THE OLD TIN BOX

Slowly out of that mysterious gloom there grew a shape before Rod's eyes. At first it was only a shadow, then it might have been a rock, and then the gulp in his throat leaped out in a shout when he saw that Wabigoon's sharp eyes had in truth discovered the old cabin of the map. For what else could it be? What else but the wilderness home of the adventurers whose skeletons they had found, Peter Plante and Henri Langlois, and John Ball, the man whom these two had murdered?

Rod's joyous voice was like the touch of fire to Wabi's enthusiasm and in a moment the oppressive silence of their journey down the chasm was broken by the wild cheers which the young gold seekers sent echoing between the mountains. Grimacing and chuckling in his own curious way, Mukoki was already slipping along the edge of the rock, seeking some break by which he might reach the lower chasm. They were on the point of turning to the ascent of the mountain, along which they would have to go until they found such a break, when the old pathfinder directed the attention of his companions to the white top of a dead cedar stub projecting over the edge of the precipice.

"Go down that, mebby," he suggested, shrugging his shoulders to suggest that the experiment might be a dangerous one.

Rod looked over. The top of the stub was within easy reach, and the whole tree was entirely free of bark or limbs, a fact which in his present excitement did not strike him as especially unusual. Swinging his rifle strap over his shoulders he reached out, caught the slender apex of the stub, and before the others could offer a word of encouragement or warning was sliding down the wall of the rock into the chasm. Wabi was close behind him, and not waiting for Mukoki's descent the two boys hurried toward the cabin. Half-way to it Wabi stopped.

"This isn't fair. We've got to wait for Muky."

They looked back. Mukoki was not following. The old warrior was upon his knees at the base of the dead tree, as though he was searching for something among the rocks at its foot. Then he rose slowly, and rubbed his hands along the stub as high as he could reach. When he saw that Rod and Wabi were observing him he quickly came toward them, and Wabigoon, who was quick to notice any change in him, was confident that he had made a discovery of some kind.

"What have you found, Muky?"

"No so ver' much. Funny tree," grunted the Indian.

"Smooth as a fireman's brass pole," added Rod, seeing no significance in Mukoki's words. "Listen!"

He stopped so suddenly that Wabigoon bumped into him from behind.

"Did you hear that?"

"No."

For a few moments the three huddled close together in watchful silence. Mukoki was behind the boys or they would have seen that his rifle was ready to spring to his shoulder and that his black eyes were snapping with something not aroused by curiosity alone. The cabin was not more than twenty paces away. It was old, so old that Rod wondered how it had withstood the heavy storms of the last winter. A growth of saplings had found root in its rotting roof and the logs of which it was built were in the last stage of decay. There was no window, and where the door had once been there had grown a tree a foot in diameter, almost closing the narrow aperture through which the mysterious inhabitants had passed years before. A dozen paces, five paces from this door, and Mukoki's hand reached out and laid itself gently upon Wabi's shoulder. Rod saw the movement and stopped. A strange look had come into the old Indian's face, an expression in which there was incredulity and astonishment, as if he believed and yet doubted what his eyes beheld. Mutely he pointed to the tree growing before the door, and to the reddish, crumbling rot into which the logs had been turned by the passing of generations.

"Red pine," he said at last. "That cabin more'n' twent' t'ous'nd year old!"

There was an awesome ring in his voice. Rod understood, and clutched Wabi's arm. In an instant he thought of the other old cabin, in which they had found the skeletons. They had repaired that cabin and had passed the winter in it, and they knew that it had been built half a century or more before. But this cabin was beyond repair. To Rod it seemed as though centuries of time instead of decades had been at work on its timbers. Following close after Wabi he thrust his head through the door. Deep gloom shut out their vision. But as they looked, steadily inuring their eyes to the darkness within, the walls of the old cabin took form, and they saw that everywhere was vacancy. There was no ancient table, as in the other cabin they had discovered at the head of the first chasm, there were no signs of the life that had once existed, not even the remnants of a chair or a stool. The cabin was bare.

Foot by foot the two boys went around its walls. Mukoki took but a single glance inside and disappeared. Once alone he snapped down the safety of his rifle. Quickly, as if he feared interruption, he hurried around the old cabin, his eyes close to the earth. When Rod and Wabi returned to the door he was at the edge of the fall, crouching low among the rocks like an animal seeking a trail. Wabi pulled his companion back.

"Look!"

