Concerning the coast and islands we find first Dr. Ells' Report 

 on Graham Island which appeared in 1904. The stratigraphie 

 column is here divided only into Post-Tertiary, Cretaceous, and 

 Igneous Rocks comprising Pre-Cretaceous and later Tertiary. Next 

 comes the Le Roy report on the more southerly coast and islands in 

 1908, containing a table which indicates only slight advances on 

 previous determinations. This table is given below: — • 



leroy's classification of the strata of the coast and 

 islands of british columbia 



The great advances in stratigraphie subdivision accomplished 

 between that time and the present may be seen by comparing with 

 the above the excellent table for Queen Charlotte island given by J. D. 

 MacKenzie in 1916 and that given by Clapp for the Nanaimo Map 

 Area in 1914. 



MacKenzie 's table is too extended for reproduction here; it gives 

 not only the sequence in Queen Charlotte island but correlations
