One wire, somewhat lighter in its insulation than the other, was wound around the heavier one. They traced it, as Sandy had done. It seemed to wind on down, as did others he showed, from each switch-pole, into the protective sheathing of metal and insulation; but none really were wound any further. From there on down, they ran behind the other wires!
“Bend down, close to the floor,” urged Sandy. “See all the dust and lint piled up?” He scraped some aside.
“My!” exclaimed Larry. “Golly-gracious-gosh-gravy-granny! The wires come out from behind the sheath and turn along the floor, close to the wall—and there’s dust all covering them! No wonder we didn’t notice them.”
“Where do they lead to?”
“Follow the dust line, Dick,” Sandy urged.
Back along the hangar wall they crept, until they came up to the small wooden cupboard with its dusty, frayed protecting burlap across the front. Under the cupboard boards the wires ran well concealed by more dusty lint which seemed to have been swept into the corners by the lazy act of some cleaner.
“Inside here—but don’t use a light—inside here, there are smaller duplicate switches for the electric light arc and the motors,” Sandy informed his breathless, admiring cronies.
They easily proved it. More, they located the wiring in the dusk.
“But how does Jeff get in and out of here?” asked Dick.
“We have to go outside so I can show you what I discovered.”
