COAL EXPLORATIONS. 



11 I 



There is as will be seen i foot of coal in the whole section. To 

 form an idea of the nature of such coals, I extracted some of this foot 

 of coal and tested it getting upwards of 35 per cent, of ash. Dr. King's 

 general analysis of the whole seam gave : — 



Moisture ............ 8*2o 



Volatile matter 22*21 



Fixed carbon 25*16 



Ash 44'43 



Perhaps also it will be as well to record that the No. 7 seam is 

 the one exposed near Boniari and therefore 



No, 7 in Dhoramuda _ ' 



borehole, the Bonjari the same as Dr. King's 7 foot seam at 62 feet 



exposu.e. 



deep in his No. 6 borehole. I also sank a small 

 shaft into this exposure and obtained the following section : —

Here again then is an insignificant thickness of coal. A test on 

 the coal alone gave upwards of 35 per cent, of ash. An average 

 analysis throughout the seam is given by Dr. King :— 



Moisture 5"44 



Volatile matter ....... 25*03 



Fixed carbon ....... 29*22 



Ash 39*31
