"Glad to know you," said Rose Belser with a quick little nod of her black head. Then she curled herself on the foot of Billie's bed and proceeded to make herself at home.

"I've been staying here for the summer," she told them. "It's an awful place to spend the summer, you know. First time I ever did it, and I never was so lonesome in my life."

"Why, I'd love to spend the summer here," said Vi, thinking of the beautiful country they had glimpsed and the lovely lake where one might row or canoe to his heart's content. "The country's so pretty, and you have the lake——"

"Oh, the lake!" the girl interrupted impatiently. "And the country! I'm tired to death of the lake and the country. I want to go to the city where you can wear pretty clothes and go to parties and things."

"But I should think you could wear pretty clothes here," said Billie, wondering. "And as to parties—I thought you always could have parties at boarding school——"

"Maybe you can at some boarding schools," the girl interrupted again with that same impatient toss of her head. "But those schools don't have Dill Pickles for guardian angels."

The girls looked at her as though she had gone crazy, and indeed for a moment they thought she had. But Rose Belser gave a short little laugh and went on to explain.

"The Dill Pickles are two old-maid sisters. One of them brought you up here——"

"Miss Dill!" cried Billie, beginning to see light. "Oh, has she a sister?"

"Yes. And the sister is worse," said the girl, with a little grimace. "They are Miss Ada and Miss Cora, and Miss Cora is the terror of the Hall. If it weren't for Miss Walters——But say, you'd better hurry," she interrupted herself suddenly and jumped to her feet. "It's almost time for the lunch gong to ring, and if you're late for lunch, Miss Cora will be furious. She has charge of the dining hall, you know. You'd better wash and straighten your hair. Miss Cora looks you through with a gimlet eye."
