d Jack scornfully. "Not for me, anyway!"

"No, but fine for the Eagle if we can get it there and find the plane
still in working order. Let's hope they haven't taken it away."

"Let's go see," suggested David. "We can take along some of this
gasoline in some of these empty tins and cans."

"You're a brick!" announced Jack. "I'm beginning to like you!"

Scrambling over the wreckage and ruins of the building, the four boys,
each bearing a vessel with gasoline, gained the street. They turned a
corner and passed along apparently unnoticed. In a short time they
stood in the vacant space where the Eagle had landed.

Before them the planes loomed large. Ned almost shouted for joy.

"There are soldiers on that hill over there!" announced Jack.

"One of them has gone crazy or something," said Harry, pointing.

"That's Boy Scout semaphore signals!" declared David.

"Answer him, Ned," suggested Jack. "Maybe he means us."

"He's spelling 'Wolf' in American," stated Ned. "Here comes more."

"Right arm above head, left horizontal--that's 'J,'" said David.

down in front, left up diagonally--that's 'E.'"

"That spells 'Jimmie!'" cried Harry in excitement.

For a time Jimmie forgot the drudgery to which he had been sentenced as

concealed in the Cossack uniform. Forgotten were the multiplicity of
duties incident to his service as a member of the "kitchen police"--the
work to which all offenders in the army were subjected, and which
corresponded to the tasks of a garbage collector.

Apparently the lad was devoting himself wholly to the strenuous labor
of calisthenics. There seemed to be no idea in his mind of making any
certain motion a given number of times for the purpose of developing
different muscles. Instead he merely placed his arms in various
positions and held them there a moment before assuming a different
attitude. Seldom did he repeat any motion.

We know, of course, that he had seen the boys as they emerged from the
underground cavern that nearly proved their tomb. He had taken a
chance on their being his comrades and had made signals to attract
their attention. When he received an answering wave of the arm from
Ned he delightedly began sending a mess
