CHAPTERI. 



GENERAL REMARKS. 



Section I. — Previous Observers. 



The earliest reference that I can find connected with the Wardha 

 valley coal-field is in the 3rd volume of the Glean- 



wStalfe^oT * ™& in Science for 1831 >* where attention is drawn 

 to the circumstance of coal oceuring in the banks 

 of the river "Wardha. A sample analysed at the Calcutta Assay Office 

 gave (after exclusion of water, which amounted to 7*8 per cent.) : — 



Carbon ... ... ... ... ••• 43"8 



Volatile matter ... ... ... ... 33*7 



Ash ... ... ... ... ... 22-5 



Total ... 100-0 



Specific gravity, 1-457. As there was no incentive in those days 

 to work this coal, the announcement of its existence was accepted as a 

 fact, and then appears to have been forgotten.
