“Never say die,” replied Frank, who stood close at his cousin’s side, holding the lantern in one hand, and his revolver in the other. “We’ll not give up until we are bound hand and foot.”

All this while the Mexican had never once ceased his calls for assistance. He kept up a continuous roar, and presently answering shouts, and the tramping of numerous feet, told the fugitives that he had succeeded in attracting the attention of some of his companions. The reinforcements came on rapidly, and arrived in sight, and Archie had not yet been able to find a key that would open the door.

“Take it easy,” said Frank, who began to fear that his cousin’s nervousness and impatience would prove their ruin. He spoke calmly enough, but his face was very pale, and the lantern trembled in his grasp. This was the severest test that had been applied to his courage since he stood at that log awaiting the approach of the wounded and enraged grizzly; and yet he could speak in his ordinary tone of voice, without the least impatience, and advise his terrified and excited cousin to “take it easy.” It showed what nerve he had. He was getting desperate; and while he kept one eye upon Archie, and the other turned toward the farther end of the passage, he was calculating his chances for emptying his six-shooter among the Mexicans, before they could close around him. “There is nothing to be gained by being in such a hurry,” he added, as his cousin once more dropped the keys. “The more haste the less speed, you know.”

At this moment lights flashed in the passage, and dark forms came on at a rapid run. The prospect was certainly disheartening. Their only chance for escape was through that door, which refused to open for them, and there were their enemies, at least half a dozen of them, not more than twenty feet distant. But their good fortune had not yet deserted them. The right key was found, just in the nick of time—not a single instant too soon—the door flew open, and Frank and Archie, uttering a simultaneous cry of joy, slipped through and slammed it behind them. The moment it was closed Frank braced himself against it, and Archie inserted the key into the lock; but, before he could turn the bolt, a strong hand grasped the latch, and a stalwart Mexican threw his weight against the door, which was forced partly open, in spite of all Frank’s efforts to prevent it. A moment afterward, a hand holding a murderous looking bowie-knife appeared, followed first by a dark, scowling face, and then by a pair of broad shoulders. One of the Mexicans, who had reached the door a little in advance of his companions, was trying to squeeze himself into the the room; and he seemed in a fair way to accomplish his object.

“Here’s fifty thousand dollars,” said he, exultingly. “Come here, somebody. He’s got a pistol.”

The boys jammed the door against the Ranchero, with all their strength, but he was a match for both of them, and besides he had a great advantage. Frank and Archie could find no foothold upon the hard dirt floor. Their feet slipped about in every direction, and the Mexican, having braced himself against the door-post, was slowly but surely pushing them back. He would certainly have succeeded in working his way into the room, had it not been for Frank’s revolver. The sight of the cocked weapon, thrust full in his face, drove him back, and before the rest of the Mexicans could come to his assistance, the door was closed and fastened.

“Whew!” whispered Archie, drawing a long breath, and wiping the big drops of perspiration from his forehead, “that was a close shave, wasn’t it? It doesn’t seem to suit them very well.”

If one might judge by the uproar that arose in the passage, the Mexicans were certainly very much disappointed. They yelled at the top of their lungs, and some struck the door with their knives, while others threw themselves against it and tried to burst it open. But that door was not a common door. It was made of heavy planks, and was strong enough to successfully resist all their attacks. There was but one way in which they could effect an entrance, and that was by cutting the door down with an ax. Before that could be done, the fugitives would have ample time to hunt up a new hiding-place.

The boys had been so terrified by their recent danger, and so intent on preventing their enemies from following them into the room, that they had not thought of any thing else. They had not had time to look about the apartment in which they had taken refuge; and if there had been a dozen men in there, they would not have known it. As soon as they had somewhat recovered their composure, and satisfied themselves that their enemies in the passage-way could not immediately effect an entrance, they began an examination of the room, and found that, like most of the others in the underground portion of the rancho, it was used as a receptacle for various odds and ends, being filled with boxes, bales of goods, and articles of like description. They noticed also that the room communicated with another, and that the door between them stood wide open; and scarcely had they observed these points, before they became aware that there were men on the opposite side of that door. They could not see them, but they could distinctly hear their voices. One was angrily demanding something, and another was answering in an imploring tone. The men, whoever they were, had evidently got into some difficulty; for, with the voices, was occasionally mingled the sounds of a furious struggle.

“There’s a fight going on in there,” whispered Archie. “I hope they will keep one another employed until we can get out of here. Which way shall we go?”
