V. GLACIAL SUCCESSION IN CENTRAL LUNENBURG. BY W. H. 

 PREST, Chester Basin, N. S. 



(Read llth May, 1896.) 



While prospecting for gold bearing veins during the past two 

 years, my attention was called to the opportunities thus given 

 to study the glacial geology of the district worked in. The 

 following observations and deductions are chiefly the results 

 of work done in the district between Bridgewater and Mahone 

 Bay, during parts of the years 1895 and 1896. My study of 

 this district is not in any way thorough, but consists merely of 

 occasional observations and their resulting conclusions. Know- 

 ing the great difficulty of correlating distinct and distant 

 deposits, I approach the subject w^ith trepidation, but, notwith- 

 standing, trust that the facts given may be of some service to 

 future investigators. 



PHYSICAL FEATURES. 



The general physical features of this part of Nova Scotia 

 are those of a gradual slope from the central watershed to the 

 Atlantic coast. This watershed, the South Mountain, averages 

 probably 700 feet in height, and is about 45 miles from the 

 Atlantic, which gives the very gentle descent of 1 foot in 340. 

 Its surface is diversified by morrainic accumulations which reach 

 a considerable development near the coast at Lunenburg. The 

 more local features are those of a low table-land, bounded on the 

 south-west by the valley of the Lahave, on the north-east by 

 the Mush-a-mush valley and Mahone Bay, and on the south-east 

 by the Atlantic Ocean. Its northern end is a continuation of 

 the higher land of the interior. In the central parts of this 

 table-land are the shallow subsidiary basins of Rhodenizer's and 

 Cantiloup's Lakes. At Blockhouse, in the eastern part of this area, 

 the surface is undulated by morraines and intervening swamps 

 and valleys. Here in a shallow valley, running about S. 50 E., 

 a large part of my work was done, and observations made. The
