trap topped hill east of the station, and appear at the little hill on which 

 the Jogi's hut is built. Many fossiliferous beds have been detected in this 

 neighbourhood, and the plants are the same as those of the Maha- 

 nuddi shales ; here however no rocks belonging to the lower Da- 

 muda group are exposed, and the shales and sandstones which repre- 

 sent the upper division rest on, and are faulted against, the crystalline 

 rocks. 



From the Mahanuddi all along to Jubbulpore, a narrow strip of these

and the Mahanuddi. j n seve ral localities ; but the Lameta beds (and 



over them the trap) overlapping these on the south, leave but a very 



small area of them exposed between themselves and the faulted North 



boundary of the upper Damudas. Passing from Jubbulpore south west 



down the Nerbudda valley, these rocks are pretty continuously seen along 



its south side, as far as the meridian of Nursingpore, and I shall now proceed 



to describe a section found in the Sher river, 12 or 14 miles east of this 



latter station. 



Close to the village of Sehora (see map) the crystalline limestone of 



the schist series is found to be brought by a fault 

 Sehora section. 



into contact with — 



An earthy green and brown sandstone, pebbly and sometimes suffi- 

 ciently so to be a conglomerate. 



This is the lowest bed seen of the upper Damuda group here. Ascend- 

 ing the stream, and ascending also in geological succession, we find resting 

 on the above, — 



An earthy friable sandstone, with carbonaceous markings and some 



irregular carbonaceous partings ; 

 A brown sandy shale (laminated) with regular carbonaceous layers, 

 and a band of coal 6 inches thick where best seen, but thinning 

 out to 4 inches within a few feet along its outcrop ; 

 Over this, a band of fine grained brown sandstone ;
