the Jabalpur district. In the early part of 1881 Mr. Trimnell was 

 successful in treating the iron ores in the neighbourhood of Murwara, 

 but the fuel employed was charcoal. No attempt has been made to use 

 Umaria coal, but I have latply been informed that the Government 

 (Central Provinces) intend making a few trials with some best selected 

 pit coal as fuel. Instead of carrying out independent experiments, how- 

 ever, I think the better plan would be to forward ore and fuel to the 

 Barakar iron-works where the whole process of manufacture has been 

 brought under practical control. 



SECTION XIX. — LIMESTONE. 



Limestone is found abundantly in the form of rock limestone, wherever 

 the Lame'ta group is developed. 



The Bijawar formation also yields it; and within the Lora meta- 

 morphic inlier there are beds of crystalline limestone. 



The Lameta limestone varies a great deal, and care must be exercised 

 in its selection if it be intended for use. 



Kankar is freely distributed, but its occurrence in large nodules is 

 restricted to small areas. Tufa or travertine is also met with. 



The following analyses show the average composition of the different 

 lime-bearing sources : —
