248 THE CANADIAN NATURALIST. [Vol. Vlii. 



Miocene Period. — Immediately succeeding considerable moun- 

 tain upheaval, and closed by basalt flows of the interior. Coast 

 at least during part of this period somewhat lower than at pre- 

 sent. 



Pliocene Period. — Land elevated at least about 900 feet 

 above the present sea line for part or the whole of this period. 



Glacial Period. — At one or more epochs during this period 

 land much depressed ; at one time probably over 5,000 feet. 



The country considerably below the present level when the 

 glacier of the Strait of Georgia finally retreated from the south- 

 eastern part of Vancouver Island. 



Post Glacial and Modern. — Reelevation to height probably 

 200 or 300 feet greater than at present, followed by depression to 

 near the present level, with probably many changes of small 

 amount, and perhaps one or more rather important movements 

 as indicated by the Indian stories. Lastly, somewhat rapid 

 depression of perhaps ten or fifteen feet during the latter part of 

 last century, a movement which may still be slowly going on. 



Subsequent examination of this part of the Pacific coast may 

 enable us to add many details to this necessarily somewhat im- 

 perfect scheme.
