lying portion, therefore, continues the structure and strike of the 

 country as exhibited in the Sidwala sot. The fault on the north-east 

 of the outlier brings in the sand-rock again, which shows signs of 

 considerable wrenching near Khaira Chowki (54) ; but which eventually 

 settles down to a dip of 20 N. underneath the main mass of Siwalik 

 conglomerate. An inspection of the map will make this clear. 



It would seem that the line of fault along the Mitawdla sot has 

 caused this singular wrenching, whereby the outcrop of the main mass 

 of the Siwalik conglomerate takes a crescent shape. The strike of 

 the sand-rock near Ganan trig, station not having followed this 

 bending, a break became inevitable to ease the strain, and by it the 

 outlier of the Siwalik conglomerate was dropped into its present 

 position. 



The Chandi hills, or " silver hills" as their name implies, are 

 doubtless so named from the glistening appearance of the mica in the 

 sand-rock, which is in a very rapid state of decay. The material of 

 the hills is weathering in places at an enormous rate, so that the 

 surface of the slopes is constantly suffering small slips which carry 

 the soil and forest with them. It is probably on this account that the 

 forest here is so poor as to be not worth working. The cliffs opposite 

 Paili Chowki have their faces scored with deep vertical rain-furrows, 

 and streaked by innumerable depending tear drops (imitating stalac- 

 tites) of sand, which have dried in the act of running down. The 

 country shews a great area of naked cliff, so that the rocks are 

 ready dissected for geological examination. 



Mr. Medlicott has generally described the geology of the Chcindi 

 hills in his memoir ; and he draws attention to the return evinced 

 here to the normal condition of the Sub-Himalayan zone, with a 

 normal or unsymmetrical fold on the south edge, the steep limb of 

 which is south of the axis. 



I have dwelt upon the aspect of conformability between the sand- 

 rock stage and the Siwalik conglomerate, because such an impression 

 has invariably followed on every examination I have made with regard 

 to the relations of these two rock stages. It is but fair to add,
