Quick to act as to think, Ned picked Dorothy up in his arms and turned into a natural hiding place.

"There, they have not seen you! Let them look—further on!" he whispered.

Of course the others could not even guess what had caused the sudden change in Dorothy's manner, but Ned knew it was not mere excitement.

"Here," he said, "is a pillow of moss. You and Cologne stay here, while I go out and see the hospital men. I will assure them no patient of theirs is with us."

Dorothy lay back exhausted. If only they would go along! But suppose they should find Tavia, and take her to that dreadful asylum!

Voices, very near, gave her a chance to listen. She heard some one say that a young girl had that morning escaped from the institution in the house canoe, and that the boat was now lying close by.

But in turning into the deep brush the strange men had not actually caught sight of the frightened girls, as the heavy woodland offered all sorts of excuses for visions.

"Well, we must get her," said one of the men. "She walked right past me, and said 'good morning.' But how was I to know who the new nurse, or the new patient was? The trouble is now with the mother. She is beyond consolation."
