"She can take it up elsewhere."

But though they had expected to have difficulty in persuading her, they found that Madame Martin was already making plans to go.

"The wounded are to be taken to Tours in great numbers," she told them. "They will need nurses there, and I shall go. Henri, will you and Francois come with me?"

"We cannot," said Henri. "There is work for us to do. You would want me to do my share?"

"Of course I do!" she said, her eyes filling with tears. "And so speaks every mother in France to-day! Stay, then, and serve your land in whatever way you can, for France needs even the boys now. Remember, Henri, that somewhere your mother is serving too, and she expects her son to do his whole duty. More, she knows he will do it." And her face glowed with pride in her son as she clasped his hand in her own.

"I will remember," said Henri.

Then they went to their room, laid away their newly acquired uniforms of Boy Scouts, and, keeping not even their new badges of which they had been so proud, especially Henri, dressed in their ordinary clothes.

"Let's start on bicycles, anyhow," proposed Frank. "We may not be able to stick to them, but we can save a lot of time on our way to Le Cateau. That's where we shall go first, isn't it?"

"Yes. We had better start for there. You're right about the bicycles, too. Even if we lose them, that does not matter so much," said Harry.

"And, Harry, we've got to pretend to be pretty stupid, if we are caught. You mustn't act as if you knew too much. Don't let the Germans see how you really feel about them. Pretend to be terribly frightened, even if you're not," instructed Frank.
