MALLET, VINDHYAN SERIES. 55 



worthy of mention that the lower Vindhyans which can be easily 



recognized by their lithology and which become finally extinct near 



Kuttung-ee, also become finally extinct north of Sagar, while the 



Kymores are continuous up to Gwalior ; that difference between them on 



the north favours the idea of a similar difference to the south; and 



taking the very constant applicabihty of the threefold division to the 



upper Vindhyans elsewhere, as along the whole northern and western 



boundary down to Neemuch, into consideration, the likelihood would seem 



to be that the Kymores are represented in the Nerbudda Valley and that 



such are the lower strata of those vast accumulations of sandstone by 



Hoshungabad and the Dhar Forest."^ 



About 10 miles west of Badanpur between the shales mentioned 



above (page 51) and the sandstone, 4 or 5 feet of 

 Kymore conglomerate. 



conglomerate occurs, composed of ferruginous, al- 

 most hsematitic pebbles, the largest about four inches diameter, and others 

 of quartz. The former are far the more abundant ; the remainder of the 

 rock being of finer ferruginous materials. This is the only recorded ob- 

 servation of the Kymore conglomerate on the southern edge of the Vin- 

 dhyans. It is very rarely that one obtains a view of the base of the Ky- 

 mores along the upper Sone Valley, but to the east where some sections are 

 procurable, the rock is certainly unrepresented. It is however largely 

 though unequally developed in Bundelkundf where it behaves Kke a shore 

 deposit in attaining its greatest thickness at the edge of the escarpment 

 and thinning out to the south, as seen in river gorges. In this respect it 

 resembles the base conglomerate of the lower Vindhyans in the Sone 

 Valley, and both are supposed to be littoral beds approximately markino- 

 the original limits of deposition. On Pulkoa HillJ, near the river Kane, 

 the rock is composed of well rounded pebbles, mostly from J to 1 and \\ 

 inches diameter, the largest seldom exceeding 3 : the vast majority are of 

 bright red jasper ; the remainder of dark purphsh jasper ; a smaller num-
