"Maybe some of the boys just playing a joke," suggested Grace.

"Oh, no, the boys wouldn't wait all this time for their joke; besides, there's no fun in that," analyzed Margaret. "Please don't say anything about it, girls, but since you told me your secret, I thought I ought to tell you mine. There come the other girls. Come on for the wig-wagging. I just love to stand up on the library steps and wave. Hope Captain Clark gives me that place," and the quartette were off to join forces with others of the True Treds, with their signal flags of red and white.

It was usual to have spectators on wig-wagging practice days, and this afternoon an unusual number seemed to take time to stop and notice the picturesque scouts. The troop girls had worn their uniforms, to school that afternoon, so as to be ready for an early start, and in the glorious sunshine, striking in golden rays through the deep green elms for which the village was noted, the troop girls, with their signal flags, made an attractive picture.

Captain Clark stood far off on a mound of green, waving her "questions," and each girl answered the code as the messages were relayed and transmitted. The younger girls were promptly qualifying, and it was very evident the coming tests for higher degrees would find our especial little friends ready to advance.

Coming down from the terraces where they had been stationed, Grace and Cleo observed a handsome limousine drawn up to the curb where the occupants could have viewed the wig-wagging to advantage.

"Oh, there's that lovely girl that was in the wheel-chair!" exclaimed
Madaline.

"I believe she would speak to us if she were near enough," commented
Cleo.

"What a stunning car!" added Madaline. "What a pity the little girl cannot walk."

"That's about the way generally," finished Cleo vaguely. "But run! There go Margaret and Winnie McKay," and the bright-eyed, pink-cheeked child, so eagerly watching the girl scouts through the open window of the big gray car, was soon forgotten in the more urgent demands of the wig-wag report.

The lesson had been noted "Satisfactory" and Captain Clark had good reason to be proud of her True Treds.
