The orang is a slow and deliberate climber. He is particularly careful about his feet, and seems much more sensitive to any injury to them than is the case with other apes. In climbing he alternately uses one hand and one foot, or else, as soon as he has taken a firm hold with his hands, he draws up both feet together. In his passage from one tree to another, he always looks out for a place where two branches come close together, or intertwine. Even when hotly pursued, he displays wonderful caution, trying the strength of the branches, and pressing them down by the weight of his body, so as to make a bridge from tree to tree. On this point the accounts of the Dutch naturalists essentially agree with those of Wallace. There is an eager search for these apes in their native place. Bock states the Malays of Samarinda, in the south-east of Borneo, capture them near the small brooks and streams which flow into the Mahakkam close to that town. These animals come down to the river-bank in the early morning and return in the course of the day to the thicket. When the natives take an orang alive, they sell him for three dollars to the Chinese, who at first feed the animal on fruit, and afterwards on rice, but are never able to keep him alive for any time in captivity.[117] Although, in the ordinary course of his existence, the orang shows himself to be melancholy, slothful, and indifferent, yet in moments of danger he becomes angry and able to defend himself. When pursued, he is said to pelt his aggressors with broken branches, and the thick, thorny outer husks of the durian fruit. This is the more probable since the Tscheladas (_Cynocephalus Gelada_), the Hamadryas (_Cynocephalus Hamadryas_), and other baboons are in the habit of hurling branches, stones, and hardened clods of earth with great adroitness at those who attack them. In a hand-to-hand fight, the orang seizes the arm of his opponent, biting and scratching it whenever he can get at it. Wallace says that no wild animal ventures to fight with these powerful creatures, and that they can even obtain the mastery over crocodiles and gigantic snakes. The name orang-utan is derived from the words orang, man, and utan (belonging to woods), and is therefore merely wood-man. It is an error to write orang-_utang_, which, according to Von Martens, signifies an _indebted_ man.[118] The Malay name, meias, is often used, and they are distinguished as meias-pappan or zino, meias-kassu, and meias-rambi. According to Rosenberg, the orang is called mawas in Sumatra, and Bock says that the Dyaks of Dusun call it këu.
