The tube itself, which is of iron, enormously thick, has glass sides, also of huge thickness, running parallel with the windows of the car so that the view is unobstructed. The sensations awakened, therefore, both by the novelty of the situation and by the wonders we passed in review, combined to make the journey thrillingly exciting. We were swept, for instance, past armies of fishes, beautiful to behold in such masses, shimmering in their opalescent armor as they rose above, or sank out of sight into the depths below. The sudden depressions and abrupt elevations of the sea-level made the scenery full of diversity. There was a great abundance of color, with the vivid crimson of the coralline plants and the delicate pinks and yellows of the many varieties of the sub-marine flora. It seemed at times as if we were caught in a liquid cloud of amber, or were to be enmeshed in a grove of giant sea-weeds. Beyond all else, however, in point of interest, was the spectacle of the wholesale cannibalism going on among the finny tribes, a cannibalism which still exists, in spite of the persistent and unwearying exertions of the numerous Societies for the Prevention of Cruelty among Cetacea and Crustacea. We passed any number of small boats darting in and out among the porpoises, dolphins and smaller fish, delivering supplies (of proper Christian food) and punishing offenders. A sub-marine missionary, who chanced to sit next to me, told me that of all vertebrate or invertebrate animals, the fish is the least amenable to reformatory discipline; fishes appear to have been born, he went on to say, without the most rudimentary form of the moral instinct, and, curiously enough, only flourish in proportion as they are allowed to act out their original degenerate nature. He also confessed privately to me, that after some twenty-five years active work among them, the results of his labors were most discouraging. Since, however, the Buddhistic doctrine of metempsychosis has come to be so universally accepted, and as each one of these poor creatures is in reality a soul in embryo, it behoves mankind to do all that lies in its power to elevate all tribes and species. As you may well imagine, my dear Hannevig, with such spectacles and speculations to enliven the journey, I found it all too short. Its shortness was, in truth, the only drawback to my complete enjoyment. The wonders of the journey, I found, were, however, only a fitting prelude to the surprises that awaited me on my arrival. I leave an account of both these surprises and of my first impressions of the great city until my next letter, as this one, I find, has already grown to the proportions of an ancient epistle. I am, my dear Hannevig, Your life-long friend and comrade, WOLFGANG. II. DEAR HANNEVIG:
