MALLET, VINDHYAN SERIES. 6^ 



was a foot or so of hard thin flagg-y sandstone, and about seven feet of the 

 same mixed with shale. A little further to the south and west on this 

 terrace was an old pit between 30 and 40 feet deep, but the bottom filled 

 with water, so that the rocks immediately above the diamond bed could 

 not be seen, but there were certainly 10 to 15 feet of shale between.it and 

 the lower Rewah sandstone. In all the pits examined there must have 

 been 10 to 20 feet of shale intermediate. The Punnas are here very 

 thin, so that this position is not much above the top of the Kymores; 

 . There are some small outlying hills to the north at the village of 

 Bungla and north of Babupur. The former is about 50 feet high^ 

 with Kymores at the. base, then 15 to 20 feet of shale, capped in 

 turn by the lower Rewah sandstone : this was the only outlying hill 

 in which the shales were seen (on account of the northern overlap) . 

 A few hundred yards to the north-east, another little hill has been 

 excavated in every direction by the old diamond searchers. Again at 

 Babupur are numerous old pits and some sufficiently well preserved 

 to admit of examination. They are about 15 feet deep exposing 

 sandstone with thin flaggy beds at top, but no shales. 



A bed of fine brown sandstone, including fragments of a green 

 silicious rock and bits of red and green shale, was traced from 

 Bumbhea to near Kissengurh, which is not impossibly the continuation 

 of the diamond bed ; that the natives do not work to the east is no 

 proof that the beds do not continue in that direction. This is evi- 

 dent from the fact of there being no pits at Bimgla, notwithstanding 

 the hills all round', even to the north, having been extensively worked'. 

 It is therefore almost certain that at Bungla the diamond bed" exists, 

 yet is untouched.* 



The lower Rewah sandstone is in places nearly 100 feet thick, ia 

 massive beds of 3^ and 4 feet, fine textured, white and pinkish in color;
