"Goody! now we can get the boys to shore all right," said Dora, with satisfaction. "Laura will know what to do. She always does."

Laura Belding, who was Chetwood Belding's sister, and who rejoiced in the nickname at school of "Mother Wit," was a girl who possessed a very quick mind. Her mates expected a good deal of her, therefore, and it was not surprising that Dora and Dorothy Lockwood should consider that the rescue of the three boys in the lake was a simple matter now that Laura had appeared upon the scene.

In the first volume of this series, entitled "The Girls of Central High; Or, Rivals for All Honors," Laura Belding's quick wit was displayed on several occasions—notably in her solving the problem of a fire that was discovered in the office of the principal of Central High School, Franklin Sharp.

But in that initial volume was told, too, of the beginning of after-hour athletics in Central High and of the interest the girls began to take in all manner of sports and games approved by the Girls' Branch Athletic League.

The girls of Central High had ever been loyal supporters of the boys' games—had "rooted" at all baseball, football, and rowing matches, and the like, for their particular colors; but now they were to take part themselves in various lines of athletics and sports, and their real interest in such things was, naturally, much increased.

But to properly develop the idea of the Girls' Branch Athletic League, which was formed at Central High, the need of a modern girls' athletic field was plain to both the girls themselves and their instructors. Centerport, although a moderately wealthy town, could not supply fifty thousand dollars, off-hand, for such a purpose; and that was the least sum needed for the establishment of an up-to-date building and field for winter bathing, basketball grounds, tennis courts, a cinder track, and a dancing lawn.

Perhaps Laura Belding was no more interested in the establishment of such a fine field than many other of the girls of the sophomore, junior, and senior classes. Laura was a soph herself; but she saw ways and means to an end more quickly than the others. By chance she interested a very wealthy man—one Colonel Richard Swayne. The Colonel thought that little Miss Belding was quite the quickest-witted girl he had ever met. And, later, when Laura's bright thought chanced to aid the Colonel's invalid daughter, the old gentleman began to take a deeper interest in the things that interested Laura.

So that, finally, through Colonel Swayne's generosity, the idea of a fine field for girls' athletics became a possibility. This coming summer, during the long vacation, it would be built, and the girls of Laura's class were very proud indeed of "Mother Wit."

Now the two canoes, propelled by the twins in one and Laura and her chum, Jess Morse, in the other, dashed toward the three boys in the water. The power launch, flaming merrily, was allowed to take its own sweet will across the lake.

"Now, don't you tip either of those canoes over, Purt!" Chet Belding was angrily shouting as the girls reached the trio of water-soaked voyagers. "Easy! You're not drowned yet."
