These beds^ although well exposed^ present a broken section^ and 

 cannot be measured with accuracy. 



Koughly estimated^ they probably do not exceed 600 feet. The boulder 

 conglomerate^ besides being seen in the Sooknid, is met with along the 

 extreme western boundary, north of Mukpitto, and again, in the Khakho 

 Nuddi, near Pipratand. 



Although the bottom bed of the series, the boulder conglomerate, 



as I have already shown, does not crop out con-

tmuously along the natural boundaries, but is over- 

 lapped and hidden by the higher shales and sandstones. Its thickness 

 is never very great : within the limit of my own experience I know of 

 only one instance in the Jherria, and another in the Karuiipura fields, 

 where the local accumulation of boulders and detrital matter, exceeds 

 30 feet. 



The shales are largely made up of that peculiar variety .(which

needle-shale, and which forms in every area where Talehirs are developed 

 the ' stamp rock^ of the series. On the high land of Jurbiidih and 

 Bukhshidih these shales dipping at angles of 5° and 20° rest directly 

 on the gneiss at the boundary, and conceal the boulder conglomerate. 

 They are excellently seen in the Sooknid, and, sweeping round, constitute 

 the main body of the series between Dhobidih, Mukpitto and Pipratand. 

 They are exposed in the Khakho, dipping at an angle of about 10° to 

 the east. 



The sandstones, although alternating with the shales, form an horizon 



above them, marking the upper part of the series.

They are, as a rule, fine-grained, and might be 



easily worked and turned to good account.
