MALLET, VINDHYAN SERIES, 15 



into the long winding gorges which convey it to the alluvial plains of the 

 Ganges. But as we proceed westward, the general level sinks, and the 

 hills become less prominent, until west of Shahgunj, the Tonse and its 

 tributaries flow through plains of alluvium in which rock is seldom seen. 

 The northern scarps at the same time of Mirzapur and Allahabad become 

 much reduced in elevation, and the southern, instead of forming merely 

 the edge of a plateau, becomes a ridge with a slope, although less steep still 

 almost as great, on the north side as on the south. The Sone valley at 

 Burdhee and the Kymore country to the north are of nearly equal eleva- 

 tion. Westward of Allahabad the Kymore plateau is reduced to a narrow 

 strip of country between two escarpments, of which the northern, or Ky- 

 more, acquires in Bundelkund the elevation which it had lost in the 

 Allahabad region. Thus it will be seen that the most elevated and 

 the wildest part of the Kymore plateau is its eastern extremity, a 

 fact which is also true of the Rewah and Bundair plateaux, the differ- 

 ence, however, being less marked in the Bewah than in either of the 

 others. 



The general level of the Rewah table-land is tolerably uniform. The 



country is rocky and barren where the sandstone oc-

cupies the surface, but farther from the edge, where 



the lower Bundairs appear, it becomes fertile and thickly inhabited. Much 

 of this ground indeed is covered by alluvium. The southern boundary is 

 the Kymore ridge, which slopes down to the north so much that south of 

 Rewah the surface is only 100 feet higher than the Sone valley. West 

 of Rewah the range becomes double, the intermediate valley being, in 

 fact, the continuation of the Kymore plateau. The eastern and northern 

 edges of the Rewah plateau are marked by another fine escarpment, over 

 whose edge the drainage falls in a series of waterfalls of great beauty, 

 varying in depth from 200 to 400 feet. In Rewah the southerly inclina- 

 tion from the edge of this escarpment is very slight, but it increases as
