The thought of Fatty being drawn through a knothole was so ludicrous that it provoked a general roar.

"I guess we all feel pretty well used up," said Bart when the merriment had subsided, "but all the same it's things like this that are going to help us lick the Huns."

And so the days passed in learning the grim lessons of war, and the shadows, lengthening into evening, brought supper, perhaps some special musical entertainment, a vaudeville show, or moving pictures, sometimes only bonfires with smoking, laughing, joking crowds about them. The boys enjoyed these latter evenings most when the funny events of the day could be passed in review and enjoyed by them all.

Then, promptly at nine the bugle called for "all lights out," and the young soldiers, early as was the hour, obeyed it willingly. The strenuous days in the open air made the narrow cots in the long barracks particularly appealing.

"Did you hear that joke Jameson was telling about the Yankee soldier?" Bart asked one night, when all the rest were either asleep or on the way.

"No," said Frank, sleepily. "What was it?"

"It seems a guard challenged him," chuckled Bart, "with the regular, 'Who goes there?' and he answered, 'Aw, you wouldn't know if I told you. I've only been here a couple o' days'."

"That's all very well here," yawned Frank. "But it wouldn't go in 'No Man's Land'!"
