e ready to lend a hand, Jack."

He fumbled in a pocket of the body of the plane, producing a small roll,
which, upon being opened, disclosed several plugs of soft wood, such as
might easily swell if moistened. There was also some wax, the kind fruit
growers use in grafting new scions on old trees.

Tom carefully examined one of the holes in order to learn its exact
dimensions.

"Just as I expected, it's perfectly round in shape, which makes it
easier to plug up," he announced, pleased with his discovery.

A minute later he had fitted one of the wooden pegs in tightly. Then he
used the wax, which was just hard enough for his purpose.

"That one is finished, and I think it will hold fairly well," he
remarked, somewhat to the surprise, as well as delight, of his
companion, who had anticipated that it would take much longer.

"You're a sure-enough wizard, all right, Tom," was his gratified
comment. "Why, you're getting things put through in a jiffy. But I hope
there isn't any danger of the petrol acting on the wax, and causing a
quick leak."

"I've tested it, and feel certain it will hold for an hour or so,
anyhow, Jack. And by then we ought to be back in camp."

"Will, if we have any luck at all," asserted Jack.

"Now I'll get busy on the other hole," continued Tom. "Though that isn't
so important, as it's at the top of the reservoir. Still, it might be
just as well to close it up in order to avoid waste. Besides, there's
always danger of an explosion if your tank sprinkles this deadly stuff
around."

Jack took occasion to step aside to where he could look up between the
trees and glimpse the dimly seen chateau, knowing now just where to look
for it. When he came back he had information to impart that he thought
would please Tom.

"Still a blaze up there, Tom, showing that the conference isn't over
yet."

Presently Tom straightened up.

"That is all done," he announced, in a satisfied tone. "And done well in
the bargain. Now bring along your gas, and be careful how you pour it
in. By good luck I've got a funnel that can be used. I'll hold it while
you start things going, Jack. Easy now, no hurry; every drop is precious
remember!"

The contents of the little pail was presently successfully transferred
into the reservoir which Tom had so adroitly mended after its rough
treatment at the hands of the Huns who worked the "Archies," or
anti-aircraft guns.

Tom gave a sigh of relief when that part of the proce
