The History of Sumatra Part 15

CULTURE LEFT TO INDIVIDUALS.

It is understood that the Company has declined the monopoly of the trade and left the cultivation to individual exertion; directing however that its own immediate plantations be kept up by the labour of convicts from Bengal, and reserving to itself an export duty of ten per cent on the value of the spices.

CAMPHOR.

Among the valuable productions of the island as articles of commerce a conspicuous place belongs to the camphor.

This peculiar substance, called by the natives kapur-barus,* and distinguished by the epithet of native camphor from another sort which shall be mentioned hereafter, is a drug for which Sumatra and Borneo have been celebrated from the earliest times, and with the virtues of which the Arabian physicians appear to have been acquainted. Chemists formerly entertained opinions extremely discordant in regard to the nature and the properties of camphor; and even at this day they seem to be but imperfectly known. It is considered however as a sedative and powerful diaph.o.r.etic: but my province is to mention such particulars of its history as have come within my knowledge, leaving to others to investigate its most beneficial uses.

(*Footnote. The word kapur appears to be derived from the Sanskrit karpura, and the Arabic and Persian kafur (from whence our camphor) to have been adopted from the language of the country where the article is produced. Barus is the name of a place in Sumatra.)

PLACE OF GROWTH.

The tree is a native of the northern parts of the island only, not being found to the southward of the line, nor yet beyond the third degree of north lat.i.tude. It grows without cultivation in the woods lying near to the sea-coast, and is equal in height and bulk to the largest timber trees, being frequently found upwards of fifteen feet in circ.u.mference.

WOOD.

For carpenters' purposes the wood is in much esteem, being easy to work, light, durable, and not liable to be injured by insects, particularly by the k.u.mbang, a species of the bee, whose destructive perforations have been already mentioned; but is also said to be more affected than most others by the changes of the atmosphere. The leaf is small, of a roundish oval, the fibres running straight and parallel to each other, and terminates in a remarkably long and slender point. The flower has not yet been brought to England. The fruit is described by C.F. Gaertner (De Seminibus Volume 3 page 49 tab. 186) by the name of Dryobalanops aromatica, from specimens in the collection of Sir Joseph Banks; but he has unaccountably mistaken it for the cinnamon tree, and spoken of it as a native of Ceylon. It is also described, from the same specimens, by M.

Correa de Serra (Annales du Museum d'Histoire Naturelle Tome 10 page 159 plate 8) by the name of Pterigium teres; without any reference whatever to the nature of the tree as yielding this valuable drug. A beautiful engraving of its very peculiar foliage has been made under the direction of Mr. A.B. Lambert.

CAMPHOR FOUND IN THE FISSURES.

The camphor is found in the concrete state in which we see it, in natural fissures or crevices of the wood, but does not exhibit any exterior appearance by which its existence can be previously ascertained, and the persons whose employment it is to collect it usually cut down a number of trees, almost at random, before they find one that contains a sufficient quant.i.ty to repay their labour, although always a.s.sisted in their research by a professional conjurer, whose skill must be chiefly employed in concealing or accounting for his own mistakes. It is said that not a tenth part of the number felled is productive either of camphor or of camphor-oil (meniak kapur), although the latter is less rare; and that parties of men are sometimes engaged for two or three months together in the forests, with very precarious success. This scarcity tends to enhance the price. The tree when cut down is divided transversely into several blocks, and these again are split with wedges into small pieces, from the interstices of which the camphor, if any there be, is extracted. That which comes away readily in large flakes, almost transparent, is esteemed the prime sort or head; the smaller, clean pieces are considered as belly, and the minute particles, chiefly sc.r.a.ped from the wood, and often mixed with it, are called foot; according to the customary terms adopted in the a.s.sortment of drugs. The mode of separating it from these and other impurities is by steeping and washing it in water, and sometimes with the aid of soap. It is then pa.s.sed through sieves or screens of different apertures in order to make the a.s.sortment, so far as that depends upon the size of the grains; but much of the selection is also made by hand, and particular care is taken to distinguish from the more genuine kinds that which is produced by an artificial concretion of the essential oil.

CAMPHOR OIL.

