A moment of breathless astonishment succeeded the accomplishment of this nice manoeuvre, but there was no time for the usual expressions of surprise. The stranger still held the trumpet, and continued to lift his voice amid the howlings of the blast, whenever prudence or skill required any change in the management of the ship. For an hour longer there was a fearful struggle for their preservation, the channel becoming at each step more complicated, and the shoals thickening around the mariners on every side. The lead was cast rapidly, and the quick eye of the pilot seemed to pierce the darkness with a keenness of vision that exceeded human power. It was apparent to all in the vessel that they were under the guidance of one who understood the navigation thoroughly, and their exertions kept pace with their reviving confidence. Again and again the frigate appeared to be rushing blindly on shoals where the sea was covered with foam, and where destruction would have been as sudden as it was certain, when the clear voice of the stranger was heard warning them of the danger, and inciting them to their duty. The vessel was implicitly yielded to his government; and during those anxious moments when she was dashing the waters aside, throwing the spray over her enormous yards, each ear would listen eagerly for those sounds that had obtained a command over the crew that can only be acquired, under such circumstances, by great steadiness and consummate skill. The ship was recovering from the inaction of changing her course, in one of those critical tacks that she had made so often, when the pilot, for the first time, addressed the commander of the frigate, who still continued to superintend the all-important duty of the leadsman. “Now is the pinch,” he said, “and if the ship behaves well, we are safe--but if otherwise, all we have yet done will be useless.” The veteran seaman whom he addressed left the chains at this portentous notice, and calling to his first lieutenant, required of the stranger an explanation of his warning. “See you yon light on the southern headland?” returned the pilot; “you may know it from the star near it?--by its sinking, at times, in the ocean. Now observe the hummock, a little north of it, looking like a shadow in the horizon--'tis a hill far inland. If we keep that light open from the hill, we shall do well--but if not, we surely go to pieces.” “Let us tack again,” exclaimed the lieutenant. The pilot shook his head, as he replied: “There is no more tacking or box-hauling to be done tonight. We have barely room to pass out of the shoals on this course; and if we can weather the 'Devil's Grip,' we clear their outermost point--but if not, as I said before, there is but an alternative.” “If we had beaten out the way we entered,” exclaimed Griffith, “we should have done well.”
