form an area lying between the manganese areas of the Chhindwdra 
district and western Balaghat. This area might well be examined 
with considerable prospects of success. If any deposits be located 
in this area it will in some cases probably be foimd cheaper to 
transport the ores north to the Chhindwara-Seoni portion of the Satpura 
Railway rather than to carry them south to the main line of the Bengal 
Nagpur Railway. 
In Jhabua prospecting for further occurrences of the gondite series 
should be directed to the extension towards the north and north -north- 
west of the Aravalli rocks occurring in the Rambhapur area. Some 
unimportant deposits of manganese-ore have already been discovered on 
this line of strike. It will be seen from the geological map of India that the 
Aravallis of this area are probably continuous with the main outcrops 
of this system inRajputana. Hence prospecting in the portions of Raj- 
putana lying to the north of Jhabua, as, for example, in the State of 
Banswara, might have some prospects of success. Indeed, I am told that 
manganese-ore of inferior quality has already been found in Banswara. 
A more extended examination of the metamorphic and crystalhne area 
of Narukot and the adjoining portions of the Rewa Kantha area 
might reveal the presence of manganese-ores. Similarly all the areas of 
Dharwar, Aravalli, Champaner, or Chilpi, rocks in India might yield, 
on careful prospecting, further deposits of manganese-ore, as also any 
portions of the metamorphic and crystalline complex that are suspected 
to contain rocks of Dharwar age folded in with the older rocks.
