166 KING: KADAPAH AND KARNÜL FORMATIONS. [PART III: 
There are, again, further traces of serpentinous limestone in Mulkapoor 
terrace, north of the Puspulla valley, where the strata are between sheets 
of trap: and those beds which are in close contact with trap, either above 
or below, are impregnated with serpentine 1n strings and segregations.. 
Further north still, between Moodwaram and Yenkatgerry, the 
shales of this series are very magnesian, some of 
Steatite or * Bulpum. 
the layers being nothing else but fine grey and 
greenish steatite. There are also seams of the finer form, or < French 
Chalk, which is here called, and known over South India, as 
> Bulpum.* This is the quarrying place for steatite in the district. 
The next marked locality of serpentinous limestone is close to Kurnool 
Serpentinous limestone ON the east side of the suburb of Torapore. Here, 
Teon K nopi easy rolling beds of pale green and white lami- 
narly-waved limestone occur underneath the great spread of trap further 
eastward ; and similarly altered beds show again nearer to Kadrabad, 
lying on the same sheet of greenstone. Generally, these beds are very 
pale green or yellowish ; but there are occasional cases of darker green 
strata, with laminz arranged im frequent convolutions, which would 
give a finely clouded marble. 
The same limestones and associated silicious beds, with what 
appears to be an extension of the same trap flow, 
Vaimpullys overlap 
theGooleheroosonthe show at intervals along the banks of the Toon- 
hae gabudra, below Kurnool, up to the entrance of the 
Kistnah into the Nullamullays. Inside the Kistnah gorge there are 
frequent traces of serpentinous bands and steatitic layers, associated with 
trap: and here the series is lying directly on the gneiss without any 
intervening sands or gravels of the next lower division of the sub-group. 
* This ‘Bulpum’ is largely used by the people as a chalk for writing on their 
blackened boards, or small folding books of blackened paper, or canvas. The associated 
bands of steatite and steatitic shale, which are of various shades of brown, green, and 
purple, are carved at Kurnool into paper weights, &c.; some of which are very well cut, 
and extremely quaint in their designs. The semi-translucent character of the yellow and 
green colored rock makes it admirably suited for quaint carviugs of groups of crabs, 
seorpions, or frogs, which are the favorite subjects of the artists.
