Suddenly a window flew up and a head poked out. It was a stranger, none of the boys ever having seen the fellow before.

"What do you want?" the man demanded in a truculent tone.

"I call upon you to surrender, in the name of the law!" said Hawkins.

"You what?" Without waiting for an answer, the head drew in but the window remained open. In a moment the head reappeared.

"What are you talking about? Why should we surrender?"

"You're under arrest for smuggling, and for assault and battery with intent to kill!"

"You don't say!" The head popped in. Then in a moment——

"Who are you—John Law?"

"I happen to be a federal agent. But I'm not here to give you my history. Do you surrender?" The boys could hear the sting in the agent's words.

"Wait a minute." Once more the head disappeared. This time it stayed back for some minutes. The watching boys were moving uneasily. Finally another came to the window—it was Delton. The agent gave no sign that he knew him.
