Linda was silent, thinking of Mr. Eckers' remark about girls the day before. Yes, he must be right, their ambition usually ended with the government's permission to fly.

"I'll miss you dreadfully, Nance!" was all she said.

"You must fly to New York often," urged the other.

The country over which the girls were flying was beautiful and the air delightful. As they went farther south, they recognized real evidences of spring in the foliage. The little plane hummed gayly on, with never a disturbance in its sturdy motor. Linda was exceedingly happy.

Noon-time came, and they ate their sandwiches and drank the coffee which Linda's kind-hearted landlady had insisted upon providing, but they did not stop. Everything was going so wonderfully that they hated to break the spell. At this rate they ought to reach Birmingham long before dark.

It was about two o'clock that they met with a strange adventure. Flying along at an even rate, high enough to span the woods that loomed ahead of them, there suddenly appeared, out of nowhere it seemed, what the girls thought to be a formation of airplanes.

"Go carefully!" warned Nancy. "Don't forget that awful accident a while ago, when several planes were flying in formation!"

Linda curved to the side, but the planes seemed to be flying straight at her.

"They haven't any sense at all!" she cried, in exasperation, now seriously fearing disaster.

On they rushed, till a cold fear gripped Linda's heart. Try as she might, she couldn't get out of their way! It was all like a dreadful dream, when something menacing rushes inevitably towards you, yet you are powerless to stop. Then, in a flash, Linda perceived what the formation was.
