Bhiitridon, where there is some manganese-laterite composed mainly of 
wad, for an account of which see page 8.'50. This laterite is, however, 
closely associated with the surface-breccia ted Gosalpur (|uartzite. and is 
hence only doubtfully to be regarded as true later ite. Also see Mallet, 
Rec. G. S. /.,XII,p.i)9; and XVI, pp. 116-118. 
Turning now to the economic prospects of the ores of this 
district, and taking no account of the 
Economic value of the ^ateritic Ores, which are of little value, there 
deposits. . 1 , 
are the following ores to be considered : — mic- 
aceous hematite, manganiferous hematite, manganiferous limonite, 
psilomelane, and pyrolusite. As far as I could tell from the evidence 
it did not seem probable that any one of these ores was 
obtainable in large quantity. The micaceo^is hematite, which 
is the only ore not of secondary origin, is very much interbanded 
with jasper, although sometimes present in beds or layers of sufficient 
thickness to be of possible value. The manganiferous hematite being 
derived from this is naturally present in still smaller quantities. The 
manganiferous limonites occur in some quantity capping some of the 
ridges, and are to be considered as the best examples of lateritoid in 
this area. The psHomelane is the final product of the series of changes, 
of which the first is the conversion of ordinary hematite into 
manganiferous hematite, and as such is not found in any very large 
quantity, although it is possible that a considerable accumulation 
of this mineral may be found at one or two spots. The fyrolusite seems 
to be present in fair quantities at one or two localities, notably 
Mansakra and Gosalpur, and it is possible that a fair amount of it 
may be obtained if these deposits are ever carefully opened up. 
Apart from their irregular mode of occurrence, these ores suffer from a 
great variability of composition, due to the way in which they have been 
formed. They are also in many cases extremely phosphoric. The best 
prospect of their being worked at a profit would exist if iron works 
were set up to treat the iron ores of the Agaria and Jauli areas 
of this district.! The ores of the Sihora and Gosalpur areas could
