part of the island {Table Peak), north of Klong Sarlakpet, and 

 rises nearly to 2450 feet. 



The hills of Koh Chang consist of a rather small-grained 

 eruptive rock, most commonly light-brown or red in colour, 

 more seldom greenish. 



A narrow strip of plain surrounds the hills of Koh Chang; 

 its soil is a very compact, reddish clay the presence of which 

 is due to the denudation of the hills. 



Whereas no lakes or ponds of any importance are found 

 in Koh Chang, a great number of small rivers and rivulets in- 

 tersect the island taking their rise from the hills in the interior. Their 

 water usually streams very quickly and they are often broken by 

 waterfalls. Most commonly these waterfalls are small; some more 

 important ones are found near the east-coast in Klong Munsê and 

 a little more southward in Klong Majum, near the west -coast in 

 Klong Prao. In the dry season the rivers contain but little water; 

 but during the south-west monsoon they swell and fill up their 

 stony beds. When the rivers have reached the plains near the 

 coast, their course becomes more quiet, their breadth increases 

 and some of them are navigable for small crafts for some distance 

 from the sea (Klong Prao, Klong Sarlakpet, the latter debouching 

 in the great bay at the south-end of the island). 



Especially in the more exposed west -coast of Koh Chang the 

 steep rocks go right down to the sea, but in most other places 

 the shores are low and flat, their soil consisting of coral-sand 1 ) 

 or stony gravel. Where rivers debouch and assume the propor- 

 tions of more important estuaries , the ground is covered with a 

 black mud and occupied by a luxuriant mangrove- vegetation. 



The hills of Koh Chang are all covered with the densest 

 jungle from the feet to their highest top. As the vegetation on 

 the whole, this jungle has been but little influenced by the scarce 

 Siamese and Chinese population scattered along the coasts, where 

 Hongs debouch. 



Villages of some importance are situated at the mouths of 

 Klong Munsê (east-coast) and Klong Sarlakpet (south-end) ; besides 

 which some few people live at Klong Son (north-end), Klong Prao 

 (west-coast), Ao Savan (south-end) and a few other places. 



') The sand here is often much more large-grained than on our northern 

 shores consisting of hig coral-fragments. In some places however common 

 quartzy small-grained sand can be found.
