The extensive distribution of iron ores of good quality, is the 

 leading feature of Indian mineralogy. These are found in great 

 abundance in every range of hills, in some of which they have been 

 worked on a very limited scale, but with great success, for long periods 

 of time. In several instances, beds of coal occur contiguous to them, 

 as at Hoshungabad, Palamow, Sheregur in the Burdwan district, on the 

 Adjai, seventy miles south of Boglepore, Serrareem, and Cherrapoonjee. 



The iron districts, Marwar, Bundelkund, a portion of Malwa, Behar, 

 and Sambhulpore,* are situated within the limits of the great sandstone 

 formation with which the coal measures of India are associated. It 

 extends in a broad band across the centre of Hindoostan, from 

 the valley of Assam westward, to that of the Indus, and it is probable 

 that coal will be found in various parts of this formation, and suffi- 

 ciently near to these deposits of iron, to render them extensively 

 available for economical purposes. In the districts of Saugur, Jabul- 

 pore, and in the valley of the Nerbudda, limestone also occurs, the con- 

 nection of which is important, as upon the union of these three sub- 

 stances, the success of iron-works depends. 



This extensive sandstone tract, presents also another source of inter- 

 est. In it the diamond mines of Punnah in Bundelkund are situated, and 

 the strata here are believed to be identical with those containing the dia- 

 mond breccia of the EUore district, and of Cadapah, on the Pennar. These 



* Captain Ouseley discovered a rich field of excellent coal on the banks of the 

 Hurdah (Hutsoo of the maps) in last November. iTi