The old warrior rose, suddenly erect, and turned toward them, but the boys were hidden in the gloom. Then he hurried to the dead stub beside the chasm wall. Again he reached far up, rubbing his hand along its surface.

"I'm going to have a look at that tree!" whispered Wabi. "Something is puzzling Are you coming?"

He hurried across the rock-strewn opening, but Rod hung back. He could not understand his companions. For weeks and months they had planned to find this third waterfall. Visions of a great treasure had been constantly before their eyes, and now that they were here, with the gold perhaps under their very feet, both Mukoki and Wabigoon were more interested in a dead stub than in their search for it! His own heart was almost bursting with excitement. The very air which he breathed in the old cabin set his blood leaping with anticipation. Here those earlier adventurers had lived half a century or more ago. In it the life-blood of the murdered John Ball might have ebbed away. In this cabin the men whose skeletons he had found had slept, and planned, and measured their gold. And the gold! It was that and not the stub that interested Roderick Drew! Where was the lost treasure? Surely the old cabin must hold some clue for them, it would at least tell them more than the limbless white corpse of a tree!

From the door he looked back into the dank gloom, straining his eyes to see, and then glanced across the opening. Wabi had reached the stub, and both he and Mukoki were on their knees beside it. Probably they have found the marks of a lynx or a bear, thought Rod. A dozen paces away something else caught his eyes, a fallen red pine, dry and heavy with pitch, and in less than a minute he had gone to it and was back with a torch. Breathlessly he touched the tiny flame of a match to the stick. For a moment the pitch sputtered and hissed, then flared into light, and Rod held the burning wood above his head.

The young gold seeker's first look about him was disappointing. Nothing but the bare walls met his eyes. Then, in the farthest corner, he observed something that in the dancing torch-light was darker than the logs themselves, and he moved toward it. It was a tiny shelf, not more than a foot long, and upon it was a small tin box, black and rust-eaten by the passing of ages. With trembling fingers Rod took it in his hand. It was very light, probably empty. In it he might find the dust of John Ball's last tobacco. Then, suddenly, as he thought of this, he stopped in his search and a muffled exclamation of surprise fell from him. In the glow of the torch he looked at the tin box. It was crumbling with age and he might easily have crushed it in his hand—and yet it was still a tin box! If this box had remained why had not other things? Where were the pans and kettles, the pail and frying-pan, knives, cups and other articles which John Ball and the two Frenchmen must at one time have possessed in this cabin?

He returned to the door. Mukoki and Wabigoon were still at the dead stub. Even the flare of light in the old cabin had not attracted them. Tossing his torch away Rod tore off the top of the tin box. Something fell at his feet, and as he reached for it he saw that it was a little roll of paper, almost as discolored as the rust-eaten box itself. As gently as Mukoki had unrolled the precious birchbark map a few months before he smoothed out the paper. The edges of it broke and crumbled under his fingers, but the inner side of the roll was still quite white. Mukoki and Wabigoon, looking back, saw him suddenly turn toward them with a shrill cry on his lips, and the next instant he was racing in their direction, shouting wildly at every step.

"The gold!" he shrieked. "The gold! Hurrah!"

He was almost sobbing in his excitement when he stopped between them, holding out the bit of paper.

"I found it in the cabin—in a tin box! See, it's John Ball's writing—the writing that was on the old map! I found it—in a tin box—"

Wabi seized the paper. His own breath came more quickly when he saw what was upon it. There were a few lines of writing, dim but still legible, and a number of figures. Across the top of the paper was written,

"Account of John Ball, Henri Langlois, and Peter Plante for month ending June thirtieth, 1859."

Below these lines was the following:

"Plante's work: nuggets, 7 pounds, nine ounces; dust, 1 pound, 3 ounces. Langlois' work: nuggets, 9 pounds, 13 ounces; dust, none. Ball's work: nuggets, 6 pounds, 4 ounces; dust, 2 pounds, 3 ounces. Total, 27 pounds. Plante's share, 6 pounds, 12 ounces. Langlois' share, 6 pounds, 12 ounces. Ball's share, 13 pounds, 8 ounces. Division made."

Softly Wabigoon read the words aloud. When he finished his eyes met Rod's, Mukoki was still crouching at the foot of the stub, staring at the two boys in silence, as if stupefied by what he had just heard.

"This doesn't leave a doubt," said Wabi at last. "We've struck the right place!"

