“While everyone knows we’re regular Commandos,” Louise retorted sarcastically. “Why, if necessary we could go an entire day without eating.”

“That’s exactly what we will do,” announced Penny with renewed determination. “I’ll stay here until Sara comes if it kills me. But I hope you slug me if ever I get another idea like this.”

“Don’t worry, I will,” promised Louise. “In fact, I may not wait that long!”

The hours dragged slowly on. All amusements failing them, the girls took turns sleeping. Twice they went to the ark, but Old Noah had not returned.

At last, as shadows lengthened, Louise and Penny were confronted with a new worry. It occurred to them that Sara might not expect to take over her duties until long after dark. The air had grown chilly, and hungry mosquitoes were swarming from their breeding places.

“Even my Mother doesn’t seem concerned about me any more,” Louise moaned, slapping at a foraging insect.

Penny glared at the motorboat snugly hidden in the underbrush. “If that thing weren’t worth so much money, I’d certainly chuck this job. Even so, I’m just about desperate.”

Louise, huddled against a tree trunk, suddenly straightened alertly. Placing a warning finger on her lips, she listened.

“Someone’s coming, Penny!”

“Maybe it’s Sara with a basket of food. I’d rather see her than a dozen saboteurs!”
