"Glad you're all right, old girl," he said, running his fingers over the strings. "But I guess you're through for one night."

"Yes," chuckled Tom, as he started to unlace his shoes. "The Huns have given us their idea of a moonlight serenade!"

CHAPTER XIX

NICK RABIG UNDER ARREST

It might have been expected that a sleepless night would have followed the raid. But the young Americans were far too healthy and their nerves were already becoming too well steeled to let the Germans, like Macbeth, "murder sleep." Their eyes closed almost as soon as their heads touched the pillows, not to open again until reveille sounded the next morning.

They were a little more subdued than usual, however, as they dressed, for there was poor Fred's empty cot and some dark red blotches on the floor to remind them of their comrade's plight and their own narrow escape.

"I wonder how Fred's getting along," said Tom, voicing the general thought.

"All right, I hope," returned Frank. "It will make him sore to be cooped up now with a broken leg, just when the boys are putting the finishing touches on their training."

They were relieved to find on inquiry after breakfast, that Fred was doing finely, that the wound in his head was negligible and that the break in his leg was a simple fracture so that in six weeks he would probably be as well as ever.
