CHAPTER XVIII
A MYSTERY OF THE ETHER
Jessie knew that by carefully moving the slides on her tuning coil she could get into touch again with the talk to which she and Amy had been listening. But now the broadcasted cry for “Help!” seemed of so much importance that she wanted to hear more of this air mystery.

“For pity’s sake, Jess Norwood!” shrilled Amy. “Do you hear that?”
“I’m trying to,” her chum replied. “Hush!”
“It must be a hoax.”
“Wait!”
They listened and heard it repeated, almost word for word. A red barn and a silo and two fallen trees. These points the strange voice insisted on with each repetition.
