16 MALLET, VINDHYAN SERIES. 



we proceed west, so that past Nagode we find ourselves in a broad valley 



bounded on one hand by the Bundair scarp, and on the other by the 



slope of the Punna ridge, until beyond Dumoh we arrive at the trap- 



pean hills of Central India. 



The part of the Bundair plateau east of the river Kane is the most 



elevated, being separated from the E-ewah by a line 

 Bundair plateau. 



of escarpment 500 to • 800 feet high. The usual 



character of the country is that of low rolling jungle-covered hiUs ; the 

 streams which flow between them being bordered by a narrow strip 

 of alluvium, on which the villages are situate, and where only there is 

 any attempt at cultivation. The tract west of the Kane maintains very 

 much the same character of rock and jungle, but it is on the whole lower. 

 Much of it, indeed, is but sHghtly higher than the Rewah plateau to the' 

 north, for although the escarpment presents a northern face some hundred 

 feet high, the surface slopes rapidly from the edge in a southerly direction. 

 In general contour, however, the Bundair tract is more irregular than 

 either of the others, some parts, like that west of Belhari, forming small 

 isolated table-lands by themselves. Between Saenugm-h and Rypora 

 the usual jungles are replaced in part by grass-covered rolling plains. 



The Sone valley south of the Kymore escarpment is occupied by 

 numerous ranges of hiUs, which never exceed a few 

 hundred feet in. height, and preserve a general par- 

 allelism to each other and to the Kymores for long distances. This con- 

 figuration is owing to the diversity in the strata of the lower Vindhyans 

 and older formations, and the disturbances by which they have been 

 thrown up at various angles while preserving a uniform strike. As usual 

 under these conditions, the softer beds have been cut out into long nar- 

 row valleys between the ribs and hills which mark the harder beds. 

 These features are better developed amongst the schistose rocks than 

 amongst the lower Vindhyans from greater disturbance and contrasts of
