They found the sled outside where Teddy had dropped it when they entered the cave, and then there began a long, hard struggle with the snow and the wind that the boy and girl were to remember long afterward.

They did not talk much, for they were too busy trying to keep up with Nick Budd as he floundered through the snow, and breath was precious. However, Billie did find a chance to ask the question that had been looming bigger and bigger with each second.

“Teddy, what do you suppose the boys and girls will think of our disappearing like that?” she asked him.

“I suppose they’ll think we went off in an aeroplane or something,” he answered, trying to be funny and not succeeding very well.

“Well,” sighed Billie, “I only hope they won’t go and say anything about it at school—not till we get back and have a chance to explain, anyway.”

Teddy glanced at her quickly.

“Nobody would be mean enough to do that,” he said, decidedly.

“No-o, I guess not,” agreed Billie, but in her heart she was not at all sure. She was thinking of Amanda Peabody.
