278 APPENDIX. 



2. The Iron clay bands of the Damuda and Mahadeva Sandstones, sometimes 



though rarely smelted. 



3. The ores extracted from among the beds of the crystalline rocks, which are 



interstratified with the quartzite and hornblende schists. 



4. The ores which are accumulated along fault lines and which are found en- 



closing fragments of the nearest beds and filling hollows and cracks among 

 them. 



To this last class belong the Jaoli and Agaria mines, as well as those of Omur- 

 pani (Tendukhera) and of the Chandgurh country, including Bahin, in all which the 

 vein is worked on, and in some along, the fault line. These are by far the more 

 productive mines : the ore is, chemically, hydrous peroxide, though the anhydrous 

 variety exceptionally occurs. 



No. 3 is the next in importance, commercially. It includes Gungye, Lameta 

 and Punagur and other less important mines. As stated, the ore is geologically con- 

 nected with the old crystalline rocks and more ancient in origin than No. 4, wbichmay 

 have been derived from the decomposed ingredients of these ores which are exclu- 

 sively anhydrous peroxide. 



JSTo. 1 is largely worked in places, as for instance in the Chandgurh and Poonassa 

 country, and may probably be due to the degradation of Nos. 4 and 3. 



No. 2 is very rarely worth working, but is fused in a few places in the hills, 

 where the old slag heaps prove that at some former period a greater number of 

 furnaces existed than are now found. The ore is very impure and requires much 

 selection and cleaning. 



All future developement of the Iron-producing powers of the country must be 

 of course directed to Nos. 3 and 4. 



No. 1 is, on account of the great facility with which it may be extracted, largely 

 used at present as a source of Iron, but is incapable of furnishing a large or con- 

 stant supply, and No. 2, which for the most part scarcely deserves the name of an 

 ore, is worked exclusively among the hills where the great abundance of fuel offers 

 an inducement to the present smelter.
