Most Excellent Sir: The predecessor of your Excellency, convinced of the important advantages to be derived by the Philippines, in making more intimate and more secure our few and doubtful relations with the island of Sulu, determined immediately upon assuming command, to negotiate with the Sultan of the said place, a treaty of peace and commerce which he considered, in every respect, not only useful but indispensable to the prosperity of the country. After having announced this project in various of his communications, he reported in December of last year, having accomplished the same, and furnished in several communications, an exact and detailed account of the history of his labors in the affair, the reasons which he had for undertaking the same, the benefits which he expects as results, and the measures whose adoption he deems necessary in order that these results may be more certain, and at the same time profitable. There were received from him seven letters, all marked with the letter “A,” numbered from 14 to 23, and dated from the 15th to the 29th of the said month; with so many points of analogy and similarity between them, that they should be considered as one only. The first, number 14, is intended to furnish information and data relative to Sulu, and the other Mohammedan islands of the south (without which it would be impossible to know their importance) and to detail the relations which we should have with them, considering them both in relation to commerce and with respect to the war of enslavement. In the second, of a confidential nature, he outlines the policy, which, in his opinion, should be adopted in order to obtain all the advantages which our position affords. In the third, number 16, he states the measures which should be adopted for the benefit of the national commerce in those countries. In the fourth, number 20, he transmits a copy of the treaty of peace, protection and commerce concluded with the Sultan of Sulu, and of the stipulations made for the determination of the duties which our vessels should pay in Sulu, and the Sulus in Manila and Zamboanga. In the fifth, number 21, he relates the motives which have led him to direct these matters as he has done, transmitting to her Majesty all the plans referring to it, through this Ministry only. In the sixth, number 22, he gives account of some of the advantages which have been derived from our expedition to Sulu, and amongst others, a treaty of peace concluded between the pueblo of Malusu and the Governor of Zamboanga. And finally, in the seventh, number 23, he sets forth the necessity of retaining at that station, the frigate-captain, Don José María Halcon, who performed the duty of commissioner for the negotiation of the treaty.

I have informed her Majesty, the Queen Regent, of the contents of all these communications, and in this knowledge she has seen fit to approve, in a general manner, all the measures adopted by the aforementioned predecessor of your Excellency, giving suitable orders, that the proper Ministry provide the special approval which some of them deserve, on account of their weight and importance, concerning which your Excellency will soon be informed, and deigning to command me to submit in a separate and particular communication the following advice on the special subject of the letters referred to above.

Her Majesty, feeling assured that conquests in themselves, and later their maintenance, absorb the profits which accrue from the countries already acquired, prefers to any conquest advantageous trade and commerce. Convinced, therefore, that the most profitable and lucrative policy is to conquer or secure such places as on account of their fortunate location may prove to be at the same time strong military and mercantile posts and so both promote and protect commerce, she cannot but approve the ideas your Excellency’s predecessor expresses in his communication numbered 14, and desires, that upon adopting the system in accordance with those ideas, you confine yourself solely, in all enterprises of conquest, to occupation of territory either abandoned or uninhabited, or to that which, notwithstanding its being settled, would cost little and would not give occasion for a costly war. In order to increase our commercial advantages in Sulu, and to raise up rivals to the Portuguese, it would be well to grant protection and reduction in duties to the Chinese junks[56] under the specific condition that they do not sail under the flag of any other nation (without mentioning the Portuguese by name in order not to occasion the resentment of this power) and to secure in Sulu for those who adopt the Spanish flag, a reduction of duties although not as much as that which should be granted to Spanish vessels. Thus it is the will of her Majesty that you be directed, commanding, with the same purpose in view, that your predecessor state to you explicitly, which are the measures that he would have adopted, had he been authorized to do so, in order to avoid the blow to our commerce threatened by the Portuguese, depriving us with the double expedition from Macao and Singapore to Sulu, of the advantage over all other nations which still remained to us in this traffic; and that your Excellency obstruct, by all the means in your power, the association of interests between the commercial houses of Manila with those of Macao and Singapore, if the same were intended to secure special privileges in the island of Sulu to the products of the Philippines to the injury of the national commerce.

