“Tom will be ready for duty before long,” said Jack, as Ned left the pilot house, passing, as he made his way aft, Tom, who looked white and ill. But he assured Ned it was nothing, simply an attack of air-sickness which would soon pass over.

Ned took up his place in the stern between the two long supporting frameworks of the rear propellers. The wind was terrific but otherwise he felt no inconvenience except from the excessive vibration. He had not been standing there more than a few minutes, keeping a watchful eye all about him, when he noticed that the port stern bearing of one of the propellers was beginning to smoke.

“Hullo! We’ll be having a hot box first thing we know,” said Ned to himself. “I’ve got to oil that fellow and look sharp about it, too.”

He glanced out over the path he would have to travel. Ned was a plucky boy, but he felt a qualm pass through him as he looked. The propeller was fully ten feet out from the main structure of the craft and was supported by a thin framework of braces.

The task in front of Ned was to straddle this framework and make his way aft to the heated bearing, with nothing but 2,500 feet of space beneath his shoe soles. For a minute he felt tempted to ask Jack for instructions. But then his pride, always keen with Ned, came to his rescue.

“I’ll do it,” he determined, taking a firm grip on his faculties. “But it’s going to be some job.”

He gripped his oil can firmly, resolved to waste no more time. Then clambering up to the framework, he straddled himself over the top part of it, holding on to the lower part of it as best he could with his feet.

It was like riding a bucking broncho in mid-air. The gale from the big propellers swept around Ned like a hurricane. He felt his cap swept off his head and dared not look downward to watch it go hurtling toward the sea. He knew that the sight would be too much for his nerves.

Rallying himself with an effort, Ned began his dangerous crawl along the framework. The further out from the main structure of the craft he got the more nerve-racking became the task. The slender framework shook and swayed as if it was determined to shake him off, and send him flying into space.

Ned gripped his handholds till the paint flaked off on his palms. But little by little he managed to work his way toward the bearing. The propeller, a whirring blur before his eyes, dazzled him. The wind from it seemed to catch his breath and jam it back down his throat. He clung to his perch with the courage of desperation.
