projection at the surface of the summits of hills now practically sub- 
merged in alluvium. The deposits of groups I and IV of the classifica- 
tion given below occur in this manner. But in the northern part of 
the zone, though bands and patches of alluvium are found, hilly and 
densely jungle-clad country predominates ; the deposits of groups II, 
III, V, and VI are characterized by this type of country. According 
to reports there must be — in the wild region starting from Chorbaoli 
and extending to the west, north, and north-east — a considerable quantity 
of manganese-ore ; but unfortunately I had no time to do more than pay 
a flying visit to Mandvi Bir and Junawani to the west-north-west of 
Chorbaoli, the remainder of the jungles being untouched. 
The district is drained by the Kanhan, the Pench and the Sur, the 
Kanhan and Sur flowing direct into the Wainganga, whilst the Pench 
is a tributary of the Kanhan. 
In describing these deposits in more or less detail according to their 
.,. f interest and importance, it will be convenient 
(/lassiiication oi the _ •- ' 
deposits. to divide them into two classes according to the 
mode of occurrence of the ore, and to divide the classes into groups ac- 
cording to the geographical distribution of the deposits. The classes 
are as follows : — 
Class I. — Deposits characterized by the association of spessartite 
and rhodonite — one or both — with the ore, the ' country ' 
being gneiss, schist, or quartzite. 
Class II. — Deposits characterized by the association of piedmontite 
with the ore, the ' country ' being crystalline limestone. 
These classes can be divided into groups as follows : —
