from north to south, from the Cobequid Mountains to the Atlantic 

 coast, a distance of at least 78 miles. 



The accumulations of drift on the Atlantic coast have been largely 

 derived from every formation intervening. 



We have found that there is no difficulty in referring the 

 greater proportion of the boulders in the drift to an approximate 

 source. 



"We have also found that the transported material has been 

 deposited over the intervening surface as well as on the extreme 

 coast. 



The enquiry now comes by what means was the drift material 

 transported and distributed as we have found it. 



INFERENCES. 



1. — The collector of rock specimens who may not consider it 

 necessary that these be collected from the original rocks in situ, 

 can readily and easily be supplied from the boulders on the beaches, 

 or from the sections of drift described. 



2. — A better collection can be made in this way than by 

 exploring the Cobequid Mountains, as the rocks are there so much 

 obscured by forests. 



3. — The drift has added to our knowledge of the lithology of 

 the Cobequid Mountains by furnishing interesting specimens of 

 metamorphic rocks allied to the known rocks, but not yet found in 

 the mountains. 



4. — Ores of metals and economic minerals may be found in the 

 drift, far removed from their original position. This inference is of 

 importance in a practical point of view, e. g. the iron ores of the 

 Cobequid Mountains and the trap rocks.

 TRANSPORTATION. — COURSE. 



At the Cow Bay Red Head, are seen massive quartzite boulders 

 fallen from the drift and projecting from it ; similar boulders are 

 found at other Red Heads. These often have their sides strikingly 

 grooved and striated. There is no hesitation in associating the
