Suddenly, however, the darkness was dispelled by the vivid flashes of lightning, which, darting from the low hanging clouds, circled about their heads, throwing a lurid glare on the countenances of all on deck. Once more all was dark; then again the forked lightning burst forth hissing and crackling through the air, leaping along the waves and playing round the quivering masts. Now the big ship plunged into the trough of the sea with a force which made it seem as if she was never going to rise again; but up the next watery height she climbed, and when she got to the top, she stopped as if to look about her, while the lightning flashed brighter than ever; and then, rolling and pitching, and cutting numerous other antics, she lifted up her stern as if she was going to give a vicious fling out with her heels, and downwards she plunged into the dark obscurity, amid the high foam-topped seas, which hissed and roared high above her bulwarks. Her crew walked her deck with but little anxiety, although they saw that the gale was likely to increase into a hurricane; for they had long served together, they knew what each other was made of, and they had confidence in their officers and in the stout ship they manned. The watch below had hitherto remained in their hammocks, and most of them, in spite of the gale, slept as soundly as ever. What cared they that the ship was roiling and tumbling about? They knew that she was watertight and strong, that she had plenty of sea-room, and that they would be roused up quickly enough if they were wanted. There was one person, however, who did not sleep soundly--that was her Captain, Josiah Penrose. He could not forget that he had the lives of some eight hundred beings committed to his charge, and he knew well that, even on board a stout ship with plenty of sea-room, an accident might occur which would require his immediate presence on deck. He was therefore sitting up in his cabin, holding on as best he could, and attempting to read--a task under all circumstances, considering that he had lost an eye, and was not a very bright scholar, more difficult of accomplishment than may be supposed. He had lost an arm, too, which made it difficult for him to hold a book; besides, his book was large, and the printing was not over clear, a fault common in those days; and the paper was a good deal stained and injured from the effects of damp and hot climates. He was aroused from his studies by a signal at the door, and the entrance of one of the quartermasters. "What is it, Pringle?" asked the Captain, looking up. "Why, sir, Molly Freeborn is taken very bad, and the doctor says that he thought you would like to know," was the answer. "He doesn't think as how she'll get over it. Maybe, sir, you'd wish to see the poor woman?" "Certainly, yes; I'll go below and see her," answered the Captain in a kind tone. "Poor Molly! But where is her husband--where is Freeborn? It will be a great blow to him."
