"All present and aboard, sir," cried Hawkins, using that formula by force of habit. "All clinging tight, sir."

"But to what? And there's that shout again. This is getting beyond me," declared the youthful Dicky, not in despondent tones it must be declared, for never was there a lighter-hearted nor more courageous individual. But in a manner which showed that the speaker was sorely puzzled. No wonder, too, for that elusive call sounded now as if it came from the sky again. It made the bulky Hurst actually tremble. He was shivering already, for the water was cold, and this sudden immersion was no joke under the circumstances. But now that call, three times repeated, sent a cold shiver down his back, as if someone had suddenly added a huge block of ice to the water.

"I'm jiggered," he stuttered, his strong teeth chattering. "From away up aloft. Why, there's a man here, sir, tied up to this here wreckage."

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?"

What indeed? Not one of the men clinging to that strange wreckage in the water illuminated so wonderfully could guess to what class of vessel that rope could be attached. For nothing was visible aloft save that one penetrating eye, that brilliant orb which shot down upon them its dazzling beams. Hurst shivered yet again. Even Mr. Midshipman Hamshaw was decidedly disconcerted and nonplussed by the uncanniness of the situation. For that man, dangling from a rope, turning like a spider hanging by a single thread, and swaying from side to side as the wind caught him, appeared to be supported by nothing in particular. And yet he was descending towards them at an amazing rate, and that too with no effort on his own part. Someone above must be paying out the rope to which he was attached. But who? Where was the spot from which he had started? What sort of vessel hovered aloft?

"I'm hanged," ventured Dicky.

"It's just the queerest thing as ever I seed, sir," admitted Hawkins. "But there's one thing I'm sure of. This here wreckage is what's left of a waterplane. See there—one of the floats is on the top of the water. There's generally two, so one can guess that the other's foundered, and if it wasn't for this here one the whole affair would have sunk. It's lucky for us and lucky for the man here. French, sir."
