3. Sondenhalli (Solid Hill Mine). 
This hill is situated about 1^ miles W. by a little N. of Msivinhalli 
village. Several pits on the N. E. slope of the hill show yellow ochre 
with patches of pyrolusite and hard hmonite. The dip seen in one 
place was about 60° to W. S. W. On the top of the next hillock to 
the N. W. of this one there is a lateritoid outcrop which, when broken 
into, often shows remains of quartz or quartzite, and in one place 
showed manganese-ore, this being impure psilomelane. In another 
place an opening in this lateritoid showed a considerable quantity of 
manganese- ore, consisting of a mixture of pyrolusite and psilomelane ; 
frequently the ore contained patches of a soapy mineral, probably 
representing some phyllites of talcoid appearance seen close to the 
latentoid. The rocks seen between this deposit and the Temple Hill 
mine some 2^ miles to the south are banded ferruginous (magnetite 
and limonite) quartzites, often containing a fibrous amphibole, which is 
colourless under the microscope ; and soft sericitoid phyllites. The 
dips in these rocks are sometimes to the east and sometimes to the 
west side of the strike, which is N. N. W. 
4. Muskondli (Rowe's Mine). 
This deposit is situated on low ground about a mile N. 15°E. of 
Karekurchi village. A trench, deepened in places into small pits, shows 
rubble for the first 2 or 3 feet, and then below this wad and ochre with 
abundant residual patches of white quartzite. This quartzite is often 
seen partly replaced by manganese oxide and limonite. The small 
quantity of ore extracted consists mostly of cavernous pvrolusite, with 
occasional pieces of harder ore. Close to this excavation is an outcrop 
of quartz or quartzite partly replaced by limonite. 
5. KarekuFchi (Camp Mine). 
This about h mile E.1G°N. of the village of the same name and 
is on very slightly elevated ground lying to the east of the range of 
hills in which Nos. 3 and 6 lie. The outcrop takes the forms cf a lateri- 
toid rock composed largely of limonite with patches of yellow ockre 
and rarer patches of manganese-ore. From the excavations, which 
have in one place reached a depth of 15 to 20 feet, it is seen that the 
ores occur in irregular patches, partly in this lateritoid rock of Hmonite