With respect to the matter of the war against piracy, referred to also in letter number 14, her Majesty approves all the purposes expressed therein by the predecessor of your Excellency, and commands me to direct your Excellency that, without ever recurring to war or the interruption of traffic with Sulu as means of destroying or diminishing piracy and traffic in slaves, you exert yourself to suppress the same and remedy the evil which it inflicts on the Philippines, by the various means at hand, to-wit; 1st, through negotiations with the Sultan of Sulu; in which measures suitable for the accomplishment of the purpose may be concerted; 2d, securing the increase, by the Sultan, of import duties on slaves who are Spanish subjects, and the lowering of duties on slaves of other countries; 3d, requesting of him assistance in driving out the pirates from their haunts of Balangingi and other places; 4th, watching the rendezvous of these pirates in the Bisayas also, in order to destroy them. In this manner and with hard lessons, with the energetic and continuous warfare spoken of by the predecessor of your Excellency, the extermination of piracy will be accomplished without the evils which would follow upon an unwise and useless war against Sulu, and without the more serious result to which the same would expose us, and which her Majesty desires your Excellency to avoid at any cost, the result referred to being the removal of the Sultan to some other point, which removal England and Holland might turn to great advantage against our trade.

As to the measures proposed in letter number 16, for the benefit of the national commerce, her Majesty will determine which is fit, notifying your Excellency in due season. Meanwhile you should keep in mind, that as long as the Sulus man their ships with slaves, your Excellency should prohibit them from trading in Zamboanga and all other places within the dominions of her Majesty, whenever the ships which they use shall be manned in whole or in part with slaves who are subjects of Spain.

Concerning the treaty of peace, protection and commerce, a copy of which is inclosed in letter number 20, her Majesty has been pleased to resolve, after careful examination, that it be forwarded with favorable comment to the Ministry of State for the approval of the Cortes and the ratification of her Majesty, all of which will be communicated to your Excellency in due time, its policy being carried out and its intent carefully observed in the meanwhile, for the purpose of determining whether there is anything to amend or correct by means of further negotiation, which would be considered as an appendix to the treaty. In view of the explanations concerning the first article of the aforementioned treaty furnished by the commissioner of the negotiation, her Majesty commands me to repeat to your Excellency the necessity for carrying out the policy which is prescribed to your Excellency with regard to acquisition and conquest; in order to claim those lands referred to in the explanations, if perchance such claim should be advisable for the purpose of acquiring some point of military or mercantile value: or in order to set up the claim of the Kingdom of Spain to those countries, in order that by giving it up, we may secure other things which may be of real importance to us, such as reduction in duties, some exclusive privilege, or the possession of some isolated point of great importance.

The predecessor of your Excellency by addressing to this Ministry all communications bearing on this matter, has merited the approbation of her Majesty, because he has avoided many unnecessary steps and useless delay, and thus your Excellency will continue to do, in the manner herein indicated.

And finally, her Majesty having noted with satisfaction the favorable results produced already by the expedition to Sulu, and approving the idea of not using the fifteen hundred dollars sent by the Bishop of Nueva Segovia for the redemption of slaves, she commands me to direct your Excellency to cultivate the friendship of all the chiefs who, like the Orankaya of Malusu, abandon the pursuit of piracy, and that suitable orders be issued by the Division of the Marine of this Ministry, not only that the captain of frigate, Don José María Halcon, who has so well discharged the duty of negotiating the treaty, be assigned to that station, but that he also be duly rewarded for his services as such commissioner; her Majesty not failing to express the gratitude with which she declares her appreciation to the predecessor of your Excellency, the aforementioned Don Pedro Antonio Salazar. All of which is communicated to your Excellency, by Royal order, for your due information and guidance, instructing you with regard to the confidential letter, that you carry out the directions forwarded you separately under this date. God preserve your Excellency.
