GLACIAL SUCCESSION IN CENTRAL LUNENBURG PREST. 159 



height above the sea level is probably about 135 feet. The 

 Lahave occupies a narrow pre-glacial valley, reaching 20 to 30 

 feet below high tide, and flowing amid picturesque hills about 

 200 feet high. The Rhodenizer Lake basin drains the highest 

 part of the table-land and flows S. S. W. between morraines and 

 kames until it reaches the estuary of the Lahave. The central 

 part of this basin, at Blysteinner Lake, is 183 feet above mean 

 tide level, while Rhodenizer's Lake is 160 feet. The Cantiloup 

 Lake basin drains the southern part of the tract under discus- 

 sion, and is occupied and surrounded by morraines which have 

 in some cases diverted the streams from their pre-glacial courses. 

 At Dorey's Brook, in this basin, work was done which disclosed 

 several facts bearing on the glacial succession in this district. 

 I will now give a few sections which represent fairly the major- 

 ity of those recorded by me. They are numbered to correspond 

 with the glacial or inter-glacial epoch in which they are sup- 

 posed to have originated. (See page 164.) 



DESCRIPTION OF DEPOSITS. 



Blockhouse. The sections set down below are copied from a 

 record kept on the spot, and taken down as the work of trench- 

 ing and sinking proceeded. As those pits are sunk quite close 

 to each other, the correlation of the deposits in this locality was 

 not a very difficult matter. The sections of course differ as the 

 position and depth of the pits showing them' differed, but the 

 corresponding layers in each section will be numbered alike 

 regardless of their distance from top to bottom. The absence or 

 presence of auriferous quartz in the upper layer was owing to 

 its position in regard to the lead. If on the lead, the lower layer 

 contained the gold-bearing quartz ; but if to the south-east, then 

 the upper layer contained it. 



Section 1, beginning at the top, 13 feet deep. 



5, Clay and rocks, mostly local and much oxidized. 



4, Sioris of denudation. 



' O 



3, Dark coloured boulder clay, including granite, quartzite, 

 and other northern drift.
