“Okay.” Gale could hear Jan moving along the ledge above.
Keeping her eyes on the dwarf pines as much as possible, Gale dragged a tangled mass of electric wire from the mass of rocks. After untangling this, she wound it round and round the radar set.
“There,” she breathed. “Now I can attach it to the cable and Jan can draw it up.”
“Here it comes,” Jan called a moment later as the twisted cable came gliding down the rocky wall.
In a twinkle Gale had the cable attached to the radar set and was watching it go up.
Strangely enough, at that moment she was seized with a sense of wild panic. It was only by exerting all her will power that she avoided ordering Jan to let the radar set down so she could go up instead. Little wonder, for she had been through much that day.
And then she heard it again,—that strange scraping on rock that was like shuffling footsteps, but not quite. Instantly her eyes were on the dwarf pines. Did she get a fleeting glimpse of a face and gleaming eyes? She could not be sure.
“In case of doubt, act!” had been her father’s motto. She acted now. Aiming low, she fired two shots. Bang! Bang! To her startled ears, the shots echoing in the cavern seemed like cannon fire.
There followed a sound of commotion behind the pines. Then all was silence.
Out of that silence came Jan’s voice.
