"And will he take me there?"

"Yes; the Beaver will take his brother there, and give it all into his hands."

"At last!" cried the Doctor excitedly. Then in a low voice, "Suppose it should not prove to be silver after all?"

"I know it is silver," said the Indian, quietly. "Look," he cried, taking a clumsily-made ring from his medicine-bag. "That came from there, so did the ring upon the lariat of the chief."

"Ask him when he will take me there!" cried the Doctor.

"He says now," replied the Indian, smiling at the Doctor's eagerness and excitement. "It is a long way, and the plains are hot, and there is little water; but we can hunt as we go, and all will be well."

"You know the way from here down into the plain?" said the Doctor. "It is a long way, is it not?"

The Indian smiled. "It is a very short journey," he said. "I know the way."

In effect they started as soon as the camp was struck, and the Beaver, leading the way, took them down a deep gulch, of whose existence they were unaware, by which they made an easy descent into the plain, and into which they pa.s.sed with such good effect that at sunset the bold bluff where the adventure with the bears had taken place stood up in the distance, with the steep wall falling away on either side, looking diminutive in the distance, and very different to what it really was.

They had had a rapid progress over a long range of perfectly level plain, the horses, after the toils in the mountains, seeming quite excited at having gra.s.s beneath their feet; and hence it was that when they were camping for the night, and Bart's beautiful cob with long mane and tail had been divested of saddle and bridle, and after being watered was about to be secured by its lariat to the tether-peg, the excitable little creature, that had been till now all docility and tractableness, suddenly uttered a shrill neigh, pranced, reared up, and before Bart could seize it by the mane, went off across the plain like the wind.

The loss of such a beast would have been irreparable, and the Doctor and Joses ran to untether their horses to join pursuit, but before they could reach them, the Beaver and half a dozen of his men were after the cob at full speed, loosing their lariats as they rode and holding them over their heads ready to use as la.s.soes as soon as they could get within reach of the fugitive.

No easy task this, for as, dolefully enough, Bart looked on from the waggon, he could see his little horse keeping a long distance ahead, while now the Indians seemed to be making to the left to try and cut the restive little creature off, as he made for a wild-looking part of the plain about a couple of miles away.

Bart was helpless, for there was no horse of their own left that was of the slightest use for pursuit of his swift little cob, and all he could do was to stare after those engaged in the pursuit in a hopeless way as the truant galloped on at full speed, swishing its tail, tossing its head, and apparently revelling in its newly-found liberty.

All at once Bart became aware of the fact that one of the Indians had been for some minutes watching him attentively, and the man had uttered a low guttural laugh as if he were enjoying the youth's misfortune.

"I wonder how he would like it," thought Bart, as he darted an indignant look at the Indian, who sat upon his swift pony like a group cut in bronze. "He might just as well have gone after Black Boy, for his pony looks as if it could go."

Just then the Indian threw himself lightly from his nag and drew near to Bart, with the horse-hair rein in his hand. Then he made signs to the young fellow to mount.

"Do you mean that you will lend me the pony to go after my own?" said Bart eagerly.

The Indian did not understand his words, but evidently realised their meaning, for he smiled and nodded, and placed the rein in Bart's hand, when he leaped into the saddle, or rather into the apology for a saddle, for it was only a piece of bison hide held on by a bandage, while a sort of k.n.o.b or peg was in the place of the pommel, a contrivance invented by the Indians to hold on by when attacking a dangerous enemy, so as to lie as it were alongside of their horse, and fire or shoot arrows beneath its neck, their bodies being in this way thoroughly protected by their horses.

The Indian smiled and drew back when Bart touched the pony with his heel, the result being that, instead of going off at a gallop, the little restive beast reared up, pawing at the air with its hoofs, and nearly falling backwards upon its rider.

The Indian looked on intently as if ready to leap forward and seize the bridle should Bart be dismounted. But the lad kept his seat, and the pony went on all fours again, but only to begin kicking furiously, to dislodge the strange white-faced being upon its back. It was like an insult to an animal that had been accustomed to carry true-blooded Indians all its life, dressed in skins ornamented with feathers and neatly painted up for special occasions, to have a pale-faced, undersized human animal in strange clothes mounted upon it; and the proper thing seemed to be to kick him off as soon as it could.

These seemed to be the ideas of the Indian pony as exemplified by its acts; but the wildest of animals of the horse family cannot always do as they please, and it was evidently with something like astonishment that the little steed found Bart, still fixed firmly upon its back instead of flying over its head or slipping off backwards over the tail.

This being so, the pony began to what is called "buck," that is to say, instead of letting its back remain in an agreeable hollow curve, one which seems to have been made by nature on purpose to hold a human being, it curved its spine in the opposite direction, arching it as a cat would, but of course in a modified way, and then began leaping up from the earth in a series of buck jumps, all four hoofs from the ground at once.

Still, in spite of this being the most difficult form of horse trouble to master, Bart kept his seat. He was jerked about a great deal, but he had been long used to riding restive horses, and he sat there as coolly as if in a chair.

Then the Indian pony uttered a few shrill snorts and squeaks, throwing up its head, and finally turning round, first on one side then upon the other, it tried to bite its rider's legs--attacks which Bart met by a series of sharp blows, given with the lariat that was coiled by the horse's neck.

These pranks went on for a few minutes, the Indian looking smilingly on the while, till, seeing that Bart was not to be dislodged, the pony began to back and finally lay down.

This of course dismounted the rider, and with a snort of triumph the pony sprang to its feet again, evidently meaning to bound off after Black Boy and enjoy a turn of freedom.

The pony had reckoned without its rider, for Bart was too old at such matters to leave his grasp of the rein, and the Indian cob's first knowledge of its mistake was given by a sharp check to its under jaw, round which the horse-hair rope was twitched, the next by finding its rider back in his old place where he had leaped as lightly as could be.

