Amy was a girl of quiet disposition, and while she had not been altogether happy during the time she was unable to solve the mystery about her identity, when that problem had been cleared up she was of a much brighter disposition. Still, the years of quiet had had their effect on her.
Betty Nelson, often called the Little Captain, because she was such a born leader, was the only daughter of Mr. and Mrs. Charles Nelson, the former a rich carpet manufacturer. Betty loved, to "do things," as witness her assumption of the summer plans of her chums.
Grace Ford was tall and slender, and often spoken of as a "Gibson" type, by those who admire that artist's peculiar, and always charming, conception of young womanhood. Grace lived with her father and mother, the other member of the family being her brother Will, a hasty, impulsive lad, whose character had, more than once, gotten him into trouble, to the no small annoyance of Grace. Grace had one failing, if such it can be called. She was exceedingly fond of chocolates and other sweets, and was never without some confection in her possession.
And then there was Billy—as Mollie Billette was nicknamed. Mollie was the daughter of a well-to-do widow, Mrs. Pauline Billette, whose French ancestry you could guess by her name and by her appearance and manner. Mollie was a bit French herself. There were two other children, the funny little twins, Paul and "Dodo," as Dora called herself in her lisping fashion. Paul and Dodo were at once the loving care and despair of Mollie and her mother.
So much for the four chums, who were known as the Outdoor Girls.
After their activities, as set down in the first volume of this series, they were next heard of at Rainbow Lake, where, in Betty's motor boat, the Gem, they had some stirring and exciting times.
But, stirring as those times were, they were equalled, if not excelled, when Mollie became possessed of a motor car, and took her chums on a tour which ended only when the mystery of the haunted mansion of Shadow Valley was solved.
Glorious days on skates and iceboats followed, when the outdoor girls went to a winter camp. And then came a contrast when it was learned that Mr. Stonington had purchased an orange grove in Florida, and that Amy had the privilege of inviting her friends to spend the winter in the Sunny South.
For what happened there I refer you to the volume dealing with our friends' activities amid the palms. Sufficient to say that they thoroughly enjoyed themselves. They had returned to Deepdale, their home town on the Argono River, just as spring was budding forth.
And now, this glorious day, the four girls had met once again, and were ready for something new, which something seemed to be offered by Betty Nelson.
