The Arrillians had learned English easily, its basic sounds not being too alien to their own tongue. They had quite a city there on the edge of the jungle, although, in circling the planet before landing, the expedition had noted that this was the only city. On a world only a little smaller than Earth, one city, surrounded completely by the tropical jungle which covered the rest of the world. A city without power, without machinery of any kind, and yet a city that was self-sufficient. Well-tilled fields stretched to the very edge of the jungle, where high walls kept out the voracious growth. The fields fed the city well, and clothed it well. And there were mines to yield up fine metal and precious gems. The Earthmen had marveled, and yet, it had seemed strange. On all this planet, just one city with perhaps half a million people within its walls. But this was not a problem for the expedition. The crew of the _Polaris_ and the members of the expedition had spent many an enjoyable evening in the dining hall of the palace-like home of the Rhal, who was something more than a mayor and something less than a king. Actually, Arrill seemed to get along with a minimum of government. All in all, the Earthmen had summed up the Arrillians as being a naive, mild, and courteous people. They probably still thought so, all of them, that is, except Tyndall. Of course, now that he looked back upon it, there has been a few things ... that business about the Bugs, as the Earthmen had dubbed the oddly ugly creatures who seemed to occupy something of the position of a sacred cow in the Arrillian scheme of things. The Bugs came in all sizes, that is all sizes from a foot or so in length up to the size of a full human. The Bugs were not permitted to roam the streets and market places, like the sacred cows of the Earthly Hindus. The Bugs were kept in huge pens, which none but a few high-ranking priests were permitted to enter, and although the Earthmen were not prevented from standing outside the pens and watching the ugly beasts munching grass or basking in the sun, the Arrillians always seemed nervous when the strangers were about the pens. The Earthmen had shrugged and reflected that religion was a complexity difficult enough at home, needless to probe too deeply into the Arrillian. But The Time had been something else again, bringing with it, the first sign of real Arrillian fanaticism and the first hint of violence. Tyndall and four companions were strolling in a downtown section of the city, when all at once a hoarse cry in Arrillian shattered the quiet hum of street activity. "What did he say?" asked one of Tyndall's companions, who had not learned much Arrillian.
