Governor Don Diego de Salcedo, considering the many oppressions that were experienced by the provinces near Manila from the continual cutting of timber and building of galleons--a necessary evil, and one in which the wrongs that are committed in it can be obviated only with great difficulty--very prudently determined to build the galleon "Nuestra Señora del Buen Socorro" in the province of Albay. He entrusted its execution to the commander Diego de Arévalo who was most experienced in maritime matters. He appointed him alcalde-mayor of the adjoining province of Camarines, for the better expedition of the timber-cutting, putting him under greater obligations [to do well] by the future reward of commander of the galleon which he was about to build. In order that that galleon might be built more quickly and finished sooner, he sent as chief overseer his lieutenant master-of-camp, Don Agustín de Cepada Carnacedo, who was then master-of-camp of the army of these islands for his Majesty, in order that he might live in the port of Albay. He did that with so great care that in little more than one year the largest and best galleon that had yet been seen in the islands was built--and very few so large have been seen in European seas, and extremely few that are larger. For that purpose the woods of Filipinas are the best that can be found in all the universe; because for the inside work, the ribs and knees, the keel and rudder molave is used--which is the hardest wood known; and at its disintegration it is converted into stone by being kept in the water. Lavang [141] is used for the sheathing outside the ribs; it is so strong and of such a nature that no artillery ball will pass through it; and the greatest harm that the ball can do is to stick in the wood without entering inside the ship. On account of that advantage the galleons of these islands are so formidable to the Dutch; for each one is a strong castle in the sea. When the galleon "Nuestra Señora del Buen Socorro" was finished, it sailed from Albay, August 28, 1667, under command of Diego de Arévalo, with Juan Rodriguez, a Portuguese, as its chief pilot. The patache "San Diego" left Cavite to accompany it, under charge of Admiral Bartolomé Muñoz. They had a fortunate voyage, and arrived in due time at the port of Acapulco.
