But it was soon discovered that the locality was unfavorable. It was hot, unhealthy on account of the neighboring swamps, and infested with mosquitoes and bats. The site was therefore removed to the plain of Huey Zacatlan,[XIII‑42] twelve leagues distant. Here were rich, arable, and pasture lands, while a winding river and numerous streams afforded an abundant supply of water. A town was formally laid out, lots were assigned to citizens, buildings begun, repartimientos granted, and the territory portioned in caballerias and peonias. It was afterward ordered at a session of the cabildo held on the 17th of August 1528, that all who desired to obtain land from the natives should do so by purchase. Protection was also extended to them by regulations framed to prevent the appropriation of their produce or its destruction by animals. Any Spaniard who sent his servant to gather maize from their fields was to forfeit ten pesos de oro for the first offence, and for the second to lose his servant, who was to be publicly flogged. Regulations passed during the early part of the following year required that all encomenderos should assemble the sons of the caciques at their residences to be instructed in the doctrines of the church. Christianized natives were to receive Christian burial, and others were to be decently interred outside the city. [Sidenote: RULE OF GUZMAN.] The administration of Mazariegos appears to have been based on humane principles and to have had in view the welfare of the settlers. But this condition of affairs was of brief duration. In 1529 Juan Enriquez de Guzman was ordered by the audiencia of Mexico to take his residencia, and appointed captain general and alcalde mayor of Chiapas. His investigation was conducted in a spirit of vindictiveness which can be accounted for only by the fact that the latter had previously been his juez de residencia. He stripped him and his friends of their repartimientos, and gave them to his own creatures; he appropriated his dwelling and town allotments, and when the man whom he thus despoiled soon afterward set forth for Mexico, gave further proof of his enmity by changing the name of the town to Villa Viciosa. By a royal cédula of July 7, 1536, its name was again changed to Ciudad Real.[XIII‑43]
