During the field season of 1902-03 I found several occurrences 
of manganese-ore in this district. Since that time, however, the 
boundaries between this district and Nimar have been altered, with 
the result that all the occurrences now lie within the Nimar district — 
under which heading they are noticed — with the exception of Sontulai 
in the Harda tahsil. 
In December 1902, 1 found, in the middle of the road at the west 
end of the village, an outcrop of some impure 
' ™ " black wad, weathering brown, and apparently

Bijawar age. The strike is E. N. E. with a moderate dip to the south 
side. The outcrop was of small extent, but the ore may continue 
under the soil in either direction along the strike. A specimen was 
sent to the Geological Survey office and found by Mr. Blyth to contain
