Now, where there is a definite object to steer by, or a compass to guide one, and a decent rudder, even an inexperienced hand can manage to come somewhere near the point that he aims at. But take a boat like Tom's, and a rude and suddenly extemporized sail, with no other rudder than a bit of board, with no compass, and a surrounding of thick fog, and it would puzzle even an experienced sailor to guide himself aright. Tom soon suspected that his course was rather a wild one; his board in particular became quite unmanageable, and he was fatigued with trying to hold it in the water. So he threw it aside, and boldly trusted to his sail alone. The boat seemed to him to be making very respectable progress. The wind was fresh, and the sea only moderate. The little waves beat over the bows, and there was quite a commotion astern. Tom thought he was doing very well, and heading as near as possible towards the Petitcodiac. Besides, in his excitement at being thus saved from mere blind drifting, he did not much care where he went, for he felt assured that he was now on the way out of his difficulties. In an hour or two after leaving the ledge it grew quite dark, and Tom saw that it would be necessary to prepare for the night. His preparations were simple, consisting in eating a half dozen biscuit. He now began to feel a little thirsty, but manfully struggled against this feeling. Gradually the darkness grew deeper, until at last it assumed the intense character of the preceding night. But still Tom sat up, and the boat went on. The wind did not slacken, nor did the boat's progress cease. Hours passed by in this way. As to the tides, Tom could not tell now very well whether they were rising or falling, and, in fact, he was quite indifferent, being satisfied fully with his progress. As long as the wind distended his sail, and bore the boat onward, he cared not whether the tide favored or opposed. Hours passed, but such was Tom's excitement that he still bore up, and thought nothing of rest or of sleep. His attention was needed, too, and so he kept wide awake, and his ears were ever on the stretch to hear the slightest sound. But at last the intense excitement and the long fatigue began to overpower him. Still he struggled against his weakness, and still he watched and listened. Hours passed on, and the wind never ceased to fill the sail, and the boat never ceased to go onward in a course of which Tom could have no idea. It was a course totally different from the one which be intended--a course which depended on the chance of the wind; and one, too, which was varied by the sweep of the tide as it rose or fell; but the course, such as it was, continued on, and Tom watched and waited until, at last, from sheer exhaustion, he fell sound asleep.
