3d.  And inasmuch as I am not confident that the viceroy will be willing to admit that the appointments of offices and officials of these ships from these islands do not concern him, when those who are appointed complete the exercise of their duties on their arrival at Nueva Espana—­as, for instance, Don Francisco de la Serna, who is going this year as commander; and Don Luis Fernandez de Cordova, who was commander last year, as they commenced to exercise those offices from the time of their departure from those provinces and are returning in those functions through courtesy, and for just considerations—­the viceroy undertakes to appoint men to those places, refusing to understand as he ought what your Majesty has ruled and ordered in this matter.  On the contrary, in order to establish himself in this pretension, he has suppressed the appointments that I sent last year.  Indeed, although he deprived Don Fernando de Ayala of his appointment, he did not make another appointment, but said that he was satisfied for that time with that act of jurisdiction.  He said that he would send me another as commander of the ships—­a young man, like those whom he sends as captains of infantry.  That would have resulted in the disinclination of people in this country to send what is of so much importance [i.e., their cargoes to Nueva Espana], with the supplies and artillery which I sent—­very differently from the usual practice, in charge of a man of action and valor, who has fought very often.  I cannot see why the viceroy should wonder at a thoroughly satisfactory person being appointed and sent from here, in order to return in such a post, since for a matter of so great consideration, value, and importance, it does not seem much or hurtful that each ship should always have a captain, like those whom your Majesty appoints in the flagships and almirantas of the trading-fleets, with the same preeminences and the right of succession to the responsibility and management of them, in case of the death or absence of their commanders.  For it would be a misfortune, in case of their absence, for the relief or the ruin of these islands to depend, on the occasion of a fight or other emergency in which there is need of a leader, on the direction of a pilot or a master, when suitable provision can be made without any considerable increase of expense to your royal treasury.  If your Majesty be so pleased, and will give me authority for it, I prefer to do this, even if, in order to give them some pay, that of the commanders and officials be curtailed; or by seeking another plan and supplying them something with certain accommodations in their vessels, as might be done better here.  The men levied in Mexico and those provinces might be delivered at Acapulco to those captains, thus saving the pay granted to the infantry captains and officers.  For most of the latter are not usually very eager in their service, while their persons and the troubles that they bring are of no little embarrassment to
