"Nay, we have not, my lad; we've gained time, and your eyes have had such a eddication this morning as can't be beat."

"Well, let's get back now. I suppose we may get up and walk."

"Walk! what, do you want to have the Injuns back on us?"

"They could not see us here."

"Not see us! Do you suppose they're not sharper than that. Nay, my lad, when the Injuns come down upon us let's have it by accident. Don't let's bring 'em down upon us because we have been foolish."

Bart could not help thinking that there was an excess of care upon his companion's side, and said so.

"When you know the Injuns as well as I do, my lad, you won't think it possible to be too particular. But look here--you can see the Injuns out there, can't you?"

"Yes, but they look like ants or flies."

"I don't care what they look like. I only say you can see them, can't you?"

"Yes."

"And you know Injuns' eyes and ears are sharper than ours?"

"Not than yours."

"Well, I know that they are sharper than yours, Master Bart," said Joses, with a chuckle; "and now look here--if you can see them out there against the dry brown plain miles away, don't you think they could see us stuck up against the sky here in the bright morning sunshine, all this height above the ground?"

"Well, perhaps they could, if they were looking," said Bart rather sulkily.

"And they are looking this way. They always are looking this way and every way, so don't you think they are not. Now let's go down."

He set the example of how they should go down, by crawling back for some distance till he was below the ridge and beyond sight from the plain, Bart carefully following his example till he rose, when they started down the hill at as quick a trot as the rugged nature of the ground would permit, and soon after reached the waggon, which the Doctor had drawn into a position which hid it from the view of any one coming up from the entrance of the valley, and also placed it where, in time of peril, they might hold their own by means of their rifles, and keep an enemy at bay even if they did not beat him off.

CHAPTER FIVE.

"SURROUNDED BY INDIANS."

A good breakfast and a few hours' rest seemed to put a different aspect upon the face of affairs; the day was glorious, and though the region they were in was arid and wanting in water, there was plenty to interest any one travelling on an expedition of research. A good look-out was kept for Indians, but the party seemed to have gone right away, and to give them ample time to get to a greater distance, Dr Lascelles determined, if he could find a spring anywhere at hand, to stay where they were for a couple of days.

"You see, Bart," he said, as they hunted about amongst the craggiest part of the amphitheatre where fortune or misfortune had led them, "it does not much matter where we go, so long as it is into a region where Europeans have not penetrated before. Many of these hills are teeming with mineral treasures, and we must come upon some of Nature's wasting store if we persevere."

"Then we might find metals here, sir?" said Bart eagerly.

"As likely here as anywhere else. These rocks are partly quartz, and at any time we may come upon some of the stone veined with gold, or stumble upon a place where silver lies in blocks."

"I hope," laughed Bart, "when we do, I may stumble right over one of the blocks and so be sure of examining it. I think I should know silver if I found it."

"I am not so sure," said the Doctor. "You've led a life of a kind that has not made you very likely to understand minerals, but I daresay we shall both know a little more about them before we have done--that is,"

he added with a sigh, "if the Indians will leave us alone."

"We must give them the slip, sir," said Bart, laughing.

"Perhaps we may, my boy; but we have another difficulty to contend with."

"What's that, sir; the distance?"

"No, Bart; I'm uneasy about the men. I'm afraid they will strike sooner or later, and insist upon going back."

"I'm not, sir," replied Bart. "I will answer for Joses, and he has only to say he means to go forward, and the others then will keep by his side. Mind that snake, sir."

The Doctor raised his rifle to fire, but refrained, lest the report should be heard, and drawing back, the rattlesnake did the same; then they continued their journey, the Doctor examining the rocks attentively as he went on, but seeing nothing worthy of notice.

"We must be well on our guard against these reptiles, Bart; that is the first I have seen, and they may prove numerous."

"They are numerous," said Bart; and he told of the number he had seen upon the slope above them.

"That settles me upon going forward this evening," said the Doctor, "for water seems to be very scarce. We must try and strike the river higher up, and follow its course. We shall then have plenty of water always within reach, and find wood and trees and hiding-places."

"But I thought you wanted to get into a mountainous part, sir, where precious minerals would be found," said Bart.

"Exactly, my dear boy, and that is just the place we shall reach if we persevere, for it is up in these rocky fastnesses, where the rivers have their sources, and sometimes their beds are sprinkled with the specks and also with pieces of gold that have been washed out of the sides of the mighty hills."

They went on thoughtfully for a time, the Doctor giving a chip here and a chip there as he pa.s.sed ma.s.ses of rock, but nothing rewarded him, and their walk was so uneventful that they saw nothing more than another rattlesnake, the valley being so solitary and deserted that, with the exception of a large hawk, they did not even see a bird.

They, however, found a tiny spring of water which trickled down among the rocks, and finally formed a little pool, ample for supplying their horses with water, and this discovery made the Doctor propose a return.

"I don't like leaving Maude for long," he said.

"Joses will watch over her, sir, as safely as you would yourself. You saved his life once he told me."

"He told you that!" exclaimed the Doctor.

"Yes, sir, when the rattlesnake bit him, and I don't think he would ever be ungrateful, though I think he feels hurt that you do not place more trust in him."

"Well, let him prove himself well worthy of my trust," said the Doctor, bluntly. "I have not found him so ready as he should be in helping me with my plans."

Here the Doctor became very silent and reserved, and though Bart asked him several questions, and tried to get him into conversation, he hardly spoke, but seemed moody and thoughtful till they were close upon the little camp.

This was hidden from them till they were almost there, for the upper end of the Horse-shoe Valley was extremely rugged, and their way lay in and out among heavy blocks of stone that seemed as if they had been hurled down from the mountain-side.

When they were just about to turn into the narrow opening where the waggon lay and the horses were tethered, the Doctor stooped down to examine some fragments that lay loose about their feet, and the consequence was that Bart went on alone. He was just about to give a peculiar whistle, one used commonly by himself and the men when they wished to signal their whereabouts, when he stopped short, half hidden by the rocks, raised his rifle to his shoulder, and stood ready to fire, while his face, tanned as it was by the sun, turned of a sickly hue.

For a moment he was about to fire. Then he felt that he must rush forward and save Maude. The next moment calmer reflection told him that such help and strength as he could command would be needed, and, slipping back out of sight, he ran to where he had left the Doctor.

He found him sitting down examining by means of a little magnifying-gla.s.s one of the fragments of rock that he had chipped off, while his rifle lay across his knee.

He seemed so calm and content that in those moments of emergency Bart almost shrank from speaking, knowing, as he did, how terrible would be the effect of his words.

Just then the Doctor looked up, saw his strange gaze, and dropping the fragments, he leaped to his feet.
