The calculations of the distance, of the necessary elevation and direction, and of the degree of motor-power required, were made with careful exactness, and when the proper instant arrived the button was touched, and the shot with which the cannon was charged was instantaneously removed to a point in the ocean about a mile beyond the Adamant, accompanied by a large portion of the heavy boom at which the gun had been aimed.
The cannon which had been suspended from the end of this boom fell into the sea, and would have crashed down upon the roof of Crab K, had not that vessel, in obedience to a signal from the repeller, loosened its hold upon the Adamant and retired a short distance astern. Material injury might not have resulted from the fall of this great mass of metal upon the crab, but it was considered prudent not to take useless risks.
The officers of the Adamant were greatly surprised and chagrined by the fall of their gun, with which they had expected ultimately to pound in the roof of the crab. No damage had been done to the vessel except the removal of a portion of the boom, with some of the chains and blocks attached, and no one on board the British ship imagined for a moment that this injury had been occasioned by the distant repeller. It was supposed that the constant firing of the cannon had cracked the boom, and that it had suddenly snapped.
Even if there had been on board the Adamant the means for rigging up another arrangement of the kind for perpendicular artillery practice, it would have required a long time to get it into working order, and the director of Repeller No. 7 hoped that now the British captain would see the uselessness of continued resistance.
But the British captain saw nothing of the kind, and shot after shot from his guns were hurled high into the air, in hopes that the great curves described would bring some of them down on the deck of the repeller. If this beastly store-ship, which could stand fire but never returned it, could be sunk, the Adamant's captain would be happy. With the exception of the loss of her motive power, his vessel was intact, and if the stupid crab would only continue to keep the Adamant's head to the sea until the noise of her cannonade should attract some other British vessel to the scene, the condition of affairs might be altered.
All that day the great guns of the Adamant continued to roar. The next morning, however, the firing was not resumed, and the officers of the repeller were greatly surprised to see approaching from the British ship a boat carrying a white flag. This was a very welcome sight, and the arrival of the boat was awaited with eager interest.
During the night a council had been held on board the Adamant. Her cannonading had had no effect, either in bringing assistance or in injuring the enemy; she was being towed steadily southward farther and farther from the probable neighbourhood of a British man-of-war; and it was agreed that it would be the part of wisdom to come to terms with the Syndicate's vessel.
Therefore the captain of the Adamant sent a letter to the repeller, in which he stated to the persons in charge of that ship, that although his vessel had been injured in a manner totally at variance with the rules of naval warfare, he would overlook this fact and would agree to cease firing upon the Syndicate's vessels, provided that the submerged craft which was now made fast to his vessel should attach itself to the Adamant's bow, and by means of a suitable cable which she would furnish, would tow her into British waters. If this were done he would guarantee that the towing craft should have six hours in which to get away.
When this letter was read on board the repeller it created considerable merriment, and an answer was sent back that no conditions but those of absolute surrender could be received from the British ship.
In three minutes after this answer had been received by the captain of the Adamant, two shells went whirring and shrieking through the air toward Repeller No. 7, and after that the cannonading from the bow, the stern, the starboard, and the port guns of the great battle-ship went on whenever there was a visible object on the ocean which looked in the least like an American coasting vessel or man-of-war.
