"It was the foresail, sir; it has been blown out of the bolt-ropes," replied Hop, coolly; and he seemed to be incapable of anything like fear. "We have lost the reefed foresail, and that is what makes her roll so much worse than she did five minutes ago." Undoubtedly he was right. The sail had steadied her more than we could have imagined; and now she rolled like a log in a mill-race. The sea struck the side of my state-room as though a rock weighing a ton had been cast against it by some giant of the sea or the storm. I was afraid our house on deck would be carried away by the tempest. On board of a large vessel, the loss of a house on deck was a matter of no serious consequences. It was entirely different with the Sylvania, for the loss of it would open the hold to the entrance of the sea. The deluge of water would put out the fire in the furnaces, disabling the engine. The result must be the loss of the vessel and all on board of her. I trembled when I thought of it. Another mountain billow struck the house a little farther aft. I was not willing to wait for another sea to strike her in what I regarded as her weakest point, and we put the helm down. We must give up our course for the safety of the vessel. The steamer made a terrible plunge as we shifted the helm, but we soon got her across the sea. Now she pitched instead of rolling. I called to the engineer, through the speaking-tube, to give her but about half speed, for it made her labor more heavily to drive her into the seas. I calculated that this rate of speed would keep her about stationary on the water. I soon found that she was falling astern. I directed the engineer to give her more steam. I soon gauged it so that she had headway enough to keep her up to the seas without forcing her through them. A sort of equilibrium was established, which gave her an easier position, though it was by no means an easy one. Her bow rose so that the deck must have been at an angle of forty-five degrees, and then she dived down from the top of a big wave at about the same angle. Our port and starboard, as well as the masthead light were burning, and we had closed in the pilot-house, so that we could see nothing ahead. But I found the steamer was manageable when I had got her head to the sea, and I sent Hop Tossford to call the mate and Buck Lingley. I could not tell what might happen, and I felt that all hands should be on deck. I wondered they had not put in an appearance before. But they were all used to this sort of thing, for we had been through a tempest almost as bad in the Gulf of St. Lawrence, and several milder ones at other times.
