HUGHES : WARDHA VALLEY COAL-FIELD. 



sible deposits. I need, therefore, only summarise the information con- 

 tained in those papers — 



1. The Chanda district surpasses all others iu the Wardha valley 



for richness of iron ore. 



2. The most noted localities are Dewalgaou, Gunjwahi, Lohara, Pipal- 



gaon and Ratnapur. 



3. The most accessible to Warora are Ratnapur, Pipalgaon and 



Lohara ; and of these, Pipalgaon. 



4. The varieties of ore are : at Pipalgaon, compact crystalline haema- 



tite, with some magnetic oxide; at Lohara, the same; at 

 Ratnapur, brown iron ore. 



5. The great value of these main deposits lies in the almost total free- 



dom of their ores from phosphorus; this being almost the only 

 deleterious substance that is not eliminated from iron in the 

 Bessemer converter. 



6. The largest deposit is that of Lohara, but there is also an enor- 



mous amount of iron ore at Pipalgaon. 

 The following analyses illustrate the composition of the various ores 

 collected and examined :—
