Then a clever thought occurred to some one of the men. Perhaps it was suggested by a happy-go-lucky Irish aviator who was connected with the British air forces, and wore the marks of distinguished service on his arm and cap.

Sergeant Barney McGee had received a month's furlough in order to recover from injuries which he had sustained. Instead of going back to Ireland to spend his enforced vacation, as one might naturally expect him to do, McGee put in the time visiting other parts of the long front between Ypres and Verdun.

After all, there was nothing so very singular about that. Give an old railroad engineer a week off, and presently you will discover him spending the time loafing around the roundhouse, chatting with the other engineers, and investigating things. His whole life being wrapped up in his work his idea of a vacation consists of being free to watch his fellows of the same craft work.

Sergeant McGee was an exceedingly droll chap. He spent a couple of weeks with a French cousin who was also an aviator, and in time came to know the jolly members of the Lafayette Escadrille. He grew to be exceedingly fond of them all, and was in the mess-room nearly every night.

His idea was that they should get up a show to pass these dull evenings away. If the enemy allowed them sufficient time they could even give a public performance, and give the proceeds to the Red Cross.

It took like wildfire with the Americans, casting about at the time for some way to kill dull care, and make the hours pass more quickly until called to action again.

A survey developed the fact that there were a number in and out of the Lafayette Escadrille who possessed a talent of some kind or other. This one had a violin which he loved to play; and, while not a finished artist, he was able to make real and lovely music by means of his clever bow. Another, it turned out, had a good tenor voice, and knew many of the most popular songs of the day. A third showed a talent for mimicking well known people, particularly Americans of national fame. Several agreed to black up, and give a humorous little minstrel skit that they declared would set the house in a roar.

It was Barney McGee himself who most astonished the Americans, however. At the first rehearsal he appeared before their astonished eyes dressed to imitate a well known and popular moving picture star and he carried out the part in a fashion that caused the wildest excitement. From that moment the success of the show was assured.

They made feverish preparations, for no one could tell just when the period of inaction would come to an end, and every available member of the several fraternizing escadrilles be ordered to rush to the front again, to take his life in his hands, and risk it hourly for the great cause.

Tom and Jack both had parts in the entertainment. Jack made a good "bones" for the minstrels, and he coaxed his chum to don a burnt-cork face for that one evening, and show what he could do as a comedian of parts.
