convulsed under foot; volumes of dense black smoke shot upward, shutting the mountain in an impenetrable pall of gloom; and in an instant these rolling, twisting volumes of black became lurid, and an explosion like that of a thousand great guns rent the air. As fast as the eye could follow, sheets of flame shot out of the sea of smoke, climbing higher and higher, in lightning flashes, until the lurid tongues licked the air a quarter of a mile above the startled wilderness. Explosion followed explosion, some of them coming in hollow, reverberating booms, others sounding as if in mid-air. The heavens were filled with hurtling rocks; solid masses of granite ten feet square were thrown a hundred feet away; rocks weighing a ton were hurled still farther, as if they were no more than stones flung by the hand of a giant; chunks that would have crashed from the roof to the basement of a sky-scraper dropped a third and nearly a half a mile away. For three minutes the frightful convulsions continued. Then the lurid lights died out of the pall of smoke, and the pall itself began to settle. Howland felt a grip on his arm. Dumbly he turned and looked into the white, staring face of the superintendent. His ears tingled, every fiber in him seemed unstrung. MacDonald's voice came to him strange and weird.
"What do you think of that, Howland?" The two men gripped hands, and when they looked again they saw dimly through dust and smoke only torn and shattered masses of rock where had been the giant ridge that barred the path of the new road to the bay.
Howland talked but little on their way back to camp. The scene that he had just witnessed affected him strangely; it stirred once more within him all of his old ambition, all of his old enthusiasm, and yet neither found voice in words. He was glad when the dinner was over at Thorne's, and with the going of the mail sledge and the senior engineer there came over him a still deeper sense of joy. Now he was in charge, it was his road from that hour on. He crushed MacDonald's hand in a grip that meant more than words when they parted. In his own cabin he threw off his coat and hat, lighted his pipe, and tried to realize just what this all meant for him. He was in charge--in charge of the greatest railroad building job on earth--he, Jack Howland, who less than twenty years ago was a barefooted, half-starved urchin peddling papers in the streets where he was now famous! And now what was this black thing that had come up to threaten his chances just as he had about won his great fight? He clenched his hands as he thought again of what had already happened--the cowardly attempt on his life, the warnings, and his blood boiled to fever heat. That night--after he had seen Meleese--he would know what to do. But he would not be driven away, as Gregson and Thorne had been driven. He was determined on that.
The gloom of night falls early in the great northern mid-winter, and it was already growing dusk when there came the sound of a voice outside, followed a moment later by a loud knock at the door. At Howland's invitation the door opened and the head and shoulders of a man appeared.
"Something has gone wrong out at the north coyote, sir, and Mr. MacDonald wants you just as fast as you can get out there," he said. "He sent me down for you with a sledge."
"MacDonald told me the thing was ready for firing," said Howland, putting on his hat and coat. "What's the matter?"
"Bad packing, I guess. Heard him swearing about it. He's in a terrible sweat to see you."
Half an hour later the sledge drew up close to the place where Howland had seen a score of men packing bags of powder and dynamite earlier in the day. Half a dozen lanterns were burning among the rocks, but there was no sign of movement or life. The engineer's companion gave a sudden sharp crack of his long whip and in response to it there came a muffled halloo from out of the gloom.
"That's MacDonald, sir. You'll find him right up there near that second light, where the coyote opens up. He's grilling the life out of half a dozen men in the chamber, where he found the dynamite on top of the powder instead of under it."
"All right!" called back Howland, starting up among the rocks. Hardly had he taken a dozen steps when a dark object shot out behind him and, fell with crushing force on his head. With, a groaning cry he fell forward on his face. For a few moments he was conscious of voices about him; he knew that he was being lifted in the arms of men, and that after a time they were carrying him so that his feet dragged on the ground. After that he seemed to be sinking down--down--down--until he lost all sense of existence in a chaos of inky blackness.
CHAPTER VIII
THE HOUR OF DEATH
A red, unwinking eye staring at him fixedly from out of impenetrable gloom--an ogreish, gleaming thing that brought life back into him with a thrill of horror--was Howland's first vision of returning consciousness. It was dead in front of him, on a level with his face--a ball of yellow fire that seemed to burn into his very soul. He tried to cry out, but no sound fell from his lips; he strove to move, to fight himself away, but there was no power of movement in his limbs. The eye grew larger. He saw that it was so bright it cast a halo, and the halo widened before his own staring eyes until the dense gloom about it seemed to be melting away. Then he knew. It was a lantern in front of him, not more than ten feet away. Consciousness flooded him, and he made another effort to cry out, to free his arms from an invisible clutch that held him powerless. At first he thought this was the clutch of human hands; then as the lantern-light revealed more clearly the things about him and the outlines of his own figure, he saw that it was a rope, and he knew that he was unable to cry out because of something tight and suffocating about his mouth.
The truth came to him swiftly. He had come up to the coyote on a sledge. Some one had struck him. He remembered that men had half-dragged him over the rocks, and these men had bound and gagged him, and left him here, with the lantern staring him in the face. But where was he? He shifted his eyes, straining to penetrate the gloom. Ahead of him, just beyond the light, there was a black wall; he could not move his head, but he saw where that same wall closed in on the left. He turned his gaze upward, and it ended with that same imprisoning barrier of rock. Then he looked down, and the cry of horror that rose in his throat died in a muffled groan. The light fell dimly on a sack--two of them--three--a tightly packed wall of them.
He knew now what had happened. He was imprisoned in the coyote, and the sacks about him were filled with powder. He was sitting on something hard--a box--fifty pounds of dynamite! The cold sweat stood out in beads on his face, glistening in the lantern-glow. From between his feet a thin, white, ghostly line ran out until it lost itself in the blackness under the lantern. It was the fuse, leading to the box of dynamite on which he was sitting!
Madly he struggled at the thongs that bound him until he sank exhausted against the row of powder sacks at his back. Like words of fire the last warning of Meleese burned in his brain--"You must go, to-morrow--to-morrow--or they will kill you!" And this was the way in which he was to die! There flamed before his eyes the terrible spectacle which he had witnessed a few hours before--the holocaust of fire and smoke and thunder that had disrupted a mountain, a chaos of writhing, twisting fury, and in that moment his heart seemed to cease its beating. He closed his eyes and tried to calm himself. Was it possible that there lived men so fiendish as to condemn him to this sort of death? Why had not his enemies killed him out among the rocks? That would have been easier--quicker--less troublesome. Why did they wish to torture him? What terrible thing had he done? Was he mad--mad--and this all a terrible nightmare, a raving find unreal contortion of things in his brain? In this hour of death question after question raced through his head, and he answered no one of them. He sat still for a time, scarcely breathing. There was no sound, save the beating of his own heart. Then there came another, almost unheard at first, faint, thrilling, maddening.
Tick--tick--tick!
It was the beating of his watch. A spasm of horror seized him.
What time was it? The coyote was to be fired at nine o'clock. It was four when
