The five went on in silence, so far as they were concerned, for a long time, but the baying behind them never ceased. It also grew louder, and Henry, glancing hastily back, expected that the dogs would soon come into sight.

"Judging from their barking, the Wyandots must love dogs of uncommon size and fierceness," he said.

"'Pears likely to me," said Shif'less Sol. "We're good runners, all five o' us. We've shaken the warriors off, but not the dogs."

"It's just as you say," said Henry. "We can't run on forever, so we must shoot the trailers--that is--the dogs. Listen to them. They are not more than a couple of hundred yards away now."

They crossed a little open s.p.a.ce, leaped a brook and then entered the woods again. But at a signal from Henry, they stopped a few yards further on.

"Now, boys," he said, "be ready with your rifles. We must stop these dogs. How many do you think they are, Tom?"

"'Bout four, I reckon."

"Then the moment they come into the open s.p.a.ce, Tom, you and Paul and Jim shoot at those on the left, and Sol and I will take the right."

The Indian dogs sprang into the open s.p.a.ce and five rifles cracked together. Three of them--they were four in number, as Tom had said--were killed instantly, but the fourth sprang aside into the bushes, where he remained. The five at once reloaded their rifles as they ran. Now they increased their speed, hoping to shake off their pursuers. Behind them rose a long, fierce howl, like a note of grief and revenge.

"That's the dog we did not kill," said Paul, "and he's going to hang on."

"I've heard tell," said Tom Ross, "that 'cordin' to the Indian belief, the souls o' dead warriors sometimes get into dogs an' other animals, an' it ain't fur me to say that it ain't true. Mebbe it's really a dead Injun, 'stead o' a live dog that's leadin' the warriors on."

Paul shuddered. Tom's weird theory chimed in with his own feelings. The fourth dog, the one that had hid from the bullets, was a phantom, leading the savages on to vengeance for his dead comrades. Now and then he still bayed as he kept the trail, but the fleeing five sought in vain to make him a target for their bullets. Seemingly, he had profited by the death of his comrades, as his body never showed once among the foliage. Search as they would with the sharpest of eyes, none of the five could catch the faintest glimpse of him.

"He's a ghost, sh.o.r.e," said Tom Ross. "No real, ordinary dog would keep under cover that way. I reckon we couldn't kill him if we hit him, 'less we had a silver bullet."

The savages themselves uttered the war cry only two or three times, but it was enough to show that with the aid of the dog they followed relentlessly. The situation of the five had become alarming to the last degree. They had intended to pursue, not to be pursued. Now they were fleeing for their lives, and there would be no escape, unless they could shake off the most terrible of all that followed--the dog. And at least one of their number, Silent Tom Ross, was convinced thoroughly that the dog could not be killed, unless they had the un.o.btainable--a silver bullet. In moments of danger, superst.i.tion can take a strong hold, and Paul too, felt a cold chill at his heart.

Their course now took them through a rolling country, clad heavily in forest, but without much undergrowth, and they made good speed. They came to numerous brooks, and sometimes they waded in them a little distance, but they did not have much confidence in this familiar device.

It might shake off the warriors for a while, but not that terrible dog which, directed by the Indians, would run along the bank and pick up the trail again in a few seconds. Yet hope rose once. For a long time they heard neither bark nor war cry, and they paused under the branches of a great oak. They were not really tired, as they had run at an easy gait, but they were too wise to let pa.s.s a chance for rest. Henry was hopeful that in some manner they had shaken off the dog, but there was no such belief in the heart of the silent one. Tom Ross had taken out his hunting knife and with his back to the others was cutting at something.

Henry gave him a quick glance, but he did not deem it wise to ask him anything. The next moment, all thought of Tom was put out of his mind by the deep baying of the dog coming down through the forest.

The single sound, rising and swelling after the long silence was uncanny and terrifying. The face of Tom Ross turned absolutely pale through the tan of many years. Henry himself could not repress a shudder.

"We must run for it again," he said. "We could stay and fight, of course, but it's likely that the Indians are in large numbers."

"If we could only shake off the hound," muttered Tom Ross. "Did you pay 'tention to his voice then, Henry? Did you notice how deep it was? I tell you that ain't no common dog."

Henry nodded and they swung once more into flight. But he and Shif'less Sol, the best two marksmen on the border, dropped to the rear.

"We must get a shot at that dog," whispered Henry. "Very likely it's a big wolf hound."

"I think so," said Shif'less Sol, "but I tell you, Henry, I don't like to hear it bayin'. It sounds to me jest ez ef it wuz sayin': 'I've got you! I've got you! I've got you!' Do you reckon there kin be anything in what Tom says?"

"Of course not. Of course not," replied Henry. "Tom's been picking up too much Indian superst.i.tion."

At that moment the deep baying note so unlike the ordinary bark of an Indian dog came again, and Henry, despite himself, felt the cold chill at his heart once more. Involuntarily he and the shiftless one glanced at each other, and each read the same in the other's eyes.

"We're bound to get that dog, hound, cur, or whatever he may be!"

exclaimed Henry almost angrily.

Shif'less Sol said nothing, but he cast many backward glances at the bushes. Often he saw them move slightly in a direction contrary to the course of the wind, but he could not catch a glimpse of the body that caused them to move. Nor could Henry. Twice more they heard the war cry of the savages, coming apparently from at least a score of throats, and not more than three or four hundred yards away. Henry knew that they were depending entirely upon the dog, and his eagerness for a shot increased. He could not keep his finger away from the trigger. He longed for a shot.

"We must kill that dog," he said to Shif'less Sol; "we can't run on forever."

"No, we can't, but we kin run jest as long as the Injuns kin," returned the shiftless one, "an' while we're runnin' we may get the chance we want at the dog."

The pursuit went on for a long time. The Indians never came into view, but the occasional baying of the hound told the fleeing five that they were still there. It was not an unbroken flight. They stopped now and then for rest, but, when the voice of the hound came near again, they would resume their easy run toward the South. At every stop Tom Ross would turn his back to the others, take out his hunting knife and begin to whittle at something. But when they started again the hunting knife was back in its sheath once more, and Tom's appearance was as usual.

The sun pa.s.sed 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 pa.s.sed, 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. .h.i.t on my nerves, they do."

The chance of the shiftless one came presently. He, too, saw among the bushes the long dark body, the ma.s.sive 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.
