The British officers were shown the motor-bomb to be discharged, which, externally, was very much like an ordinary shell, except that it was nearly as long as the bore of the cannon; and the director stated that although, of course, the principle of the motor-bomb was the Syndicate's secret, it was highly desirable that its effects and its methods of operation should be generally known. The repeller, accompanied by the mail steamer and all the crabs, now moved to about two miles to the leeward of the Craglevin, and lay to. The motor-bomb was then placed in one of the great guns, while the scientific corps attended to the necessary calculations of distance, etc. The director now turned to the British captain, who had been observing everything with the greatest interest, and, with a smile, asked him if he would like to commit hari-kari? As this remark was somewhat enigmatical, the director went on to say that if it would be any gratification to the captain to destroy his vessel with his own hands, instead of allowing this to be done by an enemy, he was at liberty to do so. This offer was immediately accepted, for if his ship was really to be destroyed, the captain felt that he would like to do it himself. When the calculations had been made and the indicator set, the captain was shown the button he must press, and stood waiting for the signal. He looked over the sea at the Craglevin, which had settled a little at the stern, and was rolling heavily; but she was still a magnificent battleship, with the red cross of England floating over her. He could not help the thought that if this motor mystery should amount to nothing, there was no reason why the Craglevin should not be towed into port, and be made again the grand warship that she had been. Now the director gave the signal, and the captain, with his eyes fixed upon his ship, touched the button. A quick shock ran through the repeller, and a black-gray cloud, half a mile high, occupied the place of the British ship. The cloud rapidly settled down, covering the water with a glittering scum which spread far and wide, and which had been the Craglevin. The British captain stood for a moment motionless, and then he picked up a rammer and ran it into the muzzle of the cannon which had been discharged. The great gun was empty. The instantaneous motor-bomb was not there. Now he was convinced that the Syndicate had not mined the fortresses which they had destroyed. In twenty minutes the two British officers were on board the transport, which then steamed rapidly westward. The crabs again took the repeller in tow, and the Syndicate's fleet continued its eastward course, passing through the wide expanse of glittering scum which had spread itself upon the sea. They were not two-thirds of their way across the Atlantic when the transport reached St. John's, and the cable told the world that the Craglevin had been annihilated.
