ECONOMIC GEOLOGY. 289 



This percentage of fixed carbon seems exceptionally high, as the following 

 analysis of the seam excavated by myself, 17 feet thick, at'Begarmul near Juswal 

 will make evident. The exposure was laid bare by Sub- Assistant Hira Lai 

 under my direction and the samples taken carefully by myself at intervals of

From the above it will be seen that the average percentage of ash in the 

 first 9 feet of 46-03 is altogether prohibitive. At the 10th foot there is a decided 

 improvement, but below this the average ash percentage is again as high as 

 31-95 (see tri-monthly notes, Records, Geological Survey of India, Vol. XXVI, 

 Pt. 3, p. 107), so that so far as this outcrop is concerned the coal would be of no 

 useexcept for brick and lime burning. Whether it would improve towards the centre 

 of the hill is a question for the engineer to settle. 



From many observations of this coal band and its constant associate the 

 , . variegated sandstone at a great many places, it is my 



broken continuity and opinion, as stated in my preliminary note on the subject, 1 

 variable thickness of that though the band is continuous in a general way 

 it has been so kneaded up with the shaly parts of the 

 band, so sheared in places and crushed out into a thin bed here, and swelled out 

 into a thick one there, that it cannot be relied on as occurring everywhere at its 

 proper horizon in the sequence of the rocks.