"The gold is somewhere—very near—"

Rod could not master the tremble in his voice. As though hoping to see the yellow treasure heaped in a pile before his eyes he turned to the waterfall, to the gloomy walls of the chasm, and finally extended an arm to where the spring torrent, leaping over the edge of the chasm above, beat itself into frothing rage among the rocks between the two mountains.

"It's there!"

"In the stream?"

"Yes. Where else near this cabin would they have found pure nuggets of gold? Surely not in rock! And gold-dust is always in the sands of streams. It's there—without a doubt!"

Both Indians went with him to the edge of the water.

"The creek widens here until it is very shallow," said Wabi. "I don't believe that it is more than four feet deep out there in the middle. What do you say—" He paused as he saw Mukoki slip back to the dead stub again, then went on, "What do you say to making a trip to the canoe after grub for our dinner, and the pans?"

The first flash of enthusiasm that had filled Wabigoon on reading the paper discovered by Rod was quickly passing away, and the white youth could not but notice the change which came over both Mukoki and his young friend when they stood once more beside the smooth white stub that reached up to the floor of the chasm above. He controlled his own enthusiasm enough to inspect more closely the dead tree which had affected them so strangely. The discovery he made fairly startled him. The surface of the stub was not only smooth and free of limbs, but was polished until it shone with the reflecting luster of a waxed pillar! For a moment he forgot the paper which he held in his hand, forgot the old cabin, and the nearness of gold. In blank wonder he stared at Mukoki, and the old Indian shrugged his shoulders.

"Ver' nice an' smooth!"

"Ver' dam' smooth!" emphasized Wabi, without a suggestion of humor in his voice.

"What does it mean?" asked Rod.

"It means," continued Wabigoon, "that this old stub has for a good many years been used! by something as a sort of stairway in and out of this chasm! Now if it were a bear, there would be claw marks. If it were a lynx, the surface of the stub would be cut into shreds. Any kind of animal would have left his mark behind, and no animal would have put this polish on it!"

"Then what in the world—"

Rod did not finish. Mukoki lifted his shoulders to a level with his chin, and Wabi whistled as he looked straight at him.

"Not a hard guess, eh?"

"You mean—"

"That it's a man! Only the arms and legs of a man going up and down that stub hundreds and thousands of times could have worn it so smooth! Now, can you guess who that man is?"

In a flash the answer shot into Rod's brain. He understood now why this old stub had drawn his companions away from their search for gold, and he felt the flush of excitement go out of his own cheeks, and an involuntary thrill pass up his back.

"The mad hunter!"

Wabi nodded. Mukoki grunted and rubbed his hands.

"Gold in bullet come from here!" said the old pathfinder. "Bad dog man ver' swift on trail. We hurry get canoe—cut down tree!"

"That's more than you've said in the last half-hour, and it's a good idea!" exclaimed Wabi. "Let's get our stuff down here and chop this stub into firewood! When he comes back and finds his ladder gone he'll give a screech or two, I'll wager, and then it will be our chance to do something with him. Here goes!"

He started to climb the stub, and a minute or two later stood safely on the rock above.

"Slippery as a greased pole!" he called down. "Bet you can't make it, Rod!"

But Rod did, after a tremendous effort that left him breathless and gasping by the time Wabi stretched out a helping hand to him. Mukoki came up more easily. Taking only their revolvers with them the three hurried to the birch bark, and in a single load brought their possessions to the rock. By means of ropes the packs and other contents of the canoe, and finally the canoe itself, were lowered into the chasm, and while the others looked on Mukoki seized the ax and chopped down the stub.

"There!" he grunted, as a last blow sent the tree crashing among the rocks. "Too high for heem jump!"

"But a mighty good place for him to shoot from," said Wabi, looking up. "We'd better camp out of range."

"Not until we know what we've struck," cried Rod, unstrapping a pan from one of the packs. "Boys, the first thing to do is to wash out a little of that river-bed!"

He started for the creek, with Wabi close behind him bearing a second pan. Mukoki looked after them and chuckled softly to himself as he began making preparations for dinner. Choosing a point where the current had swept up a small bar of pebbles and sand Wabi and Rod both set to work. The white youth had never before panned gold, but he had been told how it was done, and there now shot through him that strange, thrilling excitement which enthralls the treasure hunter when he believes that at last he has struck pay dirt. Scooping up a quantity of the gravel and sand he filled his pan with water, then moved it, quickly back and forth, every few moments splashing some of the "wash" or muddy water, over the side. Thus, filling and refilling his pan with fresh water, he excitedly went through the process of "washing" everything but solid substance out of it.

