“Oh, I would like to be a Joan of Arc,” interposed Grace at this point, her blue eyes suddenly afire. “I think it would be great to ride in front of an army on a white charger. And then, too,” she added more seriously, “I think it takes more bravery to fight than to do anything else.”

“Perhaps it does, Grace,” remarked Helen slowly, “but when it comes to heroism, I think the mothers who give their boys to be slaughtered for the good of their fellow-beings are the bravest—” The girl paused quickly, for she had caught sight of Nathalie’s face, and remorsefully felt that what she had just said only added to her friend’s distress. “But, girls,” she went on in a brighter tone, “I have something to tell you. I’m going to France to do my ‘bit,’ for I’m to be stenographer to Aunt Dora. We expect to sail in a month or so. You know that she is one of the officials in the Red Cross organization.”

There were sudden exclamations of surprise from the girl’s two companions, as they eagerly wanted to know all about her unexpected piece of news. As Helen finished giving the details as to how it had all come about, she exclaimed, with a sudden look at her wrist-watch: “Goodness! Girls, do you know it is almost supper-time? I’m just about starved.”

“Well, jump into the car, then,” cried Grace Tyson, “and I’ll have you home in no time.” Her companions, pleased at the prospect of a whirl in the new car, gladly accepted her invitation, and a few minutes later were speeding towards the lower end of the street where Helen and Nathalie lived.

After bidding her friends good-by, Nathalie, with a tru-al-lee, the call-note of their Pioneer bird-group, ran lightly up the steps of the veranda. Yes, Dick was home, for he was standing in the hall, lighting the gas. With a happy little sigh she opened the door.

“Hello, sis,” called out Dick cheerily,—a tall well-formed youth, with merry blue eyes,—as he caught sight of the girl in the door-way. “Have you been on a hike?”

“Oh, no, just an afternoon at Mrs. Van Vorst’s. Nita had a lot of the girls there—” Nathalie stopped, for an expression, a sudden gleam in her brother’s eyes, caused her heart to give a wild leap. She drew in her breath sharply, but before the question that was forming could be asked, Dick waved the still flaming match hilariously above his head as he cried, “Well, sister mine, I’ve taken the plunge, and I’ve come off on top, for I’ve joined the Flying Corps, and I’m going to be an army eagle!”

“Flying Corps?” repeated Nathalie dazedly. “What do you mean?”

“I mean, Blue Robin, that I’m going to be an aviator, a sky pilot,” replied the boy jubilantly. “I made an application some time ago to the chief signal officer at Washington. I was found an eligible applicant, for, you know, my course in the technical school in New York did me up fine. To-day I passed my physical examinations, and am now enlisted in the Signal Corps of the Signal Enlisted Reserve Corps. I’m off next week to the Military Aëronautics School at Princeton University. It’s an eight-weeks’ course. If I put it over,—and you bet your life I do,” Dick ground his teeth determinedly,—“I go into training at one of the Flying Schools, and then I’ll soon be a regular bird of the air; and if I don’t help Uncle Sam win the war, and manage to drop a few bombs on those Fritzies, I’ll go hang!”

For one awful moment Nathalie stood silent, staring at her brother in dumb despair. Then she turned, and with a blur in her eyes and a tightening of her throat, blindly groped for the stairway. But no! Dick’s hand shot out, he caught the hurrying figure in his grasp, and the next moment Nathalie was sobbing on his breast.
