always readily given, to visit their properties and publish freely any 
information obtained. I am also deeply grateful to the managers of these 
companies and syndicates, and to the managers of the various mines, 
for the courtesy with which they have in every way facilitated my visits 
to their properties ; for the readiness with which they have answered 
questions, sometimes, perhaps, of too inquisitive a nature ; and lastly 
for the kind way in which they have often personally shown me the main 
features of their deposits, so that I have been able to carry out a detailed 
examination with the salient points already grasped. 
I cannot do better than quote here a remark of that eminent expon- 
ent of the science of ore-deposits, Professor Franz Posepny. In his 
work entitled ' The Genesis of Ore-Deposits ', p. 3, (1902), he sa^s 
' Mining, indeed, constantly furnishes fresh evidences in new openings, but it 
destroys the old at the same time ; and if these are not preserved for science 
before it is too late, they are lost forever. The whole mining industry is in its 
nature transitory ; but the nation, whi^h intrusts to the miner, upon certain con- 
ditions, the extraction of its mineral wealth, has a right to demand that the 
knowledge thus gained at the cost of a part of the national resources shall not be 
lost to science.' 
Now, although most members of the manganese -mining community 
of India may not have read this passage, yet they seem to be imbued 
with the spirit of it. They do not, as a rule, record these ' fresh evid- 
ences ' themselves ; but they are only too willing to draw the attention 
of the geologist to the discovery of what seems to them an interesting 
or important exposure or mineral, and further to facilitate in every way 
his personal visit to the place of interest and examination of the same. 
The fault of the non-recording of every interesting piece of geological 
interest exposed lies perhaps with the geologist, for he is often unable, 
from pre-occupation with other work, to accept an invitation to visit 
the point of interest. This fault is, however, not personal, but due to 
the fact that a comparatively small body of men have the guardianship, 
so to speak, of the mineral resources of an area that is almost as big as a 
continent and out of all proportion to their nimabers. 
If the members of the Indian manganese -mining community find 
this Memoir of interest or value to themselves, I shall be happy if they 
realize that it has only been rendered possible through their cordial 
co-operation and friendly interest. 
The various companies, syndicates and individuals to whom I am 
indebted in the various ways specified above are the following : — 
Bombay Company, Limited ; Central India Mining Company, Limited ; 
Central Provinces Prospecting Syndicate ; Indian Manganese Company,
