"But how can we get word to her if we haven't her address?" Connie Danvers asked. But Rose answered her impatiently.

"I've thought of that," she said, then went on to explain while the girls listened eagerly how she had taken some letters to the mail box for Miss Race, and, happening to glance down, had seen that the top one was addressed to Miss Walters.

"But how are we going to get word to her?" asked one of the girls, and they looked at each other helplessly. "'The Pickles' won't let anybody outside the Hall, and they'll look over all the mail."

"No, I can't sleep," said Vi miserably. "I keep thinking of Billie and where they've put her and—and—everything."