The Indian gave an approving grunt, and uttering what was quite a sigh, the pony resigned itself to its fate, and obeying the touch of Bart's heel, went off at a fine springing gallop.

It was a long chase and an arduous one, for Black Boy seemed to laugh to scorn all attempts at capture--of course these were horse-laughs--and led his pursuers a tremendous run; and had it not been for his master, late as he was in the field, the cob would not have been captured that night. As it was, Bart went off at speed, setting at defiance prairie-dogs' burrows, and other holes that might be in his way, and at last he contrived to cut off a corner so as to get nearer to his nag, when, taking the rein beneath his leg, he placed both hands to his mouth and uttered a long shrill cry.

It acted like magic upon Black Boy, who recognised it directly as his master's call, and having had his frolic, he trotted slowly towards where Bart cantered on, suffered himself to be caught, and the party returned in triumph, none the worse, save the tiring, for the adventure.

CHAPTER FOURTEEN.

THE SILVER CANYON.

A week's arduous journey over a sterile stretch of country, where water was very scarce and where game was hard to approach, brought them at last in reach of what looked to be a curiously formed mountain far away in the middle of an apparently boundless plain. Then it struck Bart that it could not be a mountain, for its sides were perpendicular, and its top at a distance seemed to be perfectly flat, and long discussions arose between him and the Doctor as to the peculiarity of the strange eminence standing up so prominently right in the middle of the plain.

While they were discussing the subject, the Beaver and his English-speaking follower came to their side, and pointing to the mountain, gave them to understand that this was their destination.

"But is there silver there?" said the Doctor eagerly, when the Indian smiled and said quietly, "Wait and see."

The mountain on being first seen appeared to be at quite a short distance, but at the end of their first day's journey they seemed to have got no nearer, while after another day, though it had a.s.sumed more prominent proportions, they were still at some distance, and it was not until the third morning that the little party stood on the reedy sh.o.r.es of a long narrow winding lake, one end of which they had to skirt before they could ride up to the foot of the flat-topped mountain which looked as if it had been suddenly thrust by some wondrous volcanic action right from the plain to form what appeared to be a huge castle, some seven or eight hundred feet high, and with no ravine or rift in the wall by which it could be approached.

All Bart's questions were met by the one sole answer from the Indian, "Wait and see;" and in this spirit the savages guided them along beneath the towering ramparts of the mountain, whose scarped sides even a mountain sheep could not have climbed, till towards evening rein was drawn close under the mighty rocks, fragments of which had fallen here and there, loosened by time or cut loose by the shafts of storms to lie crumbling about its feet.

There seemed to be no reason for halting there, save that there was a little spring of water trickling down from the rocks, while a short distance in front what seemed to be a wide crack appeared in the plain, zigzagging here and there, one end going off into the distance, the other appearing to pa.s.s round close by the mountain; and as soon as they were dismounted and the horses tethered, the Beaver signed to Bart and the Doctor to accompany him, while the interpreter followed close behind.

It was a glorious evening, and after the heat of the day, the soft, cool breeze that swept over the plain was refreshing in the extreme; but all the same Bart felt very hungry, and his thoughts were more upon some carefully picked sage grouse that Joses and Maude were roasting than upon the search for silver; but the Doctor was excited, for he felt that most likely this would prove to be the goal of their long journey. His great fear was that the Indians in their ignorance might have taken some white shining stone or mica for the precious metal.

The crack in the plain seemed to grow wider as they approached, but the Indians suddenly led them off to the right, close under the towering flank of the mountain, and between it and a ma.s.s of rock that might have been split from it at some early stage in the world's life.

This ma.s.s was some forty or fifty feet high, and between it and the parent mountain there was a narrow rift, so narrow in fact that they had to proceed in single file for about a hundred yards, winding in and out till, reaching the end, the Indians stood upon a broad kind of shelf of rock in silence as the Doctor and Bart involuntarily uttered a cry of surprise.

For there was the crack in the plain below their feet, and they were standing upon its very verge where it came in close to the mountain, whose top was some seven hundred feet above their heads, while here its perpendicular side went down for fully another thousand to where, in the solemn dark depths of the vast canyon or crack in the rocky crust of the earth, a great rushing river ran, its roar rising to where they stood in a strangely weird monotone, like low echoing thunder.

The reflections in the evening sky lighted up the vast rift for a while, and Bart forgot his hunger in the contemplation of this strange freak of nature, of a river running below in a channel whose walls were perfectly perpendicular and against which in places the rapid stream seemed to beat and eddy and swirl, while in other parts there were long stretches of pebbly and rocky sh.o.r.e. For as far as Bart could judge, the walls seemed to be about four hundred feet apart, though in the fading evening light it was hard to tell anything for certain.

A more stupendous work of nature had never met Bart's eye, and his first thoughts were natural enough--How should he manage to get to the top of that flat mountain?--How should he be able to lower himself down into the mysterious shades of that vast canyon, and wander amongst the wonders that must for certain be hidden there?

Just then the Beaver spoke. He had evidently been taking lessons from the interpreter, as, smiling loftily and half in pity at the eagerness of men who could care for such a trifle as white ore when they had horses and rifles, he pointed up at the perpendicular face of the mountain and then downward at the wall of the canyon, and said:--

"Silver--silver. Beaver give his brother. Medicine-man."

"He means there is silver here, sir, and he gives it to you," said Bart eagerly.

"Yes. Give. Silver," said the chief, nodding his head, and holding out his hand, which the Doctor grasped, Bart doing the same by the other.

"I am very grateful," said the Doctor at last, while his eyes kept wandering about, "but I see none."
