"And either a woman or a girl, at that!" hazarded his chum in bewilderment.
"It might have been a boy," suggested Tom. "There it is again."
Both of them listened. Peculiar sensations crept over them as they stood and thus strained their ears to catch any further sounds. Sobbing at any time is enough to arouse the feelings of a sensitive nature; but heard in the dead of night, and under the conditions that surrounded the two young aviators, made it all the more thrilling.
Jack in particular was touched to the heart.
"Say, that's a queer thing, Tom!" he muttered. "Why should anybody be crying or screaming like that away off here, and at this time of night?"
"Oh, there are many who are weeping in these dark days," said Tom gravely. "The men in myriads of families will never come home again. Perhaps a mother, or it may be a sister, has just had word that son, father, or brother has been shot down in battle."
Jack shuddered. Why should his thoughts instantly fly to the Boche pilot whom they had met and fought and conquered while on the way to Metz on their present perilous mission? It had been a fair fight, and a case of their lives or his. Nevertheless Jack shuddered as he remembered how the other had gone down after that last exchange of gunfire.
"Tom, notice that it comes from almost the identical direction where I told you I heard the crowing of a rooster a while ago," he hastened to say, more to rid his mind of those ghastly thoughts than anything else.
What a strange fatality if this should be the home of the unfortunate Teuton pilot of that Fokker machine, and the one who mourned was his mother or a young sister, or perhaps his wife!
"That means there's a house not far away, possibly an estate of some kind," mused Tom, as though turning over some sudden project in his mind.
