MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [pART IV : 
the point where the above-mentioned road crosses to a point Uttle 
to the east of hill A 2,213. The analysis carried out at the Imperial 
Institute shows :— 
Sample No. 62. 
Manganese peroxide . . . . . . ,53-02 
Manganeste protoxide . . . . . 23 '48 
Ferric o.xide . . . . . . . 10-68 
Silica (combined) ....... 4-11 
Silica (free) 1-44 
Pho.'iphoric oxide ....... 0"29 
Moisture at 100°C 0-30

and indicates a mixture of 41% of braunite with 57% of psilomelane, 
the remainder being quartz, etc. Much of the manganese-ore contains 
little films of quartz, which it would be very difficult to clean out except 
with a very great waste of otherwise good-quality ore. 
An interesting feature about this deposit is the fact that the phos- 
phorus increases in amount on passing from the Samnapur to the Ukua 
end of the deposit. Analyses by Dr. Schulten, kindly supplied by Messrs. 
Burn & Co., showed the following phosphorus contents : — 
Samnapur ....... 0'06 
Ukua 0'16 
Gudma 0-20 
Nearly the whole length of the deposit (except at the extreme north- 
The working of the east end) contains ore of quality equal to that shewn 
'^'^P"'*''-' by the above analyses, and in many places probably at 
least half the thickness of the band will be found to be composed of mer- 
chantable ore. Hence there is no doubt of the existence of large quan- 
tities of a fairly high-grade ore (albeit somewhat high in phosphorus). 
It will be, moreover, fairly easy to quarry, for the overlying rock is an 
easily-removed mica-schist, and the dip is fairly small. The only 
obstacle then is the question of transport. The parts of the deposit 
that would probably be worked first, namely from Ukua westwards, 
are situated about 25 to 20 miles by a fairly good road from Balaghat 
Railway Station, Bengal-Nagpur Railway. The crossing over the Uskal
