"Trust the dear little one to arrange all," said Elsie in her pretty way.

"We will have a good many thrills, I think," said Helen, laughing, "between Mabel's experiment and that funny new girl, Claire Maslin."

Mrs. Horton looked grave.

"Say, Mabe," he exclaimed, "who is the nifty red-head with the Chinese footman? Some style, I say. Who is she?"

"A new Girl Scout," said Mabel absently. Even the mysterious stranger was crowded out of her thoughts by the new orders she was about to follow.

"Well, don't you know her name, or where she lives, or anything about her?" demanded Frank.
