Dr. Milton’s lips tightened. “That’s what we are here for, isn’t it? Oh, I understand what you mean; of course you have no fear for yourself. Let’s think the situation over.”

The young fellow who had charge of the particular ambulance in which Nona and Barbara were acting as nurses was a young Englishman who had volunteered for the service from one of the Manchester automobile factories. He was a skilled and trained workman and believed that in guiding a Red Cross ambulance he was doing more for his country than in actual fighting. But he was as gallant as possible and utterly fearless for his own safety.

The two men were together on the front seat of the car. Nevertheless, when they began talking, as long as the ambulance was no longer in movement, both Barbara and Nona were able to understand the subject of their conversation.

However, neither girl spoke immediately.

Nona Davis turned to gaze at her companion.

But Barbara seemed to have her entire attention engaged in straining her ears to the noise of the bombarding. Now and again there was a faint lull and then the noise broke out with added fury. Sometimes the sound came from one side of the line and sometimes from the other. There could be no disputing the fact, fighting had indeed begun again.

Dr. Milton swung around and looked at Nona.

“Miss Davis,” he began. “I know it is a great deal to ask of you and Miss Meade. We are several miles this side of the hospital and the walk will be a long one; nevertheless, won’t you both attempt it? Of course, you have guessed, just as we have, that trouble has broken out afresh in our neighborhood and if our ambulance goes on much farther we may at any moment be in the midst of it. We are flying the Red Cross flag, but that does not always save us, and couldn’t save us in any case from the bursting of a shell. Yet Martin and I feel we must go on toward the battlefield, as we are needed now more than any other time. We must not take you into such danger, so if you will leave us——”

Nona’s golden brown eyes wore almost an exalted look, they were so free from thought of self.

“But won’t nurses also be more needed?” she asked, although not requiring an answer to so self-evident a question.
