This analysis shows very clearly that the flora of Kettle river is composed of elements 

 which are practically unknown elsewhere, with the exception of Cupressoxylon macroearpoides 

 and Cyperites haydenii. It is therefore evident that these two are the only species upon 

 which to base conclusions, a procedure which would be unsafe without further corroborative 

 evidence. With respect to Cupressoxylon, it has been shown that the only locality hitherto 

 known is to be found in the Cretaceous of the South Saskatchewan river, near Medicine 

 Hat. This would have a tendency to show that the formation in question must be early 

 Eocene, probably of Fort Union age. Cyperites haydenii has been found in no other 

 Canadian locality, but it has been recognized by Lesquereux in the Green River group of 

 "Wyoming. It is a species of somewhat rare occurrence, and its testimony affords only 

 limited evidence of the age of the formation in which it is now found. So far as this may 

 be relied upon, however, it indicates very definitely an Upper Eocene or Oligocene age. 



"With respect to the other five species upon which conclusions might be based, were 

 they found elsewhere, all that can be said of them is that their general facies appear to 

 be later than the Eort Union group, but whether Upper Eocene or Lower Miocene it is 

 impossible to say. On the basis of the evidence available it would probably be safe to 

 assign the Kettle River beds, provisionally, to the Upper Eocene or Oligocene. 



NINE-MILE CREEK. 



Another flora of very limited extent is that from Mne-mile creek on the Sim- 

 ilkameen river, and from the geographical relations of the two this has been assumed 

 to be of the same age as that of Whipsaw creek. But a separate analysis is desirable. 

 Only 13 forms are known.
