But even with these new, soft laws, herds must be guarded--especially with that null expanding as it was. Even some lackland idiot should be able to understand that much. He turned his attention to the headman's hut. The man was there. Surrounded by a few villagers, he squatted before his flimsy, frond-roofed hut, his mouth in grotesque motion. Now, he stopped his noisemaking and poised his head. Then he nodded, looking about the village. Obviously, he was taking his ease and allowing his people to do as they would, without supervision. Barra started to concentrate on the surrogate, to make his wishes and his displeasure known. Then he turned impatiently from the crystal, seizing his staff. Efficient as the surrogates were, there were some things better attended to in person. * * * * * He got to his feet and strode angrily out of the study, sending a peremptory summons before him. As he entered the wide hallway, an elderly slave came toward him. Barra looked at the man imperiously. "My cloak," he demanded, "and the cap of power." He projected the image of his fiber cloak and of the heavy gold headpiece with its precisely positioned crystals, being careful to note the red, green and blue glow of the various jewels. Meticulously, he filled in details of the gracefully formed filigree which formed mounts to support the glowing spheres. And he indicated the padded headpiece with its incrustation of crystal carbon, so his servitor could make no mistake. The man was more sensitive than one of the village slaves, but even so, he was merely a pseudoman and had to have things carefully delineated for him. As the man walked toward a closet, Barra looked after him unhappily. The heavy power and control circlet was unnecessary in the Residence, for amplifiers installed in the building took care of all requirements. But outside, in the village and fields, a portable source of power and control was indispensable and this heavy gold cap was the best device he had been able to find. Even so, he hated to wear the circlet. The massive crystals mounted on their supporting points weighed a couple of pounds by themselves and though the gold insulating supports were designed as finely as possible, the metal was still massive and heavy. It was a definite strain on his neck muscles to wear the thing and he always got a headache from it. For an instant, envy of the powerful psionics crossed his mind. There were, he knew, those who required no control or power devices, being able to govern and direct psionic forces without aid. But his powers, though effective as any, required amplification and when he went out of the Residence it was essential that he have the cap with him. Proper and forceful handling of the things of the Estates, both animate and inanimate, demanded considerable psionic power and this made the large red power crystal at the center of his cap most necessary.
