“Now wait a leetle,” Blinkey Bill began to hedge. “I ain’t plumb sure fer sartin that—”

Just then the most dazzling flash of all zig-zagged its way across the blue-black sky. It was followed at once by a terrific roar.

“Here! Here!” Blinkey Bill’s voice trembled so he could scarcely speak. “Here! Gimme that air paper. Hit’s proper to sign hit, plumb proper.”

The Kentucky football star had been having a little practice. If one were to judge by his action it might be proper to say that Nicodemus had enjoyed this nocturnal adventure quite as much as the boy.

The line carries power to a coal mine. Hope they don’t arrest me for stealing power. Guess they won’t if I tell my story.
