 the seam crops in the quarry, and the following figures show the relative 

 percentages of volatile matter, fixed carbon, and ash in the several 

 bands into which the seam was divisible :—

The bright soft coals C and E are excellent in quality, and I am 

 Gas coal. strongly of opinion that they would yield a fair 



Bands C and E. amount of gas for illuminating purposes. The 

 best coal supplied from the Raniganj field for the use of the Oriental 

 Gas Company of Calcutta yields between 9,000 and 10,000 cubic feet of 

 gas to the ton, and judging from the appearance of the bands C and E, 

 they seem quite capable of giving the same quantity. 



The band indicated as D would have to be 

 picked out, as it clinkers readily. 

 The band F is scarcely within the limit of coal, and it was analysed 

 in view of its capability as an oil-producing mate- 

 rial. It yielded about 15 per cent, of oils and 



tarry matter.
