This trade and commerce is so great and profitable, and easy to control--for it only lasts three months in the year, from the time of the arrival of the ships with their merchandise, until those vessels that go to Nueva Espana take that merchandise--that the Spaniards do not apply themselves to, or engage in, any other industry. Consequently, there is no husbandry or field-labor worthy of consideration. Neither do the Spaniards work the gold mines or placers, which are numerous. They do not engage in many other industries that they could turn to with great profit, if the Chinese trade should fail them. That trade has been very hurtful and prejudicial in this respect, as well as for the occupations and farm industries in which the natives used to engage. Now the latter are abandoning and forgetting those labors. Besides, there is the great harm and loss resulting from the immense amount of silver that passes annually by this way [of the trade], into the possession of infidels, which can never, by any way, return into the possession of the Spaniards. His Majesty's agents for the government and justice, and the royal officials for the management of his Majesty's revenue, are as follows: First, the governor and captain-general of all the islands, who is at the same time president of the royal Audiencia of Manila. He has a salary of eight thousand pesos de minas per year for all his offices. [243] He possesses his own body-guard of twelve halberdiers, whose captain receives three hundred pesos per year. The governor alone provides and regulates all that pertains to war and government, with the advice of the auditors of the Audiencia in difficult matters. He tries in the first instance the criminal cases of the regular soldiers, and any appeals from his decisions go to the Audiencia. [244] The governor appoints many alcaldes-mayor, corregidors, deputies, and other magistrates, throughout the islands and their provinces, for carrying on the government and justice, and for military matters. These appointments are made before a government chief scrivener appointed by his Majesty, who helps the governor.
