"Airship for me," said Chester; "its quicker and promises a greater degree of success."

"I'll make that unanimous," said Hal. "Airship is my vote, too."

"Guess we'd better wait until along toward midnight, though," Chester suggested.

"Why?"

"Well, chiefly because there is less likelihood of our being discovered at that hour. Guards will be posted, of course, but we've eluded them before and we can do it again. Also, arriving within the enemy's lines after midnight, will give us the chance of mingling with the German troops without so great a risk of discovery."

"Any way suits me," said Hal. "First thing to do, now that we have decided upon our means of locomotion, is to find a plane."

"I'll commandeer one from Captain Nicholas," said Chester.

"All right. Tell him to have it ready at midnight sharp."

"Right," said Chester and hastened away.

Hal meantime returned to their quarters and threw himself down upon his bunk. He was reclining at ease when Chester entered to report the airplane arranged for.
