“Not that we have found as yet, boy, but they must have left some wounded men, or sick, belonging to the army or the enemy. If they’re fighting their way, as is most likely, we may be sure that a good many men have fallen.”

“Yes, that’s reasonable enough, Serge, but we have seen no signs of one.”

“Not one,” said the old soldier. “So as there have been no traces, we must go by guesswork, mustn’t we?”

“Yes, of course,” cried Marcus. “Well, you guessed and I guessed, and I think my guess will be the better one.”

“I know you do; but I don’t, boy.”

“Why?”

“Because there’s no reason in yours and there is in mine.”

“I can’t see that,” said Marcus, stubbornly. “Show me how your way can be better than mine.”

“That’s soon done, boy,” said Serge. “Caius Julius will have a big army with him, won’t he?”

“Yes, of course; a very large one.”
