This indicates the presence of some 11% of braunite and is equivalent

In the only year, namely, 1899, for which I have been able to obtain 
the output figures of Devada separated from those of Kodur, the 
output was 2,167 tons, 
Mr. Caplen sends me the following figures shewing the range of 
analysis of Devada ores, which, however, are no longer (in 1906) being 
extracted : — 
Manganese 42-5 to 50-0 
Iron 3-5 to 11-0 
Silica 1-5 to 4-5

The succession of shallow pits lying within the limits of this village 
^ , forms the southern end of the manganiferous 
Detrital accumulations. . i i 
belt, as far as it has been traced. Most or the 
pits disclose only detrital accumulations of pebbles and boulders of 
manganese-ore and khondalite, in a matrix composed of pisolitic granules 
of manganese-ore, hematite, limonite and quartz, set in a red clay. In 
one of these excavations, situated at the 
Amethystine quartz. j f a j j ^ 
nortnern end or bandanandapuram, at a point 
a little to the N.E. of the north end of khondalite range of hills lying to 
the west of the Sandanandapuram quarries, a considerable quantity of 
loose pieces and crystals of quartz was being removed. Some of these 
were water-clear, free from flaws, and often pale rose or amethystine 
in colour. One piece showing pyramidal and prismatic faces is 9 inches 
across. Another doubly terminated crystal is smoky quartz. In the 
most southern pit (known as the Dimidi pit)

the detrital accumulations rest on brown chert, 
which here occurs in considerable quantity and is veined and patched 
with psilomelane. In an ore stack here the ore was traversed by a 
network of cavities lined with chalcedony, some of which was pale 
rose-coloured, the ore being both psilomelane and pyrolusite.
