He looked at that small fragment of food with longing eyes, and the longer he looked at it the more tempting did it seem, and the more irresistible did the temptation grow. At last he thought that it would be better to strengthen himself now after his long journey, and secure a good night’s rest. On the morrow he could look out for food and get something to eat--somewhere, he knew not where--somehow, he knew not how. This thought appeased his cautious scruples. He hesitated no longer, but ate what remained of the sandwich. And so his last particle of food was gone. But he gave no thought to this. He was too tired, and worn out with exhaustion he lay down and fell asleep.

To his disappointment he found those prospects not at all changed for the better. Overhead he saw the rolling smoke clouds, which now were gloomier and denser than before, and still nearer the earth. The atmosphere caught from them a very perceptible odor, which showed the character of the clouds above, and was pungent enough to create some degree of irritation in the nose and throat. The spot where he was appeared to be somewhat more open than usual, and in some directions he could look over a space several rods in extent. In this direction the smoke haze was very apparent. He felt both hungry and thirsty. But he had nothing whatever to eat, and knew it. He had eaten his last mouthful the evening before, and there was nothing whatever left now to satisfy the demands of his appetite. But for the present his thirst was stronger than his hunger; and so parched was his throat, and so painful was his craving for water, that he at once started up, and set out in search of some.
