"Aren't you going to look in the pack?"
Wabi turned and gazed at his companion with a half-curious hesitating smile.
"Anything in it?" he asked suspiciously.
"See here, boys," cried Rod, forgetting himself in his suppressed enthusiasm. "I said there was a treasure in that chasm, and there was. I found it. You are welcome to look into that pack if you wish!"
Wabi dropped the knife with which he was cutting the bread and went to the pack. He touched it with the toe of his boot, lifted it in his hands, and glanced at Rod again.
"It isn't a joke?" he asked.
"No."
Rod turned his back upon the scene and began to take off his coat as coolly as though it were the commonest thing in the world for him to bring silver foxes into camp. Only when Wabi gave a suppressed yell did he turn about, and then he found the Indian standing erect and holding out the silver to the astonished gaze of Mukoki.
"Is it a good one?" he asked.
"A beauty!" gasped Wabi.
Mukoki had taken the animal and was examining it with the critical eyes of a connoisseur.
"Ver' fine!" he said. "At Post heem worth fi' hundred dollars—at Montreal t'ree hundred more!"
Wabi strode across the cabin and thrust out his hand.
"Shake, Rod!"
As the two gripped hands he turned to Mukoki.
"Bear witness, Mukoki, that this young gentleman is no longer a tenderfoot. He has shot a silver fox. He has done a whole winter's work in one day. I take off my hat to you, Mr. Drew!"
Roderick's face reddened with a flush of pleasure.
"And that isn't all, Wabi," he said. His eyes were filled with a sudden intense earnestness, and in the strangeness of the change Wabi forgot to loosen the grip of his fingers about his companion's hand.
"You don't mean that you found—"
"No, I didn't find gold," anticipated Rod. "But the gold is there! I know it. And I think I have found a clue. You remember that when you and I examined the skeleton against the wall we saw that it clutched something that looked like birch-bark in its hand? Well, I believe that birch-bark holds the key to the lost mine!"
Mukoki had come beside them and stood listening to Rod, his face alive with keen interest. In Wabi's eyes there was a look half of doubt, half of belief.
"It might," he said slowly. "It wouldn't do any harm to see."
He stepped to the stove and took off the partly cooked steak. Rod slipped on his coat and hat and Mukoki seized his belt-ax and the shovel. No words were spoken, but there was a mutual understanding that the investigation was to precede dinner. Wabi was silent and thoughtful and Rod could see that his suggestion had at least made a deep impression upon him. Mukoki's eyes began to gleam again with the old fire with which he had searched the cabin for gold.
The skeletons were buried only a few inches deep in the frozen earth in the edge of the cedar forest, and Mukoki soon exposed them to view. Almost the first object that met their eyes was the skeleton hand clutching its roll of birch-bark. It was Rod who dropped upon his knees to the gruesome task.
With a shudder at the touch of the cold bones he broke the fingers back. One of them snapped with a sharp sound, and as he rose with the bark in his hand his face was bloodlessly white. The bones were covered again and the three returned to the cabin.
Still silent, they gathered about the table. With age the bark of the birch hardens and rolls itself tightly, and the piece Rod held was almost like thin steel. Inch by inch it was spread out, cracking and snapping in brittle protest. The hunters could see that the bark was in a single unbroken strip about ten inches long by six in width. Two inches, three, four were unrolled—and still the smooth surface was blank. Another half-inch, and the bark refused to unroll farther.
"Careful!" whispered Wabi.
With the point of his knife he loosened the cohesion.
"I guess—there's—nothing—" began Rod.
Even as he spoke he caught his breath. A mark had appeared on the bark, a black, meaningless mark with a line running down from it into the scroll.
Another fraction of an inch and the line was joined by a second, and then with an unexpectedness that was startling the remainder of the roll released itself like a spring—and to the eyes of the three wolf hunters was revealed the secret of the skeleton hand.
Spread out before them was a map, or at least what they at once accepted as a map, though in reality it was more of a crude diagram of straight and crooked lines, with here and there a partly obliterated word to give it meaning. In several places there were mere evidences of words, now entirely illegible. But what first held the attention of Rod and his companions were several lines in writing under the rough sketch on the bark, still quite plain, which formed the names of three men. Roderick read them aloud.
"John Ball, Henri Langlois, Peter Plante."
Through the name of John Ball had been drawn a broad black line which had almost destroyed the letters, and at the end of this line, in brackets, was printed a word in French which Wabi quickly translated.
"Dead!" he breathed. "The Frenchmen killed him!"
The words shot from him in hot excitement.
Rod did not reply. Slowly he drew a trembling finger over the map. The first word he encountered was unintelligible. Of the next he could only make out one letter, which gave him no clue. Evidently the map had been made with a different and less durable substance than that with which the names had been written. He followed down the first straight black line, and where this formed a junction with a wider crooked line were two words quite distinct:
"Second waterfall."
Half an inch below this Rod could make out the letters T, D and L, widely scattered.
"That's the third waterfall," he exclaimed eagerly.
At this point the crude lines of the diagram stopped, and immediately below, between the map and the three names, it was evident that there had been considerable writing. But not a word of it could the young hunters make out. That writing, without doubt, had given the key to the lost gold. Rod looked up, his face betraying the keenness of his disappointment. He knew that under his hand he held all that was left of the secret of a great treasure. But he was more baffled than ever. Somewhere in this vast desolation there were three waterfalls, and somewhere near the third waterfall the Englishman and the two Frenchmen had found their gold. That was all he knew. He had not found a waterfall in the chasm; they had not discovered one in all their trapping and hunting excursions.
Wabi was looking down into his face in silent thought. Suddenly he reached out and seized the sheet of bark and examined it closely. As he looked there came a deeper flush in his face, his eyes brightened and he gave a cry of excitement.
"By George, I believe we can peel this!" he cried. "See here, Muky!" He thrust the birch under the old Indian's eyes. Even Mukoki's hands were trembling.
"Birch-bark is made up of a good many layers, each as thin as the thinnest paper," he explained to Rod as Mukoki continued his examination. "If we can peel off that first layer, and then hold it up to the light, we shall be able to see the impression of every word that was ever made on it—even though they were written a hundred years ago!"
Mukoki had gone to the door, and now he turned, grinning exultantly.
"She peel!"
He showed them where he had stripped back a corner of the film-like layer. Then he sat down in the light, his head bent over, and for many minutes he worked at his tedious task while Wabi and Rod hung back in soundless suspense.