The inquiries I formerly made on the subject (not having been myself in the district where the tree grows) led me to believe with confidence that the oil and the dry crystallized resin were not procured from the same individual tree; but in this I was first undeceived by Mr. R. Maidman, who in June 1788 wrote to me from Tappanuli, where he was resident, to the following effect:

I beg your acceptance of a piece of camphor-wood, the genuine quality of which I can answer for, being cut by one of my own people, who was employed in making charcoal, of which the best for smiths' work is made from this wood. On cutting deep into a pretty large tree the fine oil suddenly gushed out and was lost for want of a receiver. He felled the tree, and, having split it, brought me three or four catties (four or five pounds) of the finest camphor I ever saw, and also this log, which is very rich. My reason for being thus particular is that the country people have a method of pouring oil of inferior camphor-trees into a log of wood that has natural cracks, and, by exposing this to the sun every day for a week, it appears like genuine camphor; but is the worst sort.

This coexistence of the two products has been since confirmed to me by others, and is particularly stated by Mr. Macdonald in his ingenious paper on certain Natural Productions of Sumatra, published in the Asiatic Researches Volume 4 Calcutta 1795. It seems probable on the whole that, as the tree advances in age, a greater proportion of this essential oil takes a concrete form, and it has been observed to me that, when the fresh oil has been allowed to stand and settle, a sediment of camphor is procured; but the subject requires further examination by well-informed persons on the spot.

PRICE.

Head camphor is usually purchased from those who procure it at the rate of six Spanish dollars the pound, or eight dollars the catty, and sells in the China market at Canton for nine to twelve dollars the pound, or twelve to fifteen hundred dollars the pekul of a hundred catties or one hundred thirty-three pounds and a third, avoirdupois. When of superior quality it sells for two thousand dollars, and I have been a.s.sured that some small choice samples have produced upwards of thirty dollars per catty.* It is estimated that the whole quant.i.ty annually brought down for sale on the western side of the island does not exceed fifty pekul. The trade is chiefly in the hands of the Achinese settled at Sinkell, who buy the article from the Batta people and dispose of it to the Europeans and Chinese settlers.

(*Footnote. See Price Currents of the China trade. Camphor was purchased in Sumatra by Commodore Beaulieu in 1622 at the rate of fifteen Spanish dollars for twenty-eight ounces, which differs but little from the modern price. In the Transactions of the Society at Batavia it appears that the camphor of Borneo sells in their market for 3200 rix dollars, and that of j.a.pan for 50 rix dollars the pekul.)

j.a.pAN CAMPHOR.

It has been commonly supposed that the people of China or j.a.pan prepare a fact.i.tious substance resembling native camphor, and impregnated with its virtues by the admixture of a small quant.i.ty of the genuine, which is sold to the Dutch factory for thirty or forty dollars the pekul, sent to Holland, and afterwards refined to the state in which we see it in our shops, where it is sold at eight to twelve shillings the pound. It appears however an extraordinary circ.u.mstance that any article could possibly be so adulterated, bearing at the same time the likeness and retaining the sensible qualities of its original, as that the dealers should be enabled, with profit to themselves to resell it for the fiftieth part of the price they gave. But, upon inquiry of an ingenious person long resident in China, I learned that the j.a.pan camphor is by no means a fact.i.tious substance, but the genuine produce of a tree growing in abundance in the latter country, different in every character from that of Sumatra or Borneo, and well known to our botanists by the name of Laurus camphora, L. He further informed me that the Chinese never mix the Sumatran camphor with that from j.a.pan, but purchase the former for their own use, at the before-mentioned extravagant price, from an idea of its efficacy, probably superst.i.tious, and export the latter as a drug not held in any particular estimation. Thus we buy the leaves of their tea-plant at a high rate and neglect herbs, the natives of our own soil, possessing perhaps equal virtues. It is known also that the j.a.pan camphor, termed fact.i.tious, will evaporate till it wholly disappears, and at all stages of its diminution retain its full proportion of strength; which does not seem the property of an adulterated or compounded body.

