"They may begin again," said Boyd, "but by then we ought to be far away."

It was a venture largely at random, but the three were agreed that it must be made. The Sioux undoubtedly would resume the bombardment later on, and they might also receive reinforcements sufficient to resume the attack at the mouth of the pa.s.s, or at least to keep up there a distant fire that would prove troublesome. Every motive prompted to farther flight, and they pushed on as fast as they could, although the bottom of the defile became rough, sown with bowlders and dangerous to the fugitives.

They made no attempt to ride, but led the horses and mules at the ends of their lariats, all the animals becoming exceedingly wary at the bad footing.

"It's a blind canyon after all!" suddenly exclaimed the Little Giant in deep disgust. "The stream comes down that mountain wall thar, droppin'

from ledge to ledge, an' here we are headed off."

"Then there's nothing to do," said the hunter, "but choose a good place among the rocks and fight for our lives when they come."

Will looked up at the steep and lofty slopes on either side. The one on the right seemed less steep and lofty than the other, and upon it hung a short growth of pine and cedar, characteristic of the region. His spirit, which danger had made bold and venturesome, seized upon an idea.

"Why not go up the slope on the right?" he asked.

"It's like the side of a house, only many times as high," said Boyd in amazement.

"But it isn't," said the lad. "It merely looks so in the dark. We can climb it."

"Of course we could, but we'd have to abandon the horses and mules and all our packs and stores, and then where would we be?"

"But we won't have to leave 'em. They can climb too. You know how you boasted of our horses, and the Giant's horses are mules which can go anywhere."

"I believe the boy's right," said the Little Giant. "By our pullin' on the lariats an' thar takin' advantage o' ev'ry footgrip, they might do it. Leastways we kin try it."

"It's a desperate chance," said the hunter, "but I think with you, Tom, that it's worth trying. Now, boys, make fast the packs to the last strap, and up we go."

"Bein' as my hosses are mules," said the Little Giant, "I'll lead the way, an' you foller, each feller pullin' on two lariats."

He started up the slope, whistling gayly but low to his mules, and, after some hesitation, they attacked the ascent, Tom still whistling to them in his most cheerful and engaging manner. There was a sound of scrambling feet, and small stones rolled down, but not the mules, which disappeared from sight among the cedars.

"Thunderation! I wouldn't have thought it!" exclaimed the hunter, "but I believe you're right, Will! The mules are climbing the wall. Now, we'll see if the horses can do it!"

"Let me start with 'em!"

"All right! But pull hard on the lariat, whenever you feel one of 'em slipping."

Will attacked the steep wall with vigor, but he had to pull very hard indeed on the lariats before he could make the horses try it. Finally they made the effort, and, though slipping and sliding at times, they crept up the slope. Behind him he heard Boyd, coming with the last two and speaking in encouraging tones to Selim.

The lariats were a great help, and if Will had not hung on to them so hard his horses would have fallen. But he was right in his judgment that the face of the wall was not so steep as it looked. Moreover there were little shelves and gullies, and the tough clumps of cedar were a wonderful aid. The horses justified their reputation as climbers, and, although Will's heart was in his mouth more than once, and his hands and wrists were cut and bleeding by the pull on the lariats, they did not fall. Always he heard in front of him the low and cheerful whistling of the Little Giant, to his mules, which, sure-footed, went on almost without a slip.

At last they drew out upon the crest of the slope and the three human beings and the six animals stood there trembling violently from exertion, the perspiration pouring from them.

"My legs are shaking under me," said the hunter. "I'd never have believed that it could have been done, and I know it couldn't, but here we are, anyhow."

"It wuz young William who thought of it, and who dared to speak of it,"

said the Little Giant, "an' so it's his win."

"Right you are, Giant," said the hunter heartily. "When I looked at that cliff it stood up straight as a wall to me. It was like most other things, it wasn't as hard when you attacked it as you thought it was, but I still don't see how we ever got the animals up, and if I didn't see 'em standing here I wouldn't believe it."

Will, holding to a cedar, looked into the gulf from which they had climbed. As more of the stars had gone away he could not now see the bottom. The great defile had all the aspects of a vast and bottomless abyss, and he felt that their emergence from it was a marvel, a miracle in which they had been a.s.sisted by some greater power. He was a.s.sailed by a weakness and, trembling, he drew back from the ledge. But neither the hunter nor the Little Giant had seen his momentary collapse and he was glad, pardonable though it was.

"The ground back o' the cliff seems to be pretty well covered with forest," said the Little Giant, "an' I reckon we'd better stay here a spell 'til everybody, men an' animals, git rested up a bit."

