This projectile was not, in the ordinary sense of the word, an explosive, and was named by its inventors, "The Instantaneous Motor." It was discharged from an ordinary cannon, but no gunpowder or other explosive compound was used to propel it.The bomb possessed, in itself the necessary power of propulsion, and the gun was used merely to give it the proper direction.
These bombs were cylindrical in form, and pointed at the outer end.They were filled with hundreds of small tubes, each radiating outward from a central line.Those in the middle third of the bomb pointed directly outward, while those in its front portion were inclined forward at a slight angle, and those in the rear portion backward at the same angle.One tube at the end of the bomb, and pointing directly backward, furnished the motive power.
Each of these tubes could exert a force sufficient to move an ordinary train of passenger cars one mile, and this power could be exerted instantaneously, so that the difference in time in the starting of a train at one end of the mile and its arrival at the other would not be appreciable.The difference in concussionary force between a train moving at the rate of a mile in two minutes, or even one minute, and another train which moves a mile in an instant, can easily be imagined.
Inthesebombs,thosetubeswhichmightdirecttheirpowersdownward or laterally upon the earth were capable of instantaneously propelling every portion of solid ground or rock to a distance of two or three hundred yards, while the particles of objects on the surface of the earth were instantaneously removed to a far greater distance.The tube which propelled the bomb was of a force graduated according to circumstances, and it would carry a bomb to as great a distance as accurate observation for purposes of aim could be made.Its force was brought into action while in the cannon by means of electricity while the same effect was produced in the other tubes by the concussion of the steel head against the object aimed at.
What gave the tubes their power was the jealously guarded secret.
The method of aiming was as novel as the bomb itself.In this process nothing depended on the eyesight of the gunner; the personal equation was entirely eliminated.The gun was so mounted that its direction was accurately indicated by graduated scales; there was an instrument which was acted upon by the dip, rise, or roll of the vessel, and which showed at any moment the position of the gun with reference to the plane of the sea- surface.
Before the discharge of the cannon an observation was taken by one of the scientific men, which accurately determined the distance to the object to be aimed at, and reference to a carefully prepared mathematical table showed to what points on the graduated scales the gun should be adjusted, and the instant that the that the muzzle of the cannon was in the position that it was when the observation was taken, a button was touched and the bomb was instantaneously placed on the spot aimed at.The exactness with which the propelling force of the bomb could be determined was an important factor in this method of aiming.
As soon as three of the spring-armoured vessels and five "crabs" were completed, the Syndicate felt itself ready to begin operations.It was indeed time.The seas had been covered with American and British merchantmen hastening homeward, or to friendly ports, before the actual commencement of hostilities.But all had not been fortunate enough to reach safety within the limits of time allowed, and several American merchantmen had been already captured by fast British cruisers.
The members of the Syndicate well understood that if a war was to be carried on as they desired, they must strike the first real blow.Comparatively speaking, a very short time had elapsed since the declaration of war, and the opportunity to take the initiative was still open.It was in order to take this initiative that, in the early hours of a July morning, two of the Syndicate's armoured vessels, each accompanied by a crab, steamed out of a New England port, and headed for the point on the Canadian coast where it had been decided to open the campaign.
The vessels of the Syndicate had no individual names.The spring- armoured ships were termed "repellers," and were numbered, and the crabs were known by the letters of the alphabet.Each repeller was in charge of a Director of Naval Operations; and the whole naval force of the Syndicate was under the command of a Director-in-chief.On this momentous occasion this officer was on board of Repeller No.1, and commanded the little fleet.
The repellers had never been vessels of great speed, and their present armour of steel strips, the lower portion of which was frequently under water, considerably retarded their progress; but each of them was taken in tow by one of the swift and powerful crabs, and with this assistance they made very good time, reaching their destination on the morning of the second day.
It was on a breezy day, with a cloudy sky, and the sea moderately smooth, that the little fleet of the Syndicate lay to off the harbour of one of the principal Canadian seaports.About five miles away the headlands on either side of the mouth of the harbour could be plainly seen.It had been decided that Repeller No.1 should begin operations.Accordingly, that vessel steamed about a mile nearer the harbour, accompanied by Crab A.The other repeller and crab remained in their first position, ready to act in case they should be needed.
