It was too dark to see more than an inch in front of one's nose, but Hurst could feel, and rapidly ran his fingers over the form of a man supported on the wreckage to which he and his companions were clinging. Was that wreckage the remains of a boat? Undoubtedly no. Then what was it? Both Hawkins and Hurst endeavoured to elucidate what had become a mystery. They ran their hands far and wide over spars and timber. They stretched as far as they were able, while Dicky Hamshaw did likewise, puzzled beyond expression by the strangeness of his immediate surroundings. And then that far-away cry again fell on his ear. "Silence, men," he commanded, in his most peremptory manner. "Now, give 'em a call--all together!" The bellow which the half-submerged members of the crew sent out must have penetrated some considerable distance. They waited for an answering cry, and then were more completely bewildered. For of a sudden the darkness overhead was split in twain by a beam of brilliant light, which shot from a point far above them, a point so brilliant that they dared not gaze at it. A moment before they were struggling in the water surrounded by the densest darkness. Now, they and a huge circle about them were brilliantly illuminated, showing seven forlorn figures bobbing in the ocean about a mass of wreckage of curious formation secured to which was the body of a man more forlorn than themselves. Dicky Hamshaw wondered whether he were dreaming. He stretched out a hand and pulled at the sleeve of that unconscious figure. And then he gazed aloft, wondering from whence that light came, who could have cast it upon them, and what manner of ship it was that floated there, invisible and stationary yet a ship for all that; for a man or men were aboard it. Cries had come from that direction, while their own shouts had been followed by the sudden jet of light which now played about them. Was he dreaming indeed? or could that actually be the figure of a man descending through the very centre of the beam towards them, descending at a speed which made him giddy, treading steps which there was no seeing? "Jingo!" he gasped. "This is getting too hot for anything. Why--why, the man's on a rope. Now, what in the dickens supports him?"
