"That's great news!" cried Jack. "Then it paid to bring down that pigeon, didn't it?"
"It sure did, Jack!"
Two days later came a most important announcement, especially to the American airmen.
"Things are coming our way at last," the valiant commander announced, as they crowded about him. "The papers this morning say that Uncle Sam has at last got his back up. Any day may now bring the glorious news from across the Atlantic, telling that the United States has taken the steps that will put her in this World War against the Central Powers. Then it will be all over but the shouting."
"That's right!" cried Jack.
"You just leave it to Uncle Sam to do it!" added Tom.
Many more adventures were in store for the young aviators, and what some of them were will be related in the next volume of this series, to be entitled "Air Service Boys Over the Rhine; Or, Fighting Above the Clouds."
And here for the present let us leave the air service boys and say good-bye.
THE END
