Night drew on. With the setting of the sun powerful search-lights swept the Golden Horn to the Bosphorus, while the now alert Turkish gunners stood by their guns, ready at the first sight of a periscope to send the Giaours to Eblis, for there was a strong suspicion that the daring British craft would still be lurking in the vicinity in order to attempt another act of destruction. "Time, I fancy," declared Huxtable, as the hands of the clock on the wall of the conning-tower pointed to the hour of midnight. Officers and men heaved a sigh of relief. Anything seemed better than lying motionless on the bed of the channel. It was inexpedient to start the motors. The submarine must be raised under the influence of her reserve of buoyancy until there was no chance of her propeller blades being snapped off by contact with the shoal. The periscope showed nothing beyond a confusing display of search-lights. Huxtable took the craft up still more until her conning-tower was awash. To his surprise he found that the submarine was drifting almost across the bows of a large coal-hulk, which was moored about two hundred yards from shore. A similar type of vessel lay fifty yards from, and abreast of, the hulk. Both craft, owing to their being practically denuded of coal--a commodity of which the Turks were greatly in need--towered high out of the water. There were no signs of ship-keepers. Darkness and solitude seemed to be in sole possession. In a flash Huxtable realized that, if he could make fast alongside one of the hulks, the submarine would be in comparative shelter from the piercing rays of the search-lights, since the second hulk would screen his craft from the direct play of their beams. It was a desperate move, but like most desperate operations its audacity almost promised success. With a slight, almost imperceptible shock, one of the protective girders encircling the submarine engaged the mooring chain of the hulk. Round swung the submarine, and before she could slip from the embrace of the heavy chain two of her crew, emerging through the fore-hatch, deftly bent a wire hawser to one of the links, and, cautiously checking the boat's way, succeeded in bringing her alongside the coaling craft. No hail came from this vessel. The hulk was seemingly deserted. Having no supplies on board, the Turkish authorities did not see the necessity of keeping watchmen there, or else the ship-keepers had taken a chance of going ashore. Huxtable's command was not a second too soon in bringing up alongside, for a search-light playing full upon the hulk silhouetted her outlines and threw a deep shadow athwart the submarine. Lying at full length upon the wet deck, the two seamen awaited the order to cast off should necessity arise, while the Lieutenant-Commander, thrusting his head and shoulders through the conning-tower hatchway, made a deliberate survey of the limited expanse that met his gaze.
