From the analysis of the flora thus presented it appears that out of 61 specimens fifteen 

 may be excluded for various reasons. The remaining 36 then show the following general 

 distribution. 



Eocene, chiefly Lignite Tertiary 26 



Upper Eocene or Oligocene 17 



Lower Miocene or Oligocene 13 



Wholly Miocene 17 



It further appears that those which favour an altogether Eocene age are 43, while those 

 favouring a Miocene age are 30, and those which are Oligocene within the limits of those two 

 groups, number 80. 



Of those which are wholly Eocene we may note Acer trilobatum produdum, Coryliis 

 macquarrii, Cupressoxylon dawsoni, Ficui asarifoliaf Qrewia crenata, the equally strong type 

 Onoolea sensibilis, Planera crenata, and Taxodium laramianum, eight species in all. On the 

 other hand, of those which are wholly Miocene, there are Nelumhium pygmceum and Ficus 

 populina, only two. The evidence is very strong, therefore, as showing that the beds of the 

 Horsefly are in reality Oligocene, with a much stronger affinity with the Eocene than with 

 the Miocene.

The Kettle River flora is a limited one, embracing only 14 species, with the following
