“A battle?”

“Oh, sure! We can fight a battle, a real battle. Grandfather has two tommy-guns. You ought to see him shoot them. Even Miss Jane Morrison can shoot them, and so can I.”

How strange all this seemed to Norma as she sat there in the glorious sunshine watching the eider ducks who had come up again some distance away.

“Why did they crash dive?” she asked at last.

“Because they heard a plane. I heard it, too. It was coming from the land, an American fighter plane. I can tell them when I hear them, yes, and when I see them, too.

“You should have heard those men on the sub,” Patsy laughed. “How they jabbered! They went down below, then they crash dived.”

“What did you do?”

“I jumped up and told Grandfather, and he told Beth and Bess and they told the fort. Pretty soon there were just lots and lots of planes, but just no sub at all.”

“Too bad,” said Norma, “but how did your grandfather tell Beth and Bess?”

“Shish!” Patsy put a finger to her lips. “That’s a military secret.”
