SEVENTH AND EIGHTH BEDS. 



It is said that on the opposite sides of the marsh before- 

 mentioned, there are two more beds, affording large 

 quantities of that ore, whicli has the pavonine tarnish. 



NINTH AND TENTH BEDS. 



I heard of these two beds, and saw the ore from one, 

 which was excellent, but cannot describe their localities. 



Before I conclude this note, some notice shall be taken 

 of two reports which a])pear to be in circulation. One on 

 the discovery of copper in the neighbourhood of the works, 

 the other on the probable discovery of coal, both said to 

 liave had their origin with Dr. Bigsby. With regard to 

 the first report, it might very well be true, as the geolo- 

 gical relations of that ore agree with those of the country 

 it is said to occur in ; moreover the native copper of the 

 copper mountains, in this (piarter of the globe, has fre- 

 (juently a matrix of epidole. I, however, saw no copper 

 ore, neither, 1 think, did Dr. Bigsby, or he would have 

 mentioned it in someof his geological papers. 



As to the occurrence of coal, one species of it, anthracite, 

 (the best adapted, when mixed with a little charcoal, for 

 femelting iron) might be found. 1 met with nothing, how- 

 ever, to indicate the probability of finding it. \V'ilh regard 

 to bituminous coal, it is very propable that it will be met 

 with in this jiart of Uj)j)er Canada, if it preserve in this 

 country the same geological relations it does in Europe. 



Among the prizes offered by the Society, is one lor the 

 discovery of coal. It would have been within riacli, had it 

 been offered lor the best essay on the probability, or the 

 improbability of finding it. 



However im|)erfcct the foregoing description maybe, I
