south of S&kri, and the Talchirs and Barakars, there remain fully 

 80 square miles of probable productive coal lands. An average of 15 

 feet may be admitted for 20 square miles, and 30 feet for sixty miles, 

 making a total of 2,100 millions of tons. 



Direct evidence of the occurrence of coal has been obtained through- 

 out 13 miles of country from Wun to Papiir ; and for 10 miles from 

 Junara to Chicholi (opposite Nokora), and assuming as available all that 

 can be won at 500 feet, we shall have between Wun and Papur — 7 

 square miles, average thickness 15 feet=105 millions of tons of coal. 

 Deducting half for loss in working, 50 millions of tons remain. Between 

 Junara and Chicholi, 5 square miles, average thickness 30 feet=150 

 millions of tons of coal. Deducting one-half as above, we have 75 

 millions of tons. I do not uphold my estimates as being unassailable, 

 for there is a wonderful protean power in figures when dealing with total 

 and available quantities of coal ; but I believe the above numbers re- 

 present the minimum available tons of coal at a depth of 500 feet in the 

 area to which they refer. 



The coal seam in the Nizam's dominions near Sasti and Paoni has 



only been proved over a small area. One and a

half square miles is the utmost that can be ad- 

 mitted, but an average of 40 feet of coal may be taken. This gives 60 

 millions as the total quantity, or 30 millions as available.
