CHANDA DISTRICT. 33 



As may be inferred, the quality of the coals in such a large seam 

 varies. There are some bands of very fair excellence. The average 

 composition of 32 specimens brought up from the bore-hole is about 

 the same as that of the Telwasa coals—

These averages are given for the purpose of general comparison only, 

 and do not prove the practical superiority of one seam over another, as 

 it is quite possible that a band of workable coal in the seam giving the 

 lowest average may be more fitted for a special purpose than any found 

 in the other. 



"When in full working order, about 70 tons of coal were raised 

 monthly at the Mayo colliery, some of which was used for the steam 

 borer, aud some by the Great Indian Peninsula Railway. The results 

 obtained with it were sufficiently assuring to show that the coal might 

 be relied upon for steam service. The galleries were driven into the 

 upper portion of the seam. The pit is now abandoned owing to the 

 advantage of position possessed by the Warora basin. 



Two additional bore-holes were put down, one nearly due west of 



Ghugus, and one at the edge of the Wardha, south 

 Nokdra seam 90' 8". 



of Nokora, to prove the variation in the seam.
