Bart promised, and went at once to the Beaver and Joses.

“I’m to come too, ain’t I?” said the latter.

“No, you are to help keep guard,” was the reply; and very sulkily Joses resumed his place, while the Beaver descended with Bart and four of his men to enter the rock stable and obtain their horses, the rest having to remain fasting while their companions were mounted and ridden out; the Indian ponies in particular resenting the indignity of being shut up again behind the stones by turning round and kicking vehemently.

The Apachés were so far distant that Bart was in hopes that they would not see the reconnaissance that was being made, as he rode out at the head of his little Indian party, after fully explaining to the Beaver that which they were to do.

His first step was to inspect the part of the mountain on the side that was nearest to the chimney, and the chasm into which they had descended to see the silver on their first coming.

This was the shortest portion by far, and it had the advantage of a good deal of cover in the shape of detached rocks, which sheltered them from the eyes of those upon the plain; but all the same, the Beaver posted two of his men as scouts in good places for observing the movements of the foe and giving warning should they approach; the plan being to take refuge beneath the gallery, where they would be covered by the rifles of Joses and their friends.

It was not at all a difficult task to satisfy the most exacting that ascent from the plain anywhere from the gallery to the precipice at the edge of the canyon was utterly impossible; and after carefully examining every crack and rift that ran upwards, the little party cantered back, said a few words to Joses, and then prepared for their more risky task, that of examining the mountain round by its northern and more open side, for there was no cover here, and their path would be more fully in view of any watchful eye upon the plain.

They drew up by the gateway, and had a few minutes’ conversation with the Doctor, who said at parting:

“You can soon satisfy yourself, Bart; but give a good look up as you come back, in case you may have missed anything in going.”

“I’ll be careful,” said Bart eagerly.
