HUGHES : WARDHA VALLEY COAL-FIELD. 



No determination of the sulphur in the Pisgaon coal was made, but, 

 judging from appearance, it ought to be freer from this substance than 

 the coal at Warora. It occurs more in nodules than in small crystals, 

 and might with much more facility be eliminated by mechanical means. 



For the Warora coal, Mr. Ness' result of only "25 per cent, of sulphur 

 strikes me as being much too small a proportion, and 2*85 per cent, is 

 perhaps too high an average^ the sample that yielded that amount being 

 probably an exceptionally dirty one. 



(d.) Moisture. — The presence of a large amount of moisture is 



obviously objectionable, not merely as being so much dead weight, but 



as actually reducing the temperature obtainable by combustion. The 



ineffective portion of the coal is represented by the water and the ash, 



and this amounts to —

6-9 + 38-4 = 45-3 



The coals of the Wardha valley and those of the (jodavari hold 



much more water than those in the Raniganj basin, as may be seen 



in the following comparative tables.
