Owing probably to the softness of the ground, the sound of their approach was not audible within, and the cries increased as they drew nearer. Flinging their reins to the guide, whom nothing would have induced to join them, the Americans swung off their horses within a few yards of a lighted window, and ran forward. The sight which met their eyes within the casement was one which did not make Ned’s amazed exclamation seem out of place. “It’s Senorita Isabelle!” exclaimed Herc, as his eyes encountered the shrinking figure of a young woman in one corner of the lighted room. In front of her, with a drawn sword, was General de Guzman himself, his face convulsed with fury. In another corner of the place stood Charbonde and Hank Harkins holding back a venerable old lady, who appeared to have been on the point of precipitating herself upon the general. “For the last time, girl, will you tell me where that will is?” demanded the infuriated general in Spanish. “Never,” the girl bravely replied, “even though no one has heard my cries for help. I defy you to make me speak. The secret was imparted to me in confidence, and why should I tell you the whereabouts of the document? You only desire to possess yourself of it so that you may profit by wrongfully withholding our property.” “Then I shall make you a prisoner. My troops are now at the gates of Boca del Sierras. To-morrow they will enter it in triumph. I shall make it my first business to recapture those Americans, and shoot them in front of your eyes.” “Help! Help!” screamed the young woman, as the man advanced upon her. “Scream all you wish to, my dear niece. There is nobody to hear you!” exclaimed de Guzman, with an evil leer. The moment for revealing themselves had arrived. With a yell the Americans leaped the low sill of the open window and dashed into the room. A blow of Ned’s fist sent the general sprawling in a most undignified position into a corner of the room. Herc disposed of their old friend, Hank Harkins, while the impact of Stanley’s mighty fist sounded on the jaw of Chawedbones, as the sailor insisted on calling him. As for the girl, she seemed about to faint, but somehow Midshipman Stark’s arms happened to be convenient as she staggered back. [Illustration: With a yell the Americans leaped the low sill of the open window and dashed into the room.] The naval men’s borrowed revolvers came in handy at that moment, for all the tormentors of the two women were armed. Under the menacing muzzles of the Americans’ pistols, however, they were speedily disarmed. In fact, their amazement at the sudden appearance of the quartette in that place, and in such an hour, had almost bereft the others of their senses. By de Guzman and by the others, who had witnessed the sinking of the boat in which the Americans were escaping, it had been confidently assumed that they were all dead. Of the part they had played against the insurgents in the last few hours de Guzman was, of course, unaware.
