LEAD — LIME. 83 



but he has no guarantee that the bidding may not go above the real 

 value of the mine. I think that if permission were given to work any 

 of the deserted mines free for a year, so as to allow the miners fairly to 

 test their value, and after that leases were granted for a term of years 

 by tender or auction, men would be found willing to reopen some of 

 them. 



Lead. 



I have no information of lead having ever been worked anywhere 

 in the present area. I observed, however, an indication of the metal in 

 the Sakkam river, in the shape of a boulder composed of garnet and 

 hornblende, containing some galena, with pyrites and magnetite dis- 

 seminated through it. The boulder, of course, was washed from the upper 

 part of the stream.

Lime. 



There are three sources from which lime is procurable in the area 

 under discussion, namely, from the dolomite of the Baxa series, from 

 the impure limestone beds of the Tertiaries, and from calcareous tufa. 

 It is the last rock only that is, or, I believe, ever has been, burned for 

 lime.
