In addition to the manganese-ores, there are to the found in several 
places blackened or manganized slates. Of such 
• • ■ places the following may be particularized : — (1) the 
stream bed immediately west of hill 690 ft. and (2) the points where the 
road crosses two water-courses just to the west of Jaban.' Thin slices of 
these manganized slates examined under the microscope show that the 
blackening is due to their impregnation by manganese oxide in the form 
of thickly scattered minute granules or dust. 
R^jpipla State. 
The Gaaetteer2 records a trace of manganese in an analysis of some 
iron slag found as large mounds to the W. of Limodra about 25 miles 
W. of Nandod in Raipipla. 
Ratnagiri District. 
Manganese -ores are said to occur in the trap rock — the Deccan Trap 
— of this district, 3 but no authority for this statement is given. Mr. 
B. G. Shastree 4 gives a description of an iron-ore from near Malvan 
containing a trace of manganese. Malvan is on the metamorphic and 
crystalline rocks. 
Satara District. 
The occurrence of manganese-ores in this district was first brought 
to the notice of the Geological Survey of India by 
History. q p s^j-^giyf,^ reported on the manganese- 
ores of the Mahabaleshwar plateau on behalf of Messrs. McLeod 
and Co. of Calcutta. This firm kindly allowed me to peruse and 
make use of Mr. Wright's report. I must here record my indebtedness 
to Mr. K. C. Cowasji of Mahabaleshwar, who kindly showed me the more 
important of the localities where manganese-ores had been found.
