They found a building in Bar-le-Duc that could be used, and which would hold a respectable sized audience. Little preparation was needed save to build a stage and get seating arrangements. Where chairs were not available benches had to take their place. Lights were also provided, and what few accessories they needed, such as curtains and stage scenery, were improvised after a fashion.

In the spirit of fun that prevailed "any old thing went," as Jack expressed it. The makeshifts that came to light when the performers appeared dressed for their various parts were many and startling. They had borrowed or begged anything that promised to answer the purpose from a long-tailed French coat to a lady's highly colored shawl. Wigs had been sent for, and Paris had responded with an assortment that left nothing to be desired.

The members of the two French air squadrons whose headquarters were near by, had entered into the affair with great zest. They blessed the little Irish pilot for his suggestion. And Sergeant Barney McGee was on the jump all day long, displaying all the sterling traits that distinguish able generals and leaders of men.

The time approached when the entertainment was to come off. The performers were sure of a full house, provided no war orders were issued that would interfere with the arrangements.

"Since Fritz has kept quiet for so many dreary days now," one pilot was heard to say on the morning of the entertainment, "let us hope we'll have just one more peaceful evening to reap the reward of all this training. It would break the heart of Sergeant Barney if the order came for every one to buckle down to hard work just when his big show is about to come off."

The weather man proved friendly, for he gave them a splendid day, with the promise of a moonlight night. Besides, the cold had pretty well vanished, and it was really becoming more seasonable, with the sun warming the earth, and the mud drying up to a considerable extent.

When the show opened that night it was to a house jammed to the doors. Even the windows were utilized for seating room; and crowds stood without, unable to gain admittance.

"Some crowd, eh?" remarked Jack, as he watched the airmen, soldiers and others pouring in.

"I should say so!" cried Tom. "I hope we make good."

It was certainly a unique performance, considering the fact that it was given in a camp close to the battle lines; and that at any hour every one of those who were dressed so fancifully and conducted themselves as actors born to the stage, might be called on to mount to the clouds, and perform their dangerous work of fighting for France, perhaps even giving up their lives.
