Realizing that they were getting nowhere by these ineffective tactics Jack again sought suggestions from his second in command. When Red vigorously advised that they try to find the secret rear entrance to the cavern, it struck Jack as a sensible plan. Knowing that there was little risk of the inmates making any serious attempt to rush out at this early stage of the battle, especially when unaware of the number of their foes, Jack concluded to accept the risks and take his whole inadequate force with him in making an attack from the rear.

It was indeed a lucky thing they had such a good guide at their disposal as Red proved to be; for he had no particular trouble in leading them along a narrow ledge, and through a branch of the main canyon, until they presently reached a dark crevice in the shape of a rock fault, exactly as his informant had advised would be the case.

This being the case they entered the split in the wall, and aided by occasional flashes from the hand electric torch Jack carried, managed in the end to reach the main cavern. Here torches fastened to the walls in the regulation fashion, allowed them to see the flitting figures of the alarmed bandits moving to and fro, as though engaged in changing their stores to some more secure location.

It appearing that only by a sudden rush could they hope to strike consternation into the hearts of the already panicky bunch, Jack gave the word, and with loud shouts and much firing of guns the three boldly rushed the enemy. In return came a volley of answering shots; but apparently this unexpected attack from the rear unnerved the outlaws, for breaking they rushed into an inner chamber, which had evidently been prepared for a last stand in case of just such an emergency as had now arrived. When the three came on the spot it was to find only a single form stretched on the rocky floor, and with a stout oaken door checking their further advance.

BACK OVER THE BORDER—CONCLUSION

Taking stock of the situation Jack found that things did not look so satisfactory as he could have wished. The outlaws, with but two missing from their number, so far as Jack could tell, had now retreated back of what seemed in the nature of a fort, which might defy all the efforts of himself and two companions to break in.

The thing that worried Jack most of all was the fact that Perk had been wounded in the last exchange of fierce firing. Just how serious this might prove he could not say; but his chum’s left arm seemed to hang helplessly at his side; although otherwise the war veteran displayed his usual scorn of a little blood-letting on his part.

“Looks kinder like we might be up a tree, partner,” Perk hoarsely told him as they came together while dodging the hot firing. “Mebbe now you’d better gimme permission to heave a couple o’ them little tear gas marbles into that ere hole in the wall! See there’s a place right over that same heavy door they left open for ventilation like; I could make a little rush up and push the pills through it in three shakes o’ a lamb’s tail. Say the word, buddy, an’ let’s end all this guess work.”

Jack himself realized it would be their best policy; he had before then witnessed the effective nature of those same small bombs under conditions not so very unlike those now confronting them; and remembered how mutinies in jails and penitentiaries down in the States were being effectually quelled by the use of similar methods.

“All right, Perk, have your way; the quicker it’s done the better, for I must have a look at that arm of yours, old man.”
