One analysis of Barakar iron-ore by C. R. von Schwarz i shews 2"6 per 
cent. MnO. Mr. F. L. Schwenk of the Bengal Iron aiul Steel Company, 
Limited, has kindly furnished the following figures as representative of 
the iron-ores obtained round Barakar : —

The Barakar ores are obtained, of course, from the division of the 
Damudas known as the Ironstone Shales. 
Of the other ores used by this company, those from the Adjai valley, 
Santal Parganas, contain up to 3 per cent. Mn ; those railed from Kus- 
taur, Bengal-Nagpur Railway, in the Ma nb hum district, mtder 01 per 
cent. Mn ; and those from Barabhum, Bengal-Nagpur Railway, in the 
same district, 0-3 to 1-3 per cent. Mn. 
Gangpur State- 
Manganese-ore has been reported as occurring 10 miles westwards 
from Bamra station, Bengal-Nagpur Railway, in Gangpur State ; but I 
have no details of the occurrence. 
The deposit is held by Madhu Lall Doogar of Calcutta and is said 
to be of considerable size. An analysis of a large specimen from here 
by Mr. V. G. Spiera of Kamthi showed : — 
Dried at 100° C. 
Manganese . . . . , . . . . 54 37 
Silica . . . . ... . . .1-50 
Phosphorus . . . , . 0-072 
Some specimens collected from this deposit have been sent to ihe 
Geological Survey. They show good trapezohedral spessartite garnet 
and also braunite crystals, and seem to point to the extension of the 
gondite series as far as Bengal 
Hdz^ribagh District. 
In the metamorphic rocks of this district occur irregular beds of dark 
yellowish-brown massive garnet, sometimes of considerable thickness.
