"Why, where do you think we are?"

"I don't know. Might be Serbia, might be Greece, might be Bulgaria, or Turkey or any old place. If the elevating apparatus on our plane was out of whack, the steering apparatus may have been, too. Also I have mislaid my compass. I won't know north from south until morning."

"Hm-m-m," muttered the colonel. "Well, shall we try this house?"

"May as well, I guess," said Chester.

He led the way to the front door and rapped sharply with his knuckles.

There was a sound of some one stirring within, but no face appeared at the door in response to the lad's knock. He rapped sharply again. This time there was not a sound from within.

Chester walked a little ways from the house and glanced at the window through which a light had been visible a few moments before. It was perfectly dark now. Apparently the light had been extinguished the moment he had rapped on the door. All was dark within.

Chester moved toward the house again, thinking to rap on the door once more. As he did so, there came the sound of a shot and Chester felt something whistle by his ear.

"Wow!" he cried, and dashed toward the door where Colonel Anderson and
Ivan stood.

"Hit?" cried Colonel Anderson, as the lad dashed up.
