2. Deoghur or Byjnath is a small Town in Zillah Beerbhoom, 

 famous for its appearance, the inhabitants chiefly Brahmins. 



The Town is situated on the great primitive Table-land which extends 

 from near Burdwan to the Dunna Ghat in Behar, and which is com- 

 posed of granite, gneiss, serpentine, greenstone, quartz, rock, &c, the 

 gneiss strata are much contorted, often vertical, generally inclined and

 country is pleasing, the land is undulating, well wooded and studded 

 with detached hills of rounded masses of garnetiferous gneiss. The 

 spot where the copper is found is situated in the lands of the village of 

 Byriiki of Tuppeh Deoghur, Saruth of Zillah Beerbhoom, and about
