Altogether, Gerald decided, a man to be loved and trusted, or hated and dreaded, according to whether he were a friend or an enemy; a born leader of men, a being of indescribable majesty and dignity in general appearance, yet possessed of a singular simplicity and charm of manner.

As to the dress of this attractive stranger, it is more difficult to describe, for the reason that Gerald perceived at once that the material was unlike anything he had ever seen before. There was a long tunic, with a belt of gold, and a very picturesque head-dress not unlike that in vogue in England in the days of Henry the Eighth; while the arms and legs were encased in garments which fitted closely, showing the figure clearly. That much was plainly to be seen. But what the dress consisted of was a puzzle, for it seemed to have a sheen of its own, a sort of shimmer which did not appear to be altogether reflected light. There were several little ornaments here and there, such as buckles on the shoes and another on the shoulder; but the chief embellishment was a large star upon the breast, which flashed and sparkled and seemed to be worked in diamonds.

Behind this regal figure were three or four others, who stood respectfully in the background, evidently in attendance upon him. Suddenly, while Gerald still gazed in ever-increasing wonder upon the unexpected scene, the stranger reeled as though suffering from an attack of faintness. He put his hand to his breast, and appeared to be panting for breath. Blood showed upon his face and ran off on to his dress, and the next moment he staggered and fell off the platform into the sea.

Gerald did not hesitate. He guessed that the man must have fainted; he knew that the spot where he had fallen in was outside the ledge on which the supposed 'meteorite' was resting; that it was of unfathomable depth, and that, therefore, his danger was imminent and deadly. Throwing off his jacket, therefore, Gerald dived into the water, and that with such promptitude that the second splash followed closely upon the first.

But the stranger had fallen from a height, and the impetus carried him down faster than that gained by Gerald's dive from the boat, so that he failed to grasp the fainting stranger, and was compelled to swim downwards in the hope of finding him.

Down, down, ever down, he went, clawing at the water with fierce energy, and battling his way with feverish determination, knowing that, with those awful depths beneath him, the stranger's one and only chance of life lay in his—Gerald's—overtaking and gripping him.

It was a long and terrible struggle—long, that is, comparatively—and the pressure of the water became oppressive, when, at last, just as the plucky diver felt he must give up and return to the surface, his hand touched something. His fingers closed at once upon it, and he felt that he had secured his prize.

A few seconds later he had regained the surface, and found himself, panting, and all but exhausted, close to the boat, from which Clinch was watching for him. The sailor was aiding his search upon the waters around by throwing on them the rays from the dark lantern, which had been lighted and placed ready to hand in the stern.

A stroke or two brought the boat close enough for Gerald to get a hold upon it with one arm, while with the other he supported in the water the stranger's insensible form.

'Wait, sir; wait an' get yer breath!' counselled the old sailor. 'Take it easy, Mr Gerald! I 'll hold on to t' other chap, never fear! You let go on 'im, an' get yer breath!'
