Hardly had the British cruiser come well in sight than a puff of smoke rose from the deck of the other warship, and a shell came whistling through the air, and burst within a hundred yards of the _Lurline_. Twenty-four hours ago Tremayne had been one of the richest men in England, and just now he would have willingly given all that he had possessed to be twenty-five miles further to the south-westward than he was. Another shell from the Frenchman passed clear over the _Lurline_, and plunged into the water and burst, throwing a cloud of spray high into the air. Then came one from the torpedo-boat, but she was still too far off for her light gun to do any damage, and the projectile fell spent into the sea nearly five hundred yards short. Immediately after this came a third shell from the French cruiser, and this, by an unlucky chance, struck the forecastle of the yacht, burst, and tore away several feet of the bulwarks, and, worse than all, killed four of her crew instantly. "First blood!" said Tremayne to himself through his clenched teeth. "That shall be an unlucky shot for you, my friend, if we reach the air-ship before you sink us." Meanwhile the two cruisers, each approaching the other at a speed of more than twenty miles an hour, had got within shot. A puff of smoke spurted out from the side of the latest comer. The well-aimed projectile passed fifty yards astern of the _Lurline_, and struck the advancing torpedo-boat square on the bow. The next instant it was plainly apparent that there was nothing more to be feared from her. The solid shot had passed clean through her two sides. Her nose went down and her stern came up. Then bang went another gun from the British cruiser. This time the messenger of death was a shell. It struck the inclined deck amidships, there was a flash of flame, a cloud of steam rose up from her bursting boilers, and then she broke in two and vanished beneath the smooth-rolling waves. Two minutes later the duel began in deadly earnest. The tricolor ran up to the masthead of the French cruiser, and jets of mingled smoke and flame spurted one after the other from her sides, and shells began bursting in quick succession round the rapidly-advancing Englishman. Evidently the Frenchman, with his remaining torpedo-boat, thought himself a good match for the British cruiser, for he showed no disposition to shirk the combat, despite the fact that he was so near to the cruising ground of a powerful squadron. As the two cruisers approached each other, the fire from their heavy guns was supplemented by that of their light quick-firing armament, until each of them became a floating volcano, vomiting continuous jets of smoke and flame, and hurling showers of shot and shell across the rapidly-lessening space between them.
