range. It is here we first come upon the strike of the underlying forma- 

 tions, but for the reason given — the variableness of the section, — I shall 

 not take them up here and follow them out to their extinction beyond 

 the Dessaun. Here at starting I may notice a contrast with the Vin- 

 dhyan formation in which the sameness of section over a very large 

 area is remarkable. 



The portion near the Jumna, although showing on the map the 

 greatest expanse of the Semri formation, is the least determinate of all ; 

 indeed the Tirhowan limestone is the only recognizable group of the 

 series, and it occupies but a small part of the area; the rest has been 

 coloured as the same group, for reasons that will be pointed out. 



In the valley of the Boghin is the first appearance

we have, at the village of Siha, sharply jointed dark blue slaty shale rest- 

 ing horizontally on blue limestone, the Semri shale and limestone : the 

 group is met with in all the valleys to the west, becomes fully exposed 

 in the valley of the Semri and perhaps more typically in the shallower or 

 more elevated valleys (not expressed on the map) near Sobha and Kyra. 

 Between this and the Chokeydar river near Hinota they exhibit some 

 change in condition, being again at their former low level ; and at the en- 

 trance to the gorge of the river under Sanodo they are seen for the last time.

 comes very largely developed, forming the sloping bank of Pundoah 

 hill. It also diminishes suddenly in importance at about the same 

 place as its overlying group ; but is unmistakeably recognizable as 

 far as the Dessaun. 



The Dulchipore sandstone first shows itself at Chopra — but does not 

 attain much importance till about the place where the two lower groups 

 have been said to decline: in that river under Sanodo it is already very
