Valiantly the boats beset the crabs, keeping up a constant fusillade, and endeavouring to throw grapnels over them. If one of these should catch under an overlapping armour-plate it could be connected with the steam windlass of the Adamant, and a plate might be ripped off or a crab overturned.

But the crabs proved to be much more lively fish than their enemies had supposed. Turning, as if on a pivot, and darting from side to side, they seemed to be playing with the boats, and not trying to get away from them. The spring armour of Crab K interfered somewhat with its movements, and also put it in danger from attacks by grapnels, and it therefore left most of the work to its consort.

Crab J, after darting swiftly in and out among her antagonists for some time, suddenly made a turn, and dashing at one of the boats, ran under it, and raising it on its glistening back, rolled it, bottom upward, into the sea. In a moment the crew of the boat were swimming for their lives. They were quickly picked up by two of the other boats, which then deemed it prudent to return to the ship.

But the second officer of the Adamant, who commanded the fourth boat, did not give up the fight. Having noted the spring armour of Crab K, he believed that if he could get a grapnel between its steel ribs he yet might capture the sea-monster. For some minutes Crab K contented itself with eluding him; but, tired of this, it turned, and raising its huge nippers almost out of the water, it seized the bow of the boat, and gave it a gentle crunch, after which it released its hold and retired. The boat, leaking rapidly through two ragged holes, was rowed back to the ship, which it reached half full of water.

The great battle-ship, totally bereft of the power of moving herself, was now rolling in the trough of the sea, and a signal came from the repeller for Crab K to make fast to her and put her head to the wind. This was quickly done, the crab attaching itself to the stern-post of the Adamant by a pair of towing nippers. These were projected from the stern of the crab, and were so constructed that the larger vessel did not communicate all its motion to the smaller one, and could not run down upon it.

As soon as the Adamant was brought up with her head to the wind she opened fire upon the repeller. The latter vessel could easily have sailed out of the range of a motionless enemy, but her orders forbade this. Her director had been instructed by the Syndicate to expose his vessel to the fire of the Adamant's heavy guns. Accordingly the repeller steamed nearer, and turned her broadside toward the British ship.

Scarcely had this been done when the two great bow guns of the Adamant shook the air with tremendous roars, each hurling over the sea nearly a ton of steel. One of these great shot passed over the repeller, but the other struck her armoured side fairly amidship. There was a crash and scream of creaking steel, and Repeller No. 7 rolled over to windward as if she had been struck by a heavy sea. In a moment she righted and shot ahead, and, turning, presented her port side to the enemy. Instant examination of the armour on her other side showed that the two banks of springs were uninjured, and that not an air-buffer had exploded or failed to spring back to its normal length.

Firing from the Adamant now came thick and fast, the crab, in obedience to signals, turning her about so as to admit the firing of some heavy guns mounted amidships. Three enormous solid shot struck the repeller at different points on her starboard armour without inflicting damage, while the explosion of several shells which hit her had no more effect upon her elastic armour than the impact of the solid shot.

It was the desire of the Syndicate not only to demonstrate to its own satisfaction the efficiency of its spring armour, but to convince Great Britain that her heaviest guns on her mightiest battle-ships could have no effect upon its armoured vessels. To prove the absolute superiority of their means of offence and defence was the supreme object of the Syndicate. For this its members studied and worked by day and by night; for this they poured out their millions; for this they waged war. To prove what they claimed would be victory.

When Repeller No. 7 had sustained the heavy fire of the Adamant for about half an hour, it was considered that the strength of her armour had been sufficiently demonstrated; and, with a much lighter heart than when he had turned her broadside to the Adamant, her director gave orders that she should steam out of the range of the guns of the British ship. During the cannonade Crab J had quietly slipped away from the vicinity of the Adamant, and now joined the repeller.

The great ironclad battle-ship, with her lofty sides plated with nearly two feet of solid steel, with her six great guns, each weighing more than a hundred tons, with her armament of other guns, machine cannon, and almost every appliance of naval warfare, with a small army of officers and men on board, was left in charge of Crab K, of which only a few square yards of armoured roof could be seen above the water. This little vessel now proceeded to tow southward her vast prize, uninjured, except that her rudder and propeller- blades were broken and useless.

Although the engines of the crab were of enormous power, the progress made was slow, for the Adamant was being towed stern foremost. It would have been easier to tow the great vessel had the crab been attached to her bow, but a ram which extended many feet under water rendered it dangerous for a submerged vessel to attach itself in its vicinity.

During the night the repeller kept company, although at a considerable distance, with the captured vessel; and early the next morning her director prepared to send to the Adamant a boat with a flag-of-truce, and a letter demanding the surrender and subsequent evacuation of the British ship. It was supposed that now, when the officers of the Adamant had had time to appreciate the fact that they had no control over the movements of their vessel; that their armament was powerless against their enemies; that the Adamant could be towed wherever the Syndicate chose to order, or left helpless in midocean,--they would be obliged to admit that there was nothing for them to do but to surrender.

But events proved that no such ideas had entered the minds of the Adamant's officers, and their action totally prevented sending a flag-of-truce boat. As soon as it was light enough to see the repeller the Adamant began firing great guns at her. She was too far away for the shot to strike her, but to launch and send a boat of any kind into a storm of shot and shell was of course impossible.

The cannon suspended over the stern of the Adamant was also again brought into play, and shot after shot was driven down upon the towing crab. Every ball rebounded from the spring armour, but the officer in charge of the crab became convinced that after a time this constant pounding, almost in the same place, would injure his vessel, and he signalled the repeller to that effect.

The director of Repeller No. 7 had been considering the situation. There was only one gun on the Adamant which could be brought to bear upon Crab K, and it would be the part of wisdom to interfere with the persistent use of this gun. Accordingly the bow of the repeller was brought to bear upon the Adamant, and her motor gun was aimed at the boom from which the cannon was suspended.

The projectile with which the cannon was loaded was not an instantaneous motor-bomb. It was simply a heavy solid shot, driven by an instantaneous motor attachment, and was thus impelled by the same power and in the same manner as the motor-bombs. The instantaneous motor-power had not yet been used at so great a distance as that between the repeller and the Adamant, and the occasion was one of intense interest to the small body of scientific men having charge of the aiming and firing.

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.
