“Yes, that’s what makes me so worried about them. I never could teach them to be cautious. If it were you, Terry, I would feel almost certain that you’d find a way out of your trouble.”

“Thanks, Dad!” The girl stooped and kissed her father tenderly. Then with a smile she ran into the house.

While Dick assented to Terry’s plan with very few words, her mother wanted long explanations. Where and how was Terry to carry out her plans? What would she do if she found the boys injured? How would she get them home?

“I don’t know yet,” replied Terry. “Ask Dad, he’ll explain everything!” Terry hurried to the stairway and called, “Prim, come here. Get into your flying togs. Pack food and water and the first-aid outfit. We are going to find Allan and Syd and they may be in bad shape.”

Terry delivered orders like a general and Prim, her twin sister obeyed like a private in the ranks. She did not stop to ask questions. Terry’s commands were always important—or interesting.

The two girls were opposites. Terry was tall for her age, slightly built, high-strung and nervous, while Prim was inclined to be plump and rosy. Her blond hair was cut short to her head. She had none of the fire of Terry’s disposition. She sort of balanced her sister’s temper, for Prim was easy-going, practical and diplomatic. She could get along with any one, while Terry with her quick tongue was always getting into trouble and making enemies. The two sisters were chums. They loved to be together. They liked to do the same things, and while Prim would never make the expert flier her sister was, she enjoyed the sport and was always ready to follow Terry’s lead.

Terry’s decision to go north and hunt for the boys did not come as a surprise to Prim. She had been half expecting it. Her whole heart was crying out with the need to do something for these boys whom they loved, and now she wondered why Terry had not thought of it at once.

Prim needed no instructions regarding her part of the work to be done. A thermos bottle of hot coffee, bandages and food were packed into the plane, then Prim ran to get into her flying outfit. It was a jaunty flying suit, a white fleece-lined jacket, and baggy breeches, high white boots and helmet to match. Prim was fond of dress and her white togs were always in order. Terry had chosen a more practical outfit of brown leather. It was trim and smart and Terry carried it well. She had style.

Terry had left the details of supplies to Prim, knowing that her sister’s part would be done well. She hurriedly examined her plane, looked over the instrument board to see that everything was in order, tested the engine, took on a supply of gas and oil and in less than an hour was all set and ready to go.

Alice Mapes could never see her two daughters take-off without a feeling of dread. She had none of the confidence of the flyer. Although she had flown with her husband ever since her marriage she could never be persuaded to take the controls herself and learn to fly.
