If antiquity holds up to us some models, in different arts and sciences, which have been found inimitable, the moderns, on the other hand, have carried their inventions and improvements, in a variety of instances, to an extent and a degree of perfection of which the former could entertain no ideas. Among those discoveries in which we have stepped so far beyond our masters there is none more striking, or more eminently useful, than the means which the ingenuity of some, and the experience of others, have taught mankind, of determining with certainty and precision the relative situation of the various countries of the earth. What was formerly the subject of mere conjecture, or at best of vague and arbitrary computation, is now the clear result of settled rule, founded upon principles demonstratively just. It only remains for the liberality of princes and states, and the persevering industry of navigators and travellers, to effect the application of these means to their proper end, by continuing to ascertain the unknown and uncertain positions of all the parts of the world, which the barriers of nature will allow the skill and industry of man to approach.

SITUATION OF THE ISLAND.

Sumatra, the subject of the present work, is an extensive island in the East Indies, the most western of those which may be termed the Malayan Archipelago, and constituting its boundary on that side.

LATITUDE.

The equator divides it obliquely, its general direction being north-west and south-east, into almost equal parts; the one extremity lying in five degrees thirty-three minutes north, and the other in five degrees fifty-six minutes south latitude. In respect to relative position its northern point stretches into the Bay of Bengal; its south-west coast is exposed to the great Indian Ocean; towards the south it is separated by the Straits of Sunda from the island of Java; on the east by the commencement of the Eastern and China Seas from Borneo and other islands; and on the north-east by the Straits of Malacca from the peninsula of Malayo, to which, according to a tradition noticed by the Portuguese historians, it is supposed to have been anciently united.

LONGITUDE.

The only point of the island whose longitude has been settled by actual observation is Fort Marlborough, near Bencoolen, the principal English settlement, standing in three degrees forty-six minutes of south latitude. From eclipses of Jupiter's satellites observed in June 1769, preparatory to an observation of the transit of the planet Venus over the sun's disc, Mr. Robert Nairne calculated its longitude to be 101 degrees 42 minutes 45 seconds; which was afterwards corrected by the Astronomer Royal to 102 degrees east of Greenwich. The situation of Achin Head is pretty accurately fixed by computation at 95 degrees 34 minutes; and longitudes of places in the Straits of Sunda are well ascertained by the short runs from Batavia, which city has the advantage of an observatory.

MAP.

By the general use of chronometers in latter times the means have been afforded of determining the positions of many prominent points both on the eastern and western coasts, by which the map of the island has been considerably improved: but particular surveys, such as those of the bays and islets from Batang-kapas to Padang, made with great ability by Captain (now Lieutenant-Colonel) John Macdonald; of the coast from Priaman to the islands off Achin by Captain George Robertson; and of Siak River by Mr. Francis Lynch, are much wanted; and the interior of the country is still very imperfectly known. From sketches of the routes of Mr. Charles Campbell and of Lieutenant Hastings Dare I have been enabled to delineate the principal features of the Sarampei, Sungei Tenang and Korinchi countries, inland of Ipu, Moco-moco, and Indrapura; and advantage has been taken of all other information that could be procured. For the general materials from which the map is constructed I am chiefly indebted to the kindness of my friend, the late Mr. Alexander Dalrymple, whose indefatigable labours during a long life have contributed more than those of any other person to the improvement of Indian Hydrography. It may be proper to observe that the map of Sumatra to be found in the fifth volume of Valentyn's great work is so extremely incorrect, even in regard to those parts immediately subject to the Dutch government, as to be quite useless.

UNKNOWN TO THE ANCIENTS. TAPROBANE.

Notwithstanding the obvious situation of this island in the direct track from the ports of India to the Spice Islands and to China, it seems to have been unknown to the Greek and Roman geographers, whose information or conjectures carried them no farther than Selan-dib or Ceylon, which has claims to be considered as their Taprobane; although during the middle ages that celebrated name was almost uniformly applied to Sumatra. The single circumstance indeed of the latter being intersected by the equator (as Taprobane was said to be) is sufficient to justify the doubts of those who were disinclined to apply it to the former; and whether in fact the obscure and contradictory descriptions given by Strabo, Pomponius Mela, Pliny, and Ptolemy, belonged to any actual place, however imperfectly known; or whether, observing that a number of rare and valuable commodities were brought from an island or islands in the supposed extremity of the East, they might have been led to give place in their charts to one of vast extent, which should stand as the representative of the whole, is a question not to be hastily decided.

OPHIR.

The idea of Sumatra being the country of Ophir, whither Solomon sent his fleets for cargoes of gold and ivory, rather than to the coast of Sofala, or other part of Africa, is too vague, and the subject wrapped in a veil of too remote antiquity, to allow of satisfactory discussion; and I shall only observe that no inference can be drawn from the name of Ophir found in maps as belonging to a mountain in this island and to another in the peninsula; these having been applied to them by European navigators, and the word being unknown to the natives.

