ticulars concerning metals found in the range of hills described 

 as passing Gudeypore, and running into Ajmeer. They were 

 found in the hills surrounding the ancient city of Ajmeer. He 

 continues : The specimens which I have seen were ores of lead 

 and copper ; and silver, in small quantity, as I am told by the 

 late superintendant of Ajmeer, is associated with the lead. 

 Mines of this last metal are worked to a considerable extent, 

 some of them being seventy yards deep. The ores which I saw 

 were galena and phosphate of lead. Sulphate of lead also occurs 

 there. 



The native method of reducing the metal is at once simple 

 and economical. The ore is pounded very small. It is then 

 mixed with wet cow-dung, and rolled into balls ; and these, af- 

 ter having been dried in the sun, are, with the addition of a 

 small quantity of charcoal, set on fire. The heat produced by 

 this process, with the assistance of the bellows, is sufficient to se- 

 parate the metal, which is then collected for commerce. 



Copper is not extensively worked. To private individuals^ 

 the expense and risk attending the operation are too great ; but 

 were government to hold out sufficient encouragement, I have 

 no doubt that, from the specimens which I have seen, mines of 

 this metal might be worked to great advantage. The ore was 

 the green carbonate of copper. The rocks in which these me- 

 tals occur are primitive ; and I have seen specimens of granite 

 from the hills in which the veins of lead and copper are ob- 

 served. The veins are described as being very numerous, and 

 rich. The mica of the granite was olive-green, apparently 

 tinged with copper. The felspar and quartz were in large con- 

 cretions. Steatite was also found associated with these.

T. HERE are few subjects in which the mind may not lose itself. 

 A master spirit may grasp great and important truths, and rove 

 over the face of existence, with a freedom that may seem to be- 

 speak an all-illuminating power ; but when he confines his ener- 

 gies to a point, and strives to scan the mysteries of any minute