With each fresh dip into the stream the water in the pan became clearer, and within fifteen minutes the three or four double handfuls of sand and gravel with which he began work dwindled down to one. Scarcely breathing in his eagerness he watched for the yellow gleam of gold. Once a glitter among the pebbles drew a low cry from him, but when with the point of his knife he found it to be only mica he was glad that Wabi had not heard him. The young Indian was squatting upon the sand, with his pan turned toward a gleam of the sun that shot faintly down into the chasm. Without raising his head he called to Rod.

"Found anything?"

"No. Have you?"

"No—yes—but I don't think it's gold"

"What does it look like?"

"It gleams yellow but is as hard as steel."

"Mica!" said Rod.

Neither of the boys looked up during the conversation. With the point of his hunting-knife Rod still searched in the bottom of his pan, turning over the pebbles and raking the gravelly sand with a painstaking care that would have made a veteran gold seeker laugh. Some minutes had passed when Wabi spoke again.

"I say, Rod, that's a funny-looking thing I found! If it wasn't so hard I'd swear it was gold? Want to see it?"

"It's mica," repeated Rod, as another gleam, of "fool's gold" in his own pan caught his eyes. "The stream is full of it!"

"Never saw mica in chunks before," mumbled Wabi, bending low over his pan.

"Chunks!" cried Rod, straightening as if some one had run a pin into his back. "How big is it?"

"Big as a pea—a big pea!"

The words were no sooner out of the young Indian's mouth than Roderick was upon his feet and running to his companion.

"Mica doesn't come in chunks! Where—"

He bent over Wabi's pan. In the very middle of it lay a suspiciously yellow pebble, worn round and smooth by the water, and when Rod took it in his fingers he gave a low whistle of mock astonishment as he gazed down into Wabigoon's face.

"Wabi, I'm ashamed of you!" he said, trying hard to choke back the quiver in his voice. "Mica doesn't come in round chunks like this. Mica isn't heavy. And this is both!"

From the cedars beyond the old cabin came Mukoki's whooping signal that dinner was ready.



CHAPTER XV

THE TREASURE IN THE POOL

For a few moments after Rod's words and Mukoki's signal from the cedars Wabigoon sat as if stunned.

"It isn't—gold," he said, his voice filled with questioning doubt.

"That's just what it is!" declared Rod, his words now rising in the excitement which he was vainly striving to suppress. "It's hard, but see how your knife point has scratched it! It weighs a quarter of an ounce! Are there any more nuggets in there?"

He fell upon his knees beside Wabi, and their two heads were close together, their four eyes eagerly searching the contents of the pan, when Mukoki came up behind them. Rod passed the golden nugget to the old Indian, and rose to his feet.

"That settles it, boys. We've hit the right spot. Let's give three cheers for John Ball and the old map, and go to dinner!"

"I agree to dinner, but cut out the cheers." said Wabi, "or else let's give them under our breath. Notice how hollow our voices sound in this chasm! I believe we could hear a shout half a dozen miles away!"

For their camp Mukoki had chosen a site in the edge of the cedars, and had spread dinner on a big flat rock about which the three now gathered. For inspiration, as Wabi said, the young Indian placed the yellow nugget in the center of the improvised table, and if the enthusiasm with which they hurried through their meal counted for anything there was great merit in the golden centerpiece. Mukoki joined the young gold seekers when they again returned to the chasm stream, and the quest of the yellow treasure was vigorously renewed in trembling and feverish expectancy.

Only those who have lived in this quest and who have pursued that elusive ignis fatuus of all nations—the lure of gold—can realize the sensations which stir the blood and heat the brain of the treasure seeker as he dips his pan into the sands of the stream where he believes nature has hidden her wealth. As Roderick Drew, a child of that civilization where the dollar is law as well as might, returned to the exciting work which promised him a fortune he seemed to be in a half dream. About him, everywhere, was gold! For no moment did he doubt it; not for an instant did he fear that there might be no more gold in the sand and gravel from which Wabigoon's nugget had come. Treasure was in the very sandbar under his feet! It was out there among the rocks, where the water beat itself angrily into sputtering froth; it was under the fall, and down in the chasm, everywhere, everywhere about him. In one month John Ball and his companions had gathered twenty-seven pounds of it, a fortune of nearly seven thousand dollars! And they had gathered it here! Eagerly he scooped up a fresh pan of the precious earth. He heard the swish-swish of the water in Wabigoon's and Mukoki's pans. But beyond this there were no sounds made by them.

