The whole difficulty was then made clear to the lad. If the Apaches were nowhere but in the rear, it would be an easy matter to give them the slip, but they were on the right and left, and in front, and signs that had been seen through the day indicated very clearly that the Indians were carrying out to the letter the plan of which the hunters had spoken, and which they dreaded so much. They had already surrounded them, the circle being quite a number of miles in diameter, and were now simply drawing in their lines. This, as a matter of course, made a collision inevitable, unless the hunters could manage to steal between these redskins, and, by striking the open country beyond, place the entire company in their rear. Such a plan as this was scarcely possible of accomplishment. If attempted during the daytime, it would be instantly detected by some of the redskins, who would notify the proper ones, when an immediate concentration would take place in front of the fugitives. If tried during the darkness of night, it would fail. The Apaches would take every imaginable precaution against it and there was no means of concealing the noise made by hoofs. By going on foot they could get through the lines without difficulty; but they could not commit the imprudence of leaving their horses. The situation, therefore, was critical. Tom made known two most important facts. The first was that beyond a doubt Lone Wolf was at the head of the whole enterprise, and they were likely to meet with this treacherous chief again. The second was that, in case they were driven to the wall, the hunters had determined upon taking refuge in a place known as Hurricane Hill. "It's nothing more than a pile of rocks," added Hardynge. "I've been there before, and it's just the spot to make a desp'rit stand. Two men like us, if we can reach the right p'int, can keep a hundred of the redskins back." "Won't they get there ahead of us?" asked Ned. "I think not," replied the hunter, in that hesitating manner which showed that he had thought of the contingency before; "for the reason that I b'leve they'd like to have us run there; but, come, let's be off." That the mustangs might be relieved, the lad was now taken on the back of Dick's, and the journey toward the southwest was resumed at the same sweeping gallop. Tom took the lead, carefully scanning the ground over which they traveled. For an hour all went well, and then he reined up his steed with startling suddenness. "Look yonder!" he said, pointing to the south. Glancing in the direction indicated, the boy saw a number of moving specks, apparently on the very horizon. "Injuns," said Dick, in a low voice, although the boy scarcely needed the explanation to know they were their old enemies--mounted Apaches. "Do you see 'em?" "Yes." "Now take a peep off there." This time the hunter pointed exactly opposite, where almost precisely the same thing was visible.
