"By which time half the American fleet may have been destroyed for lack of warning," groaned Ridge. Then he added, his face blazing with anger: "I hope you are not an American, and I don't believe you can be, for you are a traitor, a coward, and a contemptible cur. I only hope I may meet you again some time when I am off duty, and can give you the thrashing you deserve." "All right, my young mud-lark," replied the Captain. "I'll give you a dose of medicine whenever you want it. Now clear out of here, and don't let me catch sight of you again!" Ridge did not hear these last words, for he was already walking rapidly aft, filled with a tumult of rage and perplexity. What ought he to do? What could he do? Was ever any one so utterly helpless in a crisis of such importance? Not until he reached the extreme after part of the ship did a ray of light break upon the situation. Then he caught sight of a yacht steaming swiftly into the harbor. She might be a despatch-boat, or a destroyer, or any one of half a dozen things; but whatever she was, she could help him if she only would. Close at hand was a jack-staff upholding an American ensign. Acting upon the impulse of his despair. Ridge hauled down this flag, and then half-masted it, union down, thus making a signal of distress that called for prompt aid from any vessel sighting it. Then he gazed eagerly at the swiftly approaching yacht. She must have noticed his signal, for she was now headed directly for the transport, and Ridge, clinging with one hand to an awning stanchion as he stood on the rail, frantically waved his hat. Suddenly a bellow of rage close at hand caused him to look in-board. The Captain of the transport, his face purple with passion, was rushing towards the jack-staff. "How dare you hoist the signal of a mutiny?" he howled. "I'll show--" "Because there is one on board," shouted Ridge, springing in front of the infuriated man, and at the same moment whipping out his revolver. "Halt where you are!" he added, fiercely. "For if you dare touch that flag before I am through with it I will blow out your traitorous brains!" The Captain, cowed by the steadily levelled muzzle of that pistol, obeyed this order and stood still; but at the same time he yelled for any of the transport's crew who might be within hearing to tumble aft in a hurry. In another minute they came--mates, deck-hands, engineers, stewards, and stokers--blocking the narrow gangways on either side of the deck-house. But beyond this they dared not go; for they too were confronted by that levelled pistol, and its holder's assurance that he would fire at the first man who advanced another step.
