The four Sioux on the right, bent low, were urging their ponies forward at their utmost speed. From the band behind came a tremendous yell, which, despite the distance, reached Boyd and young Clarke, and, apparently, they had full warrant in thus giving utterance to their feeling of triumph. The sudden appearance of the warriors coming down the dip was like the closing of a trap and it seemed that all chance of escape was cut off from the two who rode so desperately for the mountains.
The hunter shut his teeth tightly and smiled in ironic fashion. Whenever he was highly pleased he grew rather talkative, and now he had much to say for a man whose life was about to turn on a hair.
"If the four on the ponies off there knew the peril into which they were riding they wouldn't ride so hard," he said. "But the Sioux are not yet acquainted with the full merits of a long range repeating rifle, nor do they understand how well I can shoot. I'm as good a marksman as there is in the West, if I do say it myself, and lest you may think me a boaster, Will, I'll soon prove it."
He dropped the reins on the neck of Selim, who, though unguided, ran on straight and true, and grasped the splendid rifle with both hands. Will ceased to think of the band behind them and began to watch the hunter, who, though still smiling, had become one of the most dangerous of human beings.
"Yes, my four friends, you're overhauling us fast," murmured the hunter, "and I'm glad of it, because then I don't have to do so much waiting, and, when there's ugly work at hand, one likes to get it over. Ah, I think they're near enough now!"
The rifle sprang to his shoulder, a jet of flame leaped from the muzzle, and, with the sharp crack, the foremost Sioux rolled to the ground and lay still, his frightened pony galloping off at an angle. The hunter quickly pulled the trigger again and the second Sioux also was smitten by sudden death. The other two turned, but one of them was wounded by the terrible marksman, and the pony of the fourth was slain, his rider hiding behind the body. A dismal wail came from the Sioux far back. The hunter lowered his great weapon, and one hand resumed the bridle rein.
"A rifle like mine is worth more than its weight in gold," he said. "It's worth its weight in diamonds, rubies, emeralds and all the other precious jewels at a time like this. I can say, too, that's about the best shooting I ever did, and I think it'll save us. Even the band behind, thirty or so in number, won't want to ride full tilt into rifles like ours."
"The first slopes are not more than three or four miles away now," said young Clarke, "and no matter how hard they push they can't overtake us before we reach the trees. But Jim, how are we to ride through those high mountains, and, if we abandon the horses, we might as well give up our quest."
"I chose these horses myself, Will," said Boyd, "and I knew what I was about. I trained Selim, and, of course, he's the best, but the others are real prize packages, too. Why, they can walk up the side of a cliff. They can climb trees, and they can jump chasms fifty feet wide."
"Come down to earth, Jim. Stay somewhere in the neighborhood of truth."
"Well, maybe I do draw a rather long bow, but horses learn to be mountain climbers, and ours are the very best of that kind. They'll take us up through the ridges, never fear. The Sioux will follow, for a while, at least, but in the deep forest you see up there we'll shake 'em off."
"Hear 'em shouting now! What are they up to?"
"Making a last rush to overtake us, while we're yet in the plain. But it is too late, my gay scalp hunters!"
The mountains were now drawing near very fast, and with the heavy forest along their slopes they seemed to Will to come forward of themselves to welcome them. He became suddenly aware that his body ached from the long gallop, and that the dust raised by the beating hoofs was caked thickly on his face. His lips were dry and burning, and he longed for water.
"In five more minutes we'll be on the first slope," said Boyd, "and as we'll soon be hidden in the forest I think I'll say farewell to our pursuers."
"I don't understand you, Jim."
"I'm going to say only one word, and it'll be short and sharp."
He turned suddenly in his saddle, raised the repeating rifle and fired once at the band.
He had elevated the sight for a very long shot, regarding it as a mere chance, but the bullet struck a pony and a few moments of confusion in the band followed. Now Boyd and young Clarke made their horses use the reserves of strength they had saved so prudently, and with a fine spurt soon gained the shelter of the woods, in which they disappeared from the sight of the pursuing horde.
They found themselves among oaks, aspens, pines, cedars, and birch, and they rode on a turf that was thick, soft and springy. But Selim neighed his approval and Boyd pulled down to a walk. A little farther on both dismounted at his suggestion.
"It'll limber us up and at the same time help the horses," he said. "Knowing what kind of rifles we carry and how we can shoot, the Sioux won't be in any hurry to ride into the forest directly after us. We've a big advantage now in being able to see without being seen. As we needn't hurry, suppose we stop and take another look with those glasses of yours, Will. I never thought they'd prove so useful when you insisted on bringing 'em."
Will obeyed at once.
"They're a mile or so away," he said, "and they've stopped. They're gathered in a semi-circle around one man who seems to be a chief, and I suppose he's talking to 'em."
"Likely! Most likely. I can read their minds. They're a little bit bashful about riding on our trail, when we have the cover of the forest. Repeating rifles don't encourage you to get acquainted with those who don't want to know you. I can tell you what they'll do."
"What, Jim?"
"The band will split into about two equal parts. One will ride to the right and the other to the left. Then, knowing that we can't meet both with the rifles, they'll cautiously enter the mountains and try to pick up our trail. Am I right or am I wrong?"
"Right, O, true prophet! They've divided and already they're riding off in opposite directions. And what's the best thing for us to do?"
"We'll lead the horses up this valley. I see through leaves a little mountain stream, and we'll drink there all the water we want. Then we'll push on deeper and deeper into the mountains, and when we think we're clear out of their reach we'll push on."
They drank plentifully at the brook, and even took the time to bathe their hands and faces. Then they mounted and rode up the slopes, the pack horses following.
"Didn't I tell you they were first class mountain climbers?" said Boyd with pride. "Why, mules themselves couldn't beat 'em at it."
When twilight came they were high on the slopes under the cover of the forest, pushing forward with unabated zeal.
CHAPTER III
THE LITTLE GIANT
Boyd rode in front, Will was just behind, and then came the two heavily laden pack horses, following their masters with a faith that nothing could shake. The hunter seemed to have an instinct for choosing the right way, or else his eyes, like those of an owl, were able to pierce the dark. He avoided chasms and cliffs, chose the best places on the slopes, and wherever he wound he always led deeper and deeper into the vast maze of high mountains.
Will looked back toward the plains, but he could see no trace of them now, and he did not believe that the Sioux, however skilled they might be, could follow their trail up the ridges in the dark. Meanwhile the stars came out, and a half moon rode in a medium sky. The boy's eyes, grown used to the night, were now able to see quite clearly, and he noticed that the region into which they were riding was steadily growing wilder. Now and then they passed so close to the edge of chasms that he shivered a little, as he looked down into the dark wells. Then they passed up ravines where the lofty cliffs, clothed in stunted pine and cedar, rose high above them, and far in the north he caught the occasional glimpses of white crests on which the snow lay deep.
Boyd became quite
