The map of Java which accompanies this work has been drawn principally from actual surveys, many of which were made by order of the British Government on the island. The first map of Java which was presented to the public, and from which nearly all those, which have subsequently been engraved, are copies, was published by Valentyn,[16] and consists of seven sheets. As, at that period, little more was known of the island by the Dutch than some parts of the coast, the country in the immediate vicinity of their capital, with perhaps the province of Bantam, the author had no materials for making a map of the whole island, which could pretend to much authority or value. Most of the land in the immediate vicinity of Batavia having been sold to Europeans, was of necessity surveyed, in order to ascertain the different boundaries; but it was only a short time before the arrival of Marshal Daendels, in 1808, that any steps appear to have been taken by the local authorities, to procure correct statistical and topographical information of the other more important districts of the island. Something to this effect was done during the administration of Mr. Engelhard, late Governor of the North-east Coast, but it was only during the government of the Marshal that these objects were pursued with much energy or success.
At the period of the arrival of the English, topographical surveys of Semárang and several of the eastern districts had been completed; and although somewhat deficient in accuracy of measurement and neatness of execution, yet as they appeared sufficiently correct for many valuable purposes, and as the Government was anxious to obtain, without loss of time, a better acquaintance with the geography of the country, it was determined to make some sacrifice of accuracy to the considerations of economy and expedition, and to survey the other districts upon the same plan. While these surveys were in progress, the territorial interest which the European government obtained in the central provinces, induced them to turn their attention to the improvements of which the Solo River might be susceptible. This river, the most considerable in the island, passes through Súra-kérta, the capital of the Susuhúnan, or (as he is termed by Europeans) Emperor of Java, and discharges itself into the sea near Grésik. An actual survey was accordingly made by a British officer of experience, particularly instructed to ascertain how far it might be practicable to improve its navigation by the aid of artificial cuts and dams.
A greater object soon called for more extensive measures. When it was determined to introduce an entirely new system of internal management, by the abolition of feudal service, and the establishment of a more permanent property in the soil, it was deemed essential that a detailed survey should be made of the different districts successively, in which the new system was to be introduced. This was intended to form the basis of a general agricultural survey of the country, then about to be made. In several of these districts this detailed survey has been completed; and, with the exception of the provinces still under native jurisdiction, and called Native Provinces, nearly the whole of the land on Java, not in a state of absolute forest, has been measured with more or less accuracy. Of the native provinces but a very small part has been actually surveyed; with regard to the rest, the materials from which the present map is taken, were principally obtained from observation made during occasional routes through them. The southern division of Bantam being principally forest, has not been actually surveyed; neither has the island of Madura been yet surveyed by Europeans: the eastern part of it was measured by the natives, and it was principally upon their authority that the map now presented of that island was drawn. The best charts of both the north and south coast have been consulted. The three harbours of Wyn Coops Bay, Cheláchap, and Pachítan, on the latter, are laid down from actual survey, as well as the entrance to the harbour of Surabáya. On the whole, therefore, although the map now engraved is far from perfect, and of course suffers from the reduction necessary to adapt it to the rest of the work, it is presumed that it will aid the reader in most of the geographical objects to which this volume will refer, and that its superiority over those that have previously appeared is such as to justify its publication.
The length of Java, in a straight line drawn between its extreme points, (Java Head, and the south-east point of the island) is five hundred and seventy-five geographical, equal to six hundred and sixty-six statute miles: its breadth varies from one hundred and seventeen geographical, or one hundred and thirty-five and a half statute miles (between the south-west point of Pachítan bay and the north point of Japára) to forty-eight geographical or fifty-six statute miles, (between the mouth of the Seráyu river and the Marabáya, five degrees east of Tegál);[17] and it is estimated to contain an area of about fifty thousand statute miles.
Numerous small islands are scattered in its immediate vicinity, particularly along the northern coast, and contribute, with the projecting points and headlands inclosing the different bays, to form harbours of various capacities. The most important of these islands is that of Madúra, which is separated from the main land of Java by a strait in one part not more than a mile broad, and serves to form the important harbour of Surabáya. This island has the appearance of being a continuation of the main land of Java, and having been long subjected to the same political authority, has generally formed one of the provinces of the Javan empire. In length Madúra is about seventy-nine geographical, or ninety-one and a half statute miles; and its narrowest part is about twenty-seven geographical, or thirty-one and a quarter statute miles. The small islands lying to the east of it are considered as its dependencies.
The form of Java is chiefly remarkable for the rectangularity of its outline, which is such that the island might be divided into five or six parts, each a rectangular parallelogram drawn by an unsteady hand. Its western and northern coasts abound with bays and inlets. The outline of Madúra is more regular, especially on the northern coast.
The coast from Bantam to the river Chi-mánok, about two degrees in length on the north, is nearly parallel to that which extends from Wyn Coops Bay to a point about twenty miles west of Núsa kambúng'an, the breadth throughout being about seventy-eight geographical miles; and from the same point to the river Manchíngan, a distance of about one degree and three-quarters, the coast is nearly parallel to that which lies between Chéribon and Semárang, the breadth throughout being about fifty-seven geographical miles. From the west point of Japára to point Pángka on the north, distant from it about two degrees, and along the corresponding coast on the south, the average breadth is seventy-three geographical miles; and from Surabáya to the north-east point of the island, distant about one degree and a half, and along the south coast opposite to it, the average breadth is forty-five geographical miles.
At the time when Europeans first visited Java, the whole of the island acknowledged the supremacy of one sovereign: but there was a period in its history when it was nearly equally divided under the independent administration of two powers, one established in the eastern, and the other in the western districts; and as there is a marked distinction between the descendants of these two nations, the most general division of the country is still into the western and eastern districts, to the latter of which alone the term Java is applied by the natives. They are separated by the river Losári, which forms the boundary between Chéribon and Brébes: and all the western, the northern, with a few of the inland districts and the Island of Madúra, are under the immediate authority and administration of the European government. The rest of the island remains subject to the native princes, and on that account is designated on the map and elsewhere, with more regard to convenience than correctness of language, as the Native Provinces.
The provinces under European authority have latterly been divided into fifteen residencies, or separate administrations, exclusive of the seat of government, which, as they will be frequently referred to in the course of this work, it may be convenient to notice in this place.
Commencing from the west, the province, or as it is usually termed, the kingdom of Bantam (properly Bántan) occupies the first place. This extensive province forms a large portion of the island. It is washed on three sides by the sea. At the east it joins with the environs and highlands of Batavia and the district of Chi-ánjur, and on the west it is bounded by the Straits of Sunda; and in this quarter comprises dependant islands scattered along its shore, and the two harbours of Mew and Merák, which, with other bays, deeply indent the coast. Bantam, the native capital of this province, has been latterly deserted by the European establishment for Sírang (commonly called Ceram), an elevated and healthy station about seven miles further inland.
