On the other hand, the soil is proverbially fertile. The chief products are best exhibited in connection with the four botanical zones into which Junghuhn has divided the island according to elevation:
| I. | From the seaboard to 2000 feet. | Tropical. | Rice, sugar, cinnamon, cotton, maize. |
| II. | From 2000 feet to 4500 feet. | Moderately hot. | Coffee, tea, cinchona, sugar-palm. |
| III. | From 4500 feet to 7500 feet. | Moderately cool. | Indian corn, tobacco, cabbage, potatoes. |
| IV. | From 7500 feet to 12,000 feet. | Cold. | European flora. |
The climate varies in accordance with these zones. Observations made at Batavia (on the coast), the only place where a record covering a sufficient period has been kept, give a mean of 78.69° for a period of twelve years. The monthly mean shows a variation of only two degrees. The period from April to November, when the south-east trade winds prevail, called the dry or east monsoon, is slightly warmer than the remaining six months which make up the rainy season. The heaviest rainfall is in the months of December, January, and February. The chief characteristic of the climate of Java is, therefore, not so much its heat as its equability: it is rarely wet all day long even in the wet season, and at least one shower may be expected each day in the dry.
In spite of its great heat Java is generally healthy, and, in cases of simple bronchitis, the climate is positively helpful. Of course the mountain districts are preferable to the plains, but in the ordinary routes traversed by travellers there are no conditions to be encountered which are adverse to persons in the enjoyment of ordinary health. Buitenzorg (close to Batavia), the summer residence of the Governor-General, a place which is to Dutch India what Simla is to British India, is especially healthy, being some seven hundred feet above sea-level. Tosari, again, in the eastern part of the island, is a recognized sanatorium. It has a capital hotel, and lies at an elevation of six thousand feet above sea-level. This latter place is easily reached in one day from Soerabaia; and close by is Mount Bromo, one of the most active volcanoes in Java, and one which is always covered with smoke. A three-mile walk will give the visitor an opportunity of seeing the boiling crater—a magnificent spectacle. Mount S'meroe, the highest mountain in Java (12,000 feet), is also in the neighbourhood.
The best time to travel is the dry season, April to November, when the nights are cooler and the weather brighter; and, of course, in travelling by carriage, arrangements should be made to avoid proceeding during the hottest part of the day as much as possible.
The Dutch are nothing if they are not methodical, and in order to travel in Java certain formalities, which at first sight appear somewhat formidable, but which are really matters of form, have to be gone through. Any person intending to remain in the island for more than twenty-four hours must register his name with the police, and give them particulars of his age, birthplace, profession, last place of residence, the ship in which he arrived, and the name of its captain. He thereupon receives a document entitled Toetlakings-kaart ("admission ticket"), which states that the person so named and described arrived at a certain date, "with the intention of residing in Netherlands India," and that he is permitted, "by authority of the ordinance of March 12, 1872, to reside in any of the chief harbours or ports open for general trade, and also at Buitenzorg." It is signed by the Assistant-Resident of Batavia. This "admission-ticket" is not sufficient to authorize the new arrival to travel in the interior. For this purpose a second and still more imposing document must be obtained. This is an extract from the register of "decisions" of the Governor-General, and is to the effect that the petition of the undersigned So-and-so has been read, and "that the Governor-General has been pleased to grant him permission to travel for six months in Java."
If the visitor wishes to enjoy any sport he will require a third document, signed by the Resident, to entitle him to "import the following weapon and ammunition, namely," his gun, "which is intended for his own use." It will be a relief to the reader to know that in my own case the documents confirming the grant of all these privileges were obtained at the cost of half a crown for stamps.
Batavia, the capital of Java and the seat of government of the Dutch possessions in the East, is distant two hundred and fifty miles from Samarang, and four hundred from Soerabaia, the ports which respectively "tap" the populous central and eastern districts. While these two latter towns are connected by rail with each other, communication with Batavia is maintained at present by steamboats and post-carriages, since there is a break of one hundred and twenty miles—from Garoet, the terminus of the western railway, to Tjilatjap, a port on the southern coast—in the trunk line which is eventually to unite the whole island. Batavia, however, in spite of this drawback, is the natural starting-point for the visitor. In the first place, it is the port of call of the principal steamboat companies which connect Java with Australia, British India, China, and Europe; and in the next, being the seat of government and containing the chief political and scientific authorities, it is the centre from which information and assistance of all kinds may be obtained. In particular, I would recommend a visit to the museum of antiquities at Batavia as an introduction to the study not only of the Hindu remains, but also of the native industries and manner of life.
The subjects of special interest in Java may be grouped under five heads—the Hindu antiquities, the native towns, the plantations, tropical plant-life, and sport. In the case of the three latter, the several neighbourhoods required to be visited are easily accessible from Batavia by the western railway. Soekaboemi, the centre of the coffee and cinchona plantations, and the head-quarters of the Planters' Association, is fifty miles distant. Buitenzorg, with its famous botanical gardens, is within an hour and a half's journey. Here, in the various Government gardens and plantations, the plant-life of the whole Malay Archipelago is conveniently exhibited, both in its scientific and industrial aspects, and a strangers' laboratory is specially provided for scientific visitors. The Preanger Regencies—the best place for sport—may be described roughly as occupying the southern half of the western portion of the island. The chief towns of this district—Tjandjoer, Bandong, and Garoet—are all connected with Batavia by the same line of railway. Of these, Tjandjoer is the residence of the native prince, the Regent of Tjandjoer, who is the chief patron of horse-racing in Java.
