MANGANKSE Dtei'OSlTS OF INDIA : DESCRIPTIVE. [PaET IV : 
Puri District. 
Amongst some specimens of building stones received from the Dis- 
trict Engineer, Khurda, two blocks of somewhat decomposed khondalite 
from Khijerimudia, 3 miles south of Jatni, shew spots and streaks of 
soft brownish black manganese oxide ; whilst a specimen of ferruginous 
laterite fiom Bhomitika, 2 miles east of Jatni, shows dark brownish black 
manganiferous spots. 
Singhbhum District. 
In January 1905 I spent a few days in this district examining some 
^. ^ deposits of manganese-ore that had been recently 
prospected near Chaibasa by Messrs. Hoare, Miller 
& Co., and Messieurs Jambon and Cie., both of Calcutta. Since 
then these firms have relinquished practically all their interests and the 
Madhu Lall Doogar Mining Syndicate of Kamthi has obtained the 
concessions. Prospecting in other parts of the district has resulted in the 
discovery of other occurrences of manganese-ore, amongst them that on 
Leda Hill found by Mr. R. Saubolle working on behalf of Messrs. 
Martin & Co., Calcutta. In January 1908 I was able to visit Leda 
Hill, and Tutugutu, near Chaibasa, not previously examined. The 
remarks in the following paragraphs refer to the deposits of the 
Chaibasa area, unless otherwise stated. 
Most of the localities for manganese investigated by the prospectors 
of the above firms were originally discovered by V. Ball,l who men- 
tions the occurrence of iron-ores ' in a number of lodes and veias which 
occur in the sub-metamorphic rocks in the neighbourhood of, and to the 
west of, the town of Chaibasa Many of them, however, give great 
promise of being rich in manganese.' He notices a ' well-marked ridge of 
this manganiferous ore mixed with vein quartz south of Chaibasa and east- 
40rth-eastof Purana Chaibasa,' and a somewhat similar outcrop of brown 
hematite near Tjagia, some of this ore being rich in manganese. The 
two firms first mentioned took out prospecting licenses in August and 
September, 1904, respectively, and carried out a considerable amount of 
surface excavation in the form of pits up to 10 feet deep, and shallow 
trenches. This enabled me to form a very good idea as to the mode of 
occurrence and origin of these ores.
