"I'm awfully sorry," she said. "I just plain forgot! And I usually have some in the autogiro, but those thieves took it out.... Wait, though! There may be some on the island. We left a half a dozen cans with this girl."

A search of the little "houses" farther in on the island revealed what she had been hoping for—the remainder of the supplies the boys had left with Susie, consisting of two cans of baked beans, tea, coffee, sugar and canned milk. This ought to be enough for their lunch, and she ran back immediately to the men with the good news.

For the next two hours Linda searched the island diligently, calling Susie by name at frequent intervals. But no answer came in reply, and she found no trace of the girl. Susie had completely vanished.

Weary and hungry she returned to the shore of the island where the men were working, and was delighted at the progress they had made. The job was almost finished.

"I can't find the girl," she told them. "But I've collected enough fire-wood to cook our coffee and beans. We'll have our lunch in a little while."

Two hours later the autogiro was finished, ready for its flight back to Jacksonville. The engine was running smoothly; Linda climbed into the cock-pit and took it up in the air for a test flight. She found everything satisfactory; dipping low, she gave the others the signal to leave. With her Ladybug in the lead, the two planes made record time back to Jacksonville.

"She's as good as new," she told the mechanic joyfully, after both planes had landed, and she was paying her bill. "I wish I could fly her right over to my hotel."

"I believe you almost could," remarked the man, admiringly. "Land her at the front entrance, like a taxi-cab!"
