Note 3 — Philippine Ships and Shipbuilding

Perhaps the guijo (also spelt guiso or guisoc; Dipterocarpus guiso—Bl.), a wood of red color, which is strong, durable, tough, and elastic; it produces logs 75 feet long by 24 inches square, and is now used in Hongkong for wharf-decks and flooring, but in Manila for carriage shafts (U.S. Gazetteer of Philippine Islands). Blanco says that this tree is much esteemed for carriage-wheels, and is also used for topmasts and keels. The Indians call it guiso, but the Spaniards have corruptly called it guijo. It is common in Mindoro.
