MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [pAKT IV : 
to the Kanhan siding situated on the east side of the Kanlifin river 
about a mile outside Kilmthi. 
The ores of Beldongri and Siitak are still carted to 8al\va station, 
but it may pay later on to carry them to a point on the Ramtek Railwaj . 
The ores from the deposits of Groups T and II are carted to Nagpur, 
over distances of 20 miles and upwards along the main road from Chhind- 
\v;tra to Nagpur. Those of Ramdongri cannot be carted in the rains 
as the Kanhan river is then too high ; at other times of the year a tem- 
porary bridge is constructed. There will, however, be a great reductiou 
in the cost of transport of the ores of this part of the district when the 
proposed railway from Nagpur to Clihindwara is constructed, as it will 
then be possible to run out sidings to the various deposits. 
When the majority of the deposits have been connected to the main 
line from Bombay to Calcutta it will be a happy day for the roads of this 
district. At present they are kept in a very bad condition by the passage 
over them of a constant stream of bullock-carts staggering along with 
heavy loads of manganese-ore. 
GROUP I. 
1. Kodegaon. 
2. Gumgaon, 
3. Ramdongri. 
This being the area where I first became acquainted with the Archaean 
manganese-ore deposits, a considerable time was spent in the examination 
of these three localities, with the idea that after carefully working them 
out they would form a key to the interpretation of the many other 
deposits of like origin occurring in the four districts of Chhindwara, 
Nagpur, Bhandara, and Balaghat. As the largest scale map of the 
Nagpur district • is the ^-inch sheet, on which the hills are often 
very imperfectly shown, the three accompanying maps were constructed 
(from a rough prismatic compass survey). 
From the map (Plate 24) it will be seen that there is a range of hills 
stretching for about 5 miles in an east- north- east direction from Kode- 
gaon on the west to Kuthulna on the east. For convenience of descrip- 
tion I have given local names to the separate portions of the ranges and 
numbered the hills and hillocks composing each group. 
On the west the ranges are mere hillocks or very small hills about 
TjO to 100 ieet high, but towards the east they become much higher, 
reaching a maximum, at the Ramdongri H. S. on the east shore of 
the Kanhan river, of about 280 feet, as measured by the aneroid, above the
