From the analysis thus presented it appears that there are nine cases of Lignite 

 Tertiary plants against six for the Miocene ; but in the Oligocene there are ten cases, of which 

 te:n are Upper Eocene and seven also Lower Miocene. Hence, in spite of Carpinus grandis, 

 which is chiefly Miocene, and of Sequoia avgustifoUa which is wholly Miocene, it must be 

 concluded that the evidence is strongly in favour of an Oligocene age, with a pronounced 

 tendency toward an Eocene, rather than a Miocene, affinity. . It must, therefore, be concluded 

 that the horizon indicated is Lower Oligocene or Upper Eocene, a conclusion which makes 

 the flora agree with that of Nine-mile creek. 



TULAMBEN OR NORTH SIMILKAMEBN RIVER. 



The flora of the Tulameen river is the third largest of the entire series, comprising 4'7 

 species and genera. Its geographical position would lead to the inference that it must be 

 essentially the same as for Nine-mile creek and the Similkameen river as a whole. The 

 following analysis will show its relations.
