Much correspondence of various kinds might be cited to show that the governor was encouraged to consult the audiencia on Chinese affairs. Not only was the governor expected to do this, but the king himself directed many letters to the "governor and audiencia" and to the "governor and oidores," in which he asked for advice and information bearing upon Chinese affairs. As we have already seen, cédulas treating of these matters were frequently expedited to the "governor and audiencia." The audiencia was requested by the royal authority on August 8, 1609, to submit information as to the truth of various statements by persons in the Islands that the Chinese were carrying away vast quantities of silver. The audiencia was ordered to enact measures which would stop this abuse, which, if persisted in, would inevitably result in an impoverishment of the Philippine community and government. The oidores were asked to suggest a course of action which would result in the retention of the Chinese trade and at the same time prevent the Chinese from doing irreparable damage to the royal exchequer in the ways alluded to. [507] In further illustration of the same subject, we may note the instructions of the king to Governor Silva, dated March 27, 1616. On this occasion the king prescribed a course of action for the governor to follow in case of the invasion of the Islands by the Chinese and Japanese. He was especially directed to prevent a union of the Chinese in the Parián with the forces of the expected invaders. Silva was ordered to take no steps without first consulting the oidores. [508] On July 25, 1619, having received news of the insubordination of the Chinese in Manila and of the danger of a revolt among them, the king wrote to the "president and oidores" expressing the belief that too many Chinese had been admitted to the Islands and that thereafter only enough should be permitted to man the ships and carry on trade. [509] The authorities to whom this letter was directed were charged not to allow the royal will relative to this matter to be disregarded, which, of course, implied the exercise of an executive power on the part of the magistrates, in addition to consultative authority.
