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!
[CHAPTER IV]
LONE ROCK IN FOG AND STORM
But strange and fascinating as was the voice of the great She, Pat could not be quite happy till his father and his mother had got back safe to the rock again. He could not imagine how they could find their way in all the thick wreaths of darkness which shut the Lone Rock in; but Jim told him that very likely it was quite clear a little way off, and that the noise of the horn, which sounded every three minutes, would guide his father safely to the right place. The sea was quite smooth and still; he could approach without any trouble. Jim knew that Nat would not be easy away from his post, more especially now that this fog had come on, which would entail extra care and extra work. There was a mechanical apparatus worked by steam, which could keep the horn blowing at intervals for a certain number of hours; but that required attention too, and for the present, Jim preferred to work it by the bellows, remaining up aloft, and bidding Pat keep watch for the boat below, if he liked, but to be very careful not to lose his footing on the rocks, as there would be nobody to come to his help.
Pat was not afraid of that now. He always ran about barefoot, and was as sure of foot as a goat by this time.
