fissionables refinery at Jarnabar, spatially co-existent with the Fourth Level temple of Yat-Zar at Zurb. He was having a little trouble distinguishing between them, for every man wore the fringed blue robe and golden miter of an upper-priest, and had his face masked behind a blue false beard. It was, he admitted to himself, a most ludicrous-looking assemblage; one of the most ludicrous things about it was the fact that it would have inspired only pious awe in a Hulgun of the Fourth Level Proto-Aryan Sector. About half of them were priests from the Transtemporal Mining Corporation's temples; the other half were members of the Paratime Police. All of them wore, in addition to their temple knives, holstered sigma-ray needlers. Most of them carried ultrasonic paralyzers, eighteen-inch batonlike things with bulbous ends. Most of the Paratime Police and a few of the priests also carried either heat-ray pistols or neutron-disruption blasters; Verkan Vall wore one of the latter in a left-hand belt holster.

The Paratime Police were lined up separately for inspection, and Stranor Sleth, Tammand Drav of the Zurb temple, and several other high priests were checking the authenticity of their disguises. A little apart from the others, a Paratime Policeman, in high priest's robes and beard, had a square box slung in front of him; he was fiddling with knobs and buttons on it, practicing. A big idol of Yat-Zar, on antigravity, was floating slowly about the room in obedience to its remote controls, rising and lowering, turning about and pirouetting gracefully.

"Hey, Vall!" he called to his superior. "How's this?"

The idol rose about five feet, turned slowly in a half-circle, moved to the right a little, and then settled slowly toward the floor.

"Fine, fine, Horv," Verkan Vall told him, "but don't set it down on anything, or turn off the antigravity. There's enough collapsed nickel-plating on that thing to sink it a yard in soft ground."

"I don't know what the idea of that was," Brannad Klav, standing beside him, said. "Understand, I'm not criticizing. I haven't any right to, under the circumstances. But it seems to me that armoring that thing in collapsed nickel was an unnecessary precaution."

"Maybe it was," Verkan Vall agreed. "I sincerely hope so. But we can't take any chances. This operation has to be absolutely right. Ready, Tammand? All right; first detail into the conveyer."

He turned and strode toward a big dome of fine metallic mesh, thirty feet high and sixty in diameter, at the other end of the room. Tammand Drav, and his ten paratimer priests, and Brannad Klav, and ten Paratime Police, followed him in. One of the latter slid shut the door and locked it; Verkan Vall went to the control desk, at the center of the dome, and picked up a two-foot globe of the same fine metallic mesh, opening it and making some adjustments inside, then attaching an electric cord and closing it. He laid the globe on the floor near the desk and picked up the hand battery at the other end of the attached cord.

"Not taking any chances at all, are you?" Brannad Klav asked, watching this operation with interest.

"I never do, unnecessarily. There are too many necessary chances that have to be taken, in this work." Verkan Vall pressed the button on the hand battery. The globe on the floor flashed and vanished. "Yesterday, five paratimers were arrested. Any or all of them could have had door-activators with them. Stranor Sleth says they were not tortured, but that is a purely inferential statement. They may have been, and the use of the activator may have been extorted from one of them. So I want a look at the inside of that conveyer-chamber before we transpose into it."

He laid the hand battery, with the loose-dangling wire that had been left behind, on the desk, then lit a cigarette. The others gathered around, smoking and watching, careful to avoid the place from which the globe had vanished. Thirty minutes passed, and then, in a queer iridescence, the globe reappeared. Verkan Vall counted ten seconds and picked it up, taking it to the desk and opening it to remove a small square box. This he slid into a space under the desk and flipped a switch. Instantly, a view-screen lit up and a three-dimensional picture appeared—the interior of a big room a hundred feet square and some seventy in height. There was a big desk and a radio; tables, couches, chairs and an arms-rack full of weapons, and at one end, a remarkably clean sixty-foot circle on the concrete floor, outlined in faintly luminous red.

"How about it?" Verkan Vall asked Tammand Drav. "Anything wrong?"

The Zurb high priest shook his head. "Just as we left it," he said. "Nobody's been inside since we left."

One of the policemen took Verkan Vall's place at the control desk and threw the master switch, after checking the instruments. Immediately, the paratemporal-transposition field went on with a humming sound that mounted to a high scream, then settled to a steady drone. The mesh dome flickered with a cold iridescence and vanished, and they were looking into the interior of a great fissionables refinery plant, operated by paratimers on another First Level time-line. The structural details altered, from time-line to time-line, as they watched. Buildings appeared and vanished. Once, for a few seconds, they were inside a cool, insulated bubble in the midst of molten lead. Tammand Drav jerked a thumb at it, before it vanished.

"That always bothers me," he said. "Bad place for the field to go weak. I'm fussy as an old hen about inspection of the conveyer, on account of that."

"Don't blame you," Verkan Vall agreed. "Probably the cooling system of a breeder-pile."

They passed more swiftly, now, across the Second Level and the Third. Once they were in the midst of a huge land battle, with great tanklike vehicles spouting flame at one another. Another moment was spent in an air bombardment. On any time-line, this section of East Europe was a natural battleground. Once a great procession marched toward them, carrying red banners and huge pictures of a coarse-faced man with a black mustache—Verkan Vall recognized the environment as Fourth Level Europo-American Sector. Finally, as the transposition-rate slowed, they saw a clutter of miserable thatched huts, in the rear of a granite wall of a Fourth Level Hulgun temple of Yat-Zar—a temple not yet infiltrated by Transtemporal Mining Corporation agents. Finally, they were at their destination. The dome around them became visible, and an overhead green light flashed slowly on and off.

Verkan Vall opened the door and stepped outside, his needler drawn. The House of Yat-Zar was just as he had seen it in the picture photographed by the automatic reconnaissance-conveyer. The others crowded outside after him. One of the regular priests pulled off his miter and beard and went to the radio, putting on a headset. Verkan Vall and Tammand Drav snapped on the visiscreen, getting a view of the Holy of Holies outside.

There were six men there, seated at the upper-priests' banquet table, drinking from golden goblets. Five of them wore the black robes with green facings which marked them as priests of Muz-Azin; the sixth was an officer of the Chuldun archers, in gilded mail and helmet.

"Why, those are the sacred vessels of the temple!" Tammand Drav cried, scandalized. Then he laughed in self-ridicule. "I'm beginning to take this stuff seriously, myself; time I put in for a long vacation. I was actually shocked at the sacrilege!"

"Well, let's overtake the infidels in their sins," Verkan Vall said. "Paralyzers will be good enough."

He picked up one of the bulb-headed weapons, and unlocked the door. Tammand Drav and another of the priests of the Zurb temple following and the others crowding behind, they passed out through the veils, and burst into the Holy of Holies. Verkan Vall pointed the bulb of his paralyzer at the six seated men and pressed the button; other paralyzers came into action, and the whole sextet were knocked