Until the discovery of the passage to India by the Cape of Good Hope the identity of this island as described or alluded to by writers is often equivocal, or to be inferred only from corresponding circumstances.

ARABIAN TRAVELLERS.

The first of the two Arabian travellers of the ninth century, the account of whose voyages to India and China was translated by Renaudot from a manuscript written about the year 1173, speaks of a large island called Ramni, in the track between Sarandib and Sin (or China), that from the similarity of productions has been generally supposed to mean Sumatra; and this probability is strengthened by a circumstance I believe not hitherto noticed by commentators. It is said to divide the Sea of Herkend, or Indian Ocean, from the Sea of Shelahet) Salahet in Edrisi), and Salat being the Malayan term both for a strait in general, and for the well-known passage within the island of Singapura in particular, this may be fairly presumed to refer to the Straits of Malacca.

EDRISI.

Edrisi, improperly called the Nubian geographer, who dedicated his work to Roger, King of Sicily, in the middle of the twelfth century, describes the same island, in the first climate, by the name of Al-Rami; but the particulars so nearly correspond with those given by the Arabian traveller as to show that the one account was borrowed from the other. He very erroneously however makes the distance between Sarandib and that island to be no more than three days' sail instead of fifteen. The island of Soborma, which he places in the same climate, is evidently Borneo, and the two passages leading to it are the Straits of Malacca and of Sunda. What is mentioned of Sumandar, in the second climate, has no relation whatever to Sumatra, although from the name we are led to expect it.

MARCO POLO.

Marco Polo, the celebrated Venetian traveller of the thirteenth century, is the first European who speaks of this island, but under the appellation of Java minor, which he gave to it by a sort of analogy, having forgotten, or not having learned from the natives, its appropriate name. His relation, though for a long time undervalued, and by many considered as a romantic tale, and liable as it is to the charge of errors and omissions, with some improbabilities, possesses, notwithstanding, strong internal evidence of genuineness and good faith. Containing few dates, the exact period of his visit to Sumatra cannot be ascertained, but as he returned to Venice in 1295, and possibly five years might have elapsed in his subsequent tedious voyages and journeys by Ceylon, the Karnatick, Malabar, Guzerat, Persia, the shores of the Caspian and Euxine, to Genoa (in a prison at which place he is said to have dictated his narrative), we may venture to refer it to the year 1290.

