I have often travelled on foot through the jungle, accompanied by Dyaks carrying my baggage. We have walked in single file on these trunks of trees, and have listened to the weird jungle sounds—the creaking of giant trees, the strange cries of insects, or birds, or monkeys. And sometimes in the gathering darkness, when the storm-clouds have hurried overhead and the winds shrieked through the tree-tops in fierce discord, ruthlessly twanging the harp-strings of Nature, I have understood why it is that the Dyaks believe that the lone forests are inhabited by the spirits of the wind and the rivers, of the mountains and the trees. No one can adequately realize the Equatorial Bornean jungle until he sees it in all its wonder—the heated steamy stillness broken by weird sounds, the colossal trees, the birds with brilliant plumage, and the infinite variety of monkeys among the branches, sitting, hanging by hands or tails, leaping, grimacing, jabbering, as they see the strange sight of human beings invading their domains. What are the wild animals that the traveller is likely to meet as he walks through the jungle? The animal life of Borneo is akin to that of Sumatra or Java, but with certain differences. Borneo is free from tigers, and this is fortunate, for travelling through the forests would be dangerous indeed if tigers were likely to be encountered. The only wild animals to be met with are the small and comparatively harmless tree-tiger, and the small brown honey-bear, but neither of them is much feared. There are, of course, ferocious crocodiles in the rivers, and many varieties of snakes, varying in size from the python downwards. But the cobra, so much dreaded in India, is not met with in Borneo, and death from a snake-bite is very rare. The elephant and the rhinoceros seem to be confined to the north end of the island. There is the great man-like ape—the _orang-utan_, or _maias_, as it is called by the Dyaks. It is only found in a limited area, in the territory between the Batang Lupar and the Rejang Rivers. As a rule, this animal does not exceed the height of four feet two inches, though there are stories told of its attaining a far greater size. The height, however, gives a poor idea of the animal’s bulk and strength. The body is as large as that of an average man, but the legs are extremely short. Its arms are of great length, and measure over seven feet in spread. The whole body is covered with long red hair. It rarely attacks man, but when provoked is very ferocious, and as its strength is very great, it is a foe not to be despised. There are numerous wild boars in the jungle, but they never attack the traveller, and are not a source of danger.
