“Frank! Frank! Come here, quick!” he shouted.

The other, who had been thrusting his head out of the window of the hangar, immediately made a break for the door. Doubtless he half expected to see his cousin wrestling with some daring intruder, whom he had caught in the act of setting fire to the shed or some such caper.

“Where are you? What’s going on here?”

Calling in this strain Frank arrived in time to see Andy still on his hands and knees just as he had fallen. He seemed to be staring up at the starry heavens as though he had taken a sudden intense interest in the planets of the universe.

“Did you see anything?” he questioned, as he managed to clamber to his feet and clutch hold of the other.

“Not a thing!” came the ready reply; “but it seemed to me I heard shouts. And they seemed to be getting fainter and fainter, as if the fellows were running away.”

“That’s it, Frank, voices that sounded like they were sailing along overhead!” exclaimed Andy, excitedly.

“What’s that?” demanded the other, turning upon him; “overhead, you say? Ginger! Now that you mention it, seems to me there might be something in that. But how could anybody get above us, when there isn’t a single tree in this big field?”

“Frank,” Andy went on, earnestly, “I saw something just disappearing over yonder, where the woods begin to poke up in the east. And I give you my word that was where the voices came from!”

“Disappearing? Do you mean over the tree-tops, Andy?” cried the other, just as if the announcement he listened to nearly took his breath away.
