This talk took place upon a headland of a lonely island in the Southern Seas. A tropical moon cast its wondrous radiance over everything around, shimmering upon the water, and causing the whole island to appear as though floating in an ocean of molten silver. There was just wind enough now and then to start the graceful palms waving—cool, refreshing zephyrs that set millions of sparkling ripples in motion on the sea, and sent them dancing merrily shorewards to plash at last upon the golden sands at the foot of the cliff. Gerald Wilton and Jack Lawford were two youths, orphans both, who, after having been brought up and educated in England, found themselves, through a curious series of chances, passing their time upon this island under the guardianship of a former friend of Gerald’s father, named Armeath. The latter was a scientist who had chosen to make this out-of-the-way spot—absolutely uninhabited save for himself and his establishment—his home for a year or two, in order the better to pursue certain abstruse studies to which he was ardently devoted. They were stalwart, well-grown, clean-limbed British youths, these two, with good-looking faces and well-knit frames, fond of hunting, shooting, fishing, and all outdoor sports. At first, therefore, it is needless to say, they had enjoyed the change to this far-off island home, and entered with zest into its free, open life. If limited as to space, there were larger islands near, amongst which they could take an occasional cruise, and where they could go ashore for hunting expeditions. But after nearly a year, even this pleasant life had begun to grow a little monotonous. The two high-spirited youngsters were getting somewhat tired of it, and beginning to long—almost unconsciously—for other and more exciting adventures. Of the two, however, Gerald perhaps was more troubled by these vague, restless feelings than his chum. As his friend had said, Gerald was given at times to fits of dreaming. In appearance he was fairer and a little taller than his companion, with gray eyes which often had in them an abstracted, far-away look. Jack, on the other hand, was almost swarthy of skin, with dark hair, firm lips, and keen, alert eyes, which indicated an active, determined character, and a practical, matter-of-fact temperament.
