“Yes-and he might not!” Mildred exclaimed. “He appeared to know too much for that.”
“One more thing,” Doris laughed. “Johnny thinks there is a submarine—a foreign one—in these waters!—He thinks we saw it, and that it was the thing that dragged the steel ball, that day!”
“I shouldn’t wonder a bit,” said Mildred.
“Oh, bother your ‘shouldn’t wonder’!” exclaimed Doris, good naturedly. “Come on, let’s take a walk. It will be good for our nerves!
“But I’ll tell you one thing,” she added as they started off. “If I believed half the things you do—I’d be getting out of here!”
“It’s not so easy,” Mildred replied, soberly. “Grandfather is a dear. It would be a shame to leave him alone. Of course he says he’s going to send me back to college in the fall, and I suppose I shall go. College means so much these days.”
“Yes,” Doris agreed, “I’m sure it does.”
“But he can’t do that unless we get our motorboat up from the bottom,” said Mildred. “And even after that—there are the spies.”
“Spies! Always spies!” Doris laughed. “Let’s forget them!”
“O.K. Let’s do,” the other girl agreed.
