The clicking and rasping both ceased after a while, and then another sound reached me. This resembled the rushing of a mighty wind, but I knew it was not that. I knew it was the "sough" of the sea against the sides of the vessel. It produced a delightful impression upon my mind, for it told me that _the big ship was in motion_! "Hurrah! we are off!" CHAPTER TWENTY. SEA-SICK. The continued motion of the vessel, and the seething sound of the water, which I could hear very plainly, convinced me that we had parted from the quay, and were moving onward. I felt completely happy; there was no longer any fear of my being taken back to the farm. I was now fairly launched upon salt-water, and in twenty-four hours would be out on the wide Atlantic--far from land, and in no danger either of being pursued or sent back. I was in ecstasies of delight at the success of my plan. I thought it rather strange, their starting _in the night_--for it was still quite dark--but I presumed they had a pilot who knew all the channels of the bay, and who could take them into the open water just as well by night as by day. I was still somewhat puzzled to account for the extreme length of the night--that was altogether mysterious--and I began to think that I must have slept during the whole of a day, and was awake for two nights instead of one. Either that, or some of it must have been a dream. However, I was too much joyed at the circumstance of our having started, to speculate upon the strangeness of the hour. It mattered not to me whether we had set sail by night or by day, so long as we got safely out into the great ocean; and I laid myself down again to wait until the time should arrive, when I might safely show myself on deck. I was very impatient for the arrival of that crisis, and for two special reasons. One was, that I had grown very thirsty, and longed for a drink. The cheese and dry crackers had helped to make me so thirsty. I was not hungry, for part of the provision was still left, but I would gladly have exchanged it for a cup of water. The other reason why I wanted to get out of my hiding-place was, that my bones had become very sore from lying so long on the hard plank, and also from the cramped attitude I was compelled to assume, on account of the want of space. So full of pain did my joints feel, that I could hardly turn myself about; and I felt even worse when I continued to lie still. This also strengthened my belief that I must have slept during the whole of a day, for a single night upon the naked timbers could hardly have tired me so much. What with the thirst, therefore, and the soreness of my bones, I kept fidgeting and wriggling about for several hours, without intermission. For these two reasons I was very impatient to crawl forth from my narrow quarters, and set my foot upon deck; but for other reasons I deemed it prudent to endure both the thirst and the aching, and remain where I was for some time longer.
