JAVA


irregularities. On the whole, the east monsoon blows steadily for a longer period than the west. The velocity of the wind is much less than in Europe—not more in the annual mean at Batavia than 3 ft. per second, against 12 to 18 ft. in Europe. The highest velocity ever observed at Batavia was 25 ft. Wind-storms are rare and hardly ever cyclonic. There are as a matter of course a large number of purely local winds, some of them of a very peculiar kind, but few of these have been scientifically dealt with. Thunder-storms are extremely frequent; but the loss of life from lightning is probably diminished by the fact that the palm-trees are excellent conductors. At night the air is almost invariably still. The average rainfall at Batavia is 72.28 in. per annum, of which 51.49 in. are contributed by the west monsoon. The amount varies considerably from year to year: in 1889, 1891 and 1897 there were about 47.24 in.; in 1868 and 1877 nearly 51.17, and in 1872 and 1882 no less than 94.8. There are no long tracts of unbroken rainfall and no long periods of continuous drought. The rainfall is heaviest in January, but it rains only for about one-seventh of the time. Next in order come February, March and December. August, the driest month, has from three to five days of rain, though the amount is usually less than an inch and not more than one and a half inches. The popular description of the rain falling not in drops but streams was proved erroneous by J. Wiesner’s careful observations (see Kais. Akad. d. Wiss. Math. Naturw. Cl. Bd. xiv., Vienna, 1895), which have been confirmed by A. Woeikof (“Regensintensität und Regendauer in Batavia” in Z. für Met., 1907). The greatest rainfall recorded in an hour (4.5 in.) is enormously exceeded by records even in Europe. From observations taken for the meteorological authorities at a very considerable number of stations, J. H. Boeseken constructed a map in 1900 (Tijdschr. v. h. Kon. Ned. Aardr. Gen., 1900; reproduced in Veth, Java, iii. 1903). Among the outstanding facts are the following. The south coasts of both eastern and middle Java have a much heavier rainfall than the north. Majalenka has an annual fall of 175 in. In western Java the maximal district consists of a great ring of mountains from Salak and Gedeh in the west to Galung-gung in the east, while the enclosed plateau-region of Chanjur Bandung and Garut are not much different from the seaboard. The whole of middle Java, with the exception of the north coast, has a heavy rainfall. At Chilachap the annual rainfall is 151.43 in., 87.8 in. of which is brought by the south-east monsoon. The great belt which includes the Slamet and the Dieng, and the country on the south coast between Chilachap and Parigi, are maximal. In comparison the whole of eastern Java, with the exception of the mountains from Wilis eastward to Ijen, has a low record which reaches its lowest along the north coast.[1]

