"Certainly."

"How far are you going to take us?"

"That depends upon circumstances. I don't know yet where or when we will be able to make a landing."

"It is horrid of you to treat us so."

"Sorry you don't like it, but it can't be helped," answered Dan Baxter, coolly. He paused a moment. "Say, if I unlock that door and let you out will you promise to behave yourselves?"

"What do you mean by that?" questioned Dora.

"I mean will you promise not to scream for help or not to attack myself or Lew Flapp?"

"I shan't promise anything," said Nellie, promptly.

"I don't think I'll promise anything either," joined in her cousin.

"Humph! You had better. It's rather stuffy in that little stateroom."