Kaempfer informs us that it is prepared from a decoction of the wood and roots of the tree cut into small pieces; and the form of the lumps in which it is brought to us shows that it has undergone a process. The Sumatran sort, though doubtless from its extreme volatility it must be subject to decrease, does not lose any very sensible quant.i.ty from being kept, as I find from the experience of many years that it has been in my possession. It probably may not be very easy to ascertain its superiority over the other in the materia medica, not being brought for sale to this country, nor generally administered; but from a medical person who practised at Bencoolen I learned that the usual dose he gave was from half a grain to one or two grains at the most. The oil, although hitherto of little importance as an article of commerce, is a valuable domestic medicine, and much used by the natives as well as Europeans in cases of strains, swellings, and rheumatic pains; its particles, from their extreme subtlety, readily entering the pores. It undergoes no preparation, and is used in the state in which, upon incision, it has distilled from the tree. The kayu putih (Melaleuca leucadendron) oil, which is somewhat better known in England, is obtained in the same manner; but to procure the meniak kayu or common wood-oil, used for preserving timber or boards exposed to the weather, from decay, and for boiling with dammar to pay the bottoms of ships and boats, the following method is practised. They make a transverse incision into the tree to the depth of some inches, and then cut sloping down from the notch, till they leave a flat superficies. This they hollow out to a capacity to receive about a quart. They then put into the hollow a bit of lighted reed, and let it remain for about ten minutes, which, acting as a stimulus, draws the fluid to that part. In the s.p.a.ce of a night the liquor fills the receptacle prepared for it, and the tree continues to yield a lesser quant.i.ty for three successive nights, when the fire must be again applied: but on a few repet.i.tions it is exhausted.

BENZOIN.

Benzoin or Benjamin (Styrax benzoin*) called by the Malays kaminian, is, like the camphor, found almost exclusively in the Batta country, to the northward of the equator, but not in the Achinese dominions immediately beyond that district. It is also met with, though rarely, south of the line, but there, either from natural inferiority or want of skill in collecting it, the small quant.i.ty produced is black and of little value.

The tree does not grow to any considerable size, and is of no value as timber. The seeds or nuts, which are round, of a brown colour, and about the size of a moderate bolus, are sown in the padi-fields and afterwards require no other cultivation than to clear away the shrubs from about the young plants. In some places, especially near the sea-coast, large plantations of it are formed, and it is said that the natives, sensible of the great advantage accruing to them from the trade, in a national point of view, oblige the proprietors, by legal regulation, to keep up the succession.

(*Footnote. See a Botanical Description of this tree by my friend Mr.

Jonas Dryander, with a plate, in Volume 77 page 307 of the Philosophical Transactions for the year 1787.)

MODE OF PROCURING IT.

When the trees have attained the age of about seven years, and are six or eight inches in diameter, incisions are made in the bark, from whence the balsam or gum (as it is commonly termed, although being soluble in spirits and not in water, it is rather a resin) exudes, which is carefully pared off. The purest of the gum, or Head benzoin, is that which comes from these incisions during the first three years, and is white, inclining to yellow, soft, and fragrant; after which it gradually changes to the second sort, which is of a reddish yellow, degenerating to brown; and at length when the tree, which will not bear a repet.i.tion of the process for more than ten or twelve years, is supposed to be worn out, they cut it down, and when split in pieces procure, by sc.r.a.ping, the worst sort, or Foot benzoin, which is dark coloured, hard, and mixed more or less with parings of the wood and other impurities. The Head is further distinguished into Europe and India-head, of which the first is superior, and is the only sort adapted to the home market: the latter, with most of the inferior sorts, is exported to Arabia,* Persia, and some parts of India, where it is burned to perfume with its smoke their temples and private houses, expel troublesome insects, and obviate the pernicious effects of unwholesome air or noxious exhalations; in addition to which uses, in the Malayan countries, it is always considered as a necessary part of the apparatus in administering an oath. It is brought down from the country for sale in large cakes, called tampang, covered with mats; and these, as a staple commodity, are employed in their dealings for a standard of value, to which the price of other things have reference, as in most parts of the world to certain metals. In order to pack it in chests it is necessary to soften the coa.r.s.er sorts with boiling water; for the finer it is sufficient to break the lumps and to expose it to the heat of the sun. The greater part of the quant.i.ty brought to England is re-exported from thence to countries where the Roman Catholic and Mahometan religions prevail, to be there burnt as incense in the churches and temples.** The remainder is chiefly employed in medicine, being much esteemed as an expectorant and styptic, and const.i.tutes the basis of that valuable balsam distinguished by the name of Turlington, whose very salutary effects, particularly in healing green and other wounds, is well known to persons abroad who cannot always obtain surgical a.s.sistance. It is also employed, if I am not misinformed, in the preparation of court sticking-plaster. The gum or resin called dulang is named by us scented benzoin from its peculiar fragrance. The rasamala (Lignum papuanum of Rumphius, and Altingia excelsa of the Batavian Transactions) is a sort of wild benzoin, of little value, and not, in Sumatra, considered as an object of commerce.

