VOLUME I. 



177. On the Fossils of the Coal-Bearing deposits of the Queen Charlotte 

 Islands collected by Dr. Gr. M. Dawson in 1878. 



INTRODUCTORY EEMARKE. 



In 1872 Mr. James Eichardson visited the Queen Charlotte Islands 

 on behalf of the Geological Survey of Canada and spent a few days in 

 the examination of the Coal mines at Cowgitz and of the geological 

 structure of Skidegate Inlet. A description of his observations on this 

 occasion will be found on pages 56-65 of the Report of Progress of the 

 Survey for 1872-73. As pointed out in the first part of the present 

 volume, in which the species were described and figured, the small 

 series of fossils collected by Mr. Eichardson from these coal-bearing 

 deposits was scarcely sufficient to establish the exact geological hori- 

 zon of the latter. 



Six years later a much more extended geological and geographical 

 exploration of the Queen Charlotte Islands was made by Dr. Gr. M. 

 Dawson, who has since published a detailed account of the results of 

 his explorations and of the conclusions arrived at therefrom in the 

 " Report of Progress " of the Canadian Survey for 1878-79, to which 

 the reader is referred for the fullest and latest information on the 

 subject. 



The following tabular view of the formations which have been 

 recognized in these islands, in descending order, is condensed from 

 that given on page 48 B of the volume just cited, with some slight 

 additions and alterations suggested by Dr. Dawson.
