"Bah!" cried Kingston, turning on his heel. He left the office swearing eternal vengeance. An hour later, Majors came bursting into Pollard's office. "Pollard!" he exclaimed. "Listen! That wildman Kingston Galloway has just collected a gang of his cohorts, friends and buddies and they've all taken off like wildmen. They're heading for Wisconsin!" "The stupid idiot!" exploded Pollard, coming out of his chair. "Come on!" * * * * * Rhinegallis clasped Carroll's arm tightly as she stood beside him and looked at the almost-vibrant blackness that seemed to shimmer in the encircling wire mounted on the wall. Carroll was too busy to pay attention to her clasp. He was busy adjusting knobs on a haywire equipment on the bench beside him. The shimmering blackness flared briefly at one side, turned milky for an instant near the top--and then a pinprick of utter--nothingness--appeared to one side of the circle. Carroll adjusted knobs, brought the spot of sheer black into the center of the artificial plate and then expanded it. It was noticeable only because it--as a circle of utter no-response--was less energetic than the misty background. "That," he said, "is it." "The negative mass?" He nodded. "Is the 'fence' ready?" "Checked." "Now's as good a time as any," he said laconically. He left the vantage-point and went to another panel in the laboratory and began to throw switches. Five miles from Carroll's home a ten mile circle of wire came to life. Set on insulators mounted on trees in a rough circle, the area ten miles in diameter shimmered with a thin, misty film of energy--the same energy as that of the teleport. It thickened as Carroll adjusted the driving gear, thickened and became more positive until it was as shiningly opaque as the teleport screen-mirror. Trees in the circle, cut clean at the surface of the mirror fell, impelled by gravity into the screen. Then above the perfect plane of energy was nothing. The trimmed trees fell helter-skelter into a deep gorge from a smaller teleport plane twenty miles to the north. Then the perfect plane bowed downward into a shallow paraboloid of revolution. As it went down the up-thrusting trees were trimmed off and the matter in them converted into energy. A minute but perfect sphere appeared atop a pillar of energy not far from the rim of the paraboloid. Down went the center of the paraboloid, down into the bowels of the earth, and the sphere of stored energy grew rapidly. Down went the center, deep, until a perfect parabolic reflector ten miles in diameter and twelve miles deep resulted. The cubic mile after cubic mile of earth, rock, water, and forest were stored as energy in the sphere, now a full three feet in diameter.