Fauna.—In respect of its fauna Java differs from Borneo, Sumatra and the Malay Peninsula far more than these differ among themselves; and, at the same time, it shows a close resemblance to the Malay Peninsula, on the one hand, and to the Himalayas on the other. Of the 176 mammals of the whole Indo-Malayan region the greater number occur in Java. Of these 41 are found on the continent of Asia, 8 are common to Java and Borneo, and 6 are common to Java and Sumatra (see M. Weber, Das Indo-Malay Archipelago und die Geschichte seiner Thierwelt, Jena, 1902). No genus and only a few species are confined to the island. Of the land-birds only a small proportion are peculiar. The elephant, the tapir, the bear, and various other genera found in the rest of the region are altogether absent. The Javanese rhinoceros (Rhinoceros sundaicus; sarak in Javanese, badak in Sundanese), the largest of the mammals on the island, differs from that of Sumatra in having one horn instead of two. It ranges over the highest mountains, and its regular paths, worn into deep channels, may be traced up the steepest slopes and round the rims of even active volcanoes. Two species of wild swine, Sus vittatus and Sus verrucosus, are exceedingly abundant, the former in the hot, the latter in the temperate, region; and their depredations are the cause of much loss to the natives, who, however, being Mahommedans, to whom pork is abhorrent, do not hunt them for the sake of their flesh. Not much less than the rhinoceros is the banteng (Bibos banteng or sundaicus) found in all the uninhabited districts between 2000 and 7000 ft. of elevation. The kidang or muntjak (Cervulus muntjac) and the rusa or russa (Rusa hippelaphus or Russa russa) are the representatives of the deer kind. The former is a delicate little creature occurring singly or in pairs both in the mountains and in the coast districts; the latter lives in herds of fifty to a hundred in the grassy opens, giving excellent sport to the native hunters. Another species (Russa kuhlii) exists in Bavian. The kantjil (Tragulus javanicus) is a small creature allied to the musk-deer but forming a genus by itself. It lives in the high woods, for the most part singly, seldom in pairs. It is one of the most peculiar of the Javanese mammals. The royal tiger, the same species as that of India, is still common enough to make a tiger-hunt a characteristic Javanese scene. The leopard (Felis pardus) is frequent in the warm regions and often ascends to considerable altitudes. Black specimens occasionally occur, but the spots are visible on inspection; and the fact that in the Amsterdam zoological gardens a black leopard had one of its cubs black and the other normally spotted shows that this is only a case of melanism. In the tree-tops the birds find a dangerous enemy in the matjan rembak, or wild cat (Felis minuta), about the size of a common cat. The dog tribe is represented by the fox-like adjag (Cuon or Canis sutilans) which hunts in ferocious packs; and by a wild dog, Canis tenggeranus, if this is not now exterminated. The Cheiroptera hold a prominent place in the fauna, the principal genera being Pteropus, Cynonycteris, Cynopterus and Macroglossus. Remarkable especially for size is the kalong, or flying fox, Pteropus edulis, a fruit-eating bat, which may be seen hanging during the day in black clusters asleep on the trees, and in the evening hastening in long lines to the favourite feeding grounds in the forest. The damage these do to the young coco-nut trees, the maize and the sugar-palms leads the natives to snare and shoot them; and their flesh is a favourite food with Europeans, who prefer to shoot them by night as, if shot by day, they often cling after death to the branches. Smaller kinds of bats are most abundant, perhaps the commonest being Scotophilus Temminckii. In certain places they congregate in myriads, like sea-fowl on the cliffs, and their excrement produces extensive guano deposits utilized by the people of Surakarta and Madiun. The creature known to the Europeans as the flying-cat and to the natives as the kubin is the Galeopithecus volans or variagatus—a sort of transition from the bats to the lemuroids. Of these last Java has several species held in awe by the natives for their supposed power of fascination. The apes are represented by the wou-wou (Hylobates leuciscus), the lutung, and kowi (Semnopithecus maurus and pyrrhus), the surili (Semnopithecus mitratus), and the munyuk (Cercocebus, or Macacus, cynamolgos), the most generally distributed of all. From sunrise to sunset the wou-wou makes its presence known, especially in the second zone where it congregates in the trees, by its strange cry, at times harsh and cacophonous, at times weird and pathetic. The lutung or black ape also prefers the temperate region, though it is met with as high as 7000 ft. above the sea and as low as 2000. The Cercocebus or grey ape keeps for the most part to the warm coast lands. Rats (including the brown Norway rat, often called Mus javanicus, as if it were a native; a great plague); mice in great variety; porcupines (Acanthion javanicum); squirrels (five species) and flying squirrels (four species) represent the rodents. A hare, Lepus nigricollis, originally from Ceylon, has a very limited habitat; the Insectivora comprise a shrew-mouse (Rachyura indica), two species of tupaya and Hylomys suillus peculiar to Java and Sumatra. The nearest relation to the bears is Arctictis binturong. Mydaus meliceps and Helictis orientalis represent the badgers. In the upper part of the mountains occurs Mustela Henrici, and an otter (Aonyx leptonyx) in the streams of the hot zone. The coffee rat (Paradoxurus hermaphroditus), a civet cat (Viverricida indica), the Javanese ichneumon (Herpestes javanicus), and Priodon gracilis may also be mentioned.

In 1820, 176 species of birds were known in Java; by 1900 Vorderman and O. Finsch knew 410. Many of these are, of course, rare and occupy a limited habitat far from the haunts of man. Others exist in myriads and are characteristic features in the landscape. Water-fowl of many kinds, ducks, geese, storks, pelicans, &c., give life to sea-shore and lake, river and marsh. Snipe-shooting is a favourite sport. Common night-birds are the owl (Strix flammea) and the goat-sucker (Caprimulgus affinis). Three species of hornbill, the year-bird of the older travellers (Buceros plicatus, lunatus and albirostris) live in the tall trees of the forest zone. The Javanese peacock is a distinct species (Pavo muticus or spiciferus), and even exceeds the well-known Indian species in the splendour of its plumage. Gallus Bankiva is famous as the reputed parent of all barn-door fowls; Gallus furcatus is an exquisitely beautiful bird and can be trained for cock-fighting. Of parrots two species only are known: Palaeornis Alexandri or javanicus and the pretty little grass-green Curyllis pusilla, peculiar to Java. As talkers and mimics they are beaten by the Gracula javanensis, a favourite cage-bird with the natives. A cuckoo, Chrysococcyx basalis, may be heard in the second zone. The grass-fields are the foraging-grounds of swarms of weaver-birds (Plocula javanensis and Ploccus baya). They lay nearly as heavy a toll on the rice-fields as the gelatiks (Munia oryzivora), which are everywhere the rice-growers’ principal foe. Hawks and falcons make both an easy prey. The Nictuarinas or honey-birds (eight species) take the place of the humming-bird, which they rival in beauty and diminutiveness, ranging from the lowlands to an altitude of 4000 ft. In the upper regions the birds, like the plants, are more like those of Europe, and some of them—notably the kanchilan (Hyloterpe Philomela)—are remarkable for their song. The edible-nest swallow (Collocalia fuciphaga) builds in caves in many parts of the island.[2]

As far back as 1859 P. Bleeker credited Java with eleven hundred species of fish; and naturalists are perpetually adding to the number.[3] In splendour and grotesqueness of colouring many kinds, as is well known, look rather like birds than fish. In the neighbourhood of Batavia about three hundred and eighty species are used as food by the natives and the Chinese, who have added to the number by the introduction of the goldfish, which reaches a great size. The sea fish most prized by Europeans is Lates calcarifer (a perch). Of more than one hundred species of snakes about twenty-four species
