“Not a thing,” rejoined Harry; “that means they must have a light in sight.”
“Still, I should like to know just where they are. Send them a flash.”
Harry bent over the wireless key and sent a message crackling into the night:
“Send up a flare.”
The answer soon came. From far below them a blue illumination lit up the trees and along a stretch of road in a lurid glare. The amused young aviators could see horses and cattle out at pasture in the quiet fields galloping for dear life at the alarming apparition.
“Can you see any sign of the others?” asked Frank, some minutes later.
Both boys had in the interval been peering anxiously ahead into the night.
“Not a sign, can you?”
“Not yet.”
“We ought to catch sight of them soon.”
