ion-beam ships circling about Le Beau Pays. All succumbed to the Philosophy of the Natural. Within a few generations a stranger landing upon the planet would not have known without previous information that the Terrans were not aboriginal. He would have found three species. Two were warm-blooded egglayers who had evolved directly from reptiles without becoming mammals--the Ssassarors and the Amphibs. Somewhere in their dim past--like all happy nations, they had no history--they had set up their society and been very satisfied with it since. It was a peaceful quiet world, largely peasant, where nobody had to scratch for a living and where a superb manipulation of biological forces ensured very long lives, no disease, and a social lubrication that left little to desire--from their viewpoint, anyway. The government was, nominally, a monarchy. The Kings were elected by the people and were a different species than the group each ruled. Ssassaror ruled Human, and vice versa, each assisted by foster-brothers and sisters of the race over which they reigned. These were the so-called Dukes and Duchesses. The Chamber of Deputies—L'Syawp t' Tapfuti—was half Human and half Ssassaror. The so-called Kings took turns presiding over the Chamber for forty day intervals. The Deputies were elected for ten-year terms by constituents who could not be deceived about their representatives' purposes because of the sensitive Skins which allowed them to determine their true feelings and worth.In one custom alone did the ex-Terrans differ from their neighbors. This was in carrying arms. In the beginning, the Ssassaror had allowed the Men to wear their short rapiers, so they would feel safe even though in the midst of aliens. As time went on, only the King's mucketeers--and members of the official underground--were allowed to carry épées. These men, it might be noticed, were the congenital adventurers, men who needed to swashbuckle and revel in the name of individualist. Like the egg-stealers, they needed an institution in which they could work off anti-social steam. From the beginning the Amphibians had been a little separate from the Ssassaror and when the Earthmen came they did not get any more neighborly. Nevertheless, they preserved excellent relations and they, too, participated in the Changeling-custom. This Changeling-custom was another social device set up millennia ago to keep a mutual understanding between all species on the planet. It was a peculiar institution, one that
