hydrous iron peroxide, as on laterite. The sandstone hills were seen stretching away to the 
Godavari, south of Palavaram, hut were not further examined.* 
The hills west of Pangadi' consist principally of trap, overlaid in part by sandstone or 
Traps near Pangadi. conglomerate ; underlying sandstone only appears on their 
northern edge, close to Dudukur. The fossililerous lime¬ 
stone band is distinctly intertrappean, hut at a small height above the base of the 
volcanic rocks. The trap is fine grained and compact, decomposing into the usual soft earthy 
greenish rock. All around, so far as was seen, the country is covered with black cotton 
soD, and agate fragments are scattered about as in the Nagpur country. 
To the eastward the hills are thickly capped with ferruginous grit and conglomerate, 
precisely resembling that in the Kamthis and probably derived from their waste. This rock 
is well seen near Daicharla and south of the bungalow at Pangadi. In the latter place it 
consists of coarse white speckled felspathic sandstone yellowish-brown in colour with ferru¬ 
ginous hands. The trap can be of but little thickness, probably not more than 200 to 250 
feet. It is seen on the road from Pangadi to Bajamahendri and reappears north of the 
latter town, whilst the overlying sandstone appears to form the hills at Dowlaishwaram.
