The details of these samples are as followfs : — 
Sample 3. — Taken from the stacked talus-ore derived from hill 5 (November 
1903). Composed principally of the fine-gaired braunite-psilomolane mixture. 
Sample d. — Taken from the ore quarried m and from the debris near the top 
of hill 5, where the blocks are very largo (November 1903). Cv)mj)OHcd j)rincipally 
of the fine-grained braunite-i)silomelane mixture, with a certain profjortion of the 
facetted braunitc-ore. Several pieces rather cindery in aiipearanoe. Also a little 
siliceous impurity in one or two pieces. 
Sample 5. — Taken from the outcrop on hill 9 (November 19Q3), composed 
mostly of rather cavernous hard grey fine-grained ore (braunite-psilomelane 
mixture), containing a considerable quantity of soft black powder and sometimes 
little strings of white quartz. 
Sample 6. — Taken from the outcrop and loose blocks of the top of hill 4, down 
its eastern slope, and a little way down its north-north-western slope (November 
1903). Compo'scd of hard grey fine-grained braunite-psilomelane mixture, some 
pieces containing a little spossartite and traces of quartz. 
The above analyses indicate that these ores contain from 50 to 65 
per cent, of braunite, the balance being psilomelane.

4. Risapa. 
5. Nandgondi. 
6. Sitagondi. 
This area includes the cultivated tracts of Risara, and the wild, very 
hilly, and uninhabited, jmigle-clad tracts of Sitagondi and Nandgondi. 
At the time of my visit prospecting licenses over the village of Risara, 
Sugundra, Nandgondi, Maharkund and Chargaon had been taken out 
by Messrs. Ogilvy, Gillanders and Company of Calcutta. I was unable, 
however, to obtain any news of the existence of manganese-ore in any of 
these village areas except Risara. Quite by accident I found outcrops of 
spessartite- bearing rocks in the dense jungles of Sitagondi and Nandgondi, 
and it is probable that a careful search through these Government forests