Taking his departure, with a considerable equipment, from a southern port of China, which he (or his transcriber) named Zaitum, they proceeded to Ziamba (Tsiampa or Champa, adjoining to the southern part of Cochin-China) which he had previously visited in 1280, being then in the service of the emperor Kublai Khan. From thence, he says, to the island of Java major is a course of fifteen hundred miles, but it is evident that he speaks of it only from the information of others, and not as an eyewitness; nor is it probable that the expedition should have deviated so far from its proper route. He states truly that it is a mart for spices and much frequented by traders from the southern provinces of China. He then mentions in succession the small uninhabited islands of Sondur and Condur (perhaps Pulo Condore); the province of Boeach otherwise Lochac (apparently Camboja, near to which Condore is situated); the island of Petan (either Patani or Pahang in the peninsula) the passage to which, from Boeach, is across a gulf (that of Siam); and the kingdom called Malaiur in the Italian, and Maletur in the Latin version, which we can scarcely doubt to be the Malayan kingdom of Singa-Pura, at the extremity of the peninsula, or Malacca, then beginning to flourish. It is not however asserted that he touched at all these places, nor does he seem to speak from personal knowledge until his arrival at Java minor (as he calls it) or Sumatra. This island, lying in a south-eastern direction from Petan (if he does not rather mean from Malaiur, the place last mentioned) he expressly says he visited, and describes it as being in circumference two thousand miles (not very wide of the truth in a matter so vague), extending to the southward so far as to render the Polar Star invisible, and divided into eight kingdoms, two of which he did not see, and the six others he enumerates as follows: Ferlech, which I apprehend to be Parlak, at the eastern extremity of the northern coast, where they were likely to have first made the land. Here he says the people in general were idolaters; but the Saracen merchants who frequented the place had converted to the faith of Mahomet the inhabitants of the towns, whilst those of the mountains lived like beasts, and were in the practice of eating human flesh. Basma or Basman: this nearly approaches in sound to Pasaman on the western coast, but I should be more inclined to refer it to Pase (by the Portuguese written Pacem) on the northern. The manners of the people here, as in the other kingdoms, are represented as savage; and such they might well appear to one who had long resided in China. Wild elephants are mentioned, and the rhinoceros is well described. Samara: this I suppose to be Samar-langa, likewise on the northern coast, and noted for its bay. Here, he says, the expedition, consisting of two thousand persons, was constrained to remain five months, waiting the change of the monsoon; and, being apprehensive of injury from the barbarous natives, they secured themselves, by means of a deep ditch, on the land side, with its extremities embracing the port, and strengthened by bulwarks of timber. With provisions they were supplied in abundance, particularly the finest fish. There is no wheat, and the people live on rice. They are without vines, but extract an excellent liquor from trees of the palm kind by cutting off a branch and applying to it a vessel which is filled in the course of a day and night. A description is then given of the Indian or coconut. Dragoian, a name bearing some though not much resemblance to Indragiri on the eastern coast; but I doubt his having proceeded so far to the southward as that river. The customs of the natives are painted as still more atrocious in this district. When any of them are afflicted with disorders pronounced by their magicians to be incurable their relations cause them to be suffocated, and then dress and eat their flesh; justifying the practice by this argument, that if it were suffered to corrupt and breed worms, these must presently perish, and by their deaths subject the soul of the deceased to great torments. They also kill and devour such strangers caught amongst them as cannot pay a ransom. Lambri might be presumed a corruption of Jambi, but the circumstances related do not justify the analogy. It is said to produce camphor, which is not found to the southward of the equinoctial line; and also verzino, or red-wood (though I suspect benzuin to be the word intended), together with a plant which he names birci, supposed to be the bakam of the Arabs, or sappan wood of the eastern islands, the seeds of which he carried with him to Venice. In the mountainous parts were men with tails a palm long; also the rhinoceros, and other wild animals. Lastly, Fanfur or Fansur, which corresponds better to Campar than to the island of Panchur, which some have supposed it. Here the finest camphor was produced, equal in value to its weight in gold. The inhabitants live on rice and draw liquor from certain trees in the manner before described. There are likewise trees that yield a species of meal. They are of a large size, have a thin bark, under which is a hard wood about three inches in thickness, and within this the pith, from which, by means of steeping and straining it, the meal (or sago) is procured, of which he had often eaten with satisfaction. Each of these kingdoms is said to have had its peculiar language. Departing from Lambri, and steering northward from Java minor one hundred and fifty miles, they reached a small island named Necuram or Norcueran (probably Nancowry, one of the Nicobars), and afterwards an island named Angaman (Andaman), from whence, steering to the southward of west a thousand miles, they arrived at that of Zeilan or Seilam, one of the most considerable in the world. The editions consulted are chiefly the Italian of Ramusio, 1583, Latin of Muller, 1671, and French of Bergeron, 1735, varying much from each other in the orthography of proper names.

ODORICUS.

Odoricus, a friar, who commenced his travels in 1318 and died at Padua in 1331, had visited many parts of the East. From the southern part of the coast of Coromandel he proceeded by a navigation of twenty days to a country named Lamori (perhaps a corruption of the Arabian Al-rami), to the southward of which is another kingdom named Sumoltra, and not far from thence a large island named Java. His account, which was delivered orally to the person by whom it was written down, is extremely meagre and unsatisfactory.

MANDEVILLE.

Mandeville, who travelled in the fourteenth century, seems to have adopted the account of Odoricus when he says, "Beside the isle of Lemery is another that is clept Sumobor; and fast beside a great isle clept Java."

NICOLO DI CONTI.

Nicolo di Conti, of Venice, returned from his oriental travels in 1449 and communicated to the secretary of Pope Eugenius IV a much more consistent and satisfactory account of what he had seen than any of his predecessors. After giving a description of the cinnamon and other productions of Zeilam he says he sailed to a great island named Sumatra, called by the ancients Taprobana, where he was detained one year. His account of the pepper-plant, of the durian fruit, and of the extraordinary customs, now well ascertained, of the Batech or Batta people, prove him to have been an intelligent observer.

ITINERARIUM PORTUGALLENSIUM.

A small work entitled Itinerarium Portugallensium, printed at Milan in 1508, after speaking of the island of Sayla, says that to the eastward of this there is another called Samotra, which we name Taprobane, distant from the city of Calechut about three months' voyage. The information appears to have been obtained from an Indian of Cranganore, on the coast of Malabar, who visited Lisbon in 1501.

LUDOVICO BARTHEMA.

Ludovico Barthema (Vartoma) of Bologna, began his travels in 1503, and in 1505, after visiting Malacca, which he describes as being the resort of a greater quantity of shipping than any other port in the world, passed over to Pedir in Sumatra, which he concludes to be Taprobane. The productions of the island, he says, were chiefly exported to Catai or China. From Sumatra he proceeded to Banda and the Moluccas, from thence returned by Java and Malacca to the west of India, and arrived at Lisbon in 1508.

ODOARDUS BARBOSA.

