The other stared thoughtfully at the cigar which remained poised in his lean fingers. Then he raised his brilliant eyes, and the Englishman realized that the moment of lightness, of almost schoolboyish delight at the sense of danger had entirely passed. The eyes shone passionately, and reminded him sharply of the expressive eyes of the woman who had appealed for humanity with him on the brink of the Yorkshire cliffs. "Why? Because I have convinced you of my submersible. Because for that reason I have determined to deprive the German Government of the use of my U-rays for an indefinite period. Perhaps forever. Listen, there is only one man knows that I have an installation of that light on my ship besides ourselves, and that man is--Ludovic. I have installed it with my own hands. The installation on the submersible dreadnought which you saw was the first effort in that direction, and the Government believe it to be purely experimental. Well, the experiment has--failed. That is all." He shrugged. "But you will be forced to try again." "And it will fail--again. Ach, so! I would rather unship my plant, and fling my models to the bottom of the sea, where they may help to light up the world of crabs, than that my Government should acquire one single added threat against humanity." The next few moments were silently occupied in lighting their cigars. Ruxton had no words with which to answer him. He was thinking deeply, comparing this man's attitude towards the country which claimed him with his own feelings for his island home. He wondered what his attitude would have been had their positions been reversed; if he, as an Englishman, had been such a power, through his discoveries, for aiding his country. To his shame he was forced to the conclusion that this white-haired Pole was a greater man than he could ever hope to be. The difference between them lay in the difference between a perfervid patriotism, and the Prince's overwhelming love of humanity inspired by the abyss of horror into which a blind devotion to his country had flung him. This man had passed the great dividing line where the uplifted spirit renounces the claims of earthly passion in favor of the call of the voice of the soul. The cause of humanity now dominated every other emotion. Somehow his own fervor of patriotism suffered severely by the comparison, and so he found himself with no words in which to answer. The old man rose from his chair and passed into his private stateroom. A few moments later he returned with two rolls of papers, neatly secured by tapes and seals. He had closed the door. He was about to cross over to his guest. But in a moment he was held rigid where he stood. A dull boom roared out somewhere overhead and vibrated down the entire length of the vessel. His eyes were wide and attentive. But there was no fear in them. Ruxton started up from the lounge on which he had been sitting. A thrilling excitement shone in his eyes.
