DETAILED DESCRIPTIONS.

From Dliaree to Bukkutgurh, the beds undulate, no great thick- 

 ness being exposed, but a considerable change in colour takes place. 

 The rocks pass down from red quartzite-sandstones into grey quart- 

 zite beds, often shaley and flaggy and having frequently a very 

 compact appearance. These beds are often coarse and conglomeritic 

 and contain jasper pebbles. In places they have a peculiarly trappean 

 aspect, as if made up of trap detritus, and they vsreather into con- 

 cretionary masses. Below Bukkutgurh the dip is 10° to 15° to the 

 north of east. The trappean-looking beds con- 

 tinue, associated with quartzose and conglomeritic 

 bands, containing pebbles of jasper, red quartzite, and black chert. 

 Markings like annelid tracks occur on the rippled surfaces of the 

 beds. Some oblique lamination is seen.

Below Mandata (Oonkarjee Maharaj), which island consists of 

 these rocks, the typical quartzite-sandstones recur, 

 and form the base of the beds near Burwai; 

 they are massive purplish beds similar to those seen near Chandgurh,
