A Case of Conscience

From the oval front window of the house to which Qeaver and Ruiz-Sanchez had been assigned, the land slanted away with insidious gentleness toward the ill-defined south edge of Lower Bay , a part of the Gulf of Sfath . Most of the area was salt marsh, as was the seaside nearly everywhere on Lithia. When the tide was in, the flats were covered to a depth of a yard or so almost half the way to the house. When it was out, as it was tonight, the jungle symphony was augmented by the agonized barking of a species of lungfish, sometimes as many as a score of them at once. Occasionally, when the small moon was unoccluded and the light from the city was unusually bright, one could see the leaping shadow of some amphibian, or the sinuously advancing sigmoid track of the Lithian crocodile, in pursuit of some prey faster than itself but which it would nonetheless capture in its own geological good time.

Still farther — and usually invisible even in daytime because of the pervasive mists — was the opposite shore of Lower Bay, beginning with tidal flats again, and then more jungle, which ran unbroken thereafter for hundreds of miles north to the equatorial sea.

Behind the house, visible from the sleeping room, was the rest of the city, Xoredeshch Sfath, capital of the great southern continent. As was the case in all the cities the Lithians built, its most striking characteristic to an Earthman was that it hardly seemed to be there at all. The Lithian houses were low, and made of the earth which had been dug from their foundations, so that they tended to fade into the soil even to a trained observer.

Most of the older buildings were rectangular, put together without mortar or rammed-earth blocks. Over the course of decades the blocks continued to pack and settle themselves until it became easier to abandon an unwanted building than to tear it down. One of the first setbacks the Earthmen had suffered on Lithia had come about through Agronski's ill-advised offer to raze one such structure with TDX; this was a gravity-polarized explosive, unknown to the Lithians, which had the property of exploding in a flat plane which could cut through steel girders as if they were cheese. The warehouse in question, however, was large, thick-walled, and three Lithian centuries old — 312 years by Earth time. The explosion created an uproar which greatly distressed the Lithians, but when it was over, the storehouse still stood, unshaken.

Newer structures were more conspicuous when the sun was out, for just during the past half-century the Lithians had begun to apply their enormous knowledge of ceramics to house construction. The new houses assumed thousands of fantastic, quasi-biological shapes, not quite amorphous but not quite resembling any form in experience, either; they looked a little like the dream constructions once made by an Earth painter named Dali out of such materials as boiled beans. Each one was unique and to the choice of its owner, yet all markedly shared the character of the community and the earth from which they sprang. These houses, too, would have blended well with the background of soil and jungle, except that most of them were glazed and so shone blindingly for brief moments on sunny days, when the light and the angle of observation were just right. These shifting coruscations, seen from the air, had been the Earthmen's first clue as to where the intelligent life was hiding in the ubiquitous Lithian jungle. (There had never been any doubt that there was intelligent life there; the tremendous radio pulses emanating from the planet had made that much plain from afar.)

Ruiz-Sanchez looked out through the sleeping-room window at the city, for at least the ten thousandth time, on his way to Cleaver's hammock. Xoredeshch Sfath was alive to him; it never looked the same twice. He found it singularly beautiful. And singularly strange: though the cities of Earth were very various, none was like this.

He checked Cleaver's pulse and respiration. Both were fast, even for Lithia, where a high partial pressure of carbon dioxide raised the pH of the blood of Earthmen and stimulated the breathing reflex. The priest judged, however, that Cleaver was in little danger as long as his actual oxygen utilization was not increased. At the moment he was certainly sleeping deeply — if not very restfully — and it would do no harm to leave him alone for a little while.

Of course, if a wild allosaur blundered into the city.… But that was just about as likely as the blundering of an untended elephant into the heart of New Delhi . It could happen, but it almost never did. And no other dangerous Lithian animal could break into the house if it was closed. Even the rats — of the abundant monotreme creatures which were Lithia's equivalent — found it impossible to infest a pottery house.
