For three weeks it had been possible to enter or leave the cave only after dark. Even then it was risky, for the mouth of the cave was only about fifty yards from the German trenches and slight sounds could be heard. After dark the Hun fire was laid down about the entrance at every suspicious noise. Sometimes the men inside would amuse themselves by heaving stones outside from a safe position within, to hear Fritz turn loose his "pepper boxes."

Despite these difficulties, Dr. Barker got a motion picture outfit into the cave and gave a show of six reels to the men stationed there, after which Y. M. C. A. men entertained them with songs and eccentric dances. Men who saw that performance, in the light of torches and flambeaux, will never forget the picture.

Toward the last there were sounds from the farther interior of the cave, and two American soldiers walked into the circle, blinking their eyes. Nobody gave much attention to them, supposing they just had wandered away a few minutes before, until one of them interrupted a song with the hoarsely whispered query:

"Got any chow?" Which is army slang for food.

"Aw, go lay down," was the querulous reply of the man addressed. "Ain't yuh got sense enough not to interrupt a show? Shut up, will yuh?"

"Gee, but I'm hungry," came the answer. "I need some chow. We been lost in this doggone cave for two days."

Investigation developed that he was telling the truth, and Dr. Barker produced from some mysterious horn of plenty some chocolate, which the famished men ate with avidity. With the natural, healthy curiosity of American youth, they had set out to explore the cave and had become lost in its mazes. Only the lights and noises of Dr. Barker's concert had led them out.

An instance of the attitude of mind of the Pennsylvania men, who felt nothing but contempt for their foes, and of how little the arrogance and intolerance of the typical Prussian officer impressed them, was given by members of the 111th Ambulance Company, working with the 111th Infantry.

Soldiers of Pennsylvania Dutch descent had amazed the Germans more than once not only by understanding the conversation of the enemy, but by their intense anger, almost ferocity, which they displayed on occasions when confronted with "the Intolerable Thing" called the Prussian spirit. Offspring of men and women of sturdy, free-minded stock who fled from oppression in Europe, they flamed with the spirit of the real liberty lover when in contact with the Prussian.

A little group of the 111th's ambulanciers when carrying back the wounded, met a German major who was groaning and complaining vigorously and demanding instant attention. The contrast between his conduct and that of American officers, who almost invariably told the litter-bearers to go on and pick up worse wounded men, was glaring, but finally the bearers good-humoredly decided to get the major out of the way to stop his noise. He was not wounded severely, but was unable to walk, and they lifted him to the stretcher with the same care they gave to all the wounded.
