would probably approximate to tlie average composition indicated on 
page 697. Dm-ing 1906, a considerable amount of v/ork is said to have 
been done on this deposit by the Central Provinces Prospecting Syndicate. 
Mr. D. Laxminarayan has opened up the alluvial ground occupying the 
breaks in the outcrop of the ore band at different places, especially 
in Jamrapani, and has found ore quite close to the surface. 
The production of ore from these localities is 
shown below : —

3. Sonegaon. 
About I mile south-west of the village there is an outcrop some .300 
yards long that has a strike of about S. 20° W. and rises in one place 
to form a very low hillock. This outcrop is composed of interbanded 
grey quartzite and garnet-rhodonite-quartz-rock (rhodonite-gondite) 
with some spessartite- quartz-rock (gonditR), and a little manganese- 
ore. In one place a dip of 40° to W. 40° N. was seen. The 'country ' 
on the east side of the band is mica-quartz-schist. Nowhere did this 
outcrop seem to be worth working. 
There is another outcrop of manganiferous rocks some 2| miles west- 
south- west of the village, but this (Gilraghat) has been noticed, in 
describing the Ponia-Thirori-Jamrapani ore-belt, of which it forms a part 
(see page 704). 
4. Arjoni and Jam. 
(P. C. DuTT, Burn & Co.) 
A little to the north of the main village of Arjoni (not shown on the 
1-inch map) is the south-east end of an outcrop about 1 mile long, striking 
W. 30° N., of which the south-east half is in Arjoni and the north-west
