8. There has always been an outcry in España against the purchase of public offices in the Yndias, notwithstanding that these have been placed on sale only in the exigencies of the crown. If the sale of these offices on the royal account is a question involving much scruple, it necessarily follows that it would be an injustice to sell them on the account of those who have authority to make appointments to those offices ad interim. Consequently, by reëstablishing the oldtime method--by which the candidates for the posts of alcalde must present themselves before the royal Audiencia with documentary evidence of their merits, in order that three qualified persons might be presented to the superior government, in the first, second, and third places respectively, for each post of alcalde--the dangers arising from the sale of offices which has been practiced in some governments would be avoided; and the selection [of officials] would be more conformable to justice and less mercenary (as I represented to his Majesty in the year 760). The royal exchequer could thus save the salaries of the alcaldes and magistrates (as is done in Nueva España), which saving would amount, as in the second item of statement iii, to the sum of seven thousand, five hundred pesos. (If the alcaldeships were knocked down to the highest bidder in the auction-hall, together with the farming of the tributes, it would result in even greater profit to the royal exchequer.) 9. The offices of commander and military officers of the ship which goes annually to Acapulco are bestowed on citizens of this city; and the appointments to these offices can be made without giving them the salaries which hitherto they have enjoyed; for they are sought not so much for the salaries as for the honor, and for the free passage, with comfortable berths and conveniences, [which is furnished to officers]. Consequently the royal exchequer could save the amount of the said salaries, which exceeds ten thousand pesos. 10. In the paper of suggestions and the report which I cited in the first item of statement v, are mentioned the many advantages which would result from the establishment of guilds [gremios] which I propose; and from the increase of the royal revenues by the half-annats from the officials [of the crown]; and by the duties of one-fifth on silver and gold. These metals are wrought, at the will of the silver-smiths, of various standards and degrees of purity, contrary to the provisions of the royal decree of March 17, 1735; and as I cannot fix the exact amount for the aforesaid duties, a moderate estimate is made, at the lowest [standard], that the increase of the royal revenue would amount to some seven thousand pesos.
