The New Mysore Manganese Company has kindly supplied me with 
the figures of manganese cQutents for all the cargoes shipped since the 
beginning— 1st February 1906— of work till the 28th .June 1907. They 
represent 21 cargoes and a tonnage of 60,404 tons of manganese -ore. 
The analysts are Pattinson & Stead, J. & H. S. Pattinson, W. H. 
Pearson & Co., and E. Riley & Co. Excepting one cargo, they all 
ranged between 45'06% and 50'90% manganese. The exception was a 
cargo of over 4.000 tons, that gave 4r75% and 43'40% Mn according to 
different analysts. The calculated average of all the cargoes, making 
allowance for the different tonnages, is 47'67% Mn. The bulk analyses 
of the ores from the deposits of the Shimoga Manganese Company are 
said to range between 34% and 49% Mn according to the deposit, the 34 
figure being unusual. From the foregoing figures it will be seen that the 
characteristics of the Shimoga ores are manganese lower than in the 
Central Provinces, with a proportionately higher amount of iron, and 
very low silica and phosphorus. The Shimoga ores are in fact to 
be classed as 2nd and 3rd grade, although a small quantity of first grade 
ore might be selected. 
As regards railway communications, some of the Shimoga deposits 
are favourably situated, and some unfavourably. The favourably 
situated ones are those round Shiddarhalli, 
from which it is only about 6 miles to Masara- 
halli station, and 9 miles to Tarikere. The 
unfavourably situated ones are those round Hoshalli, at an average 
distance of 14 to 15 miles from Benkipur station ; those near Kumsi, the
