On the Coal Fields and Coal Production of India. 508 
of the Indian coal-measures, and associated younger rocks which 
may conceal coal-measures, has been drawn up by my colleague, 
Mr. Hughes:—* 
Godavari and affluents, - - 11,000 square miles. 
Sone, : . 8,000 9 
Sirguja and Orissa, Sen ; . 4,500 5 
Assam, > : . 98,000 on 
Narbuda and affluents, > . 38,500 7 
Damuda, . : : . 2,000 is 
Rajmahal area, . - 5 300 39 
Unsurveyed, &e., : . 2,700 a 
35,000 : 
For the sake of comparison other countries with greater areas 
are enumerated :— 
United States, . - c 500,000 square miles. 
China, . c ° ; 400,000 x 
Australia, : 5 c 240,000 7 
India comes next or fourth on the list. Although I believe 
Mr. Hughes’ estimates require some modifications in detail, still 
the total cannot be far from correct, and 30,000 square miles 
might, I think, perhaps be safely adopted as a minimum.
