He knew at once that the army was advancing.

Before him and behind him he heard all the noises of the march, the beat of horses' hoofs, the grinding of wheels, the clanking of cannon, the cracking of whips and the sounds of many voices.
He was wonderfully comfortable where he lay and he had the satisfaction and pride of much duty done.

He felt that he was entitled to rest, and, turning on his side, he went to sleep again.

After another unknown time his second awakening came and he remained awake.
He quietly slipped out at the tail of the wagon, and stood for a few moments, dazzled by the blazing sunlight.

Then a loud, cheery voice called out: "Well, if it isn't our own Lucky Dick come back again, safe and well to the people to whom he belongs!" "If z equals Dick and y equals his presence then we have z plus y, as Dick is certainly present," called out another voice not quite so loud, but equally cheery.
