are densely clothed with jungle and have fringing reefs of coral. 

 I have visited three or four of these islands, and they ai-e all of the 

 same character. 



On the main land there is a cluster of hills called the false 

 Bindings, from the fact, that at a short distance they look like 

 islands. They give rise to small rivers such the Bindings River 

 and its tributaries. This cluster is also granitic, and tin occurs on 

 the alluvial beds derived from it. 



GUNONG BUBU. 



North-east of this group, but quite detached from it, is a series of 

 parallel mountain ridges with a uniform N.N.E. trend. These 

 ridges are eight or nine in number. The central one is the highest, 

 culminating in Mount Bubu, a fine peak of about 5600 feet in 

 elevation. All the ridges are granitic with occasional patches of 

 metamorphic schists, all more or less rich in tin, though there are 

 but few mines in this group. A remarkable character in these 

 mountains is that all the ridges are extremely steep and frequently 

 interrupted by granite precipices of 1000 feet or more. Gunong 

 Bubu is only accessible in one or two places, the summit being 

 surrounded by escarpments of rocks of great height. 



Rivers Kangsa and Kenas. 



Many small streams join the Perak River from this range. The 

 Rivers Kenas and Kangsa both flow into the Perak from the slopes 

 of this group, the Kenas in a south-east and the Kangsa in a north- 

 east direction. In an ascent made by me to the summit of Mount 

 Bubu, I was able to explore some of the sources of these rivers, 

 which aflbrd a home to many a Rhinoceros, but few other animals 

 except monkeys (Hylobates, Semnopithecus and Macacus.) The 

 rivers descend many hundred feet in a series of cascades, giving 

 rise to some of the finest scenery in the Malay Peninsula. 



Gapis Pass. 



North of Mount Bubu this group of ridges falls away abruptly, 

 leaving a narrow pass (Gapis Pass) between them and the west
