"Seventy miles an hour," said Leon. "Did you like it?"

"I did not," said Earl warmly. "That's too fast for me."

"There are no shell-holes in the air anyway," said Earl. "We can't be wrecked that way as we nearly were back there on the road."

"Don't you believe it," exclaimed Jacques. "When they begin firing at us from the German trenches you'll find there are plenty of shell-holes in the air all right."

"By the way, haven't you any idea where we're going?"
