vanished, too, into the uniform green of the uninhabited Fifth Level.  A planet could take pretty good care of itself, he thought, if people would only leave it alone.  Then he began to see the fields and villages of Fourth Level.  Cities appeared and vanished, growing higher and vaster as they went across the more civilized Third Level.  One was under air attack—­there was almost never a paratemporal transposition which did not run through some scene of battle.

He unbuckled his belt and took off his boots and tunic; all around him, the others were doing the same.  Sleep-gas didn’t have to be breathed; it could enter the nervous system by any orifice or lesion, even a pore or a scratch.  A spacesuit was the only protection.  One of the detectives helped him on with his metal and plastic armor; before sealing his gauntlets, he reciprocated the assistance, then checked the needler and blaster and the long batonlike ultrasonic paralyzer on his belt and made sure that the radio and sound-phones in his helmet were working.  He hoped that the frantic efforts to gather several thousand spacesuits onto Police Terminal from the Industrial and Commercial and Interplanetary Sectors hadn’t started rumors which had gotten to the ears of some of the Organization’s ubiquitous agents.

The country below was already turning to the parched browns and yellows of the Abzar Sector.  There was not another of the conveyers in sight, but electronic and mechanical lag in the individual controls and even the distance-difference between them and the central radio control would have prevented them from going into transposition at the same fractional microsecond.  The recon-details began piling into their cars.  Then the red light overhead winked to green, and the dome flickered and solidified into cold, inert metal.  The screens lighted up again, and Vall could see Skordran Kirv, across Asia and the Pacific, getting into his helmet.  A dot of light in the center of the underview screen widened as the mesh under the conveyer irised open around the pickup.

Below, the Organization base—­big rectangles of fenced slave pens, with metal barracks inside; the huge circle of the Kholghoor Sector conveyer-head building, and a smaller structure that must house conveyers to other Abzar Sector time lines; the work-shops and living quarters and hangars and warehouses and docks—­was wreathed in white-green mist.  The ring of conveyers at three thousand feet were opening and spewing out aircars and airboats, farther away, the greater ring of heavy conveyers were unloading armored and shielded combat-craft.  An aircar which must have been above the reach of the gas was streaking away toward the west, with three police cars after it.  As he watched, the air around it fairly sizzled blue with the rays of neutron disruption blasters, and then it blew apart.  The three police cars turned and came back more slowly.  The three-thousand-ton passenger ship which had been hastily fitted with armament was circling about; the great dock conveyer which had brought it was gone, transposed back to Police Terminal to pick up another ship.
