The news from little Bermuda was submerged, unheeded, in this greater catastrophe. But on the night of May 17th when the American warships arrived off Hamilton, the Paget invaders were gone. The menace in Bermuda was over; it was the great New York City which was menaced now. The apparitions which had advanced from the south were suddenly joined by a much more numerous army. On the night of May 19th it had reached New York. Two or three thousand glowing white shapes were apparent, with yet other thousands perhaps hovering just beyond visibility. They made no attack. They stood encamped on the borderland of the Unknown realm to which they belonged. Busy with their preparations for battle and watching the stricken city to which already mere terror had brought the horror of disease and death. It seemed now that this Fourth Dimension terrain co-existing within in the space of New York City, must be a tumbled, mountainous region of crags and spires, and yawning pits, ravines and valley depths. Jagged and precipitous indeed, for there were apparitions encamped in the air above Manhattan and harbor--higher in altitude than the Chrysler or the Empire State towers. Other wraiths showed in a dozen places lower down--some within the city buildings themselves. And yet others were below ground, within the river waters, or grouped seemingly a hundred feet beneath the street levels. Fantastic army of wraiths! In the daylight they almost faded, but at night they glowed clearly. Busy assembling their weapons of war. Vanishing and reappearing at different points. Climbing or descending the steep cliffs and crags of their terrain to new points of vantage; and every hour with their numbers augmenting. And all so silent! So grimly purposeful, and yet so ghastly silent! It was near midnight of May 19th when the wraiths began materializing and the attack upon New York City began! CHAPTER VII _The Invisible World_ Tako showed us how to operate the transition mechanism. The little banana grove on the Bermuda hilltop began fading. There was a momentary shock; a reeling of my head; a sudden sense of vibration within me. And then a feeling of lightness, weightlessness; and freedom, as though all my earthly life I had been shackled, but now was free. The thing was at first terrifying, gruesome; but in a moment those feelings passed and the weightless freedom brought an exuberance of spirit. Don and I were sitting with Jane between us, and the figure of Tako fronting us. I recall that we clung together, terrified. I closed my eyes when the first shock came, but opened them again to find my head steadying. Surprising vista! I had vaguely fancied that Tako, Jane and Don would be sitting here dissolving into apparitions. But my hands on Jane's arm felt it as solid as before. I stared into her face. It was frightened, white and set, but smiling at me. "You all right, Bob? It's not so difficult, is it?"
