[68] Crawfurd (_Dict. Indian Islands_) says that this is the eagle-wood of commerce. Its name in Malay and Javanese is _kalambak_ or _kalambah_, but it is also known in these languages by that of _gahru_, or _kayu-gahru_, gahru-wood, a corruption of the Sanscrit _Agharu_. This sweet-scented wood has been used immemorially as an incense throughout eastern countries, and was early introduced into Europe by the Portuguese. The perfumed wood is evidently the result of a disease in the tree, produced by the thickening of the sap into a gum or resin. The tree is confused with the aloes, but properly speaking has no connection with that tree; and the word _agila_ has been wrongly translated into "eagle" [see above "_aguila_"]. The tree probably belongs to the order of _Leguminosae_. The best perfumed or diseased wood is found in the mountainous country to the east of the Gulf of Siam, including Camboja and Cochinchina. Castenheda says that at Campar, on the eastern side of Sumatra, are "forests which yield aloes-wood, called in India Calambuco (kalambak). The trees which produce it are large, and when they are old they are cut down and the aloes-wood taken from them, which is the heart of the tree, and the outer part is agila. Both these woods are of great price, but especially the Calambuco, which is rubbed in the hands, yielding an agreeable fragrance; the agila does so when burned." See Crawfurd, _ut supra_, pp. 6, 7, and Yule's Cathay, ii, p. 472, note 1. [69] _Calambac_: the kalambac, or normal form of the wood called agila, is evidently meant here; see preceding note. [70] See _Vol_. IV, pp. 99, 100. All the old books of voyages of eastern countries contain much on the buying and selling prices of various commodities. See especially the notable Hakluyt Society publications.