Odoardus Barbosa, of Lisbon, who concluded the journal of his voyage in 1516, speaks with much precision of Sumatra. He enumerates many places, both upon the coast and inland, by the names they now bear, among which he considers Pedir as the principal, distinguishes between the Mahometan inhabitants of the coast and the Pagans of the inland country; and mentions the extensive trade carried on by the former with Cambaia in the west of India.

ANTONIO PIGAFETTA.

In the account given by Antonio Pigafetta, the companion of Ferdinand Magellan, of the famous circumnavigatory voyage performed by the Spaniards in the years 1519 to 1522, it is stated that, from their apprehension of falling in with Portuguese ships, they pursued their westerly route from the island of Timor, by the Laut Kidol, or southern ocean, leaving on their right hand the island of Zamatra (written in another part of the journal, Somatra) or Taprobana of the ancients. Mention is also made of a native of that island being on board, who served them usefully as an interpreter in many of the places they visited; and we are here furnished with the earliest specimen of the Malayan language.

PORTUGUESE EXPEDITIONS.

Previously however to this Spanish navigation of the Indian seas, by the way of South America, the expeditions of the Portuguese round the Cape of Good Hope had rendered the island well known, both in regard to its local circumstances and the manners of its inhabitants.

EMANUEL KING OF PORTUGAL.

In a letter from Emanuel King of Portugal to Pope Leo the Tenth, dated in 1513, he speaks of the discovery of Zamatra by his subjects; and the writings of Juan de Barros, Castaneda, Osorius, and Maffaeus, detail the operations of Diogo Lopez de Sequeira at Pedir and Pase in 1509, and those of the great Alfonso de Alboquerque at the same places, in 1511, immediately before his attack upon Malacca. Debarros also enumerates the names of twenty of the principal places of the island with considerable precision, and observes that the peninsula or chersonesus had the epithet of aurea given to it on account of the abundance of gold carried thither from Monancabo and Barros, countries in the island of C(cedilla)amatra.

Having thus noticed what has been written by persons who actually visited this part of India at an early period, or published from their oral communication by contemporaries, it will not be thought necessary to multiply authorities by quoting the works of subsequent commentators and geographers, who must have formed their judgments from the same original materials.

NAME OF SUMATRA.

With respect to the name of Sumatra, we perceive that it was unknown both to the Arabian travellers and to Marco Polo, who indeed was not likely to acquire it from the savage natives with whom he had intercourse. The appellation of Java minor which he gives to the island seems to have been quite arbitrary, and not grounded upon any authority, European or Oriental, unless we can suppose that he had determined it to be the I'azadith nesos of Ptolemy; but from the other parts of his relation it does not appear that he was acquainted with the work of that great geographer, nor could he have used it with any practical advantage. At all events it could not have led him to the distinction of a greater and a lesser Java; and we may rather conclude that, having visited (or heard of) the great island properly so called, and not being able to learn the real name of another, which from its situation and size might well be regarded as a sister island, he applied the same to both, with the relative epithets of major and minor. That Ptolemy's Jaba-dib or dio was intended, however vaguely, for the island of Java, cannot be doubted. It must have been known to the Arabian merchants, and he was indefatigable in his inquiries; but at the same time that they communicated the name they might be ill qualified to describe its geographical position.

In the rude narrative of Odoricus we perceive the first approach to the modern name in the word Sumoltra. Those who immediately followed him write it with a slight, and often inconsistent, variation in the orthography, Sumotra, Samotra, Zamatra, and Sumatra. But none of these travellers inform us from whom they learned it; whether from the natives or from persons who had been in the habits of frequenting it from the continent of India; which latter I think the more probable. Reland, an able oriental scholar, who directed his attention to the languages of the islands, says it obtains its appellation from a certain high land called Samadra, which he supposes to signify in the language of the country a large ant; but in fact there is not any spot so named; and although there is some resemblance between semut, the word for an ant, and the name in question, the etymology is quite fanciful. Others have imagined that they find an easy derivation in the word samatra, to be met with in some Spanish or Portuguese dictionaries, as signifying a sudden storm of wind and rain, and from whence our seamen may have borrowed the expression; but it is evident that the order of derivation is here reversed, and that the phrase is taken from the name of the land in the neighbourhood of which such squalls prevail. In a Persian work of the year 1611 the name of Shamatrah occurs as one of those places where the Portuguese had established themselves; and in some very modern Malayan correspondence I find the word Samantara employed (along with another more usual, which will be hereafter mentioned) to designate this island.

PROBABLY DERIVED FROM THE SANSKRIT.

