Introduction. 



This paper represents the results of a brief geological re- 

 connoissance along the shore of Southwestern Nova Scotia 

 from Jordan Bay to Barrington Passage, made during June 

 1913. The object of this reconnoissance was to study the 

 structural geology, but outcrops were found to be few in 

 number, and to be practically confined to the wave-beaten 

 ends of the peninsulas, and therefore the work was not ex- 

 tended farther. As the only detailed previous examination 

 of the region was made by Dr. L. W. Bailey in 1891 to 1896*, 

 it is thought that this paper may form a contribution to the 

 knowledge of the region. The structural details and the 

 petrography of the igneous rocks were not considered in Dr. 

 Bailey's report. 



The general geologic features of the region consist in a series 

 of pre-Cambrian metamorphic quartzites and schists intruded 

 by Devonian granites which have produced extensive con- 

 tact metamorphism in the already regionally metamorphosed 

 and folded sediments. Glacial deposits now cover the sur- 

 face allowing the geologist only an occasional glimpse at bed 

 rock.
