“Not a chance; nor is that little chap back there beyond Fort Chipewyan, the one with the carrier pigeon.”

Curlie showed his disappointment at this fresh discovery. He had come a long way on a wild goose chase. He had hoped against hope that this cabin might furnish a clue to the solution of the mystery that gathered itself about that gray rover of the sky. Yet here was Jerry telling him there was not a chance.

“But why didn’t he tell us he was a trapper?” he objected.

“These men of the North are silent fellers,” Jerry said slowly. “You’ll find that out. They live in the midst of silence. They’re here because they love silence. People that like cities live in ’em and talk aplenty.

“One thing helps,” Jerry added after a time. “Our record is still good. We’ve added a grand distance to our total year’s flight and, this being an errand of mercy, counts extra special.”

Curlie smiled as he thought what an accidental errand of mercy it had been.

“But not so much an accident after all,” he said half aloud. “God planned it, beyond a shadow of a doubt. And what God plans can never be called an accident.”

The baggage their passenger proposed to take with him was proof enough that he was a trapper. This was composed of bales of white fox skins.

“This,” he explained, “is only part of our catch. My partner left with the rest on our dog sled five days ago. It’s five hundred miles to Fort Chipewyan. You have to carry food for yourself and your dogs. We didn’t dare try it together. Too much of a load for so long a journey. I was to come down later. But now,” he smiled, “guess I’ll beat him out. That’s the glory of the air.”

“Yes,” Curlie agreed, “that’s the glory of the air.”
