Mysore. 
On page 420 it is mentioned that the first definite account of the 
W Ainslie T J New. occurrence of manganese-ores in India refers 
bold, and the Mysore to the find near Kumari in the Nagpur 
Geological Department. district of the Central Provinces, noticed by 
Jenkins in 1829. It is to be noticed, however, that Dr. W. Ainslie i , in 
1813, says that this metal ' it is to be presumed, is not common in India. 
Captain Arthur, however, informs me that he found it in Mysore, 
massive, in an indurated ochre, combined with oxide of iron'. Newbold 2 
also referred to the occurrence of ores'of manganese in this State as 
early as 1840, whilst manganese-ores from Bangalore were exhibited 
at the Madras Exhibitions of 1855 and 1857 3. There was no definite 
knowledge of the actual locality of any deposit of manganese- ore in 
Mysore State, however, until 1899, when Mr. H. Kelsall Slater, of the 
Mysore Geological Department, found some loose pieces of manganese- 
ore in the bed of a stream some 3 miles north-north-west of Kumsi in 
the Shimoga district 4. Mr. Slater also seems to have been the first to 
find manganese-ores at Shankargudda. HoshaUi, Shiddarhalli, Gangur, 
and near Shikarpur, in the same district ; and in the Kadur district, 
immediately to the east of Shiddarhalli ^. In the Chitaldrug district 
manganese-ores seem to have been first discovered (also in 1899) by 
Dr. W. F. Smeeth and Mr. Sambasiva Iyer, in the Iplara Hills near 
Madadkere 6, and later by Mr. P. Sampat Iyengar ' at several localities 
in the soft clays and lithomarges of the Chitaldrug belt of Dharwar rocks .
