METAMOUPHIC SERIES. / 



are covered with black soil, much mixed with stones. Near Nagpur 

 the greater portion of the country is cleared, but the amount of jungle 

 increases with the distance from the station, until, at a distance of 12 to 

 15 miles, it covers a considerable proportion of the surface. Southward 

 the country is similar to that to the west. 



To the south-east, east, and north-east the surface is, for the most 

 part, a plain covered with the alluvial deposits of the Kanhan and its 

 tributaries. This plain extends to the north-east for some distance beyond 

 Kamthi, and the sandstones near that station are only exposed in a few 

 places on the left (north-east) bank of the river. To the north and 

 north-west the same plain of alluvium is continued, but from its surface 

 in several places, rise hills of sandstone and metamorphic rocks.

As already observed, no special attention was paid to these rocks. 



They must occupy all the country to the east and north-east of 



Nagpur for a great distance, but, near the city, they are, in general, 



completely concealed by alluvium. They are

seen at the base of Sitabaldi hill around the 



railway station. Here the rocks are gneiss, very much decomposed 

 at the surface, and it must be their decomposed appearance, and the 

 resemblance to a soft sandstone thereby produced, which led Mr. Hislop 

 to a belief in their being an altered form of the overlying sedi- 

 mentary rock. They are also seen, but only for a very short distance,
