The two crabs now took the steel net from its moorings and carried it up the harbour. This was rather difficult on account of the islands, rocks, and sand-bars; but the leading crab had on board a pilot acquainted with those waters. With the net hanging between them, the two submerged vessels, one carefully following the other, reached a point about two miles below the city, where the net was anchored across the harbour. It did not reach from shore to shore, but in the course of the morning two other nets, designed for shallower waters, were brought from the repellers and anchored at each end of the main net, thus forming a line of complete protection against submarine torpedoes which might be sent down from the upper harbour.

Repeller No. 1 now steamed into the harbour, accompanied by Crab A, and anchored about a quarter of a mile seaward of the net. The other repeller, with her attendant crab, cruised about the mouth of the harbour, watching a smaller entrance to the port as well as the larger one, and thus maintaining an effective blockade. This was not a difficult duty, for since the news of the extraordinary performances of the crabs had been spread abroad, no merchant vessel, large or small, cared to approach that port; and strict orders had been issued by the British Admiralty that no vessel of the navy should, until further instructed, engage in combat with the peculiar craft of the Syndicate. Until a plan of action had been determined upon, it was very desirable that English cruisers should not be exposed to useless injury and danger.

This being the state of affairs, a message was sent from the office of the Syndicate across the border to the Dominion Government, which stated that the seaport city which had been attacked by the forces of the Syndicate now lay under the guns of its vessels, and in case of any overt act of war by Great Britain or Canada alone, such as the entrance of an armed force from British territory into the United States, or a capture of or attack upon an American vessel, naval or commercial, by a British man-of-war, or an attack upon an American port by British vessels, the city would be bombarded and destroyed.

This message, which was, of course, instantly transmitted to London, placed the British Government in the apparent position of being held by the throat by the American War Syndicate. But if the British Government, or the people of England or Canada, recognized this position at all, it was merely as a temporary condition. In a short time the most powerful men-of-war of the Royal Navy, as well as a fleet of transports carrying troops, would reach the coasts of North America, and then the condition of affairs would rapidly be changed. It was absurd to suppose that a few medium-sized vessels, however heavily armoured, or a few new-fangled submarine machines, however destructive they might be, could withstand an armada of the largest and finest armoured vessels in the world. A ship or two might be disabled, although this was unlikely, now that the new method of attack was understood; but it would soon be the ports of the United States, on both the Pacific and Atlantic coasts, which would lie under the guns of an enemy.

But it was not in the power of their navy that the British Government and the people of England and Canada placed their greatest trust, but in the incapacity of their petty foe to support its ridiculous assumptions. The claim that the city lay under the guns of the American Syndicate was considered ridiculous, for few people believed that these vessels had any guns. Certainly, there had been no evidence that any shots had been fired from them. In the opinion of reasonable people the destruction of the forts and the explosions in the harbour had been caused by mines-- mines of a new and terrifying power--which were the work of traitors and confederates. The destruction of the lighthouse had strengthened this belief, for its fall was similar to that which would have been occasioned by a great explosion under its foundation.

But however terrifying and appalling had been the results of the explosion of these mines, it was not thought probable that there were any more of them. The explosions had taken place at exposed points distant from the city, and the most careful investigation failed to discover any present signs of mining operations.

This theory of mines worked by confederates was received throughout the civilized world, and was universally condemned. Even in the United States the feeling was so strong against this apparent alliance between the Syndicate and British traitors, that there was reason to believe that a popular pressure would be brought to bear upon the Government sufficient to force it to break its contract with the Syndicate, and to carry on the war with the National army and navy. The crab was considered an admirable addition to the strength of the navy, but a mine under a fort, laid and fired by perfidious confederates, was considered unworthy an enlightened people.

The members of the Syndicate now found themselves in an embarrassing and dangerous position--a position in which they were placed by the universal incredulity regarding the instantaneous motor; and unless they could make the world believe that they really used such a motor-bomb, the war could not be prosecuted on the plan projected.

It was easy enough to convince the enemy of the terrible destruction the Syndicate was able to effect; but to make that enemy and the world understand that this was done by bombs, which could be used in one place as well as another, was difficult indeed. They had attempted to prove this by announcing that at a certain time a bomb should be projected into a certain fort. Precisely at the specified time the fort had been destroyed, but nobody believed that a bomb had been fired.

