For answer Journegan switched off the lights for few seconds. Mr. Jones and Mr. Jackson watched the water steadily, but nothing broke its now black surface.
"It's getting warm now," called Mr. Smithe, and on the instant Journegan switched on the lights again. They all sat there for some minutes awaiting the result but the water gave no token save that now the cloth had disappeared from the end of the wire and as the minutes dragged by Mr. Smithe called attention to this fact.
"You see, it has begun to work," he called, pointing below at the invisible wire. "In a moment I shall pull it up—a few dollars worth of metal is all we need wait for to-night. I have an engagement at the Casino at ten."
Suddenly he pulled up the wire. Upon its end, fixed fast and apparently imbedded, was a small mass of a peculiar metal, bright, shiny and unmistakably gold. Yes, he had done it. He had made the sea give up its own. There it was, gold, pure gold in an ingot Worth about forty dollars. The astounded Mr. Jones gazed in wonder. The skeptical Mr. Jackson let his eyes open wide. It was certainly the wonder of the era. It was tremendous.
"You can take this specimen and have it assayed," said Mr. Smithe, handing the nugget to Mr. Jackson; "you can return it at your convenience."
When Mr. Smithe struck the blows with the hammer, thereby causing the current to flow, it roused Bahama Bill from his drowsing in the bottom of a small boat close to the shore. He grinned and arose. He had been told just what to do and paid heavily for keeping his mouth shut about doing it. It was none of his business why they did these things, it was his business to dive for money, no matter what the affair. He was well paid and he saw no reason why he should not take the money. A man of more refined mind would have possibly refused the work, but Bahama Bill was brought up in the school where it was necessary to live, necessary to have the means to live without going too far outside the rules of the game. It was Journegan's business to make gold out of sea-water. It was his to do a bit of diving for him and perform certain feats which might or might not affect the pockets of the gentlemen now waiting to see the result. There were so many questionable ways of separating folks from their coin that he was amused at the graft of these two. At the gambling house kept by the pious and strict manager of the hotel, there were many ways of separating folks from their cash. It had the sanction of the "Boss"—that was the only difference he could see in the matter. He was a plain wrecker, a man who made his living from the misfortunes of others. Yet it was a legitimate business, and he generally played fair. He was simply a big, powerful man, a giant diver of the Bank. He dropped his trousers and stood forth naked in the darkness as the last banging of the hammer died away. It was the signal agreed upon and without a moment's hesitation he made a long clean dive into the dark water. Coming to the surface he swam quickly and noiselessly toward the end of the dock where the gate, or opening in the piling, would allow him to get within the enclosure. He was a little doubtful of finding the end of the wire, as he had been instructed to, but he thought the white cloth might make it visible, for the water was very clear.
He never fancied swimming at night over the coral banks, for there were always many denizens of the ocean that came in and either rested or fed during the hours of darkness. Many a big shark lay log-wise in the waters of the reef during the night, waiting for a rush upon the feeding mullet or other small fry. He had found sharks always dangerous at this season of the year, and he was now without even a knife. However, he managed to reach opposite the opening without mishap. Then he floated silently and took a few deep breaths for the work in hand.
He could hear the voices of the men within the enclosure and he heard Mr. Smithe announce that the wire was ready. He was just about to dive when a disturbance in the sea close to him made him hesitate and turn. A triangular fin cut the surface not two fathoms distant. It was that of a gigantic shark. Instantly the diver went under and strove with mighty strokes to gain the opening in the piling. He felt instinctively that the monster would follow him, but it was the nearest place of refuge. Guided solely by memory of direction, he fairly tore through the water, struck the opening with his hand and with a mighty effort swung himself within, remaining under and shooting ahead with the momentum of his flight. A commotion, a sweep of a strong current at the gate told of a passing heavy body, but nothing touched him. He could not hold his breath much longer on account of the sudden effort, and he was sworn not to come to the surface within the piles. It was at this moment that Mr. Smithe, seeing something of what had occurred by the shadows beneath the surface, called for more electricity, and Journegan with his rare presence of mind switched off the lights. Bahama Bill came to the surface gently, and had it not been for the noisy conversation of Smithe, his deep breathing would surely have made his presence known to all. As it was he lay upon his back, close within the shadow of the piling and just let his nose come into the air. In a few moments he had regained his wind and sank downward to the end of the wire. Then Mr. Smithe switched on the light and announced that the wire was warm. It was a close call, close in more ways than one, but the mate had made good, he had done his part. He saw the white cloth without difficulty and attached the piece of gold. Then he fled for the open with a courage which might have called forth the admiration of the watchers had they known his danger.
Once clear, he swam silently and with all his strength for the small boat. The feeling that something was pursuing him kept him nerved to the utmost. He fairly tore through the sea, but only raised his head every twenty to thirty feet to breathe. He swam almost all the way under water. This he knew was the safest, for the predatory denizens of the coral banks depend as much on hearing, or a sense akin to it, as on sight. The feeling that something still followed drove him along at his top speed, but he could see nothing, know nothing of its shape or form. It was just the instinctive fear, or nerve straining one feels in the dark where danger lurks. He gained the small boat quickly and at that instant a great shadow swept past leaving a trail of phosphorescent fire in its wake.
"If you gentlemen are satisfied, we will now go back to the hotel," said Mr. Smithe with his most urbane manner. "If at any other time you would like a renewal of the test, we shall be only too glad to give it, provided of course, neither you nor your guests talk of the process and thus set curious people at work to find out our secret."
