"Perfect idiot!" responded Nan. "I should think your brother would just duck her in the water some fine day when she's making those sheep's eyes at him. I would if I were in his place."

"Oh, he doesn't care. He thinks she's lots of fun. Besides, he's going away to-morrow, and won't see her again unless Helen makes her stay longer."

"What'll she do for some one to make eyes at?"

"Don't know. Helen generally has a lot of company, but just now there seems to be a famine in the land!"

Suddenly Nan stood stock still.

"What's the matter?" demanded Ruth.

Nan waited a moment, and then bent over and whispered something in her ear.

"Magnificent! We'll do it!" cried Ruth, clapping her hands, and breaking into a peal of laughter.

"Not to-night—while your brother is here!" protested Nan.

"Of course not. To-morrow though, sure. Carl will be gone and the coast clear, and meanwhile we'll drill."
