BUNDELCUND. 29 



of the Kymores. All that I care to insist upon is, that prior to the 

 Semri formation, this great bank of crystalline rocks existed, and that, if 

 not strictly a coast line, it influenced most markedly the accumulation 

 of these same rocks. In the two upper Semri groups this original limi- 

 tation is more marked ; they are almost invariably strictly horizontal 

 even when within a short distance of the sloping boundary surface : and 

 also there is no doubt about their irregular denudation preparatory to 

 the Vindhyan period. It appears even necessary to assert that the 

 Pulkoa schists were subjected to irregular denudation before the form- 

 ation of the Tirhowan limestone. 



The behaviour of this schist or shale, is of the same kind as that of the 



limestone — about Dowara it is in great force, it

shows as rounded hills flanking the table land scarp; 



along the Dessaun it does not appear, and again beyond, at Bundo (a 



deserted village) it is typical, with the red conglomerate resting on it. 



This section of the Dessaun is about the least typical to be found, indeed 



from it alone one would hardly surmise a distinc-

tion between the Semri and Vindhyan formation. 



The Bijawurs reach up to Koorut. On the east a low but decided out- 

 crop, 10 feet high, of Semri sandstone comes nearly up to the river ; here 

 it does not show, and on the other bank and under Koorut the thick peb- 

 bly Dulchipore sandstone is within a few feet of Bijawur greenstone. 

 This coarse, massive sandstone continues up the river for some miles with 

 scarcely any inclination in it, about Kairwa the more flaggy beds come 

 in. On the high point over Kairwa, the Kymore sandstone is easily re- 

 cognized, and about 100 to 150 feet from top the beds contain many 

 pebbles, principally of red jasper, but below them are pure sandstones; this 

 pebbly band I take to be the true representative of the Kymore conglome- 

 rate : when the section is so far cut back, away from lower line of junc- 

 tion, the conglomerate becomes broken up and lost, showing that it is not 

 strictly a bottom-rock of the Vindhyans, but only so along this obstructing
