Linda shot a swift glance at the approaching boat, then looked again at the floor, where the water was fast deepening. Would the rescue come in time? And would the boat stop at their signal of distress?

Wild with excitement, both girls raised their arms and waved desperately at the approaching craft, until it was only fifty yards away. Then they both shouted with a power and volume that they would not have believed they possessed.

The oncoming boat decreased its speed until it was almost beside the girls' sinking craft. To their overwhelming joy and relief, they saw that it was stopping. A man appeared on the deck, and called to them in a pleasant voice.

"In trouble, girls?"

"Our boat's sinking!" shouted Linda to Dot's amazement, for the latter was still unaware of the immediate tragedy that was threatening them. "Can you take us aboard?"

"Sure!" he replied. "Wait till I get a rope ladder."

While he was gone, Linda pointed to the water in the boat, which by this time Dot had seen, and signaled to the other girl to say nothing of their experiences to this man, until they learned more about him. Linda's recent association with criminals had made her exceedingly wary.

"Pull up closer," instructed the man, as he returned with the ladder. "Now, can you climb?"

"Easily!" Dot assured him. "We're in knickers, anyhow."