Every opinion, official or popular, concerning what it had done and what might be expected of it, was promptly forwarded to the Syndicate by its agents, and it was thus enabled to see very plainly indeed that the effect it had desired to produce had not been produced. Unless the enemy could be made to understand that any fort or ships within ten miles of one of the Syndicate's cannon could be instantaneously dissipated in the shape of fine dust, this war could not be carried on upon the principles adopted, and therefore might as well pass out of the hands of the Syndicate.

Day by day and night by night the state of affairs was anxiously considered at the office of the Syndicate in New York. A new and important undertaking was determined upon, and on the success of this the hopes of the Syndicate now depended.

During the rapid and vigorous preparations which the Syndicate were now making for their new venture, several events of interest occurred.

Two of the largest Atlantic mail steamers, carrying infantry and artillery troops, and conveyed by two swift and powerful men-of-war, arrived off the coast of Canada, considerably to the north of the blockaded city. The departure and probable time of arrival of these vessels had been telegraphed to the Syndicate, through one of the continental cables, and a repeller with two crabs had been for some days waiting for them. The English vessels had taken a high northern course, hoping they might enter the Gulf of St. Lawrence without subjecting themselves to injury from the enemy's crabs, it not being considered probable that there were enough of these vessels to patrol the entire coast. But although the crabs were few in number, the Syndicate was able to place them where they would be of most use; and when the English vessels arrived off the northern entrance to the gulf, they found their enemies there.

However strong might be the incredulity of the enemy regarding the powers of a repeller to bombard a city, the Syndicate felt sure there would be no present invasion of the United States from Canada; but it wished to convince the British Government that troops and munitions of war could not be safely transported across the Atlantic. On the other hand, the Syndicate very much objected to undertaking the imprisonment and sustenance of a large body of soldiers. Orders were therefore given to the officer in charge of the repeller not to molest the two transports, but to remove the rudders and extract the screws of the two war-vessels, leaving them to be towed into port by the troop-ships.

This duty was performed by the crabs, while the British vessels, both rams, were preparing to make a united and vigorous onset on the repeller, and the two men-of-war were left hopelessly tossing on the waves. One of the transports, a very fast steamer, had already entered the straits, and could not be signalled; but the other one returned and took both the war-ships in tow, proceeding very slowly until, after entering the gulf, she was relieved by tugboats.

Another event of a somewhat different character was the occasion of much excited feeling and comment, particularly in the United States. The descent and attack by British vessels on an Atlantic port was a matter of popular expectation. The Syndicate had repellers and crabs at the most important points; but, in the minds of naval officers and a large portion of the people, little dependence for defence was to be placed upon these. As to the ability of the War Syndicate to prevent invasion or attack by means of its threats to bombard the blockaded Canadian port, very few believed in it. Even if the Syndicate could do any more damage in that quarter, which was improbable, what was to prevent the British navy from playing the same game, and entering an American seaport, threaten to bombard the place if the Syndicate did not immediately run all their queer vessels high and dry on some convenient beach?

A feeling of indignation against the Syndicate had existed in the navy from the time that the war contract had been made, and this feeling increased daily. That the officers and men of the United States navy should be penned up in harbours, ports, and sounds, while British ships and the hulking mine-springers and rudder-pinchers of the Syndicate were allowed to roam the ocean at will, was a very hard thing for brave sailors to bear. Sometimes the resentment against this state of affairs rose almost to revolt.

The great naval preparations of England were not yet complete, but single British men-of-war were now frequently seen off the Atlantic coast of the United States. No American vessels had been captured by these since the message of the Syndicate to the Dominion of Canada and the British Government. But one good reason for this was the fact that it was very difficult now to find upon the Atlantic ocean a vessel sailing under the American flag. As far as possible these had taken refuge in their own ports or in those of neutral countries.

At the mouth of Delaware Bay, behind the great Breakwater, was now collected a number of coastwise sailing-vessels and steamers of various classes and sizes; and for the protection of these maritime refugees, two vessels of the United States navy were stationed at this point. These were the Lenox and Stockbridge, two of the finest cruisers in the service, and commanded by two of the most restless and bravest officers of the American navy.

The appearance, early on a summer morning, of a large British cruiser off the mouth of the harbour, filled those two commanders with uncontrollable belligerency. That in time of war a vessel of the enemy should be allowed, undisturbed, to sail up and down before an American harbour, while an American vessel filled with brave American sailors lay inside like a cowed dog, was a thought which goaded the soul of each of these commanders. There was a certain rivalry between the two ships; and, considering the insult offered by the flaunting red cross in the offing, and the humiliating restrictions imposed by the Naval Department, each commander thought only of his own ship, and not at all of the other.
