162 GLACIAL SUCCESSION IN CENTRAL LUNENBURG—PREST. 
It shows no sign of stratification, and contains large numbers of 
striated boulders. 
A few boulders with the striations almost effaced are found 
in 2, a, and striated boulders are also found in the surface soil, 
3. Oxidization is most complete in the lowest bed, 1, which is 
of great thickness, while the upper bed is the least oxidized of 
all. This is only part of a larger kame which has suffered 
extensive denudation on the western side. 
At Bridgewater it is impossible to get a good section, but 
near the railway station and at Sebastopol the beds show the 
following arrangement : 
7, Recent alluvium, with tree trunks and stumps, and ancient 
Indian implements, overspread by forest growth. 
6, Modified drift and river gravels. 
2 to 5, Succession uncertain. Deposit consist of boulder 
clay, kames, and river terraces; the kames being very highly 
oxidized and consisting of the same material as the underlying 
oxidized drift. 
1, The sc-called Bridgewater conglomerate,—a pasty iron 
cemented mass of rounded and angular boulders of quartzite, 
slate, granite, trapand diorite. This is the most highly oxidized 
deposit in this part of the province, and contains striated rocks. 
It is slightly modified in its upper portions, but is underlaid by 
completely oxidized local drift, consisting of angular fragments 
of slate in a matrix of clay and sand. 
CORRELATION OF DEPOSITS. 
First Glacial Epoch. 
The Bridgewater drift conglomerate is evidently the most 
ancient glacial deposit in this part of Nova Scotia. The evidence 
for this is as follows :— 
Ist. It is always seen in direct contact with the bed rock 
and cemented thereto, so as to become in its lower portions — 
almost immovable without the aid of dynamite.