"You never spoke truer words, Tom Bent," said Boyd. "I can make out a fairly level stretch of ground just ahead, and I'll lead the way to it."

They crouched there. "Crouch" is the only word that describes it, as the horses and mules themselves sank down through weariness, and their masters, too, were glad enough to lie on the earth and wait for their strength to come back. Will's senses, despite his exhaustion, were nevertheless acute. He heard a heavy, lumbering form shuffling through a thicket, and he knew that it was an alarmed bear moving from the vicinity of the intruders. He heard also the light tread of small animals.

"I judge from these sounds," said Boyd, "that we must be on a sort of plateau of some extent. If it was just a knife edge ridge between two chasms you wouldn't find so many animals here. Maybe we'd better lay by until day, or until it's light enough to see. In the dark we might tumble into some place a thousand feet deep."

"What about the Sioux who were on the heights throwing down the rocks?"

asked Will. "Mightn't they come along the cliff and find us here?"

"No. The way may be so cut by dips and ravines that it's all but impa.s.sable. The chances are a thousand to one in favor of it, as this is one of the roughest countries in the world."

"A thousand to one is good enough for me," said Will, stretching himself luxuriously on the ground. Presently he saw Boyd and Bent wrapping themselves in the blankets and he promptly imitated them, as a cold wind was beginning to blow down from the northwest, a wind that cut, and, at such a time, a lack of protection from the weather might be fatal.

The warmth from the blankets pervaded his frame, and with the heat came the restoration of his nerves. There was also a buoyancy caused by the escape from the Sioux, and, for the time being at least, he felt a certain freedom from care. His comrades and the animals did not stir, and, while not thinking of sleep, he fell asleep just the same.

He was awakened by a long, fierce shout, much like the howl of hungry wolves, and full of rage and disappointment. He sat up on his blankets, and was amazed to hear the two men laughing softly.

"It's them thar Sioux, Will," said the Little Giant. "They've found out at last that thar was no outlet at the end o' the pa.s.s, an' they've come up it to the end, jest to run ag'inst a blank wall, an' to find that we've plum' vanished, flew away, hosses an' mules an' all."

"But won't they find our trail up the cliff?"

"No, they won't dream o' sech a thing, but in case they do dream o' it we'll all three creep to the edge an' set thar with our repeatin'

rifles. A fine time they'd hev climbin' up thar in the face o' three sharpshooters armed with sech weapons ez ours."

Will saw at once that their position was well nigh impregnable, at least against foes in the defile, and he crept with the others to the edge, not forgetting his invaluable gla.s.ses. A lot of the stars had come back and with the aid of the powerful lenses, he was able to penetrate the depths of the pa.s.s, seeing there at least a score of Sioux in a group, apparently taking counsel with one another. He could not discern their faces, and, of course, their words were inaudible at the distance, but their gestures expressed perplexity. Their savage minds might well believe that witchcraft had been at work, and he hoped that they had some such idea. The climbing of the cliff by the animals was an achievement bordering so closely upon the impossible that even if they saw traces of the hoofs on the lower slopes they would think the spirits of the air had come down to help the fugitives.

"What are they doing, young William?" asked the Little Giant.

"Nothing that I can see except to talk as if puzzled."

"I almost wish they would strike our trail and start up the cliff. We could pick off every one of 'em before they reached the top."

"I'd rather they went back."

"That's what they're likely to do, young William. Even if they saw our trail going up the cliff, they won't follow it. They've had a taste of our marksmanship, an' they know it would be certain death. It looks to me ez if they wuz goin' to drift back down the trail."

"You judge right, Tom. There they go. I wish I could read the expression on their faces. They must be wild with rage. They're moving a little faster now, and the sooner they disappear from my sight the better."

He handed the gla.s.ses to the Little Giant, who, after taking a look, pa.s.sed them to Boyd. The hunter had the last glimpse of them as they turned a curve and were hidden by the rocky wall.

"That settles 'em, for the time, anyway," he said, "and now I think we'd better see what kind of a country we've come into. You stay here with the animals, Will, they like you and it's easy for you to keep 'em quiet, while Giant and me scout about and see the lay of the land."

Will promptly accepted his part of the task. The horses and mules, alarmed perhaps by such a wild and lonely situation, and tremulous, too, from memories of that frightful climb up the cliff, crowded close about him, while he stroked their noses and manes, and felt himself their protector.

The hunter and the Little Giant vanished without noise, and Will waited a full hour before either returned. But he was not lonesome. The horses and mules rubbed their noses against him, and in the dark and the wilderness they made evident their feeling that he was the one who would guard them.