(*Footnote. Les Arabes tirent beaucoup d'autres sortes d'encens de l'Habbesch, de Sumatra, Siam, Java, etc. et parmi celles-la une qu'ils appellent Bachor (bakhor) Java, et que les Anglois nomment Benzoin, est tres semblable a l'Oliban. On en exporte en grande quant.i.te en Turquie parles golfes d'Arabie et de Perse, et la moindre des trois especes de Benzoin, que les marchands vendent, est estimee meilleure que l'Oliban d'Arabie. Niebuhr, Description de l'Arabie page 126.)

(**Footnote. According to Mr. Jackson the annual importation of Benzoin at MoG.o.dor from London is about 13,000 pounds annually.)

Ca.s.sIA.

Ca.s.sia or kulit manis (Laurus ca.s.sia) is a coa.r.s.e species of cinnamon which flourishes chiefly, as well as the two foregoing articles, in the northern part of the island; but with this difference, that the camphor and benzoin grow only near the coast, whereas the ca.s.sia is a native of the central parts of the country. It is mostly procured in those districts which lie inland of Tapanuli, but it is also found in Musi, where Palembang River takes its rise. The leaves are about four inches long, narrower than the bay (to which tribe it belongs) and more pointed; deep green; smooth surface, and plain edge. The princ.i.p.al fibres take their rise from the peduncle. The young leaves are mostly of reddish hue.

The blossoms grow six in number upon slender footstalks, close to the bottom of the leaf. They are monopetalous, small, white, stellated in six points. The stamina are six, with one stile, growing from the germen, which stands up in three brownish segments, resembling a cup. The trees grow from fifty to sixty feet high, with large, spreading, horizontal branches, almost as low as the earth. The root is said to contain much camphor that may be obtained by boiling or other processes unknown on Sumatra. No pains is bestowed on the cultivation of the ca.s.sia. The bark, which is the part in use, is commonly taken from such of the trees as are a foot or eighteen inches diameter, for when they are younger it is said to be so thin as to lose all its qualities very soon. The difference of soil and situation alters considerably the value of the bark. Those trees which grow in a high rocky soil have red shoots, and the bark is superior to that which is produced in a moist clay, where the shoots are green. I have been a.s.sured by a person of extensive knowledge that the ca.s.sia produced on Sumatra is from the same tree which yields the true cinnamon, and that the apparent difference arises from the less judicious manner of quilling it. Perhaps the younger and more tender branches should be preferred; perhaps the age of the tree or the season of the year ought to be more nicely attended to; and lastly I have known it to be suggested that the mucilaginous slime which adheres to the inside of the fresh peeled rind does, when not carefully wiped off, injure the flavour of the ca.s.sia and render it inferior to that of the cinnamon. I am informed that it has been purchased by Dutch merchants at our India sales, where it sometimes sold to much loss, and afterwards by them shipped for Spain as cinnamon, being packed in boxes which had come from Ceylon with that article. The price it bears in the island is about ten or twelve dollars the pecul.

RATTANS.

Rattans or rotan (Calamus rotang) furnish annually many large cargoes, chiefly from the eastern side of the island, where the Dutch buy them to send to Europe; and the country traders for the western parts of India.

Walking-canes, or tongkat, of various kinds, are also produced near the rivers which open to the straits of Malacca.

COTTON.

In almost every part of the country two species of cotton are cultivated, namely, the annual sort named kapas (Gossypium herbaceum), and the shrub cotton named kapas besar (Gossypium herboreum). The cotton produced from both appears to be of very good quality, and might, with encouragement, be procured in any quant.i.ties; but the natives raise no more than is necessary for their own domestic manufactures. The silk cotton or kapok (bombax) is also to be met with in every village. This is, to appearance, one of the most beautiful raw materials the hand of nature has presented.

