In the course of a geological survey of the south-western 

 counties of Nova Scotia, of which the results form the substance 

 of a report soon to be issued by the Geological Department at 

 Ottawa, several interesting questions in connection with the 

 rocks of the Annapolis Valley were brought to notice, but as to 

 which the data obtainable at the time were not sufficiently 

 complete to warrant definite conclusions. It was hoped that 

 opportunities for further study would be available, but as this, 

 so far as concerns the writer, does not now seem probable, he has 

 thought it well, in the following notes, to make brief reference 

 to the nature of these questions, that others interested in the 

 geology of this part of the Province, and more favorably situated 

 than he, may be able to give them further attention. 



It has been usual to regard all the rocks of the Annapolis 

 Valley, other than those which form its southern wall, as being 

 of Triassic age, and, further, as embracing a sedimentary and a 

 volcanic series of which the latter was altogether the more recent 

 and overlaid the former. A close examination of some sections 

 in the vicinity of Digby tend to modify the second at least of 

 these conclusions. 



The first section to which reference is made is to be found in 

 the parish of Granville, on the eastern side of Digby Gut. From 

 the point where the latter suddenly expands to form Annapolis 

 Basin, the shore, for nearly half a mile to the northward, shows 

 a series of low bluffs of a bright red colour, in connection with 

 which at some places may be seen ledges of very soft red shales. 

 In going northward along the Gut shore and approaching the 

 high trappean hill whose face has been laid bare by an extensive 

 land slide, similar red beds continue to show, but become some-