These, it is true, are not entirely free from the suspicion of having found their way to the Persians and Malays through the medium of European intercourse; but to a person who is conversant with the languages of the continent of India it must be obvious that the name, however written, bears a strong resemblance to words in the Sanskrit language: nor should this appear extraordinary when we consider (what is now fully admitted) that a large proportion of the Malayan is derived from that source, and that the names of many places in this and the neighbouring countries (such as Indrapura and Indragiri in Sumatra, Singapura at the extremity of the peninsula, and Sukapura and the mountain of Maha-meru in Java) are indisputably of Hindu origin. It is not my intention however to assign a precise etymology; but in order to show the general analogy to known Sanskrit terms it may be allowed to instance Samuder, the ancient name of the capital of the Carnatik, afterwards called Bider; Samudra-duta, which occurs in the Hetopadesa, as signifying the ambassador of the sea; the compound formed of su, good, and matra, measure; and more especially the word samantara, which implying a boundary, intermediate, or what lies between, might be thought to apply to the peculiar situation of an island intermediate between two oceans and two straits.

NOT ENTIRELY UNKNOWN TO THE NATIVES.

When on a former occasion it was asserted (and with too much confidence) that the name of Sumatra is unknown to the natives, who are ignorant of its being an island, and have no general name for it, the expression ought to have been confined to those natives with whom I had an opportunity of conversing, in the southern part of the west coast, where much genuineness of manners prevails, with little of the spirit of commercial enterprise or communication with other countries. But even in situations more favourable for acquiring knowledge I believe it will be found that the inhabitants of very large islands, and especially if surrounded by smaller ones, are accustomed to consider their own as terra firma, and to look to no other geographical distinction than that of the district or nation to which they belong. Accordingly we find that the more general names have commonly been given by foreigners, and, as the Arabians chose to call this island Al-rami or Lameri, so the Hindus appear to have named it Sumatra or Samantara.

MALAYAN NAMES FOR THE ISLAND.

Since that period however, having become much better acquainted with Malayan literature, and perused the writings of various parts of the peninsula and islands where the language is spoken and cultivated, I am enabled to say that Sumatra is well known amongst the eastern people and the better-informed of the natives themselves by the two names of Indalas and Pulo percha (or in the southern dialect Pritcho).

INDALAS.

Of the meaning or analogies of the former, which seems to have been applied to it chiefly by the neighbouring people of Java, I have not any conjecture, and only observe its resemblance (doubtless accidental) to the Arabian denomination of Spain or Andalusia. In one passage I find the Straits of Malacca termed the sea of Indalas, over which, we are gravely told, a bridge was thrown by Alexander the Great.

PERCHA.

The latter and more common name is from a Malayan word signifying fragments or tatters, and the application is whimsically explained by the condition of the sails of the vessel in which the island was circumnavigated for the first time; but it may with more plausibility be supposed to allude to the broken or intersected land for which the eastern coast is so remarkable. It will indeed be seen in the map that in the vicinity of what are called Rupat's Straits there is a particular place of this description named Pulo Percha, or the Broken Islands. As to the appellation of Pulo Ber-api, or Volcano Island, which has also occurred, it is too indefinite for a proper name in a region of the globe where the phenomenon is by no means rare or peculiar, and should rather be considered as a descriptive epithet.

MAGNITUDE.

In respect to magnitude, it ranks amongst the largest islands in the world; but its breadth throughout is determined with so little accuracy that any attempt to calculate its superficies must be liable to very considerable error. Like Great Britain it is broadest at the southern extremity, narrowing gradually to the north; and to this island it is perhaps in size more nearly allied than in shape.

MOUNTAINS.

A chain of mountains runs through its whole extent, the ranges being in many parts double and treble, but situated in general much nearer to the western than the opposite coast, being on the former seldom so much as twenty miles from the sea, whilst on the eastern side the extent of level country, in the broader part of the island, through which run the great rivers of Siak, Indragiri, Jambi, and Palembang, cannot be less than a hundred and fifty. The height of these mountains, though very great, is not sufficient to occasion their being covered with snow during any part of the year, as those in South America between the tropics are found to be. Mount Ophir,* or Gunong Pasaman, situated immediately under the equinoctial line, is supposed to be the highest visible from the sea, its summit being elevated thirteen thousand eight hundred and forty-two feet above that level; which is no more than two-thirds of the altitude the French astronomers have ascribed to the loftiest of the Andes, but somewhat exceeds that of the Peak of Tenerife.

(*Footnote. The following is the result of observations made by Mr. Robert Nairne of the height of Mount Ophir:

Height of the peak above the level of the sea, in feet: 13,842.

English miles: 2.6216.

Nautical miles: 2.26325.

Inland, nearly: 26 nautical miles.

Distance from Massang Point: 32 nautical miles.

Distance at sea before the peak is sunk under the horizon: 125 nautical miles.

Latitude of the peak: 0 degrees 6 minutes north.

A volcano mountain, south of Ophir, is short of that in height by: 1377 feet.

Inland, nearly 29 nautical miles.

