As soon as he thought he had made sufficient offing, Jack brought the _Fury_ closer to the wind and crept toward the line he had mentioned. He no longer expected to see any signal from the vessel; the lantern would be turned away from him. But he looked anxiously toward the shore. Minute after minute passed, and yet he saw nothing. He began to fear that either he had lost his bearings and crossed the line while signaling had been going on between the tower and the vessel, or that there was no one at the Folly, after all, and both he and the commander of the other ship were to be disappointed. Suddenly a light flashed out from shore, and remained gleaming brightly and steadily. So strong was it that Jack felt not a little anxiety lest it should show up the _Fury_ to the vessel now between her and the land. But a moment’s reflection reassured him. At this distance the light could have no illuminating power; and if he could not see the strange craft, it was not very likely that she could see him. He was wondering what his next move had better be when the light disappeared. But only for a moment. Then it shone out again. Again it disappeared, and then for several seconds it alternately came and went, with regular intervals of very brief duration between the flashes. At last there was a longer interval; then the regular flashes began again. "Heave to, Babbage!" cried Jack. Springing down to the cabin, he returned in a few moments with a slip of paper, a pencil, and a shaded lantern. By the light of the last, Jack made a note. It would not have conveyed much or anything to an onlooker. It began— 17 — 3 — 18 — 2 —— 1 — 17 — 17 — 3 — 20 — 2 —— 16 —— 11 —— 15 — 1 — 20 — 3 — 17 — 2 ... and this succession of numbers and dashes grew until it completely filled the paper. After he had written for nearly half an hour the light disappeared altogether; he waited ten minutes on the chance of the flashes being resumed; then folded the paper, put it in his pocket, and ordered the men to crowd on all sail. In a few seconds the _Fury_ was running before the wind in the direction Jack thought the strange vessel might have taken. There was just a chance that he might overhaul and capture her, for he guessed that she was little if anything larger than the cutter, and in all likelihood the same lugger which had escaped Lieutenant Blake months before. But though he cruised about for a couple of hours he failed to find her. "We’ll give it up," he said at length to Babbage. "Now I want a little time to work out a puzzle. We mustn’t be seen from Luscombe or the neighborhood, so we’ll beat down Channel and make for Falmouth. That’s far enough away to be out of reach of the Luscombe men or their spies; and I’ll eat my boots if I haven’t a pretty piece of news to report to Admiral Horniman to-morrow." *CHAPTER XIV* *A DISCOVERY*
