"We've come along pretty well so far," said Gregory. "We won't give up now."

"Who said anything about giving up?" Chester wanted to know. "Of course, we won't give up. Have you any idea where we are, Hal?"

"Well, I should judge we are pretty close to the town of Cambrai. Personally, I believe the best plan would be to head in that direction. I judge it to be directly south."

"But it is within the German lines," Chester protested.

"True, but once there we may be able to find a hiding place. In the open we wouldn't have much chance if we failed to get beyond the lines before daylight overtook us."

"You may be right," said Chester. "Once in Cambrai, providing we can find a hiding place, we can figure out a means of leaving the German lines."

"Exactly," said Hal, "and with a better chance of success."

"Suit you, men?" asked Chester.

"You're the doctor," said Gregory. "Lead the way. We'll follow." Hal and Chester turned abruptly to the left. "South it is, then," said Hal.
