quartzite bed (Wo. 3) which stretches across the Chintapilly peninsula 
from Jatapalle to opposite the Vadadry hill pagoda; from its superior 
hardness it has remained as a capping to a ridge a couple of hundred 
feet high. This is generally a compact whitish quartzite often much 
permeated by quartz veins. The rock is often of remarkably waxy lustre, 
and then extremely hard and slippery. This formation is again followed 
by slates of grey or chocolate colors (7), overlaid in their turn by a 
bed (No. 4), which in some parts is decided grit, in others again a true 
quartzite, the passage between the two being rapid. Where the gritty 
character obtains the whole surface of the bed is riddled with old 
diamond-pits. Occasionally the grit passes into a regular pudding-stone 
of white or grey quartz pebbles included in a silicious matrix. Over 
some parts of its surface this bed has been much denuded so as to form 
a mere film often only a few inches thick. This is the case where 
erossed by the line of section. It is here also of very small thickness, 
but thickens out again both to the east and west, to a formation of 
considerable importance. 
This diamond bed may be traced right across the Kistnah on either 
side of the peninsula) It is overlaid by a series of chocolate-colored 
or mottled slates (e) of no great interest or importance; these in their 
turn are covered by a thin bed (No. 5), waxy and quartzitic in texture, 
which, like bed (No. 4), has in places been worked for diamonds. 
This bed appears again a little to the south, being brought up to the 
surface by a fault. 
Resting on bed (Wo. 5) comes another series of slates (f) of 
mottled chocolate and white, pale chocolate, or drab colors, capped 
by a quartzite and diamond-grit formation (Wo. 6), forming a long 
narrow plateau about a mile west of the village of Ballagarige. 
This plateau appears to form the upper bed of a very flat synclinal 
fold, so flat as to be barely appreciable in the uppermost beds. 
The lowest bed of this band is a grey or whitish quartz-veined
