This phenomenon promised to afford him a gleam of intelligence upon which to found a correct solution of his course. Tom knew that, in the ordinary course of events, the sun ought to rise in the east and set in the west. If he was going to the north, the sun would rise on his right hand--if to the south, on his left hand. The streaks of light grew more and more distinct, and the clouds having rolled away, he satisfied himself where the sun would appear. Contrary to both wings of his theory, the place was neither on his right nor his left, for it was exactly behind him. But his position might be upon a bend of the railroad whose direction did not correspond with the general course of the road. For half an hour longer, therefore, he pursued his way, carefully noting every curve, until he was fully convinced that his course was nearer west than north. The sun rose precisely as had been laid down in the programme, and precisely where he expected it would rise. It was clear enough that he was not moving to the south; and, satisfied that he was in no danger of stumbling upon Richmond, his courage increased, and he plodded on till he discovered a small village--or what would be called such in Virginia--though it contained only a few houses. As he still wore the uniform of the United States army, he did not deem it prudent to pass through this village; besides, he was terribly perplexed to know what station it could be, and what had become of Fairfax. Though he must have passed through the country before, it did not look natural to him. Leaving the railroad, he took to the fields, intending to pass round the village, or conceal himself in the woods till he could go through it in safety. After walking diligently for so many hours, Tom was reminded that he had a stomach. His rations on the preceding day had not been very bountiful, and he was positively hungry. The organ which had reminded him of its existence was beginning to be imperative in its demands, and a new problem was presented for solution--one which had not before received the attention which it deserved. In the fields and forest he found a few berries; but all he could find made but a slight impression upon the neglected organ. If Tom was a philosopher, in his humble way, he was reasonable enough to admit that a man could not live without eating. At this point, therefore, the question of rations became a serious and solemn problem; and the longer it remained unsolved the more difficult and harassing it became. After he had rested all the forenoon in a secluded spot, without interruption from man or beast, he decided to settle this question of rations once for all. If impudence had enabled him to pass a line of rebel sentries, it ought to furnish him with a dinner. Leaving his hiding place, he walked till he discovered a small house, at which he determined to apply for something to eat. CHAPTER XVII. DINNER AND DANGER.
