Of the subsequent career of Coronado little is known, but he does not appear to have continued long in office, for in 1573 Diego de Artieda Cherino[XXIV‑14] entered into a contract with the crown to pacify and further colonize the provinces of Costa Rica, Nicaragua, and Nicoya, and was appointed governor and captain general of those territories. According to the terms of his contract the natives were to be taught the arts of peace, and those who should be christianized were to be exempt from tribute for ten years; commerce with the Indians was to be encouraged; agriculture, mining, and other industries were to be developed; no hostilities with the natives were to be permitted until overtures of peace had been thrice rejected; settlements were not to be founded in districts reserved for the use of Indians; the principal towns were to revert to the emperor; four ecclesiastics must accompany the expedition, two of them at least to be Jesuits. Finally, full reports of all important proceedings were to be forwarded from time to time to the crown.[XXIV‑15] [Sidenote: BUCCANEERS.] Cherino soon levied a force of two hundred men, but on account of the difficulty in procuring vessels, his Majesty having secured every available ship for a naval expedition to Flanders, it was not until the 15th of April 1575 that he took his departure, setting sail from the port of San Lúcar.[XXIV‑16] He was directed first to cruise off the coast in search of English buccaneers, who were then infesting those parts; but finding no sign of their presence he landed on the shore of Costa Rica near the mouth of a river to which he gave the name of Rio de Nuestra Señora del Valle del Guaini. Sailing up the stream for two or three leagues, he founded on its banks two settlements, to one of which he gave the name of Ciudad de Artieda del Nuevo Reyno de Navarra. In the presence of most of his men he took formal possession of the site; on a tree standing on the spot selected for the plaza he marked with a cutlass the sign of the cross "in the name of the Father, the Son, and the Holy Ghost;" he then addressed his followers,[XXIV‑17] telling them that all who desired might select town lots and secure all the privileges granted to settlers by the emperor. Captain Francisco Paron was then ordered by the governor to make further explorations, and ascending the river for a distance of nine leagues he discovered a fertile valley, and finding the natives tractable and well disposed, took possession with the usual formalities, naming it Valle de los Pufibais y del Valderroncal. Cherino does not appear to have been successful in founding any permanent settlements in Costa Rica; for we learn that in 1586 Cartago and Esparza were the only towns in the province inhabited by Spaniards,[XXIV‑18] and that they were constantly at war with the Indians.