In order to form a comparison I subjoin the height, as computed by mathematicians, of other mountains in different parts of the world:

Chimborazo, the highest of the Andes, 3220 toises or 20,633 English feet. Of this about 2400 feet from the summit are covered with eternal snow.

Carazon, ascended by the French astronomers: 15,800 English feet.

Peak of Tenerife. Feuille: 2270 toises or 13,265 feet.

Mount Blanc, Savoy. Sr. G. Shuckburgh: 15,662.

Mount Etna, Sr. G. Shuckburgh: 10,954.

Between these ridges of mountains are extensive plains, considerably elevated above the surface of the maritime lands, where the air is cool; and from this advantage they are esteemed the most eligible portion of the country, are consequently the best inhabited and the most cleared from woods, which elsewhere in general throughout Sumatra cover both hills and valleys with an eternal shade. Here too are found many large and beautiful lakes that extend at intervals through the heart of the country, and facilitate much the communication between the different parts, but their dimensions, situation, or direction, are very little known, though the natives make frequent mention of them in the accounts of their journeys. Those principally spoken of are: one of great extent but unascertained situation in the Batta country; one in the Korinchi country, lately visited by Mr. C. Campbel; and another in the Lampong country, extending towards Pasummah, navigated by boats of a large class with sails, and requires a day and night to effect the passage across it; which may be the case in the rainy season, as that part of the island through which the Tulang Bawang River flows is subject to extensive inundations, causing it to communicate with the river of the Palembang. In a journey made many years since by a son of the sultan of the latter place, to visit the English resident at Croee, he is said to have proceeded by the way of that lake. It is much to be regretted that the situation of so important a feature in the geography of the island should be at this day the subject of uncertain conjecture.

WATERFALLS.

Waterfalls and cascades are not uncommon, as may be supposed in a country of so uneven a surface as that of the western coast. A remarkable one descends from the north side of Mount Pugong. The island of Mansalar, lying off and affording shelter to the bay of Tappanuli, presents to the view a fall of very striking appearance, the reservoir of which the natives assert (in their fondness for the marvellous) to be a huge shell of the species called kima (Chama gigas) found in great quantities in that bay, as well as at New Guinea and other parts of the east.* At the bottom of this fall ships occasionally take in their water without being under the necessity of landing their casks; but such attempts are liable to extreme hazard. A ship from England (the Elgin) attracted by the appearance from sea of a small but beautiful cascade descending perpendicularly from the steep cliff, that, like an immense rampart, lines the seashore near Manna, sent a boat in order to procure fresh water; but she was lost in the surf, and the crew drowned.

(*Footnote. The largest I have seen was brought from Tappanuli by Mr. James Moore of Arno's Vale in the north of Ireland. It is 3 feet 3½ inches in its longest diameter, and 2 feet 1¼ inches across. One of the methods of taking them in deep water is by thrusting a long bamboo between the valves as they lie open, when, by the immediate closure which follows, they are made fast. The substance of the shell is perfectly white, several inches thick, is worked by the natives into arm-rings, and in the hands of our artists is found to take a polish equal to the finest statuary marble.)

RIVERS.

No country in the world is better supplied with water than the western coast of the island. Springs are found wherever they are sought for, and the rivers are innumerable; but they are in general too small and rapid for the purpose of navigation. The vicinity of the mountains to that side of the island occasions this profusion of rivulets, and at the same time the imperfections that attend them, by not allowing them space to accumulate to any considerable size. On the eastern coast the distance of the range of hills not only affords a larger scope for the course of the rivers before they disembogue, presents a greater surface for the receptacle of rain and vapours, and enables them to unite a greater number of subsidiary streams, but also renders the flux more steady and uniform by the extent of level space than where the torrent rolls more immediately from the mountains. But it is not to be understood that on the western side there are no large rivers. Kataun, Indrapura, Tabuyong, and Sinkel have a claim to that title, although inferior in size to Palembang, Jambi, Indragiri, and Siak. The latter derive also a material advantage from the shelter given to them by the peninsula of Malacca, and Borneo, Banca, and the other islands of the Archipelago, which, breaking the force of the sea, prevent the surf from forming those bars that choke the entrance of the south-western rivers, and render them impracticable to boats of any considerable draught of water. These labour too under this additional inconvenience that scarcely any except the largest run out to sea in a direct course. The continual action of the surf, more powerful than the ordinary force of the stream, throws up at their mouths a bank of sand, which in many instances has the effect of diverting their course to a direction parallel with the shore, between the cliffs and the beach, until the accumulated waters at length force their way wherever there is found the weakest resistance. In the southerly monsoon, when the surfs are usually highest, and the streams, from the dryness of the weather, least rapid, this parallel course is of the greatest extent; and Moco-moco River takes a course, at times, of two or three miles in this manner, before it mixes with the sea; but as the rivers swell with the rain they gradually remove obstructions and recover their natural channel.