In these first minutes of treasure seeking no words were spoken. Who would give the first shout of discovery? Five minutes, ten, fifteen of them passed, and Rod found no gold. As he emptied his pan he saw Wabi scooping up fresh dirt. He, too, had failed. Mukoki had waded out waist deep among the rocks. A second and a third pan, and a little chill of disappointment cooled Rod's blood. Perhaps he had chosen an unlucky spot, where the gold had not settled! He moved his position, and noticed that Wabigoon had done the same. A fourth and a fifth pan and the result was the same. Mukoki had waded across the stream, which was shallow below the fall, and was working on the opposite side. A sixth pan, and Rod approached the young Indian. The excitement was gone out of their faces. An hour and a half—and no more gold!

"Guess we haven't hit the right place, after all," said Wabi.

"It must be here," replied Rod. "Where there is one nugget there must be more. Gold is heavy, and settles. Perhaps it's deeper down in the river bed."

Mukoki came across to join them. Out among the rocks he had found a fleck of gold no larger than the head of a pin, and this new sign gave them all fresh enthusiasm. Taking off their boots both Rod and Wabi joined the old pathfinder in midstream. But each succeeding pan added to the depressing conviction that was slowly replacing their hopes. The shadows in the chasm began growing longer and deeper. Far overhead the dense canopies of red pine shut out the last sun-glow of day, and the gathering gloom between the mountains gave warning that in this mysterious world of the ancient cabin the dusk of night was not far away. But not until they could no longer see the gleaming mica in their pans did the three cease work. Wet to the waist, tired, and with sadly-shattered dreams they returned to their camp. For a short time Rod's hopes were at their lowest ebb. Was it possible that there was no more gold, that the three adventurers of long ago had discovered a "pocket" here, and worked it out? The thought had been growing in his head. Now it worried him.

But his depression did not last long. The big fire which Mukoki built and the stimulating aroma of strong coffee revived his natural spirits, and both Wabi and he were soon laughing and planning again as they made their cedar-bough shelter. Supper on the big flat stone—a feast of bear steak, hot-stone biscuits, coffee, and that most delectable of all wilderness luxuries, a potato apiece,—and the two irrepressible young gold hunters were once more scheming and building their air-castles for the following day. Mukoki listened, and attended to the clothes drying before the fire, now and then walking out into the gloom of the chasm to look up to where the white rim of the fall burst over the edge of the great rock above them. All that afternoon Wabi and Rod had forgotten the mad hunter and the strange, smoothly worn tree. Mukoki had not.

In the glow of the camp-fire the two boys read over again the old account of John Ball and the two Frenchmen. The tiny slip of paper, yellow with age, was the connecting link between them and the dim and romantic past, a relic of the grim tragedy which these black and gloomy chasm walls would probably keep for ever a secret.

"Twenty-seven pounds," repeated Rod, as if half to himself. "That was one month's work!"

"Pretty nearly a pound a day!" gasped Wabi. "I tell you, Rod, we haven't hit the right spot—yet!"

"I wonder why John Ball's share was twice that of his companions'? Do you suppose it was because he discovered the gold in the first place?" speculated Rod.

"In all probability it was. That accounts for his murder. The Frenchmen were getting the small end of the deal."

"Eighteen hundred fifty-nine," mused Rod. "That was forty-nine years ago, before the great Civil War. Say—"

He stopped and looked hard at Wabigoon.

"Did it ever strike you that John Ball might not have been murdered?"

Wabi leaned forward with more than usual eagerness.

"I have had a thought—" he began.

"What?"

"That perhaps he was not killed."

"And that after the two Frenchmen died in the knife duel he returned and got the gold," continued Rod.

"No, I had not thought of that," said Wabi. Suddenly he rose to his feet and joined Mukoki out in the gloom of the chasm.

Rod was puzzled. Something in his companion's voice, in his face and words, disturbed him. What had Wabigoon meant?

The young Indian soon rejoined him, but he spoke no more of John Ball.

