112 READER: REPORT ON THE RAMPUR COAL-FIELD. 



These two seams just discussed (Nos. i and 7) may be taken as 

 typical of the other four (Nos. 3, 4, 5, and 6), and all can therefore 

 be dismissed from further consideration. 



This leaves us then with only two (Nos. 2 and 8) coal-seams of 

 workable thickness in the Dhoramuda borehole. No. 2 described in 

 the Record as 16 feet of shaly coal appears from the core to be —

CHAPTER IV. 

 Workable thicknesses of coal proved. 

 So far then only four seams of coal out of the many struck have 

 upon examination proved to be of workable thickness. Beginning 

 at the top and in descending order these are :— 



i° The seam proved in the Dhoramuda borehole at a depth 



of 309I feet, the section of which is given just above 



and is shewn to be composed of 7 feet 3$ inches coal 



with one foot of shale interbedded. 



2° The seam proved in the Dhoramuda borehole at a depth 



of 768 feet, containing four feet of coal. 

 3 The seam proved in the Kodopali borehole <it a depth of 

 3525 feet, composed of 7 feet 1 inch of coal with 

 one foot of shale interbedded. 

 4 The Eeb bridge seam of which the best section obtained 

 shows 7 feet 10 inches of coal with 8 inches of bat (hard 

 bituminous shale) interbedded. 



I have made careful analyses of these four

seams and tested their calorific powers. 

 It must be remembered, however, that the samples of Nos. I, 2» 

 and 3 seams, of which the analyses were made, were taken from the 

 cores of the diamond drill boreholes put down in February 1899
