Future prospects of the manganese industry in India. 
In the preceding paragraphs I have had occasion to make several 
^ ^ references to the production or output from the

deposits of the different operators working man- 
ganese-ore deposits in India. It will therefore be convenient to give 
here the detailed figures of production of manganese-ore in India. The 
only figures ordinarily accessible are those given in the Annual Reports 
of the Chief ^Inspector of Mines and the Annual Reviews and Statistics 
of Mineral Production in India. In the case of the Chief Inspector of 
Mines the figures are supplied direct by the local mine operators ; whilst 
in the case of the ' Mineral Production ' the figures are obtained from the 
provincial governments, to whom they are supplied by the mine operators. 
The figures as published are not detailed, for although they show the 
output of each district and province, they do not show the output of each 
deposit. It is, however, a matter of considerable interest to know how 
the output is distributed among the various deposits. Hence I have 
obtained from the mine operators detailed figures of production, given 
separately for each deposit, as far as they have been kept. These are 
given in tables 28 to 34 on the following pages, whilst in table 3G are 
given the yearly totals for the producing provinces as they have appeared 
in the ' Mineral Production '. 
It wiU be seen that my totals differ in many respects from those 
given in the ' Mineral Production'. This is due to various causes. In 
the first place, according to ' The Indian Mines Act, 1901', no working 
is ofl&cially regarded as a mine unless it has been worked to a depth of 
20 feet, or extends beneath the superjacent ground. And unless a
