With the same wonder with which in later life we begin to watch the marvellous workings of the functions of our bodies I entered on my new investigation. As we approached Oolorefa it seemed to me that we had made a mistake and come to the wrong building; for it rang with the most entrancing music and I thought that it must be the cathedral of the island. It had one vast central dome surrounded by countless cupolas, and as we skirted the edifice I heard underneath each of these smaller roofs sweet melodies sounding too low to be heard beyond its partition walls and almost drowned in the thunderous diapason of the central dome. These I took for chapels and fanes subsidiary to the great temple, round which they clustered. We entered and I was amazed to find under what I had thought to be the temple of the island a great mansion, but dwarfed by the height and size of the temple roof. The fence enclosing it had just been shaken to dust by their new electric process for the atomising of irelium. What was to be done with the new structure? It was walled in by the giant cupola, and could not possibly be removed. The thought was beating about in my mind, but ceased before a sudden crash; I looked up and there, one complete and evenly cut quadrant of the dome had vanished, and the bright sun shone in undimmed by any medium. I again noticed something going on around us. Great flanks like the sides of a ship were fitted to the bottom of the new building, and along them underneath were adjusted huge floats. Wings were then attached to either side, and a strong wing-engine was placed in the body and two rudder-engines in the after-part of the raft. They were rapidly charged with electricity, the floats were exhausted of their heavier air, and up rose the whole structure through the huge aperture in the dome; and I could see its pilots guide it this way and that through the air to fit the unequal and varying wind that blew, till at last it disappeared round a shoulder of Lilaroma. I had run out of Oolorefa to watch the flight of the great mansion on its aërial raft, and when it went out of sight I returned, reflecting with a sigh of relief that this explained the magic growth of the house in which I lived; the additions had arrived and been fixed and adapted to the purposes of human habitation while I was sleeping or absent on my daily pursuits.