When the two boys went to their blankets Mukoki still remained awake. For a long time he sat beside the fire, his hands gripping the rifle across his knees, his head slightly bowed in that statue-like posture so characteristic of the Indian. For fully an hour he sat motionless, and in his own way he was deeply absorbed in thought. Soon after their discovery of the first golden bullet Wabigoon had whispered a few words into his ear, unknown to Rod; and to-night out in the gloom of the chasm, he had repeated those same words. They had set Mukoki's mind working. He was thinking now of something that happened long ago, when, in his reasoning, the wilderness was young and he was a youth. In those days his one great treasure was a dog, and one winter he went with this faithful companion far into the hunting regions of the North, a long moon's travel from his village. When he returned, months later, he was alone. From his lonely hunting shack deep in the solitudes his comrade had disappeared, and had never returned. This all happened before Mukoki met the pretty Indian girl who became his wife, and was afterward killed by the wolves, and he missed the dog as he would have missed a human brother. The Indian's love, even for brutes, is some thing that lives, and more than twenty moons later—two years in the life of a man—he returned once again to the old shack, and there he found Wholdaia, the dog! The animal knew him, and bounded about on three legs for joy, and because of the missing leg Mukoki understood why he had not returned to him two years before. Two years is a long time in the life of a dog, and the gray hairs of suffering and age were freely sprinkled in Wholdaia's muzzle and along his spine.

Mukoki was not thinking of Wholdaia without a reason. He was thinking of Wabigoon's words—and the mad hunter. Could not the mad hunter do as Wholdaia had done? Was it possible that the bad-dog man who shot golden bullets and who screamed like a lynx was the man who had lived there many, many years ago, and whom the boys called John Ball? Those were the thoughts that Wabi had set working in his brain. The young Indian had not suggested this to Rod. He had spoken of it to Mukoki only because he knew the old pathfinder might help him to solve the riddle, and so he had started Mukoki upon the trail.

The next morning, while the others were finishing their breakfast, Mukoki equipped himself for a journey.

"Go down chasm," he explained to Rod "Fin' where get out to plain. Shoot meat."

That day the gold hunters were more systematic in their work, beginning close to the fall, one on each side of the stream, and panning their way slowly down the chasm. By noon they had covered two hundred yards, and their only reward was a tiny bit of gold, worth no more than a dollar, which Rod had found in his pan. By the time darkness again compelled them to stop they had prospected a quarter of a mile down stream without discovering other signs of John Ball's treasure. In spite of their failure they were less discouraged than the previous evening, for this failure, in a way, was having a sedative and healthful effect. It convinced them that there was a hard and perhaps long task ahead of them, and that they could not expect to find their treasure winnowed in yellow piles for them.

Early in the evening Mukoki returned laden with caribou meat, and with the news that the first break in the chasm walls was fully five miles below. The adventurers now regretted that they had chopped down the stub, for it was decided that the next work should be in the stream above the fall, which would necessitate a ten-mile tramp, five miles to the break and five miles back. When the journey was begun at dawn the following morning several days' supplies were taken along, and also a stout rope by means of which the gold hunters could lower themselves back into their old camp when their work above was completed. Rod noticed that the rocks in the stream seemed much larger than when he had first seen them, and he mentioned the fact to Wabigoon.

"The floods are going down rapidly," explained the young Indian. "All of the snow is melted from the sides of the mountains, and there are no lakes to feed this chasm stream. Within a week there won't be more than a few inches of water below the fall."

"And that is when we shall find the gold!" declared Rod with his old enthusiasm. "I tell you, we haven't gone deep enough! This gold has been here for centuries and centuries, and it has probably settled several feet below the surface of the river-bed. Ball and the Frenchmen found twenty-seven pounds in June, when the creek was practically dry. Did you ever read about the discoveries of gold in Alaska and the Yukon?"

"A little, when I was going to school with you."

"Well, the richest finds were nearly always from three to a dozen feet under the surface, and when a prospector found signs in surface panning he knew there was rich dirt below. Well find our gold in this chasm, and near the fall!"

Rod's confidence was the chief thing that kept up the spirits of the treasure seekers during the next few days, for not the first sign of gold was discovered above the fall. Yard by yard the prospectors worked up the chasm until they had washed its sands for more than a mile. And with the passing of each day, as Wabigoon had predicted, the stream became more and more shallow, until they could wade across it without wetting themselves above their knees. At the close of the fourth day the three lowered themselves over the face of the rock into the second chasm. So convinced was Rod in his belief that the gold was hidden deep down under the creek bed that he dug a four-foot hole by torch-light and that night after supper washed out several pans of dirt in the glow of the camp-fire. He still found no signs of gold.

