KHASI HILLS.

at the top of the hills, 

 nearly at the level of the 

 plains close to Laour, 



Apparently n , 



a general an- ^""^ ^° 

 ticlinal near „„„j„j.t,„ 



Cherra. wards the 



West (as noticed by 

 several observers), is in 

 some degree a confir- 

 mation of this state- 

 ment. The same fact 

 appears to hold with re- 

 ference to the sand- 

 stone group towards 

 the East also, for we 

 find beds of the same 

 nummulitic limestone, 

 coal, and sandstone, 

 with the same group 

 of beds below them, 

 forming the hills near 

 Lakadong ; but there 

 attaining only an ele- 

 vation of not more 

 than 2,500 feet, while 

 at Cherra they reach 

 4,500 feet(a). 



(a) The thin outlying caps 

 of sandstone at Joowai are, 

 in this part of the hills, ana- 

 logous to the outliers of 

 Nungbri and Laidom, North 

 of Cherra Poonjee.
