 (Plate 4) . Their southern boundary is a fault, evidently of considerable size, 

 immediately south of which trap re-appears throughout. In one place meta- 

 morphics occur north of the principal fault, but apparently themselves separ-

 These sandstones are first met with to the eastward close to the 



extremity of Sheet 54 and of the present map.* 

 Near Mankapoor, &c. ^ 



A narrow strip of beds, much tilted up and 



indeed nearly vertical, only 50 to 100 yards in breadth, occurs for a mile 



along the fault, north-east of Mankapoor. They are then not seen 



for a short distance, but come in again about half a mile east of Koom- 



durra, and are here somewhat broader and less distm-bed. After about a 



mile they are again cut out, but re-appear after a short interval just 



east of ThuUotee, and thence extend for several miles to the westward. 



A fair section of these sedimentary beds is seen near Dhabka^ in 

 a stream running, past that village and ThuUotee. 



The topmost bed is the usual calcareous sandstone with cherty 



blocks, so tyj)ical both of the Lameta and Bagh

felspathic sandstone. Each of these beds is between 4 and 5 feet thick. 



The next bed in descending order is an impure earthy, rather gritty 



sandstone, greenish in colour, abounding in irregular lumps and nodules

 more exposures occur in that direction,
