and Rod hung back in soundless suspense. Half an hour later Mukoki straightened himself, rose to his feet and held out the precious film to Rod.
As tenderly as though his own life depended upon its care, Rod held the piece of birch, now a silken, almost transparent sheet, between himself and the light. A cry welled up into his throat. It was repeated by Wabi. And then there was silence—a silence broken only by their bated breaths and the excited thumpings of their hearts.
As though they had been written but yesterday, the mysterious words on the map were disclosed to their eyes. Where Rod had made out only three letters there were now plainly discernible the two words "third waterfall," and very near to these was the word "cabin." Below them were several lines, clearly impressed in the birch film. Slowly, his voice trembling, Rod read them to his companions.
"We, John Ball, Henri Langlois, and Peter Plante, having discovered gold at this fall, do hereby agree to joint partnership in the same, and do pledge ourselves to forget our past differences and work in mutual good will and honesty, so help us God. Signed,
"JOHN BALL, HENRI LANGLOIS, PETER PLANTE."
At the very top of the map the impression of several other words caught Rod's eyes. They were more indistinct than any of the others, but one by one he made them out. A hot blurring film seemed to fall over his eyes and he felt as though his heart had suddenly come up into his throat. Wabi's breath was burning against his cheek, and it was Wabi who spoke the words aloud.
"Cabin and head of chasm."
Rod went back to the table and sat down, the precious bit of birch-bark under his hand. Mukoki, standing mute, had listened and heard, and was as if stunned by their discovery. But now his mind returned to the moose steak, and he placed it on the stove. Wabi stood with his hands in his pockets, and after a little he laughed a trembling, happy laugh.
"Well, Rod, you've found your mine. You are as good as rich!"
"You mean that we have found our mine," corrected the white youth. "We are three, and we just naturally fill the places of John Ball, Henri Langlois and Peter Plante. They are all dead. The gold is ours!"
Wabi had taken up the map.
"I can't see the slightest possibility of our not finding it," he said. "The directions are as plain as day. We follow the chasm, and somewhere in that chasm we come to a waterfall. A little beyond this the creek that runs through the gorge empties into a larger stream, and we follow this second creek or river until we come to the third fall. The cabin is there, and the gold can not be far away."
He had carried the map to the door again, and Rod joined him.
"There is nothing that gives us an idea of distance on the map," he continued. "How far did you travel down the chasm?"
"Ten miles, at least," replied Rod.
"And you discovered no fall?"
"No."
With a splinter picked up from the floor Wabi measured the distances between the different points on the diagram.
"There is no doubt but what this map was drawn by John Ball," he said after a few moments of silent contemplation. "Everything points to that fact. Notice that all of the writing is in one hand, except the signatures of Langlois and Plante, and you could hardly decipher the letters in those signatures if you did not already know their names from this writing below. Ball wrote a good hand, and from the construction of the agreement over the signatures he was a man of pretty fair education. Don't you think so? Well, he must have drawn this map with some idea of distance in his mind. The second fall is only half as far from the first fall as the third fall is from the second, which seems to me conclusive evidence of this. If he had not had distance in mind he would not have separated the falls in this way on the map."
"Then if we can find the first fall we can figure pretty nearly how far the last fall is from the head of the chasm," said Rod.
"Yes. I believe the distance from here to the first fall will give us a key to the whole thing."
Rod had produced a pencil from one of his pockets and was figuring on the smooth side of a chip.
"The gold is a long way from here at the best, Wabi. I explored the chasm for ten miles. Say that we find the first fall within fifteen miles. Then, according to the map, the second fall would be about twenty miles from the first, and the third forty miles from the second. If the first fall is within fifteen miles of this cabin the third fall is at least seventy-five miles away."
Wabi nodded.
"But we may not find the first fall within that distance," he said. "By George—" He stopped and looked at Rod with an odd look of doubt in his face. "If the gold is seventy-five or a hundred miles away, why were those men here, and with only a handful of nuggets in their possession? Is it possible that the gold played out—that they found only what was in the buckskin bag?"
"If that were so, why should they have fought to the death for the possession of the map?" argued Rod.
Mukoki was turning the steak. He had not spoken, but now he said:
"Mebby going to Post for supplies."
"That's exactly what they were doing!" shouted the Indian youth. "Muky, you have solved the whole problem. They were going for supplies. And they didn't fight for the map—not for the map alone!"
His face flushed with new excitement.
"Perhaps I am wrong, but it all seems clear to me now," he continued. "Ball and the two Frenchmen worked their find until they ran out of supplies. Wabinosh House is over a hundred years old, and fifty years ago that was the nearest point where they could get more. In some way it fell to the Frenchmen to go. They had probably accumulated a hoard of gold, and before they left they murdered Ball. They brought with them only enough gold to pay for their supplies, for it was their purpose not to arouse the suspicion of any adventurers who happened to be at the Post. They could easily have explained their possession of those few nuggets. In this cabin either Langlois or Plante tried to kill his companion, and thus become the sole possessor of the treasure, and the fight, fatal to both, ensued. I may be wrong, but—by George, I believe that is what happened!"
"And that they buried the bulk of their gold somewhere back near the third fall?"
"Yes; or else they brought the gold here and buried it somewhere near this very cabin!"
They were interrupted by Mukoki.
"Dinner ready!" he called.
CHAPTER XIII
SNOWED IN
Until the present moment Rod had forgotten to speak of the mysterious man-trail he had encountered in the chasm. The excitement of the past hour had made him oblivious to all other things, but now as they ate their dinner he described the strange maneuvers of the spying Woonga. He did not, however, voice those fears which had come to him in the gorge, preferring to allow Mukoki and Wabigoon to draw their own conclusions. By this time the two Indians were satisfied that the Woongas were not contemplating attack, but that for some unaccountable reason they were as anxious to evade the hunters as the hunters were to evade them. Everything that had passed seemed to give evidence of this. The outlaw in the chasm, for instance, could easily have waylaid Rod; a dozen times the almost defenseless camp could have been attacked, and there were innumerable places where ambushes might have been laid for them along the trap-lines.
So Rod's experience with the Woonga trail between the mountains occasioned little uneasiness, and instead of forming a scheme for the further investigation of this trail on the south, plans were made for locating the first fall. Mukoki was the swiftest and most tireless traveler on snow-shoes, and it was he who volunteered to make the first search. He would leave the following morning, taking with him a supply of food, and during his absence Rod and Wabigoon would attend to the traps.
"We must have the location of the first fall