The next day's exertions left no room for doubt. Beyond two or three tiny flecks of gold the three adventurers found nothing of value in the deeper sand and gravel of the stream. That night absolute dejection settled on the camp. Both Rod and Wabigoon made vain efforts to liven up their drooping spirits. Only Mukoki, to whom gold carried but a fleeting and elusive value, was himself, and even his hopefulness was dampened by the gloom of his companions. Rod could see but one explanation of their failure. Somewhere near the cataract John Ball and the Frenchmen had found a rich pocket of gold, and they had worked it out, probably before the fatal tragedy in the old cabin.

"But how about the mad hunter and his golden bullets?" insisted Wabi, in another effort to brighten their prospects. "The bullets weighed an ounce each, and I'll stake my life they came from this chasm. He knows where the gold is, if we don't!"

"Come back soon!" grunted Mukoki. "Watch heem. Fin' gol'!"

"That's what we'll do!" cried the young Indian, jumping suddenly to his feet and toppling Rod backward off the rock upon which he was sitting. "Come, cheer up, Rod! The gold is here, somewhere, and we're going to find it! I'm heartily ashamed of you; you, whom I thought would never get discouraged!"

Rod was laughing when he recovered from the playful mauling which Wabi administered before he could regain his feet.

"That's right, I deserve another licking! We've got all the spring and summer before us, and if we don't find the gold by the time snow flies we'll come back and try it again next year! What do you say?"

"And bring Minnetaki with us!" added Wabi, jumping into the air and kicking his heels together. "How will you like that, Rod?" He nudged his comrade in the ribs, and in another moment both were puffing and laughing in one of their good-natured wrestling bouts, in which the cat-like agility of the young Indian always won for him in the end.

In spite of momentary times like this, when the natural buoyancy and enthusiasm of the young adventurers rose above their discouragement, the week that followed added to their general depression. For miles the chasm was explored and at the end of the week they had found less than an ounce of gold. If their pans had given them no returns at all their disappointment would have been less, for then, as Wabi said, they could have given up the ghost with good grace. But the few precious yellow grains which they found now and then lured them on, as these same grains have lured other hundreds and thousands since the dawn of civilization. Day after day they persisted in their efforts; night after night about their camp-fire they inspired each other with new hope and made new plans. The spring sun grew stronger, the poplar buds burst into tiny leaf and out beyond the walls of the chasm the first promises of summer came in the sweetly scented winds of the south, redolent with the breath of balsam and pine and the thousand growing things of the plains.

But at last the search came to an end. For three days not even a grain of gold had been found. Around the big rock, where they were eating dinner, Rod and his friends came to a final conclusion. The following morning they would break camp, and leaving their canoe behind, for the creek was now too shallow for even birch-bark navigation, they would continue their exploration of the chasm in search of other adventures. The whole summer was ahead of them, and though they had failed in discovering a treasure where John Ball and the Frenchmen had succeeded, they might find one farther on. At least the trip deeper into the unexplored wilderness would be filled with excitement.

Mukoki rose to his feet, leaving Rod and Wabi still discussing their plans. Suddenly he turned toward them, and a startled cry fell from his lips, while with one long arm he pointed beyond the fall into the upper chasm.

"Listen—heem—heem!"

The old warrior's face twitched with excitement, and for a full half minute he stood motionless, his arm still extended, his black eyes staring steadily at Rod and Wabigoon who sat as silent as the rocks about them. Then there came to them from a great distance a quavering, thrilling sound, a sound that filled them again with the old horror of the upper chasm—the cry of the mad hunter.

At that distant cry Wabigoon sprang to his feet, his eyes leaping fire, his bronzed cheeks whitening in an excitement even greater than that of Mukoki.

"Muky, I told you!" he cried. "I told you!" The young Indian's body quivered, his hands were clenched, and when he turned upon Rod the white youth was startled by the look in his face.

"Rod, John Ball is coming back to his gold!"

Hardly had he spoken the words when the tenseness left his body and his hands dropped to his side.

