At this the older girl walked across the room and stood for a moment by the one window which looked out upon the woods. If she had wished to reply at once it would have been impossible. For at this instant a tremendous shell exploded at no great distance away, shaking the little house and making a noise that was almost deafening.

Yet neither girl mentioned the occurrence to the other.

When it was over Eugenia turned quietly around.

“I expect to remain here if I find I can be more useful. But after all, I may be talking like a foolish old crow croaking over misfortunes that never come. Goodness knows, the French have repelled numbers of attacks before! Even if the Germans have reinforcements they will probably drive them back. I only wanted us to be prepared to meet the worst. But I’m dreadfully sorry if I have frightened you unnecessarily, so perhaps it will be best not to speak of my foolishness to the other girls. Now let’s hurry and be off.”

But Barbara would not be hurried, neither would she be silenced.

She sat down for a moment on the top of a high wooden stool, her feet swinging in the air, looking like a little girl of fourteen, in spite of the fact that she wore her nurse’s cap and uniform.

“I think you forget that we are Red Cross nurses,” Barbara argued thoughtfully, talking not so much to her companion as to herself. “So even if the Germans do take the trenches in this vicinity and occupy the French country, we shall be perfectly safe. Our Red Cross badges are our protection.”

The older girl put her arm across the younger one’s shoulder, not affectionately, but protectingly.

“More than probably you are right, Barbara. But somehow I’d feel happier not to have you girls too near here. Many of the houses may be burned and the German soldiers excited by their triumph. It would be the same in any conquered country, I have no doubt. I do not mean that I think the German soldiers more brutal than other men under like conditions. But remember, we have been living in an enemy’s country and nursing their soldiers and even if ninety-nine of the soldiers were considerate, one might be rough and unkind. Of course, I can’t make you promise to do what I ask against your will, but if the danger comes will you remember what I have said and try and be prudent?”

And Barbara nodded as she got off her stool.
