CHAPTER II
THE WINGED MESSENGER
"What do you call this, Tom? A queer sort of crow, I'd say. Looks more to me like the blue-rock pigeons Sam Becker used to raise at home," and so saying Jack held up the still quivering bunch of feathers.
Tom took one quick look, and then a startled expression flitted across his face.
"Just what it is, Jack!" he hastened to say. "A homing pigeon in the bargain! You can tell that from the bill and the ring around the eyes."
Jack in turn became aroused.
"A homing pigeon, is it?" he ejaculated. "Why, birds like that are used for carrying messages across the lines! Some of our airplane pilots have told me that sometimes they take a French spy far back of the German front. When he had made an important discovery he would write a message in cipher, enclose it in a tiny waterproof capsule attached to a ring about the pigeon's leg, and set the bird free. Inside of half an hour it would be safe back in its loft, and the message on the way to French headquarters."
