Position and extent. Vancouver Island is 

 situated between latitudes 48° 15^ and 50° 45' N. 

 and longitudes 123° and 128° 30' W. It is the 

 southernmost and the largest of a long chain 

 of islands strung out along the west coast of 

 North America from Washington to farthest 

 Alaska. It is separated from the main land on 

 the southwest by the Straits of San Juan de Fuca, 

 and on the east and northeast by Johnsons'

 is in round figures 450 kilometers long by 130 

 kilometers wide. The part of Renfrew district 

 under consideration lies on the west coast op- 

 posite Cape Flattery and comprises the region 

 of San Juan Harbor. 



Geological formation. Geologically this chain 

 of islands is a partially submerged extension of 

 the coast range of the Pacific States. Van-
