“Who is it, Terry?” asked Prim.

“I wish I knew. Maybe it is a friend of Joe Arnold’s,” replied Terry as she gazed with dread toward the plane that was coming nearer and nearer to the island.

Now the plane was circling above them. The girls watched with anxiety as the pilot put it into a long, fast dive toward the near-by clearing.

CHAPTER VII

Crashed!

The girl flyers watched with thumping hearts as the plane, diving with wide open throttle, headed straight toward the plateau.

Prim gripped her sister’s arm. She felt giddy and faint. A cry escaped her.

Terry turned to her with a frown. “Snap out of it, Prim! This is no time to get hysterical. That plane may be piloted by a friend of Joe Arnold. If it is, we’ll need to do some quick thinking. Don’t lose courage now!”

Prim was gazing toward the plane. “It looks to me as if there were two men. And someone is waving! Do you think it’s a rescue plane?” cried Prim.

Terry did not answer. Every nerve was tense as she watched the plane banking and circling for a landing. She dared not tell Prim that she believed it was Allan and Syd. It would be too great a disappointment, if she were mistaken.
