514 A. J. M. Atkin— Genesis of Gold Deposits, BarherviUe, B. C. 



While it is at once admitted that the foregoing facts are not 

 in themselves sufficiently correlated to justify the assumption of 

 a meteoric origin for all geysers and most metalliferous solutions, 

 they may nevertheless be considered sufficiently suggestive to give 

 pause to the most imaginative of magmatic secretionists. In view of 

 the undi)ul)ted connection between lieated waters and ore deposition, 

 further detailed and scientific stud3' of these fumarolic areas is 

 greatly to be desired. 



VI. — Some Further Consider.\tions of the Genesis of the Gold 



Deposits of Barkerville, B.C., and the Vicinity. 



By Austin J. R. Atkin, Esq. 



SINCE the publication of my paper " The Genesis of the Gold 

 Deposits of Barkerville," ' the frequencj' with which it has 

 been suggested to me that the gold in the placers spoken of might 

 have been precipitated in situ has led me to place before you the 

 reasons for ascribing to it the origin therein stated.

In propounding the theory of precipitation to explain the 

 occurrence of nuggets in the Australian ' leads' Professor Newberry 

 took into account the fact that it was only at considerable distances 

 from the source of the leads that the larger nuggets were found. 

 He also noted that the greatest accretions of gold were where the 

 wood found in these old channels was most abundant ; that as 

 a rule the gold contained a nucleus of iron ; that it was finer in
