To the Captain-General of the Philippine Islands.

Most illustrious Sir: In letters Nos. 322 and 325, your Excellency sets forth the ideas of the English settled in the island of Balambangan, who are displeased with the unhealthfulness of the country and petition that the Sultan of Sulu allow them to settle within his dominions.

With No. 325, the letter of the Sultan was received, and the King, thus informed of the attempts of the Englishmen, and also of the favorable inclination of the Sulu Sultan to establish with our nation friendship and alliance, commands me to direct you to listen to his proposals, to accede to them whenever they are reasonable, and to grant him aid and favor as far as possible, assuring him of Royal protection, and delivering to him the enclosed communication in answer to his own, in which his Catholic Majesty declares his entire satisfaction with his reasonable conduct and promises to reciprocate his friendship as you may understand through the copy of that letter which I enclose. God preserve your Excellency many years.

Madrid, December 5, 1774.

Dr. Julian de Biriaga.

[Copy of the communication referred to in the foregoing letter.]

Most illustrious and excellent prince Mohammed Israel, Sultan of Sulu. Most gratifying has been to me the announcement, which you conveyed to me in your letter of January 20th, of your happy accession to the sovereignty of Sulu, on account of which I offer you many congratulations, wishing you happiness in all things.

The disposition which inclines you to seek my friendship and assistance, as also the friendly relations which you maintain with my Governor of the Philippines, which you desire to establish and perpetuate by means of a mutual agreement, which may secure for the future firm peace and a perpetual alliance between your states and mine, increase my just gratification, especially as my Governor has informed me of the sublime natural gifts which are united in your person, with many and most expressive eulogies thereof.

In view of this, and of the constant fidelity which you promise in your letter, I command my good vassal, Don Simon de Anda y Salazar, to listen to your proposals, to accede to them whenever reasonable, and to grant you all the favor and assistance which the forces and facilities to be found there may allow assuring you of my Royal protection, which I extend to you from now on, confiding in your reciprocal friendship, and noble conduct, and desirous of opportunities of favoring you and of proving the interest which I feel in your good fortunes and the earnestness with which I pray God to preserve you many years.

Madrid, December 2, 1774.
