As the Eagle circled about in a widening spiral Harry and Jack looked over the rim of the fuselage at the country spreading like a gigantic map in bas-relief beneath them.

A tiny glow from the cowl lamp in front of the pilot's position showed Ned that the Eagle was now headed almost directly west, while the indicators showed an altitude of approximately three thousand feet. At a speed approximating forty miles per hour the great bird-like machine winged its way with its burden of adventurers.

"Tell you what, boys," Jack said presently, growing weary of trying to discover features in the obscurity below that covered the landscape, "this makes me feel just like I imagine that old guy must have felt when he went out after the Golden Fleece or something or other."

"Who was that?" asked Harry as he reached for the binoculars for the purpose of scanning their position in the hope of discerning some indication of their whereabouts. "What are you talking about?"

"Well, I guess it was Jason," answered Jack. "Remember the stories Ned was reading to us about those old Greeks and others?"

"Oh, yes, now I do remember. But where do we resemble him?"

"Well, he went out after a great prize, and we are after the same sort of thing, only with us we want live game. We are after the prize of Jimmie's freedom and safety."

"Good thought!" cried Ned. "And, like the chap in the story, I am sure we'll go after the prize with the same determination and resolve to win out at all costs."

"You're right, we will!" exclaimed Harry with vigor. "We won't rest content until we have Jimmie away from those German Uhlans!"

"And Dave, too!" put in Jack. "We can't forget the fact that he wants to get back as well as Jimmie. And he's done us pretty good service, while we're speaking about him."
