consist primarily of dark reddish-brown, ferru- 

 ginous sandstone, with extremely sparse strings of iron-stained quartz 

 Lithological charac- pebbles, and occasional thin partings of dense red 

 ' clays ; there are also white loose-text«red grits, 



from which the iron has been segregated into dense ferruginous 

 plates. 



The physical characters of these rocks have been sufficiently indicated 



^, in the general sketch, and the overlap of the 



Physical characters. 



Panehets at Toobed, and the unconformable 

 superposition on the same rocks to south-east of Subano have also been 

 described. To the north-west of this hilly tract there is an outlying low 

 hill near Sasung formed of these rocks. The beds rest upon Panehets, 

 and are cut off by thefault on the south-west. The thickness is incon- 

 siderable, probably under 100 feet. 



The next area occupied by rocks of this age is situated near Juggul- 

 Area near Juggul- <^"ogra, and is about one square mile in extent. 

 ^^SS^- It is partly included between two of the main 



faults of the area, and the lowest beds are in consequence in contact with 

 the edges of beds belonging to several different groups. These relations 

 will be best understood by reference to the map. The rocks are pre- 

 cisely similar to those just described ; the thickness 

 of the beds is at present perhaps about 450 feet ; 

 they form a synclinal basin, and, as is almost invariably the case 



with the Mahadevas, they are most eflficient water

to be found in their vicinity. This I also remarked upon in refer- 

 ence to the Kamthi rocks of Hingir. 



The next area is situated to the west of the Jugguldugga hills, ex-
