cabin in which they had passed their hunting season, and close to this was the pack which Mukoki had dropped there the night before. No one had molested it. Wabi's face relaxed. Rod, breathing easier, laughed softly. What had there been to fear? He glanced questioningly at Mukoki.
"There rocks, there tree," said the old warrior, in answer to Rod's glance, "down there went scream!" He pointed far out across the plain.
Wabi had gone to the tree.
"See here, Rod!" he cried. "By George, this was a close shave!" He pointed to a tiny hole freshly made in the smooth white surface of the tree as the others came up. "There—stand there, Mukoki, back to the tree, as you said you were when the shot was fired. Great Caesar, that fellow had a dead line on your head—two inches high! No wonder it made you think the scream of a lynx was something else!"
"No lynx," said Mukoki, his face darkening.
"Shame on you, Muky!" laughed Wabigoon. "Don't get angry. I won't say it again if it makes you mad."
Rod had drawn his hunting-knife and was prodding the point of it in the bullet hole.
"I can feel the ball," he said. "It's not in more than an inch."
"That's curious," exclaimed Wabigoon, coming close beside him. "It ought to be half-way through the tree at least! Eh, Muky? I don't believe it would have hurt—"
He stopped. Rod had turned with a sudden excited cry. He held out his knife, tip upward, and pointed to it with the index finger of his free hand. Wabi's eyes fell on the tip of the blade. Mukoki stared. For a full half minute the three stood in speechless amazement. Clinging to the knife tip was a tiny fleck of yellow, gleaming lustrously in the sun as Rod slowly turned the handle of his weapon.
"Another—gold—bullet!"
The words fell from Wabi's lips very slowly, and so low that they were scarce above a whisper. Mukoki seemed to have ceased breathing. Rod's eyes met the old warrior's.
"What does it mean?"
Wabi had pulled his knife and was digging into the tree. A few deep cuts and the golden bullet lay exposed to view.
"What does it mean?" repeated the white youth.
Again he addressed his question to Mukoki.
"Man who shoot bear—heem no dead," replied the old pathfinder. "Same gun, same gold, same—"
"Same what?"
A strange gleam came for an instant into Mukoki's eyes, and without finishing he turned and pointed across the narrow plain that lay between them and the mysterious chasm which they were to follow in their search for treasure.
"Cry went there!" he said shortly.
"To the chasm!" said Wabi.
"To the chasm!" repeated Rod.
Impelled by the same thought the three adventurers went toward the rocks from which the shot had been fired. Surely they would discover some sign there, or lower down upon the plain, where the melting snows had softened the earth. Mukoki led in the search, and foot by foot they examined the spot where the mysterious marksman must have stood when he sent his golden bullet so close to the Indian's head.
But not a trace of his presence had he left behind. Working abreast, the three began the descent of the ridge. Hardly had they covered a third of the distance to the plain when Wabi, who was trailing between Rod and the old Indian, called out that he had made a discovery. Mukoki had already reached him when Rod came up, and the two were gazing silently at something fluttering from a bush.
"Lynx hair!" cried Rod. "A lynx has been this way!" He could not entirely conceal the triumph in his voice. He had been right in his conjecture of the night before, the cry that had frightened Mukoki had been made by a lynx!
"Yes, a lynx has been this way, a lynx four feet high," said Wabigoon quietly, and the touch of raillery in his voice assured Rod that he had still other lessons to learn in the life of this big wilderness. "Lynx don't grow that big, Rod!"
"Then it's—" Rod feared to go on.
"Lynx fur. That's just what it is. Whoever fired at Mukoki last night was dressed in skins! Now, can you tell us what that means?"
Without waiting for an answer Wabigoon resumed his search. But the mountain side gave no further evidence. Not a footprint was found upon the plain. If the mysterious person who had fired the golden bullet had leaped from the mountain top into space he could have left no fewer traces behind him. At the end of an hour Rod and his companions returned to the canoe, carried their loads to the pack in the dip, and prepared dinner. Their suspense and fear, and specially Mukoki's dread, were in a large measure gone. But at the same time they were more hopelessly mystified than ever. That there was danger ahead of them, that the menace of golden bullets was actual and thrilling, all three were well agreed, but the sunlight of day and a little sound reasoning had dispelled their half superstitious terrors of the previous night and they began to face the new situation with their former confidence.
"We can't let this delay us," said Wabi, as they ate their dinner. "By night we ought to be in our old camp at the head of the chasm, where we held the Woongas at bay last winter. The sooner we get out of the way of these golden bullets the better it will be for us!"
Mukoki shrugged his shoulders.
"Gold bullet follow, I guess so," he grunted, "Cry went there—to chasm!"
"I don't believe this fellow, whoever he is, will hang to our trail," continued Wabi, giving Rod a suggestive look. A few moments later he found an opportunity to whisper, "We've got to get that cry out of Muky's head, Rod, or we'll never find our gold!"
When Mukoki had gone to arrange his pack the young Indian spoke earnestly to his companion.
"Muky isn't afraid of bullets, either gold or lead; he isn't afraid of any danger on earth. But that cry haunts him. He is trying not to let us know, yet it haunts him just the same. Do you know what he is thinking? No? Well, I do! He is superstitious, like the rest of his race, and the two gold bullets, the terrible cries, and the fact that we found no tracks upon the plain are all carrying him toward one conclusion, that the strange thing that fired at him is—"
Wabigoon paused and wiped his face, and it was easy for Rod to see that he was suppressing some unusual excitement.
"What does he think it is?"
"I'm not sure, not quite sure, yet," went on the Indian youth. "But listen! It is a legend in Mukoki's tribe, and always has been, that once in every so many generations they are visited by a terrible warrior sent by the Great Spirit who takes sacrifice of them, a sacrifice of human life, because of a great wrong that was once done by their people. And this warrior, though invisible, has a voice that makes the mountains quake and the rivers stand still with fear, and in his great bow he shoots shafts that are made of gold! Do you understand? Last night I heard Mukoki talking about it in his sleep. Either we must hear this cry, and find out more about it, or hurry to a place where it won't be heard again. Golden bullets and cries and Mukoki's superstitions are going to be worse than Woongas if we don't watch out!"
"But the whole thing is as plain as day!" declared Rod in astonishment. "A man shot at the bear, and the same man shot at Mukoki, and he fired gold each time. Surely—"
"It's
