By the mail which carries the "Memorial" are sent various letters supplementing the information contained in that document, or commending the envoy, Father Sánchez. The military officials write to the king (June 24), reminding him that the foothold gained in the islands by the Christian faith can be maintained only by the presence of troops there. The soldiers (whose courage and loyalty in the past are praised) are discouraged, because they have not received the rewards which they expected; they are lawless and demoralized, and their officers cannot control them. The defense of Manila is thus imperiled, and the natives are led to despise the Spaniards. The officers who write this letter complain because they have been unjustly treated in their efforts to improve this condition of affairs; they ask for redress, and for the abolition of the royal Audiencia. A letter from the cabildo (municipal council) of Manila commends Sánchez as their envoy to the king. They complain that the Audiencia "cannot be maintained here without the total destruction of the state," which cannot bear the burden of this expense; and ask that it be abolished. They ask for a garrison of three hundred paid troops, and the grant of an encomienda to the city of Manila. They complain of the losses inflicted not only upon the merchants of that city, but upon the colonial government, by the trade which Mexican merchants carry on through the port of Manila with the Chinese; and demand that this traffic be restricted to the citizens of the islands. They ask the king to see that more friars be sent out, both Augustinians and Franciscans. The cabildo recommend that the archdeacon Juan de Bivero receive from the king some reward for his hitherto unrecompensed services in the Philippines. On the same day Antonio Sedeño, rector of the Jesuits at Manila, writes a letter commending Sánchez for this present embassy, and recounting his past services to the Philippine colony. On June 26 Bishop Salazar writes a short letter, regarding some points outside of Sanchez's commission. One of these concerns the respective precedence of the bishop and the Audiencia on public occasions. The bishop also describes the quarrels between the president and auditors of the Audiencia, and his success in reconciling these differences. He has delivered, although against his better judgment, certain prisoners to the Inquisition, in obedience to a royal decree. A letter from the Audiencia of the Philippines to the king (dated June 26), recommends an increase in the rate of tribute paid by the Indians; the money thus obtained could be used to pay the soldiers, which would greatly improve the standard of military service in the islands. The colonial treasury is greatly embarrassed by heavy expenses, and the salaries of the Audiencia would better be paid from Mexico; then the encomiendas of Indians now taxed for that expense could be assigned to the soldiers
