Note 3 — XXII

Balao oil.A resinous oil (balao or malapajo) is found in Samar and Albay, probably also in other provinces. It is obtained from a dipterocarpus (apiton), one of the loftiest trees of the forest, by cutting in the trunk a wide hole, half a foot deep, hollowed out into the form of a basin, and from time to time lighting a fire in it, so as to free the channels, through which it flows, of obstructions. The oil thus is collected daily and comes into commerce without any further preparation. Its chief application is in the preservation of iron in shipbuilding. Nails dipped in the oil of the balao, before being driven in, will, as I have been assured by credible individuals, defy the action of rust for ten years; but it is principally used as a varnish for ships, which are painted with it both within and without, and it also protects wood against termites and other insects. The balao is sold in Albay at four reals for the tinaja of ten gantas (the liter at eight pence). A cement formed by the mixture of burnt lime, gum elemi, and coconut oil, in such proportions as to form a thick paste before application, is used for the protection of the bottoms of ships; and the coating is said to last a year.3 Wax.Wax is bartered by the Cimarronese. The whole of Samar annually yields from two hundred to three hundred piculs, whose value ranges between twenty-five and fifty dollars per picul, while in Manila the price is generally five to ten dollars higher; but it fluctuates very much, as the same product is brought from many other localities and at very irregular intervals of time.
