It took but a minute to execute this threat, for the door was thin and frail. Both gave a hasty look around.

"Gone!"

"They must have taken the rowboat and rowed away," said Lew Flapp.

Both went back to where they had left Pick Loring and Hamp Gouch.

"The girls are gone," said Baxter. "They must have skipped in that rowboat."

"We can soon fix 'em," muttered Loring. "We'll get Sculley to go after them."

The launch ahead was signaled and soon came up alongside.

"What's wanted now?"

"Take me aboard and I'll tell you," answered Baxter, and he and Pick
Loring boarded the launch.

In the meantime the two girls had placed the oars into the rowlocks and were rowing off as fast as their strength would permit.
