"The island of Java contains more volcanoes, active and extinct, than any other known district of equal extent. They are about forty-five in number, and many of them exhibit most beautiful examples of the volcanic cone on a large scale, single or double, with entire or truncated summits, and averaging 10,000 feet high."[20]
Thirdly, not only did Sumatra, Java, and Borneo once form part of the continent of Asia, but the subsidence of land which caused their separation from the continent, and from each other, is of very recent date—recent, that is, in the scale of geological eras. This is shown by the fact that the separating seas are so shallow that to-day ships can anchor anywhere in them. We shall, therefore, expect a strong similarity, almost amounting to a complete identity, to exist between the animals and plants of Sumatra, Java, and Borneo and those of Southern India, Burmah, and the Malay Peninsular. Such, according to Mr. Wallace, is the fact.
"The elephant and tapir of Sumatra and Borneo, the rhinoceros of Sumatra and the allied species of Java, the wild cattle of Borneo, and the kind long supposed to be peculiar to Java, are now all known to inhabit some part or other of Southern Asia.... Birds and insects illustrate the same view, for every family and almost every genus of these groups found in any of the islands occurs also in the Asiatic continent, and in a great number of cases the species are exactly identical."
In addition to the rhinoceros and wild cattle mentioned above, the wild animals of Java include the jackal, the tiger, and several species of monkeys. Snakes and alligators are also to be found in the island. There is a good supply of domestic animals with the exception of sheep. This useful animal was so entirely unknown to the natives, that when the Dutch attempted to introduce it into the island it was necessary to find a name for it. It was accordingly called a "Dutch goat;" nor is there at the present time any other term in the Malay language by which the animal can be designated. I have already spoken of the utility of the Javan horses. They are imported in large numbers from the neighbouring island of Sandalwood, and great attention is being paid to the production of country-breds. An attempt is also being made to improve the breed by the importation of English and Australian thoroughbreds. I was also informed that in recent years a number of cattle had been introduced from India. As in most Eastern countries, the ox is used in Java for drawing carts and for other agricultural purposes; but the buffalo is the most valuable of all animals to the natives, by whom it is especially employed in the cultivation of the ricefields. The only dangerous animal is the tiger, and the sport of tiger-hunting still forms one of the recreations of the native princes.
The birds of Java are distinguished for their variety and for the rich plumage with which they are adorned. During a single month passed in Ardjoeno, a mountain situated in the regency of Paseroean, in the east of the island, Mr. Wallace collected ninety-eight species of birds. Among these he mentions the Javan peacock, of which he obtained two specimens more than seven feet long; the jungle fowl (Gallus furcatus); the jungle cock (Gallus bankiva), called by the natives bekéko; various species of woodpeckers and kingfishers; a hornbill (Buceros lunatus) more than four feet long; and a "pretty little lorikeet (Loriculus pusillus) scarcely more than as many inches." When he visited the west of the island, he found still more valuable specimens in the Preanger regencies, twenty miles south of Buitenzorg. Among the mountains of this neighbourhood, and at an elevation of 4000 feet, he collected in a fortnight forty species of birds, "almost all of which were peculiar to the Javanese fauna." In these were included the "elegant yellow-and-green trogon (Harpactes Reinwardti); the gorgeous little minivet flycatcher (Pericrocotus miniatus), which looks like a flame of fire as it flutters among the bushes; and the rare and curious black-and-crimson oriole (Analcipus sanguinolentus)." Mr. Wallace also speaks of the rare and beautiful butterflies which he captured here. In particular he secured a specimen of the calliper butterfly, "remarkable for having on each hind wing two curved tails like a pair of callipers."
It is in this neighbourhood that the large Javan wood-pigeons which I saw at Tji Wangi are to be found. As they are excellent eating, they are shot by the planters, though it is often difficult to get within range of them owing to the height of the rosamala trees in which they settle.
There are certain characteristic developments of plant-life which arrest the attention of the traveller in Java.
In the towns he cannot fail to be impressed with the large-leaved and gorgeously coloured shrubs which surround the houses of the European residents; he will notice, too, that the streets and open spaces are planted with waringin and tamarind trees, and when he travels into the interior he will find that the roads which traverse the island are still lined by the same trees. Of these the former is a species of ficus; the latter, the tamarind, has been introduced from Madagascar. Towards the end of the year it is covered with orange blossoms, which finally develop into a somewhat acid fruit. In the country the dwellings of the Javan peasants are almost universally surrounded by palms, bananas, and bamboos. While the palms and bananas supply the native with fruit, from the bamboo he has learnt to make numberless useful articles, ranging from a house or a boat to a drinking-vessel or a musical instrument. Cooking-utensils, baskets, hats, and all manner of tools are constructed out of the material provided by this useful tree. While I was staying at a friend's house at Weltevreden I had a singular illustration of the variety of uses to which the bamboo could be put by observing the method of cutting the grass adopted by a native gardener. He was squatting on the ground, and had by his side about half a dozen sections into which he had split some bamboo rods about two feet in length. These he rapidly passed over the grass backwards and forwards with a semicircular sweep, and their sharp edges mowed the grass down as cleanly as the blade of a scythe. In this way he cleared a space around him, and, gradually advancing, eventually trimmed off the whole plot of grass.
The tropical forests, again, are characterized by a remarkable uniformity and sombreness which gives them an aspect quite unlike that of European woods. The vast cylindrical trunks of the great forest trees, rising like pillars from the midst of ferns and lesser growths, support a lofty roof of leaves. Beneath this screen innumerable forms of plant-life develop without let or hindrance, and the whole abundant foliage is bound into an inextricable mass by parasites and creepers. On every side the eye is met by one monotonous tone of verdure, for the supremely favourable conditions for plant-life which obtains tend to produce a total effect, not of variety, but of sameness.
One of the most interesting facts connected with the Javan flora is the appearance of European flowers upon the higher levels of the mountains. The phenomenon is the more remarkable in the face of the consideration that the seeds of such flowers are so heavy, and the distance from their present habitat so great, as to negative the supposition that they have been carried by the wind; nor can their presence be satisfactorily referred to the agency of birds.
