The sun passed slowly up the arch of the heavens. The morning coolness had gone long since from the air, but the foliage of the great forest protected them. Often, when the shade was not so dense they ran over smooth, springy turf, and they were even deliberate enough, as the hours passed, to eat a little food from their packs. Twice they knelt and drank at the brooks.
They made no attempt to conceal their trail, knowing that it was useless, but Henry and Shif'less Sol, their rifles always lying in the hollows of their arms, never failed to seek a glimpse of the relentless hound. It was fully noon when the character of the country began to change slightly. The hills were a little higher and there was more underbrush. Just as they reached a crest Henry looked back. In the far bushes, he saw a long dark form and a pointed gray head with glittering eyes. He knew that it was the great dog, a wolf hound; he was sure now, and, quick as a flash, he raised his rifle and fired at a point directly between the glittering eyes. The dog dropped out of sight and the five ran on.
"Do you think you killed him, Henry?" asked Shif'less Sol breathlessly.
"I don't know; I hope so."
Behind them rose a deep bay, the trailing note of the great dog, but now it seemed more ferocious and uncanny than ever. Shif'less Sol shuddered. Tom Ross' face turned not pale, but actually white, through its many layers of tan.
"Henry," said Shif'less Sol, "I never knowed you to miss at that range afore."
The eyes of the two met again and each asked a question of the other.
"I think I was careless, Sol," said Henry. His voice shook a little.
"I hope so," said Shif'less Sol, whose mind was veering more and more toward the belief of Tom Ross, "but I'd like pow'ful well to put a bullet through that animal myself. Them awful wolf howls o' his hit on my nerves, they do."
The chance of the shiftless one came presently. He, too, saw among the bushes the long dark body, the massive pointed head and the glittering eyes. He fired as quickly as Henry had done. Then came that silence, followed in a few minutes by the deep and sinister baying note of the great hound.
"I reckon I fired too quick, too," said Shif'less Sol. But the hands that grasped his rifle were damp and cold.
"'Tain't no use," said Tom Ross in a tone of absolute conviction. "I've seen you and Henry fire afore at harder targets than that, an' hit 'em every time. You hit this one, too."
"Then why didn't we kill the brute?" exclaimed Henry.
"'Cause lead wuzn't meant to kill him. Your bullets went right through him an' never hurt him."
Henry forced a laugh.
"Pshaw, Tom," he said. "Don't talk such foolishness.'"
"I never talked solider sense in my life," said Ross.
Henry and Shif'less Sol reloaded their rifles as they ran, and both were deeply troubled. In all their experience of every kind of danger they had met nothing so sinister as this, nothing so likely to turn the courage of a brave man. Twice sharpshooters who never missed had missed a good target. Or could there be anything in the words of Tom Ross?
They left the warriors some distance behind again and paused for another rest, until the terrible hound should once more bring the pursuers near. All five were much shaken, but Tom Ross as usual in these intervals turned his back upon the others, and began to work with his hunting knife. Henry, as he drew deep breaths of fresh air into his lungs, noticed that the sun was obscured. Many clouds were coming up from the southwest, and there was a damp touch in the air. The wind was rising.
"Looks as if a storm was coming," he said. "It ought to help us."
But Tom Ross solemnly shook his head.
"It might throw off the warriors," he said, "but not the dog. Hark, don't you hear him again?"
They did hear. The deep booming note, sinister to the last degree, came clearly to their ears.
"It's time to go ag'in," said Shif'less Sol, with a wry smile. "Seems to me this is about the longest footrace I ever run. Sometimes I like to run, but I like to run only when I like it, and when I don't like it I don't like for anybody to make me do it. But here goes, anyhow. I'll keep on runnin' I don't know whar."
Sol's quaint remarks cheered them a little, and their feet became somewhat lighter. But one among them was thinking with the utmost concentration. Tom Ross, convinced that something was a fact, was preparing to meet it. He would soon be ready. Meanwhile the darkness increased and the wind roared, but there was no rain. The country grew rougher. The underbrush at times was very dense, and one sharp little stony hill succeeded another. The running was hard.
Henry was growing angry. He resented this tenacious pursuit. It had been so unexpected, and the uncanny dog had been so great a weapon against them. He began to feel now that they had run long enough. They must make a stand and the difficult country would help them.
"Boys," he said, "we've run enough. I'm in favor of dropping down behind these rocks and fighting them off. What do you say?"
All were for it, and in a moment they took shelter. The heavy clouds and the forest about them made the air dim, but their eyes were so used to it that they could see anyone who approached them, and they were glad now that they had decided to put the issue to the test of battle. They lay close together, watching in front and also for a flank movement, but for a while they saw nothing. The hound had ceased to bay, but, after a while, both Henry and Sol saw a rustling among the bushes, and they knew that the savages were at hand.
But of all the watchers at that moment Silent Tom Ross was the keenest. He also occupied himself busily for a minute or so in drawing the bullet from his rifle. Henry did not notice him until this task was almost finished.
"Why, in the name of goodness, Tom," he exclaimed, "are you unloading your rifle at such a time?"
Tom looked up. The veteran scout's eyes shone with grim fire.
"I know what I'm doin'," he said. "Mebbe I'm the only one in this crowd who knows what ought to be did. I'm not unloadin' my rifle, Henry. I'm jest takin' out one bullet an' puttin' in another in its place. See this?"
He held up a small disc that gleamed in the dim light.
"That," said Tom, "is a silver bullet. It's flat an' it ain't shaped like a bullet, but it's a bullet all the same. I've been cuttin' it out uv a silver sixpence, an' now it exactly fits my rifle. You an' Sol—an' I ain't sayin' anything ag'in' your marksmanship—could shoot at that dog all day without hurtin' him, but I'm goin' to kill him with this silver bullet."
"Don't talk foolishness, Tom," said Henry.
"You'll see," said the veteran in a tone of such absolute conviction that the others could not help being impressed. Tom curled himself up behind one rock, and in front of another. Then he watched with the full intensity that the danger and his excitement demanded. He felt that all depended upon him, his own life and the lives of those four comrades so dear to him.
Tom Ross, silent, reserved, fairly poured his soul into his task. Nothing among the bushes and trees in front of them escaped his attention. Once he saw a red feather move, but he knew that it was stuck in the hair of an Indian and he was looking for different game. He became so eager that he flattened his face against the rock and thrust forward the rifle barrel that he might lose no chance however fleeting.
Silent Tom's figure and face were so tense and eager that Henry stopped watching the bushes a moment or two to look at him. But Tom continued to search for his target. He missed nothing that human eye could see among those bushes, trees and rocks. He saw an eagle feather again, but it did not interest him. Then he heard the baying of a hound, and he quivered from head to foot,
