and regular increase of elevation to 2,477 feet in the neighbourhood 



of Sunhat, the capital of the Korea State on 82° 25' E. Long. The 



loftier peaks, such as Bandogarh, Koreagarh, Mahora, and the crests 



of the Dakhan uplands, of which Amarkantak is one, are respectively 



2,662 feet, 2,955 feet, 3,371 feet, and 3,400 feet high. 



The hills vary in shape according to the rocks of which they are 



made up. Those of Bandogarh and its associates

are usually flat topped with precipitous sides for 



some distance down, and then a sloping termination of broken rocks and 



stones to the foot, preserving a steady alignment for long distances or 



sweeping in full curves. This is the characteristic form produced by the 



sculpturing of the Mahadeva and other supra-Barakar sandstones, and 



is quite distinct from the scarped facing of the trappean plateau, which is 



much more irregularly eaten into, and has not the same prominent 



accumulation of debris at its base. 



The small independent hills, of trap, sandstone, or shale, have no 

 definite contour, and are narrow or broad, conical or lumpy, as the caprice 

 of Nature has determined. 



The highlands to which reference has just been made constitute the 

 watershed of several of the larger rivers of India. 



Rivers 



Of these, the Son more immediately concerns 

 us ; as, though the Narbada rises in the Amarkantak plateau, a part 

 of Rewah, it soon passes into the territory of the Central Provinces, and 

 beyond the scope of our notice. 



The Son has its source in the Pendra table-land at an elevation of 

 2,100 feet, but it enters the Rewah State about 30 

 River S6n. miles from its origin, and a short distance above 



its junction with the Kewai. Thence it flows in a generally northern 

 direction, until it receives the Mahanadi. At this point, in 24° 5' N. 

 Lat., and 81° 5' E. Long., it is diverted to the east, and holds that way 

 until it falls into the Ganges. 



Its feeders in its upper course are quite equal to it in size, and in 

 fact the Kewai, which has its origin in the uplands of Korea, is a more 

 - important stream, and contains a greater volume of water.
