"Not for me," drawled Chase. "I'm going to read all day and forget there is such a thing as war."

Dunstan, on the other hand, was decidedly enthusiastic.

"Sure, I'm going," he declared.

"Bully for you!" cried Don. "Hooray! We'll have a dandy time."

Immediately after breakfast the two left the Hotel de la Palette, and in due course reached that section of the country where the battery was located. By the aid of information which a sentry kindly gave them the boys discovered Lieutenant D'Arraing conversing with the crew of one of the big guns located behind a group of trees. His eyes brightened at their approach.

"Ah, bon jour, mes Americaines!" he cried, in cordial accents. "Your visit is very well timed indeed—unless you have already run into so much danger that you do not care to risk any more."

"Try us, and see," said Don, smilingly.

"I will take you at your word. One of our airplane observers brought in a report to the effect that he has very strong suspicions that the Germans have erected a wireless station on a certain building behind their trenches."

"Aha!" exclaimed Dunstan, interestedly.

"Of course we cannot permit any such liberty; so the captain and I shall shortly be off to an observation post, in order to spot the bursts of smoke from the shells when the work of putting that wireless plant out of commission is begun."
