MAMMALIA 



found in Borneo and Sumatra, lives in tree tops, but comes to the 

 ground for water. It is easily tamed when young, but as it ap- 

 proaches maturity becomes savage. It is about two-thirds the size 

 of a gorilla, reaching a height of four and one-half feet. It sleeps 

 in a nest of broken branches in the fork of a tree. 



The gorillas are the largest and most powerful of the monkeys. 

 They have a tremendous barrel-like chest and massive frame and 

 are able to aquit themselves with distinction in any battle. Since

the time of Du Chaillu, gorillas have been regarded as most ferocious 

 beasts. The late Carl Akeley believed however that the gorillas of 

 Western Africa rarely attack man unless forced to a fight. Gorillas 

 reach a height of six feet and weigh as much as five hundred pounds. 

 The chimpanzee (Figure 234) is a third smaller than the gorilla and 

 has a large brain and the keenest mind of any ape. It is easily taught 

 and when young is quite popular with directors of animal films. 

 The two species of chimpanzees are natives of equatorial Africa.
