IN NOVA SCOTIA ELLS. 445 



accompanied by a map of the area, was prepared and published 

 in the annual volume of the Geological Survey for 1896. in which 

 the leading geological formations were outlined and many import- 

 ant facts relating to the structure and mineral resources were 

 given. The detailed mapping of portions of this district is still 

 in progress, in order that the map-sheets of that portion of the 

 province may conform with those already published of the 

 northern and eastern divisions. 



Valuable papers have also appeared from time to time from 

 the pen of Mr. H. S. Poole, for many years connected with 

 important mining operations in the Pictou coal-fields, which 

 afforded him excellent opportunities for the study of the rocks 

 of the Carboniferous system, and also from Dr. E. Gil pin, of the 

 Department of Mines, Halifax, who has ably dealt with certain 

 points of structure presented by the rocks of that district, and 

 also with many questions relating to the occurrence of economic 

 minerals at many points throughout the province. 



In connection with Acadia College, Professor Haycock has 

 recently published two valuable papers, dealing largely with the 

 question of local geology, which are of much interest. In the 

 area about Wolfville and along the Gaspereau Valley, as well as 

 in connection with the rocks of the North Mountain range, 

 there is a most interesting field for investigation which has been 

 as yet scarcely touched. It is to be hoped that this area will 

 now receive that attention from local geologists which it well 

 deserves. 



In a paper of this kind it is, of course, very evident that 

 many points of great interest must be omitted. The merest 

 outlines of the subject have of necessity been stated, and there 

 are other names which have been associated to a greater or less 

 extent with the work of investigation, to which but slight 

 reference can be made. Among those who have thus contributed 

 papers relating to the geological structure and mineral resources 

 of the province at a comparatively early date, may be mentioned 

 by Mr. J. Campbell of Halifax, whose reports on the gold-fields, 

 in 1863 are of much interest, and Dr. H. Y. Hind of Windsor,
