296 Silver Lead Ores of Kurnool and [No. 8, new seeies. 



has some resemblance to the argillaceous breccia, the out crop of 

 the vein at Jungumrauzpullay and places contiguous which sub- 

 stance in a state of decomposition it appeared to me ; its being 

 overlaid by the beds of sandstone which have been affected by it 

 instead of bursting through these rocks to the surface is rather 

 against the presumption of its being a mineral vein, were it not 

 that a similar example is seen near Nundiallumpett at which place 

 the vein becomes suddenly concealed by the clay slate through 

 which it has elsewere penetrated, this appears to occur at several 

 places along the line of this vein, its existence beneath the slate 

 was proved by slight excavations. 



At Buswapoor the earth is cleared out of the cavities of this 

 surface rock by the Natives and lead detached from their sides ; 

 occasionally they seem to have broken away a little of the rock 

 where two cavities have been worked near to one another, beyond 

 this their efforts have not extended. 



On the Jungumrauzpillay pass it is far otherwise ; here appear 

 to have been executed some extensive workings. 



They consist of a number of pits, many of the depth of 20 or 25 

 feet ; from the bottom of these horizontal and inclined headings 

 or galleries have been carried in various directions following the 

 indications of the mineral. 



These galleries in some cases extend 50 and 60 yards uniting one 

 or more of them ; all the excavations seem to have been effected 

 by firing the rock, a labour which in pits so close and confined 

 must have been very trying even to Natives as well as tedious and 

 costly. 



The indications of lead in these workings are very scanty, there 

 are, however, many places in the present exposed surface of the 

 rock where traces can be observed. 



The vein has the same structure at the surface as at Buswapoor, 

 and like it is similarly compounded ; these characters are also dis- 

 tinctly marked at a third place where the vein crops out on the east 

 side of the ghaut close to the village of Jungumrauzpillay, here 

 ore is seen in the rock but very minute portions.
