"How will you do it?" asked Dave. "Let me help."

"I guess you'll have to do most of the work," replied Harry, reaching into one of the lockers, from which he drew a coil of light line.

"Not if you go under the fuselage to get Jack," objected Dave.

"Yes, sir!" continued Harry. "When I get down there you'll have to do all the work of engineering the deal. You'll have to do a whole lot of pulling and hauling, and you'll have to run out on one side to balance the machine. Mustn't have the ship list too much!"

"Oh, I see!" was Dave's response. "And," he continued, "I won't be able to see where you are, because you'll be on the opposite side from my own position. How shall we manage?"

"Well, here's my plan," Harry went on rapidly, as he began overhauling the coil of line. "When I get out on one side I'll go along the framework, of course. You'll be on the opposite side to balance. Then when you see that the machine is tipping your way you are to get nearer the center of gravity so as to stabilize the affair."

"I understand," Dave replied, eagerly entering into the spirit of the work. "And when I feel the machine tip away from me I'll go out farther along the framework so as to again equalize the flight."

"Exactly. Now, it will be a hard job for us to get this line passed under the framework so that we can get a purchase and pull it to Jack. I can't reach that far, and Jack probably is hanging on with his hands, feet and eyelids, so he can't let go with one hand even."

"I'll tell you how we can fix that," Dave suggested.

"How?" inquired Harry, ready at all times to consider any suggestions and act upon them if they seemed better than the ones he had made.
