No. 1 was a specimen of pyrolusite, mixed with some of the grey 
crystalline mineral, and some wad. 
No. 2 was a piece of light grey crystalline ore mixed with a little 
psilomelane. An analysis of a purer piece of this crystalline mineral is 
given on page 78 ; and judging from this analysis I suppose that the 
mineral is probably polianite. If it be, then the specimen of which 
the analysis is given here is simply a more impure piece. No. 3 is 
an analysis of a sample of 933 tons of ore stacked on the mine in 
August 1907. The phosphorus in Nos. 1 and 2 was not determined, and

the deposit. 
Besides the ore in situ there is a considerable quantity of detrital 
ore exposed in quarries on the slopes. I am told that the best 
portions of these detrital deposits lie on the N. and N. W. slopes of the 
hill.

in the. hills south of Aladhalli village.

the Shankargudda Eange after this peak. Shankargudda peak is
