Such merchandise has ever provoked the spirit of adventure in hardy, healthy men, and pearls have claimed the lives of the best among them. The health and figure of the friend who beguiled many an evening were sacrificed to the lustrous gem so prized of women. A model of stalwart manhood of the Viking strain, he died early, worn out with the stress with which he sought the most serene of personal adornments. There may have been some slight exaggeration in the popular belief that he had walked along the bottom of the sea from one end of the Great Barrier Reef to the other, a stretch of over one thousand miles; but that he had accomplished more than that distance in the aggregate of his submarine wanderings may be quite credible. Probably there was no human being who possessed such intimate knowledge of the character of the ocean floor within the living bounds of the Great Barrier; and since he was silent, reserved, and self-contained to all save friends of long standing, was never guilty of boasting, and ever reluctant to tell of his adventures, the world is little the wiser from his work, though at the best time of his life most of his days were spent under water in fairyland-like scenes. It may seem absurd to associate fairyland with the depths of the sea; but the shy explorer of many a coral grove has been heard to say that the scenes fulfilled his ideals of what the realms of the fairies might be like. Pearl-divers are more susceptible to the charms of wayward Fortune than those who have not realised the thrill of expectancy with which a huge goldlip, encrusted with coral and swathed with seaweed, is seized. It may contain a gem worth a king's ransom, or but an animal which, though it may be crossed in love, is not engaging in appearance or in any feature or quality commendable. There is the chance; and it appeals to most rational men. Secretive Fortune lures on, promising the bubble pearl 'and proffering that which satisfieth not, until the stress and perils of the avocation tell on the enthusiast, who finds himself not exuberant as wont; that Fortune has been tricking him; that in the pursuit of pearls Chance is oft repellent; and that the prize which seemed impossible to avoid has eluded the most devoted seekers. It may be that my captain did not seek his pearls with zeal beyond that which is common to the calling the world over; but that his enthusiasm beguiled him into remote and odd parts of the Barrier, that he became familiar with rare scenes (denied to all save submarine adventurers in tropical waters), that he was oft in peril of his life, and that he could pause in the midst of strenuous, nerve-racking work to watch the never-ceasing hostilities of the denizens of the sea, may not be questioned.
