What this extraordinary message meant could not be imagined by any officer of the garrison. If the people on board the ships were taking advantage of the earthquake, and supposed that they could induce British soldiers to believe that it had been caused by one of their bombs, then were they idiots indeed. They would fire their second shot at Fort Pilcher! This was impossible, for they had not yet fired their first shot. These Syndicate people were evidently very tricky, and the defenders of the port must therefore be very cautious. Fort Pilcher was a very large and unfinished fortification, on a bluff on the opposite side of the harbour. Work had been discontinued on it as soon as the Syndicate's vessels had appeared off the port, for it was not desired to expose the builders and workmen to a possible bombardment. The place was now, therefore, almost deserted; but after the receipt of the Syndicate's message, the commandant feared that the enemy might throw an ordinary shell into the unfinished works, and he sent a boat across the bay to order away any workmen or others who might be lingering about the place. A little after two o'clock P.M., an instantaneous motor-bomb was discharged from Repeller No. 1 into Fort Pilcher. It was set to act five seconds after impact with the object aimed at. It struck in a central portion of the unfinished fort, and having described a high curve in the air, descended not only with its own motive power, but with the force of gravitation, and penetrated deep into the earth. Five seconds later a vast brown cloud appeared on the Fort Pilcher promontory. This cloud was nearly spherical in form, with an apparent diameter of about a thousand yards. At the same instant a shock similar to that accompanying the first motor-bomb was felt in the city and surrounding country; but this was not so severe as the other, for the second bomb did not exert its force upon the underlying rocks of the region as the first one had done. The great brown cloud quickly began to lose its spherical form, part of it descending heavily to the earth, and part floating away in vast dust-clouds borne inland by the breeze, settling downward as they moved, and depositing on land, water, ships, houses, domes, and trees an almost impalpable powder. When the cloud had cleared away there were no fortifications, and the bluff on which they had stood had disappeared. Part of this bluff had floated away on the wind, and part of it lay piled in great heaps of sand on the spot where its rocks were to have upheld a fort.
