An interesting memoir on the timber trees of Ceylon has been prepared by a native officer at Colombo, Adrian Mendis, of Morottu, carpeater-moodliar to the Royal Engineers, in which he has enumerated upwards of ninety species, which, in various parts of the island, are employed either as timber or cabinet woods.[1] Of these, the jak, the Kangtal of Bengal (_Artocarpus integrifolia_), is, next to the coco-nut and Palmyra, by far the most valuable to the Singhalese; its fruit, which sometimes attains the weight of 50 lbs., supplying food for their table, its leaves fodder for their cattle, and its trunk timber for every conceivable purpose both oeconomic and ornamental. The Jak tree, as well as the Del, or wild bread-fruit, is indigenous to the forests on the coast and in the central provinces; but, although the latter is found in the vicinity of the villages, it does not appear to be an object of special cultivation. The Jak, on the contrary, is planted near every house, and forms the shade of every garden. Its wood, at first yellow, approaches the colour of mahogany after a little exposure to the air, and resembles it at all times in its grain and marking. [Footnote 1: Mendis' List will be found appended to the _Ceylon Calendar_ for 1854.] The Del (_Artocarpus pubescens_) affords a valuable timber, not only for architectural purposes, but for ship-building. It and the Halmalille[1] resembling but larger than the linden tree of England, to which it is closely allied, are the favourite building woods of the natives, and the latter is used for carts, casks, and all household purposes, as well as for the hulls of their boats, from the belief that It resists the attack of the marine worms, and that some unctuous property in the wood preserves the iron work from rust.[2] [Footnote 1: Berry a ammonilla.] [Footnote 2: The Masula boats, which brave the formidable surf of Madrus are made of Halmalille, which is there called "Trincomalie wood" from the place of exportation.]
