[156] For identifications of these various woods, see VOLS. XII, p. 245 (molave), and XVIII, pp. 169-173. Tangili is the Tagálog name for various trees of the genera Dipterocarpus and Shorea, (of the same natural order). "Teak" is a corruption of the Malabar name for the tree known to botanists as Tectona grandis. According to Official Handbook (p. 356), it "exists in Mindanao, and said to exist in Negros." Blanco gives (Flora, p. 93), the following interesting account of its habitat: "The only teak tree of which I have first-hand knowledge is the one which exists in the village of Tanay, in Laguna de Bahi [i.e., Bay]. Formerly there were two, and they were planted by a Franciscan priest; it is not known whence the seed came. The Tanay people call it ticla.... It is common in some provinces of Visayas, in Negros Island, Zambales, Mindanao, and Butuan, as has recently been ascertained. The tree whose flowers I have seen is in Tanay, and has waited twenty-three years to bloom." [157] See VOL. XVIII, p. 177. The term is applied (Official Handbook, p. 332) to the sheaths, or fibers surrounding the leaf-stems, of a species of palm, Caryota urens. [158] Representación al Rey ... dirigida al mas seguro aumento del real erario (Madrid?, 1732), by Miguel de Zavala y Auñon. It is of interest to note that Viana must have been related to Zavala, since his name, in full, was Francisco Leandro de Viana Zavala Vehena Saenz de Villaverde; he was afterward made Conde de Tepa and Marqués de Prado Alegre. [159] Cacao is found throughout the archipelago; large quantities of cacao of excellent quality are produced in southern Mindanao and the district of Davao. The native product commands a better price than that imported from Singapore. Coffee is found throughout the islands; the best quality is grown in Batangas. (Official Handbook, p. 303.) Montero y Vidal says (Archipiélago Filipino, p. 61) that the islands produce cacao equal in quality to that of Caracas, and coffee that is superior in some respects to that of Mocha. See Jagor's account of cacao in the Philippines, its history, culture, and preparation, in his Reisen, pp. 76-81. [160] Marginal note by Viana.--"At this very time, men are obtaining in this bay many of the said shells, and some pearls of good luster." [161] Marginal note by Viana.--"The mulberry trees yield wonderfully in these islands, and, by making suitable plantations of them, and bringing silkworms from China, [the production of] this valuable article of commerce can be promoted." [162] Narra is the native name of the valuable timber trees in the genus Pterocarpus, especially P. indicas; it is sometimes called "the mahogany of the Philippines." The species alluded to by Viana is probably P. Blancoi, called apálit by the Pampangos; "the decoction of the wood is nephritic" (Official Handbook).
