V.—GLACIAL SUCCESSION IN CENTRAL LUNENBURG.—By W. H. 
Prest, Chester Basin, N. 8. 
(Read 11th 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 
oceasional observations and their resulting conclusions. Know- 
ing the great difficulty of correlating distinct and distant 
deposits, I approach the subject with 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 fromthe 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 8S. 50° E., 
a large part of my work was done, and observations made. The