AIR.

The heat of the air is by no means so intense as might be expected in a country occupying the middle of the torrid zone. It is more temperate than in many regions without the tropics, the thermometer, at the most sultry hour, which is about two in the afternoon, generally fluctuating between 82 and 85 degrees. I do not recollect to have ever seen it higher than 86 in the shade, at Fort Marlborough; although at Natal, in latitude 34 minutes north, it is not unfrequently at 87 and 88 degrees. At sunrise it is usually as low as 70; the sensation of cold however is much greater than this would seem to indicate, as it occasions shivering and a chattering of the teeth; doubtless from the greater relaxation of the body and openness of the pores in that climate; for the same temperature in England would be esteemed a considerable degree of warmth. These observations on the state of the air apply only to the districts near the sea-coast, where, from their comparatively low situation, and the greater compression of the atmosphere, the sun's rays operate more powerfully. Inland, as the country ascends, the degree of heat decreases rapidly, insomuch that beyond the first range of hills the inhabitants find it expedient to light fires in the morning, and continue them till the day is advanced, for the purpose of warming themselves; a practice unknown in the other parts of the island; and in the journal of Lieutenant Dare's expedition it appears that during one night's halt on the summit of a mountain, in the rainy season, he lost several of his party from the severity of the weather, whilst the thermometer was not lower than 40 degrees. To the cold also they attribute the backwardness in growth of the coconut-tree, which is sometimes twenty or thirty years in coming to perfection, and often fails to produce fruit. Situations are uniformly colder in proportion to their height above the level of the sea, unless where local circumstances, such as the neighbourhood of sandy plains, contribute to produce a contrary effect; but in Sumatra the coolness of the air is promoted by the quality of the soil, which is clayey, and the constant and strong verdure that prevails, which, by absorbing the sun's rays, prevents the effect of their reflection. The circumstance of the island being so narrow contributes also to its general temperateness, as wind directly or recently from the sea is seldom possessed of any violent degree of heat, usually acquired in passing over large tracts of land in the tropical climates. Frost, snow, and hail I believe to be unknown to the inhabitants. The hill-people in the country of Lampong speak indeed of a peculiar kind of rain that falls there, which some have supposed to be what we call sleet; but the fact is not sufficiently established. The atmosphere is in common more cloudy than in Europe, which is sensibly perceived from the infrequency of clear starlight nights. This may proceed from the greater rarefaction of the air occasioning the clouds to descend lower and become more opaque, or merely from the stronger heat exhaling from the land and sea a thicker and more plentiful vapour. The fog, called kabut by the natives, which is observed to rise every morning among the distant hills, is dense to a surprising degree; the extremities of it, even when near at hand, being perfectly defined; and it seldom is observed to disperse till about three hours after sunrise.

WATERSPOUT.

That extraordinary phenomenon, the waterspout, so well known to and described by navigators, frequently makes its appearance in these parts, and occasionally on shore. I had seen many at sea; but the largest and most distinct (from its proximity) that I had an opportunity of observing, presented itself to me whilst on horseback. I was so near to it that I could perceive what appeared to be an inward gyration, distinct from the volume surrounding it or body of the tube; but am aware that this might have been a deception of sight, and that it was the exterior part which actually revolved--as quiescent bodies seem to persons in quick motion, to recede in a contrary direction. Like other waterspouts it was sometimes perpendicular and sometimes curved, like the pipe of a still-head, its course tending in a direction from Bencoolen Bay across the peninsula on which the English settlement stands; but before it reached the sea on the other side it diminished by degrees, as if from want of the supplies that should be furnished by its proper element, and collected itself into the cloud from which it depended, without any consequent fall of water or destructive effect. The whole operation we may presume to be of the nature of a whirlwind, and the violent ebullition in that part of the sea to which the lower extremity of the tube points to be a corresponding effect to the agitation of the leaves or sand on shore, which in some instances are raised to a vast height; but in the formation of the waterspout the rotatory motion of the wind acts not only upon the surface of the land or sea, but also upon the overhanging cloud, and seems to draw it downwards.

THUNDER AND LIGHTNING.

Thunder and lightning are there so very frequent as scarcely to attract the attention of persons long resident in the country. During the north-west monsoon the explosions are extremely violent; the forked lightning shoots in all directions, and the whole sky seems on fire, whilst the ground is agitated in a degree little inferior to the motion of a slight earthquake. In the south-east monsoon the lightning is more constant, but the coruscations are less fierce or bright, and the thunder is scarcely audible. It would seem that the consequences of these awful meteors are not so fatal there as in Europe, few instances occurring of lives being lost or buildings destroyed by the explosions, although electrical conductors have never been employed. Perhaps the paucity of inhabitants in proportion to the extent of country and the unsubstantial materials of the houses may contribute to this observation. I have seen some trees, however, that have been shattered in Sumatra by the action of lightning.*

(*Footnote. Since the above was written accounts have been received that a magazine at Fort Marlborough, containing four hundred barrels of powder, was fired by lightning and blown up on the 18th of March 1782.)

