"What's the object in changing clothes?" asked Hal.

"It may help a bit," replied Chester. "If we went back in civilian attire we would undoubtedly be shot."

"I don't see that changing now will help matters," said Hal.

"Well, I hardly think so, either; but it may."

Attired in the uniforms of French lieutenants, the boys were at last ready to go; but, before leaving, Hal drew the dispatch he carried and put it into the hands of the French officer, saying:

"Will you have this forwarded to General Joffre at once?"

"It shall be done," was the reply. "I shall attend to it immediately."

"I guess that's all, then," said Chester. "Good-by."

The French officer shook hands with them warmly.

"You are brave," he said simply, as the lads left him.
