"That's just it," answered the man. "We can't see half as far as we did an hour ago. Seems like as if there was a thick sea-fog coming on. I was thinking only this morning what a time we had been without one. That's a fog-bank and no mistake, and drifting right down upon us, too. I must go and see to the horn. We must start that if it comes over us; else your father might never find his way back--to say nothing of the ships running aground here. You'll hear her voice, and no mistake, little master, before another hour is over; and a mighty queer voice it is, I can tell you. You'll not forget it easy, once you've heard it!" Pat was immensely interested. He followed Jim up into the upper room, and went out upon the gallery to watch the great fog-bank creep slowly down upon them. The sun was so bright and clear that it seemed impossible that that slowly moving white mass should ever obscure it; but soon a few little light vapour wreaths drifted up against the rocks, and very quickly the sun looked dull and red, and little by little the sky and the sea seemed all to be blotted out, and Pat could not tell which way he was looking, nor where the land lay. He seemed to be up alone in some high place, floating in mid-air, in a world of vapour. He would have been frightened if he had not heard Jim moving about close at hand. And then, all in a moment, a most fearful and extraordinary noise just above his head made Pat clap his hands to his ears, as though his head would come off with the vibration if he did not. He knew what it was. _She_ had been awakened from sleep, and was lifting up that great voice of hers, as he had heard she could do when it was wanted; and in great amazement, Pat ran indoors to see how she did it. He felt that such a wonderful creature as this had surely never lived before! [Illustration] [Illustration] CHAPTER IV _LONE ROCK IN FOG AND STORM_
