"Yes, that's always the trouble, when you go out after rabbits and haven't any hound along to get them up and bring them within gunshot," grumbled Jack.

"But we've had a good walk," returned his companion; "and for a time we managed to get away from that terrible explosion of shells, and big-gun firing. We ought to be thankful for our little time off, Jack."

"Oh! I'm not really complaining," remarked the other young aviator, with a whimsical expression on his good-natured face. "But don't you know I hate to go back without having fired even one shot." He stopped short and pointed upward. "Hold on, Tom; there's some kind of bird going to pass over right now! Crow or anything, please bring it down! I'll promise to eat it, no matter what it is."

Laughingly Tom threw the gun up to his shoulder, and the next instant the report sounded. It seemed almost contemptible, after listening to the roar of those monster shells exploding for so long.

The bird fell fluttering in a heap. Tom evidently was a fair marksman, for it had been moving swiftly over their heads at the time he fired. Jack ran forward and picked the game up. As he did so he gave utterance to exclamations that naturally excited the curiosity of his chum. So Tom, after reloading his gun with a fresh shell, waited for Jack to rejoin him, which the other did, his face full of mystery.


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."
