"Wonder--probably good for something. Well, we're as close as we can go, all of us standing with our heads pointing at the planet and held to the floor of our project by centrifugal force caused by the planet's rotation. We won't stay long. None of us can stand the mental strain of looking out of the window and seeing solid ground a few feet above our heads and a million million miles of sky to fall down into if we step out of the door. _Brrrrr._" "Close the sun proof shutters and don't look," suggested Billy. "I'm taking a nice large bromide to chill off a few screaming nerves and then I am going out and take me a shovelful of that dirt and rock up there. Gosh, it's going to feel funny digging _down_ something that wants to rise. Let's make it quick." Billy emerged from the lock completely clad in spacesuit. He took air samples, and then, with the catch-knob between his shoulder blades firmly in the focal sphere of a tractor-pressor beam, Billy was shoved up to the surface of the planet. Reaching up over his head, Billy pulled down a few stones and dropped them upward into the bucket he held inverted. They fell upward to the surface of the planet, and the bucket was held by their weight. They never did know whether there were any Eurekans, but if there were, and the Terrans were watched, it was a strange sight they saw. A sixty-foot rectangular building of steel, one story high, resting upside down with the planet-side to the sky. Projectors dug into the ground, pulled by the anchoring tractors that pulled the upside-down building even tighter to their planet. From a spacedoor, a pale green beam was fastened to the knob on the creature's back. He was head down, suspended on the beam, and carrying a bucket that must have been filled with antigravity material for the bail was free and the bucket actually hung upward! The creature was lowered, still head down, to the surface of Eureka. He reached down below his head and lifted a few stones, dropping them into the bucket, which he held right-side up. Naturally the bucket dropped properly enough to the ground. Working by digging down, Billy filled the bucket and was returned down to the door. "Cut 'em!" he said hoarsely. They cut the anchors and the project was thrown from the surface of Eureka by centrifugal force. And as they left Eureka, and headed for the Sun, they held a council and decided that another attempt--blind though it would be--to warp space would be in order. XX. "Get every recording gadget we've got on the thing," said Billy. "Maybe we can find out something that will give us a directional trend. And anybody who thinks he won't be struck by lightning if he makes a prayer, go to it. We could use a bit of Divine Assistance."
