Very illustrious and reverend sir: Although I wrote for the city of Manila, the capital of the Philipinas islands, a memorial of one hundred and thirty-six sections--at the examination and discussion of which in the Council your illustrious Lordship was present--in regard to eighty-five petitions, to which can be reduced all the more important matters which may be presented concerning those islands and their trade-route and their maintenance; and that memorial with its petitions your illustrious Lordship is carrying with you, as it is printed, so that it seems as if there were no need of further information--and even these were superfluous to one who is so well informed on all the matters which he has in his keeping, and is so quick to understand those which may come before him: nevertheless, in order that I may to some extent relieve and set free your illustrious Lordship from the burdens imposed upon your memory, as I know the number and importance of the commissions that you must execute and the matters that you must decide in Nueva España (all which will be successfully accomplished, as we are assured by your wide experience in affairs), I have determined to comprise in this single treatise the matters which concern the city of Manila, and which it can present to you. It relates to the four leading points which were entrusted by his Majesty and the royal Council of the Indias, by royal decrees, to the judicious decision and accurate information of your Lordship, as follows: First, to what extent and in what manner shall the commerce of those islands be tarried on? Second, whether it will be expedient to increase and extend the permission which they at present enjoy, both in the export of merchandise and in the returns of money. Third, whether in the amount of merchandise allowed to them shall be included the products of the islands, or only those of China shall be understood. Fourth, whether the commerce which Perù was accustomed to hold with Nueva España shall be resumed, on account of the loss which results to the Philipinas and Nueva España from its suspension. Point first As for the first decree, which is so general as to include all, for treating of the commerce of the islands, which is essential to their preservation: this point, which in the memorial that I have cited is argued at length, can be reduced to an argument of three infallible propositions, of which, when two are proved, the third cannot be denied; and they are in this form.