MONSOONS.

The causes which produce a successive variety of seasons in the parts of the earth without the tropics, having no relation or respect to the region of the torrid zone, a different order takes place there, and the year is distinguished into two divisions, usually called the rainy and dry monsoons or seasons, from the weather peculiar to each. In the several parts of India these monsoons are governed by various particular laws in regard to the time of their commencement, period of duration, circumstances attending their change, and direction of the prevailing wind according to the nature and situation of the lands and coasts where their influence is felt. The farther peninsula of India, where the kingdom of Siam lies, experiences at the same time the effects of opposite seasons; the western side, in the Bay of Bengal, being exposed for half the year to continual rains, whilst on the eastern side the finest weather is enjoyed; and so on the different coasts of Indostan the monsoons exert their influence alternately; the one remaining serene and undisturbed whilst the other is agitated by storms. Along the coast of Coromandel the change, or breaking up of the monsoon as it is called, is frequently attended with the most violent gales of wind.

On the west coast of Sumatra, southward of the equinoctial, the south-east monsoon or dry season begins about May and slackens in September: the north-west monsoon begins about November, and the hard rains cease about March. The monsoons for the most part commence and leave off gradually there; the months of April and May, October and November generally affording weather and winds variable and uncertain.

CAUSE OF THE MONSOONS.

The causes of these periodical winds have been investigated by several able naturalists, whose systems, however, do not entirely correspond either in the principles laid down or in their application to the effects known to be produced in different parts of the globe. I shall summarily mention what appear to be the most evident, or probable at least, among the general laws, or inferences, which have been deduced from the examination of this subject. If the sea were perfectly uninterrupted and free from the irregular influence of lands, a perpetual easterly wind would prevail in all that space comprehended between the twenty-eighth or thirteenth degrees of north and south latitude. This is primarily occasioned by the diurnal revolution of the earth upon its axis from west to east; but whether through the operation of the sun, proceeding westward, upon the atmospheric fluid, or the rapidity of revolution of the solid body, which leaves behind it that fluid with which it is surrounded, and thereby causes it virtually to recede in a contrary direction; or whether these principles cooperate, or unequally oppose each other, as has been ingeniously contended, I shall not take upon me to decide. It is sufficient to say that such an effect appears to be the first general law of the tropical winds. Whatever may be the degree of the sun's influence upon the atmosphere in his transient diurnal course, it cannot be doubted but that, in regard to his station in the path of the ecliptic, his power is considerable. Towards that region of the air which is rarefied by the more immediate presence of the heat, the colder and denser parts will naturally flow. Consequently from about, and a few degrees beyond, the tropics, on either side, the air tends towards the equator; and, combining with the general eastern current before mentioned, produces (or would, if the surface were uniform) a north-east wind in the northern division, and a south-east in the southern; varying in the extent of its course as the sun happens to be more or less remote at the time. These are denominated the trade-winds, and are the subject of the second general observation. It is evident that, with respect to the middle space between the tropics, those parts which at one season of the year lie to the northward of the sun, are, during another, to the southward of him; and of course that an alteration of the effects last described must take place, according to the relative situation of the luminary; or in other words, that the principle which causes at one time a north-east wind to prevail at any particular spot in those latitudes must, when the circumstances are changed, occasion a south-east wind. Such may be esteemed the outline of the periodical winds, which undoubtedly depend upon the alternate course of the sun northwards and southwards; and this I state as the third general law. But although this may be conformable with experience in extensive oceans, yet, in the vicinity of continents and great islands, deviations are remarked that almost seem to overturn the principle. Along the western coast of Africa and in some parts of the Indian seas, the periodical winds, or monsoons as they are termed in the latter, blow from the west-north-west and south-west, according to the situation, extent, and nature of the nearest lands; the effect of which upon the incumbent atmosphere, when heated by the sun at those seasons in which he is vertical, is prodigious, and possibly superior to that of any other cause which contributes to the production or direction of wind. To trace the operation of this irregular principle through the several winds prevalent in India, and their periodical failures and changes, would prove an intricate but, I conceive, by no means an impossible task.* It is foreign however to my present purpose, and I shall only observe that the north-east monsoon is changed, on the western coast of Sumatra, to north-west or west-north-west by the influence of the land. During the south-east monsoon the wind is found to blow there, between that point and south. Whilst the sun continues near the equator the winds are variable, nor is their direction fixed till he has advanced several degrees towards the tropic: and this is the cause of the monsoons usually setting in, as I have observed, about May and November, instead of the equinoctial months.
