Boom! The girls jumped but retained presence of mind enough to stand at attention as Allen had cautioned them. The boys were standing stiff and straight as ramrods, hands at salute, their young faces grave and tense.

The band played the "Star-Spangled Banner," and never had it thrilled the girls as it thrilled them now. It brought tears to their eyes, yet they wanted to shout with pride and patriotism. Their star-spangled banner, oh, long might it wave, o'er the land of the free and the home of the brave!

"Allen, Allen!" cried Betty when it was all over and they had turned away, "I'm proud, so proud, just to be—an American!"

CHAPTER XIX

FLAMES

For the girls during the happy, work-filled, pleasure-filled days that followed, only one cloud darkened the horizon. That was the continued strange behavior of Will Ford.

About a week after their arrival, Grace had received a letter from him, saying that he was coming on for an indefinite stay. Betty found her friend with the letter clenched tight in one hand, while the other crushed a handkerchief into a hard little ball.

"Why, Grace, what is the matter?" Betty sat down beside her and slipped a sympathetic arm about her shoulders. "Tell me, have you had bad news?"

"No, I suppose you couldn't exactly call it that," said Grace wearily, folding up the letter and replacing it carefully in its envelope. "As a rule I'd think it was mighty good news. Will is coming to Camp Liberty."

"Oh, has he enlisted, after all?" cried Betty impulsively, and the next minute could have bitten her tongue out for her thoughtlessness.
