MALLETj VINDHYAN SERIES. 51 



East of Bijigurh and Chynepur the shales, if not seen in the 

 scarp, are generally indicated by fragments in the water courses, and it 

 seems that they are everywhere represented, sometimes by one thick 

 band, sometimes by several alternating with sandstone. They are not 

 found however at Sasseram or west of Chynepur, either from their dying 

 out, or sinking below the alluvium level. Should the latter be the cause, 

 it would preclude the hope expressed by Mr. Williams of limestone being 

 obtainable at Chunar at a workable depth. To the south they are trace- 

 able westwards as far as Burdhee, maldng themselves apparent by the 

 influence they exert on the contour of the scarp. It is double where 

 they exist, but becomes single after their extinction. 



Beyond this point the escarpment is much obscured by talus, and 

 sections exposing the lower portion of the Kymores are very rare. The 

 only beds yet observed referable to the lower sub-group are some about 

 10 miles west of Badanpoor, where, at the base of a little waterfall dry in 

 the cold season, some 30 feet of hard silicious ^ales occur. The beds, of 

 greenish, greyish, and reddish tints, are some finely laminated, others two 

 or three inches thick. Lithologically these bear little resemblance to 

 the Bijigurhs, but their position beneath a band of conglomerate, to all 

 appearance representing the Kymore conglomerate, which rock forms the 

 base of the upper sub-group, renders their connection with the lower most 

 probable. In the same position we must include the fine crumbling 

 yellow shales mentioned by Mr. Medhcott as occurring near the river 

 Kane in Bundelkund* and which are the only lower Kymore beds yet 

 known west of Allahabad.
