CHAP. 4.] KARNÜL FORMATION.—BANAGANPILLY GROUP. 105 
among the people. We were only guided by the extraordinary 
resemblance between these beds and what are in other places strata of 
the diamond group; after all, of course, a very weak argument in trying 
to make out relations amongst the numerous bands of, quartzite in our 
whole series of KADAPAH- and KARNUL rocks. 
The Ramulkota mines, nearly 20 miles south-south-west of 
mn Kurnool, included both rock workings and alluvial 
washings. They are now merely alluvial wash- 
ings, the material for examination being dug from the edge of the 
alluvial plain which runs close up tothe southern end of the village. 
In old times, however, the quartzites around the village were quarried, 
the rocky surface of the rising grounds to the west and along the northern 
base of the neighbouring Gunnygull ridge to the east-south-east being 
covered with ruins of pits and heaps of the broken rock. The Banagan- 
pill; group, as will be seen on the map, has been left here free from 
denudation and faulting to some extent. 
Before concluding this chapter, it may be useful to give a list of 
all the known localities of old and modern diamond 
Other localities. C 
workings in the country under description. 
There are one or two which we have never been able to find out, the 
names of the villages as given by the writers on the subject not being 
now known. There are likewise some names common to several villages ; 
but we have taken for granted that they are sites of the same name 
which are either on Banaganpilly strata or adjacent. Three of the 
localities are rather far from any outcrop of the quartzite in question, 
are deserted now and gone out of remembrance; and they can only 
have been alluvial washings, if they ever were diamond producing places. 
The late Captain J. G. Russel, when Assistant Commissioner at Kurnool, 
made some very interesting collections of supposed and true diamond
