212 Note on the Zinc Mines of Jdwar. [No. 3. 



of large blocks of red crystalline granite contained in a breccia com- 

 posed of limestone cementing quartz and red felspar ; the sand of the 

 bed was similar to that of most other rivers that I have seen, taking 

 their rise from the trap hills and flowing through granite country ; con- 

 sisting of the debris of those two rocks as well as calcedonies and 

 land shells of three sorts, buccinum, helix and pusilla, the right bank of 

 the river resembled exactly that at Ramaleddypett, being lofty and 

 composed of the black cotton soil. I passed over other ranges of the 

 trap, of low height, until our descent into the plain through which 

 the Mubnar passes, the right bank of which is also very steep. 



At Adainaor the granite for more than one-half the height of the 

 hill, and covered at the top by a very compact greenstone with crystals 

 of felspar, and a few cavities not filled with any substance. The course 

 of these trap hills was very distinctly seen from this point due E.

Notes on the Zinc Mines of Jdwar, by Captain J. C. Brooke, Mewar 



Bheel Corps. 



I have forwarded to your address by dawk banghy a box containing 

 specimens of ore, and of the metal extracted therefrom, found between 

 Kherwara and Udypura, and shall feel much obliged by your procur- 

 ing me an analysis of the same, and information as to the composition 

 of the metal* and the best method of smelting the ore. As a descrip- 

 tion of the place where it is found may prove interesting, I send you a 

 few notes concerning it, and the little information I have been able to 

 obtain of the former methods of working the mines. 



2nd. The hilly country of Mewar has always been known to abound 

 in metalliferous ores, and it is supposed that the produce resulting 

 therefrom was one of the sources of wealth, by which former Ranas of 

 Udypura, were enabled to contend successfully for so many years 

 against the might and power of the Delhi emperors. The most cele- 

 brated of these mines and which were worked to the greatest advantage 



* Zinc : the specimens sent are very small, and apparently contain very little 

 metal. — Eds.
