MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [PaET IV : 
Mr. Young has obtained from this pit some trapezohedrai crystals 
of spessartite, the occurrence of which is of especial interest because 
not a sign of this mineral has been seen in the main Lohdongri quarry, 
although over 100,000 tons of ore have been extracted from it. 
Although the ground between this pit and the main deposit has not 
been examined for ore, yet it seems probable that this occurrence is 
only an extension of the main ore-body. Moreover, someone has dug 
some shallow pits at intervals for about J a mile further to the west, 
in which fragments of loose ore and spessartiferous rock have been found. 
At a point about a mile west of Lohdongri village there is an outcrop 
by the roadside, just on the Lohdongri side of a nilla, of darkened spessar- 
tite- quartz -rock. All the facts enumerated above point to a more or 
less contirmous run of manganiferous rock or manganese-ore between 
Lohdongri and Beldongri, although, in many places, this supposed 
manganiferous band must be buried too deeply beneath the surface to be 
economically workable.

{See Plate 41.) 
This deposit, worked by the Central Lidia Min.ing Company on a 
mining lease, is situated about if miles almost due east of Lohdongri 
village and is about f mile south by east of Kticharwahi village. It 
is situated in cultivated fields and is worked by an excavation in the 
alluvial soil. In the irregular excavation the ore-body was exposed 
for a length of about 100 yards and a width of 92 feet measured horizon- 
tally. Neither wall of the deposit could be seen, so that the full 
thickness had possibly not been exposed.! Taking the average dip as 60°. 
the above horizontal width corresponds to a true thickness of 80 feet. 
The actual dips seen were at 60° — 70° to the S. 5° E. on the south side 
near the west end, curling round to S. 40° E. towards the middle, and 
further along returning to a dip of 55°— 70° to S. 10° E. ; this latter may 
be regarded as corresponding to the average strike of the deposit, namely 
E. 10° N. Some shallow trial pits, which had been put down on the 
extension of the strike to the east, had passed through alluvial clay 
and failed to strike the ore-body ; hence it is possible that the ore-body 
being worked was once a small hill that has been since buried in the 
alluvium of the Sur River. 
1 I revisited this deposit in December 190G. The quarry had then been consider- 
ably deepened (to 60 feet or more in i)laces) and widened and the ' countrj' ' cm the 
south side had been exposed and possibly that on the north as well. If so, the 
figure given above is the true width.
