"Antoinette is a very nice girl," he said. "I'm sure she would appreciate Hal's interest in her. I'll tell her about it."

"I say! Don't do that!" exclaimed Hal in some confusion.

"Ha, ha!" laughed Chester.

Hal sat down again, his face still burning.

Even the Canadians joined in the general laugh, and Hal himself smiled. The joke was on him, and he was not the lad to get angry.

"Oh, well, have it your own way," he said. "It does no good to deny it."

The day passed slowly.

Antoinette did not appear at noon with food and water, as the others had expected she would.

"Probably busy serving the German officers," said Hal. "What's the difference, though. We can get along very well without one meal."

Night came, though to those in the little secret room it was not apparent that darkness had fallen. Hal glanced at his watch. It was after 7 o'clock.