Its fineness, gloss, and delicate softness render it, to the sight and touch, much superior to the labour of the silkworm; but owing to the shortness and brittleness of the staple it is esteemed unfit for the reel and loom, and is only applied to the unworthy purpose of stuffing pillows and mattresses. Possibly it has not undergone a fair trial in the hands of our ingenious artists, and we may yet see it converted into a valuable manufacture. It grows in pods, from four to six inches long, which burst open when ripe. The seeds entirely resemble the black pepper, but are without taste. The tree is remarkable from the branches growing out perfectly straight and horizontal, and being always three, forming equal angles, at the same height: the diminutive shoots likewise grow flat; and the several gradations of branches observe the same regularity to the top. Some travellers have called it the umbrella tree, but the piece of furniture called a dumb-waiter exhibits a more striking picture of it.

BETEL-NUT.

The betel-nut or pinang (Areca catechu) before mentioned is a considerable article of traffic to the coast of Coromandel or Telinga, particularly from Achin.

COFFEE.

The coffee-trees are universally planted, but the fruit produced here is not excellent in quality, which is probably owing entirely to the want of skill in the management of them. The plants are disposed too close to each other, and are so much overshaded by other trees that the sun cannot penetrate to the fruit; owing to which the juices are not well ripened, and the berries, which become large, do not acquire a proper flavour. Add to this that the berries are gathered whilst red, which is before they have arrived at a due degree of maturity, and which the Arabs always permit them to attain to, esteeming it essential to the goodness of the coffee. As the tree is of the same species with that cultivated in Arabia there is little doubt but with proper care this article might be produced of a quality equal, perhaps superior, to that imported from the West Indies; though probably the heavy rains on Sumatra may prevent its attaining to the perfection of the coffee of Mocha.*

(*Footnote. For these observations on the growth of the coffee, as well as many others on the vegetable productions of the island, I am indebted to the letters of Mr. Charles Miller, entered on the Company's records at Bencoolen, and have to return him my thanks for many communications since his return to England. On the subject of this article of produce I have since received the following interesting information from the late Mr.

Charles Campbell in a letter dated November 1803. "The coffee you recollect on this coast I found so degenerated from want of culture and care as not to be worth the rearing. But this objection has been removed, for more than three years ago I procured twenty-five plants from Mocha; they produced fruit in about twenty months, are now in their second crop, and loaded beyond any fruit-trees I ever saw. The average produce is about eight pounds a tree; but so much cannot be expected in extensive plantations, nor in every soil. The berries are in no respect inferior in flavour to those of the parent country." This cultivation, I am happy to hear, has since been carried to a great extent.)

(PLATE 2. THE DAMMAR, A SPECIES OF PINUS.

DAMMAR.

The dammar is a kind of turpentine or resin from a species of pine, and used for the same purposes to which that and pitch are applied. It is exported in large quant.i.ties to Bengal and elsewhere. It exudes, or flows rather, spontaneously from the tree in such plenty that there is no need of making incisions to procure it. The natives gather it in lumps from the ground where it has fallen, or collect it from the sh.o.r.es of bays and rivers whither it has floated. It hangs from the bough of the tree which produces it in large pieces, and hardening in the air it becomes brittle and is blown off by the first high wind. When a quant.i.ty of it has fallen in the same place it appears like a rock, and thence, they say, or more probably from its hardness, it is called dammar batu; by which name it is distinguished from the dammar kruyen. This is another species of turpentine, yielded by a tree growing in Lampong, called kruyen, the wood of which is white and porous. It differs from the common sort, or dammar batu, in being soft and whitish, having the consistence and somewhat the appearance of putty. It is in much estimation for paying the bottoms of vessels, for which use, to give it firmness and duration, it ought to be mixed with some of the hard kind, of which it corrects the brittleness. The natives, in common, do not boil it, but rub or smear it on with their hands; a practice which is probably derived from indolence, unless, as I have been informed, that boiling it, without oil, renders it hard. To procure it, an incision is made in the tree.
