CHAPTER VThe spider ships towered above the surrounding aircraft. Their construction was utilitarian; their living quarters were cramped; entrance was achieved from the ground by means of a retractable ladder from the base platform. The underbelly dome contained the cutting ray. It could strike deep into the Earth, burning through shale and granite with equal efficiency. The portable casing could be sunk almost simultaneously; it would seem to contain the ray as a hose contains water. While like a giant rig, the ship would poise on its triple legs above the operation. As rapidly as the crew could section the casing, the drilling would proceed. The three ships would form a triangle. Like insects sending down stingers they would, when the time came, lance three deep shafts into the Earth.
