The rangas or rungi, commonly supposed to be the manchineel of the West Indies, but perhaps only from the noxious quality of its juices, is the Arbor vernicis of Rumphius, and particularly described in the Batavian Transactions Volume 5 under the name of Manga deleteria sylvestris, fructu parvo cordiformi. In a list of plants in the same volume, by F. Norona, it is termed Anacardium encardium. The wood has some resemblance to mahogany, is worked up into articles of furniture, and resists the destructive ravages of the white ant, but its hardness and acrid sap, which blisters the hands of those employed about it, are objections to its general use. I am not aware of the natives procuring a varnish from this tree.
Of the various sorts of tree producing dammar, some are said to be valuable as timber, particularly the species called dammar laut, not mentioned by Rumphius, which is employed at Pulo Pinang for frame timbers of ships, beams, and knees.
Kamuning (camunium, R. chalcas paniculata, Lour.) is a light-coloured wood, close, and finely grained, takes an exquisite polish, and is used for the sheaths of krises. There is also a red-grained sort, in less estimation. The appearance of the tree is very beautiful, resembling in its leaves the larger myrtle, with a white flower.
The langsani likewise is a wood handsomely veined, and is employed for cabinet and carved work.
Beside these the kinds of wood most in use are the madang, ballam, maranti, laban, and marakuli. The variety is much greater, but many, from their porous nature and proneness to decay, are of very little value, and scarcely admit of seasoning before they become rotten.
I cannot quit the vegetable kingdom without noticing a tree which, although of no use in manufacture or commerce, not peculiar to the island, and has been often described, merits yet, for its extreme singularity, that it should not be passed over in silence. This is the jawi-jawi and ulang-ulang of the Malays, the banyan tree of the continent, the Grossularia domestica of Rumphius, and the Ficus indica or Ficus racemosa of Linnaeus. It possesses the uncommon property of dropping roots or fibres from certain parts of its boughs, which, when they touch the earth, become new stems, and go on increasing to such an extent that some have measured, in circumference of the branches, upwards of a thousand feet, and have been said to afford shelter to a troop of horse.* These fibres, that look like ropes attached to the branches, when they meet with any obstruction in their descent conform themselves to the shape of the resisting body, and thus occasion many curious metamorphoses. I recollect seeing them stand in the perfect shape of a gate long after the original posts and cross piece had decayed and disappeared; and I have been told of their lining the internal circumference of a large bricked well, like the worm in a distiller's tub; there exhibiting the view of a tree turned inside out, the branches pointing to the centre, instead of growing from it. It is not more extraordinary in its manner of growth than whimsical and fantastic in its choice of situations. From the side of a wall or the top of a house it seems to spring spontaneously. Even from the smooth surface of a wooden pillar, turned and painted, I have seen it shoot forth, as if the vegetative juices of the seasoned timber had renewed their circulation and begun to produce leaves afresh. I have seen it flourish in the centre of a hollow tree of a very different species, which however still retained its verdure, its branches encompassing those of the adventitious plant whilst its decayed trunk enclosed the stem, which was visible, at interstices, from nearly the level of the plain on which they grew. This in truth appeared so striking a curiosity that I have often repaired to the spot to contemplate the singularity of it. How the seed from which it is produced happens to occupy stations seemingly so unnatural is not easily determined. Some have imagined the berries carried thither by the wind, and others, with more appearance of truth, by the birds; which, cleansing their bills where they light, or attempt to light, leave, in those places, the seeds adhering by the viscous matter which surrounds them. However this be, the jawi-jawi, growing on buildings without earth or water, and deriving from the genial atmosphere its principle of nourishment, proves in its increasing growth highly destructive to the fabric where it is harboured; for the fibrous roots, which are at first extremely fine, penetrate common cements, and, overcoming as their size enlarges the most powerful resistance, split, with the force of the mechanic wedge, the most substantial brickwork. When the consistence is such as not to admit the insinuation of the fibres the root extends itself along the outside, and to an extraordinary length, bearing not unfrequently to the stem the proportion of eight to one when young. I have measured the former sixty inches, when the latter, to the extremity of the leaf, which took up a third part, was no more than eight inches. I have also seen it wave its boughs at the apparent height of two hundred feet, of which the roots, if we may term them such, occupied at least one hundred; forming by their close combination the appearance of a venerable gothic pillar. It stood near the plains of Krakap, but, like other monuments of antiquity, it had its period of existence, and is now no more.
(*Footnote. The following is an account of the dimensions of a remarkable banyan or burr tree, near Manjee, twenty miles west of Patna in Bengal. Diameter 363 to 375 feet. Circumference of shadow at noon 1116 feet. Circumference of the several stems, in number fifty or sixty, 921 feet. Under this tree sat a naked Fakir, who had occupied that situation for twenty-five years; but he did not continue there the whole year through, for his vow obliged him to lie, during the four cold months, up to his neck in the waters of the river Ganges.)