The words shot from him before he could control himself enough to hold them back. In another moment he was sorry. The thought that John Ball and the mad hunter were the same person he had kept to himself, until for reasons of his own he had let Mukoki into his secret. While the idea had taken larger and larger growth in his mind he knew that from every logical point of view the thing was impossible, and that constraint which came of the Indian blood in him held him from discussing it with Rod. But now the words were out. A quick flush replaced the whiteness that had come into his face. In another instant he was leaning eagerly toward Rod, his eyes kindling into fire again. He had not expected the change that he now saw come over the white youth.

"I have been thinking that for a long time," he continued. "Ever since we found the footprints in the sand. There's just one proof that we need, just one, and—"

"Listen!"

Rod fairly hissed the word as he held up a warning hand.

This time the cry of the mad hunter came to them more distinctly. He was approaching through the upper chasm!

The white youth rose to his feet, his eyes steadily fixed upon Wabigoon's. His face was deathly pale.

"John Ball!" he repeated, as if he had just heard what the other had said. "John Ball!" What seemed to him to be the only truth swept upon him like a flood, and for a score of seconds, in every one of which he could hear his heart thumping excitedly, he stood like one stunned. John Ball! John Ball returned to life to find their gold for them, to tell them of the tragedy and mystery of those days long dead and gone! Like powder touched by a spark of fire his imagination leaped at Wabi's thrilling suggestion.

Mukoki set to work.

"Hide!" he exclaimed. "Hide thees—thees—thees!" He pointed about him at all the things in camp.

Both of the boys understood.

"He must see no signs of our presence from the top of the fall!" cried Wabi, gathering an armful of camp utensils. "Hide them back among the cedars!"

Mukoki hurried to the cedar bough shelter and began tearing it down. For five minutes the adventurers worked on the run. Once during that time they heard the madman's wailing cry, and hardly had they finished and concealed themselves in the gloom of the old cabin when it came again, this time from not more than a rifle-shot's distance beyond the cataract. It was not a scream that now fell from the mad hunter's lips, but a low wail and in it there was something that drove the old horror from the three wildly beating hearts and filled them with a measureless, nameless pity. What change had come over the madman? The cry was repeated every few seconds now, each time nearer than before, and in it there was a questioning, appealing note that seemed to end in sobbing despair, a something that gripped at Rod's heart and filled him with a great half-mastering impulse to answer it, to run out and stretch his hands forth in greeting to the strange, wild creature coming down the chasm!

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!

Wabi and Mukoki had seen the desperate leap and the young Indian was beside the pool before Rod had recovered from his horrified astonishment. For centuries the water of the chasm stream had been tumbling into this pool wearing it deeper and deeper each year, until the water in it was over a man's head. In width it was not more than a dozen feet.

"Watch for him! He'll drown if we don't get him out," shouted Wabi.

Rod leaped to the edge of the pool, with Mukoki between him and Wabigoon. Ready to spring into the cold depths at the first sign of the old man's gray head or struggling arms the three stood with every muscle ready for action. A second, two seconds, five seconds passed, and there was no sign of him. Rod's heart began to beat with drum-like fierceness. Ten seconds! A quarter of a minute! He looked at Wabigoon. The young Indian had thrown off his caribou-skin coat; his eyes, as he turned them for a moment toward Rod, flashed back the white youth's fear.

"I'm going to dive for him!"

In another instant he had plunged head foremost into the pool. Mukoki's coat fell to the ground. He crouched forward until it seemed he must topple from the stone upon which he stood. Another fifteen seconds and Wabigoon's head appeared above the water, and the old warrior gave a shout.

"Me come!"

He shot out and disappeared in a huge splash close to Wabi. Rod stood transfixed, filled with a fear that was growing in him at every breath he drew. He saw the convulsions of the water made by the two Indians, who were groping about below the surface. Wabigoon came up again for breath, then Mukoki. It seemed to him that an age had passed, and he felt no hope. John Ball was dead!

Not for a moment now did he doubt the identity of the mad hunter. The strange, wistful light that had replaced the glare in the old man's eyes when he heard his own name called to him had spoken more than words. It was John Ball! And he was dead! For a third time, a fourth, and a fifth Mukoki and Wabigoon came up for air, and the fifth time they dragged themselves out upon the rocks that edged the pool. Mukoki spoke no word but ran back to the camp and threw a great armful of dry fuel upon the fire. Wabigoon still remained at the edge of the pool, dripping and shivering. His hands were clenched, and Rod could see that they were filled with sand and gravel. Mechanically the Indian opened his fingers and looked at what he had unconsciously brought up from under the fall.
