deposit having been originally discovered frc m the projection at the sur- 
face of a very small mass of manganese-ore. Most of these deposits seem 
in fact to be the summits oi small hills buried in the alluvium, and, owing 
to the fact that they all lie on the same line of strike, it does not seem im- 
probable that they really form one continuous band of rock, the interme- 
diate portions of which are buried beneath the alluvium, so that they 
correspond to one original layer of manganiferous sediments. Before this 
portion of the country was covered up by alluvium this supposed 
continuous band probably cropped out continuously over the whole 
length of 12 miles and was eroded by the usual agencies into a line of 
small hills or hillocks. I have often noticed that in a manganese-ore 
deposit where there is also manganese-silicate-rock, the manganese-ore 
stands up relatively to the silicate-rock as if it withstood weathering 
better than the latter. Assuming this to be the case and that the 
manganiferous band was irregularly altered mto manganese-ore, it 
seems probable that in the 'ine of hillocks postulated above, the 
highest peaks correspond usually to the portions that were most 
largely composed of manganese-ore. 
If this be the case, then on extending the present excavations along the 
strike it should be found that the ore-band sinks to a greater and greater 
depth below the alluvium, at the same time changing to the manganese- 
silicate-rocks that formed the necks between the upstanding hills or 
hillocks of manganese-ore in the times when the rocks were subjected to 
erosion and not covered by alluvium. 
The deposits oi this group, excluding Parsioni, are situated at dis- 
tances of 5 to 8 miles to the north of the Bengal-Nagpur Railway, to 
which the ore quarried was formerly all carted, the stations used being 
Salwa and Tharsa. A system ot light tramways of 2-foot gauge con- 
structed by the Central India Mining (.ompany now taps ail the deposits 
from Lohdongri eastwards, the ore being carried to Tharsa station. 
This system of tramways also taps the deposits of Group V further to 
the north. The ore from the deposits to the west of Lohdongri is still 
carted to Salwa station, unless any use be made of the newly opened line 
to Ramtek.

The band of manganese-silicate-rock situated in these two village 
areas is exposed at intervals for 2 miles. It starts on the east just inside 
the eastern Parsioni boundary about | a mile from the Pench River and, 
after passing through the town of Parsioni, finishes at the western end in 
the Bansinghi village area. At the eastern end the strike is a little north 
of east, and at the western end slightly north of west. The maximum
