Nathalie Page halted, and, swinging about, peered intently at the brown-uniformed figure of a young girl seated at the steering-wheel of an automobile, which was speeding quickly towards them. Yes, it was Grace, who, in her sprightliest manner, her face aglow from the invigorating breezes of an April afternoon, called out, “Ah there, girls! How are you? Oh, my lucky star must have guided me, for I have something thrilling to tell you!” As she spoke the girl guided the car to the curb, and the next moment, with an airy spring, had landed on the ground at their side. With a sudden movement the uniformed figure clicked her heels together and bent stiffly forward as her arm swung up, while her forefinger grazed her forehead in a military salute. “I salute you, comrades,” she said with grave formality, “at your service as a member of the Motor Corps of America. “Yes, girls,” she shrilled joyously, forgetting her assumed rôle in her eagerness to tell her news, “I’m on the job, for I’m to see active service for the United States government. I’ve just returned from an infantry drill of the Motor Corps at Central Park, New York. “No, I’ll be honest,” she added laughingly, in answer to the look of amazed inquiry on the faces of her companions, “and ’fess’ that I didn’t have the pleasure of drilling in public, for I’m a raw recruit as yet.

But isn’t my new car a Jim Dandy?” she asked, glancing with keen pride at the big gray motor, purring contentedly at the curb. “It was a belated Christmas gift from grandmother. “But I tell you what, girls,” she rattled on, “I’ve been put through the paces all right, but I’ve passed my exams with flying colors. Phew! wasn’t the physical exam stiff!—before a regular high official of the army medical corps. I was inoculated for typhoid, and for paratyphoid. I’ll secretly confess that I don’t know what the last word means. Yes, and I took the oath of allegiance to the United States Government, administered by another army swell,—and that’s where my Pioneer work proved O. K. And then we had the First Aid course, too, at St. Luke’s. The head nurse, who gave us special lessons in bandaging, said I was A No. 1; and in wigwagging, oh, I did the two-flag business just dandy.”
