DISTRIBUTION OF THE STUMP LAKE FLORA. 



The obvious conclusion to be derived from the distribution here shown is to the effect 

 that the beds are of Lower Miocene or Oligocene age. 



HORSEFLY RIVER. 



The flora of the Horsefly river has been worked out particularly through the recent 

 collections of Lambe in 1906. As now known it embraces fifty-one representatives, and, as 

 one of the largest from any single locality, it affords a clear idea of the character of the 

 vegetation and its relation to other Tertiary floras.
