8, — Section in the Si la Chua Nullah. 

 Nearly the same succession of rocks, crushed and tumbled together in 

 the most perplexing manner, is met with in the dry nullah of Sita Chua, 

 running into the Banki nullah east of Dhamni. North of the former 

 village I met metamorphic rock (mica schist and quartz schist). In 

 the nullah near the village I met a white mealy soft sandstone, not 

 unlike what I saw in the former section (No. 301 H. T. is composed of it) ; 

 here and there it is mottled with reddish beds, but otherwise it resembles 

 the Mahadevas. It is hollowed out in large pot-holes, one of which is 

 worshipped as Sita Chua (the rise of Sita) . In the many windings of 

 this rivulet, only here and there rocks appear in situ, the rest are hidden 

 by sands and rubbish. In the bed of the Banki nullah near the junction 

 with the Sita Chua nullah Raniganj clay shales are exposed, and a 

 little further west in the bend of this river trap is in situ, and forms a 

 dyke across it; I traced this dyke for miles in a nearly east- west 

 direction towards Nowadih. The rocks, however, right and left of the 

 Banki nullah, are so much denuded and the whole country levelled down 

 to the river banks, that no exposure is seen for miles round until we get 

 to Dhamni, where red clays are seen, overlaid further on by Mahadeva 

 sandstone. These red clays occupy invariably the place just below. the 

 Mahadevas, and most probably represent Panchets. This section, and
