the planetoid, there was another standing rule. A law, this time; a duly enacted law of the Palladian legislature and the sole ordinance that was enforced by the foreign-sponsored native authorities. Before a visitor was admitted to Pallas, he was first made to post a bond equal to his passage back home. And that could not be touched or refunded until he left. MacCauley groaned aloud and looked about him. Walking blindly and without thinking, very easy in the light gravity of low-powered magna-gravs, he had entered a part of the sealed city new to him. He was in the native quarter, at the planetoid's core, where the asterites were as thick as red dust on Mars—and for the first time Mac saw a Kiddie policeman. He was wearing no more clothing than the rest of his kind, just carried a staff of office, like the old Bow Street Runners. An idea suddenly made contact in MacCauley's mind. He signaled the officer and dragged out a notebook and pencil, unnecessarily, as it happened. The Kiddie, in sinuous gestures, signified that he could understand English, partly by lip-reading, partly by picking up the sound in some weird fashion through rock-conduction and the sensitive soles of his splay feet. Mac, enunciating carefully, spoke. "One of your people has robbed me. I want him arrested. Where do I go?" The Kiddie bobbed his head, and from the manner in which his luminiferous glands sparkled balefully, it was evident where he thought MacCauley should go. Nevertheless, he snapped out his little pad and stylus, and scrawled: "Commi wih me tu Offic he wil arange arest." MacCauley deciphered the scribble. He shrugged and said, "Okay. Hop to it, sonny." He walked beside the diminutive policeman for a few hundred feet, glancing incuriously at the small burrows which pierced the rock walls and kicking away chunks of the queer, spongy rock on which the Kiddies subsisted, the equivalent of Earthly garbage. He should have thought of the cops before, he realized. The Kiddies, as a race, were not numerous, and he could probably bully them into finding the thief and recovering his money. After all, why not? He soon found out. The lolling half-breed Venusian interpreter who loafed around the ratty, worm-infested police station heard his complaint and deftly translated it for the benefit of a moth-eaten Kiddie who seemed to be as much in charge here
