 they bore an immense net, three or four hundred feet long and thirty feet deep, composed of jointed steel rods Along the upper edge of this net was series of air floats, which were so graduated that they were sunk by the weight of the net few feet below the surface of the water. from which position they held the net suspended vertically.
 This net, which was intended to pro- tect the repeller against the approach of submarine torpedoes which might be directed from the shore, was anchored at each end, two very small buoys indi- eating it's position. The crabs then fall ing astern, Repeller No. lay to, with the sunken net between her and the shore, and prepared to project the first instantaneous motor bomb ever used in warfare.
 The great gun In the bow of the vessel was loaded with one of the largest and most powerful motor bombs; and the spot to be aimed at was selected. This was a point in the water just inside of the mouth of the hnrbor, and nearly a mile from the land on either side. The distance of this point from the vessel be- ing calculated, the cannon was adjusted at the angle called for by the scale of distances and levels, and the instrument indicating rise, fall and direction was then put in connection with it.
 Now the director-in-chief stepped for ward to the button, by pressing which the power of the motor was developed. The chief of the scientific corps then showed him the exact point upon the scale, which would be indicated when the gun was in it's proper position, and the piece was then moved upon its bear ngs so as to approximate as nearly as possible this direction.
 The bow Of the vessel now rose upon the swell of the sea, and the instant that the index upon the scale reached the de- sired point, the director-in-chieft touched the button. y.
 . There was no report, no smoke, no visible sign that the motor had left the cannon; but at that instant there appeared, to those who were on the lookout. from fort about 8 mile away, a vast aperture in the waters of the bay. which was variously described as from 100 yards to 500 yards in diameter. At that same in- stant, in the neighboring headlands and islands far up the shores of the bay, and in every street and building of the city, there was felt sharp shock as if the underlying rocks had been struck by gigantic trip hammer.
 At the same instant the sky above the spot where the motor had descended was darkened by wide spreading cloud. This was formed of that portion of the water of the bay which had been in- stantaneous raised to the height of about a thousand feet. The sudden appear ance of this cloud was even more terri ble than the yawning chasm in the waters of the bay, CT the startling shock, but it did not remain long in view. It had no sooner reached it's highest eleva- tion than it began to descend. There was strong sea breeze blowing, and in its descent this vast mass of water was fn1pelled toward the land.
 It came down, not as rain, but as the waters of vast cataract, as though a mountain lake, by an earthquake shock, had been precipitated in body upon a valley. Only one edge of it reached the land, and here the seething flood tore away earth, trees and rocks, leaving be- hind it great chasms and gullies as it descended to the sea.
 The bay itself, into which this vast body of the water fell, became scene of surging madness. The towering walls of water which had stood up all around the suddenly created aperture hurled themselves back into the abyss, and down into the great chasm at the bottom of the bay, which had been made when the motor sent it's shock along the great rock beds. Down upon, and into, this roar ing, boiling tumult fell the tremendous cataract from above, and the harbor be- came one wild expanse of leaping, mad dened waves, hissing their whirling spray high into the air.
 During these few terrific moments other things happened which passed un- noticed in the general consternation. l All along the shores of the bay and in front of the city the waters seemed to be sucked away, slowly returning as the sea forced them to their level, and at many points up and down the harbor there were submarine detonations and upheavals of the water.
 These were caused by the explosion, by concussion of every torpedo and subma- rine battery in the harbor; and it was with this object in view that the instan- taneous motor bomb had been shot into the mouth of the bay.
 The effects of the discharge of the mo- tor bomb astonished and even startled those on board the repellers and the | the crabs. At the instant of touching the button hydraulic shock was felt on Repeler No. i. This was supposed to be occasioned by the discharge of the mo-
