system of tribute, the regulations for preserving game and for forest conservancy, and the administrative details. Here and there he points out a way in which the legislation of the Incas might be imitated and utilized by their conquerors.[1235] Agustin de Zarate, though a lawyer by profession, had been employed for some years in the financial department of the Spanish government before he went out to Peru with the Viceroy Blasco Nuñez to examine into the accounts of the colony. On his return to Spain he was entrusted with a similar mission in Flanders. His _Provincìa del Peru_ was first published at Antwerp in 1555.[1236] Unacquainted with the native languages, and ignorant of the true significance of much that he was told, Zarate was yet a shrewd observer, and his evidence is valuable as regards what came under his own immediate observation. He gives one of the best descriptions of the Inca roads. The _Relacion_ of Fernando de Santillan is a work which may be classed with the reports of Polo de Ondegardo, and its author had equal advantages in collecting information. Going out to Peru as one of the judges of the Audiencia in 1550,[1237] Santillan was for a short time at the head of the government, after the death of the Viceroy Mendoza, and he took the field to suppress the rebellion of Giron. He afterwards served in Chile and at Quito, where he was commissioned to establish the court of justice. Returning to Spain, he took orders, and was appointed Bishop of the La Plata, but died at Lima, on his way to his distant see, in 1576. The _Relacion_ of Santillan remained in manuscript, in the library of the Escurial, until it was edited by Don Márcos Jiménez de la Espada in 1879. This report appears to have been prepared in obedience to a decree desiring the judges of Lima to examine aged and learned Indians regarding the administrative system of the Incas. The report of Santillan is mainly devoted to a discussion of the laws and customs relating to the collection of tribute. He bears testimony to the excellence of the Inca government, and to the wretched condition to which the country had since been reduced by Spanish misrule. The work of the Licentiate Juan de Matienzo, a contemporary of Ondegardo, entitled _Gobierno de el Peru_, is still in manuscript. Like Santillan and Ondegardo, Matienzo discusses the ancient institutions with a view to the organization of the best possible system under Spanish rule.[1238] Melchor Bravo de Saravia, another judge of the Royal Audience at Lima, and a contemporary of Santillan, is said to have written a work on the antiquities of Peru; but it is either lost or has not yet been placed within reach of the student. It is referred to by Velasco. Cieza de Leon mentions, at the end of his Second Part, that his own work had been perused by the learned judges Hernando de Santillan and Bravo de Saravia.
