Madge heard Phyllis Alden's and David Brewster's voices, yet she could not call out to them for aid.

She saw some one pull aside the low branch of a tree, then David's face appeared, discolored with anger as he caught sight of her. Before the man who had seized her could strike at the boy David had grasped him by both shoulders and hurled him to the ground.

Whipping out his knife David cut the cords that bound Madge and raising her to her feet, placed one arm protectingly around her. Her captor had also risen and stood glowering at David without offering to attack him. The boy's rage was so terrifying that even this hardened lawbreaker quailed before it.

"We didn't mean any harm," mumbled the old woman. "You know us, boy. You know we wouldn't hurt the young lady. You won't say you saw us, will you?"

But ignoring her question David turned to help Madge back to her friends.


CHAPTER VIII
THE MOTOR BOAT DISASTER

IT was Miss Betsey Taylor who had first discovered Madge's absence. Just before daylight she awakened with the feeling that some one had stolen into her stateroom, for she was dreaming of her lost money. Miss Betsey sat straight up in bed and looked about her small cabin. There was no one to be seen.

"Miss Betsey," called Miss Jenny Ann from the berth above, "what is the matter?" Nor would Miss Jones go back to sleep until she had explored the houseboat thoroughly.

As she stole into the next cabin where the girls slept she noticed that Madge was not in her bed. She must have heard the same noise that had disturbed Miss Betsey, and gone to investigate the cause. But Miss Jenny Ann could not ascertain the cause of the noise nor did she find Madge on the decks. She aroused Phil and they sought for her together. Then Eleanor and Lillian joined them, and Miss Betsey, a prey to curiosity, came forth to find out what all the commotion was about.
