This deposit is situated about | mile south -south -east of the south-east 
end of the Mansar-Chargaon ore-band, of which it is probably a continua- 
tion. 
The manganese-ore has been obtained from a pit dug in the alluvial 
soil of the fields in which the deposit occurs. This, at the time of my 
visit, was half full of water, and the only rock in situ that could be seen 
had a dip of 50° to 60° to N. 35° E. This consisted of a massive band of 
spessartite-rock and greyish quartzite with some soft manganese-ore, and 
rested upon a rock composed of interbanded quartzite and spessartite- 
bearing quartzite partly altered to manganese-ore. Everywhere else the 
pit showed brown clay containing in places loose fragments and pisoUtic 
concretions of manganese-ore. A second pit showed similar alluvial 
accumulations. By the side of the first pit there was stacked a heap of 
good hard grey ore, obtained, no doubt, in situ from below the present 
water-level. A large proportion of the ore was like the hard variety found 
at Kandri and the remainder was a light bluish grey psilomelane contain- 
ing scattered bright shining facets. A piece of this, which is, of course, 
not typical of the deposit, was analysed at the Imperial Institute with the 
following result : —
