"Good idea!" assented Jimmie. "But do you know how to steer?"

"Yes. Southeasterly is the general course. I'll make it a little southeast by east about a quarter south, for we flew some distance to the southward of Havre in crossing the river before we were overhauled."

"We ought to see the lights of Paris when we get up higher, anyway," Jimmie suggested. "How big a place is Paris? How far is it?"

"It is a little bigger than Peapack, N. J.," replied Jack, "and is just about a hundred miles from Havre, unless they have moved it since the last maps were made. I don't think they've moved it, though!"

"Would they move it if the Germans took it?" asked Jimmie, with a grin at his tormentor. "I don't suppose the river is near enough the ocean to be 'tied'!" he added. "That last is a pun!"

"Well," returned Jack, "I understand they would move all but the stores where writing paper and envelopes are sold!"

"Oh, I know that one!" shouted Jimmie. "They're 'stationery'!"

"I see a light ahead!" cried Harry. "What is it?"

Out of the darkness ahead the boys descried a train with lights carefully guarded. In a short time the Grey Eagle was sweeping near the flying monster as it wound its way across the country.

"Chase 'em a little way, Ned!" suggested Jimmie.
