Behind the three, at a distance of a few hundred yards, was the building—or rather group of buildings—which formed their home. These were built bungalow-fashion, save as to one part—the observatory—which rose above the rest, with detached dwelling-places for their attendants close by. Inland, the ground fell away, and there was on one side a winding road down to the shore. On the other side, the ground rose again towards higher ridges in the centre of the island. The old man remained for some minutes gazing fixedly upwards; the two young fellows, very much surprised, and—if the truth be told—a little awed by his demeanour, remained also motionless, gazing alternately at him and at each other. Suddenly the sage uttered a sort of cry—an exclamation so strange, so thrilling, that his companions were startled, and stared anxiously about, seeking for an explanation. Then they saw him raise an arm and point to the sky, and, following the direction thus indicated, they both started and stood and gazed fixedly as though spell-bound. ’Look!’ exclaimed Jack. ’It is a meteor!’ And that was all that was said—all, indeed, there was time for. There was no time for questions, for comments, for anything, in fact, save a great gasp of astonishment, and scarcely even for that. Careering towards them through the upper air, at what seemed lightning speed, was something which left a long, luminous trail behind it. Rays and flashes of light of different colours burst from it in its course, darting out in all directions. A low, rushing sound became audible, which quickly increased in volume until it became a terrific, deafening, overwhelming roar. There was a sudden disturbance in the air, as of the approach of a whirlwind, and a crackling noise as of the discharge of fireworks. Then something seemed to shoot past them into the sea, the ’wind’ from it almost brushing them aside like that caused by a shell fired from some colossal cannon. From the sea came a mighty crash as of a loud explosion, while columns of water and clouds of vapour rose into the air. The water came right over the top of the cliff, drenching the amazed spectators, and almost sweeping one—it was Jack—off his feet. Hardly had the spray cleared away when there was another commotion in the water. The sea, boiling and chafing, seemed to rise up into a pyramid, and from it a huge dark mass shot up into the air, dropping back into the sea again with a plunge only a little less violent than that which had accompanied its first fall. For a brief space it was lost to view, and then it reappeared, shooting again high into the air, as might a gigantic whale throwing itself out of the sea in sport or an endeavour to escape some terrible marine foe. These mad leaps and plunges were repeated again and again, becoming each time less in height and violence, until at last they ceased.
