it appears as if large masses of the clay portion of the till had been 
forced down into the sands. In others the till has been laid upon the 
sands with very little disturbance. An uncomformable contact between 
the massive portion of this till sheet and the little disturbed underlying 
sands is particularly well shown near Section 4, half a mile east of Port 
Granby. 
CORRELATION WITH THE SCARBORO SECTION. 
Until the intervening section, forty miles in length, between that 
described here and the Scarboro section, has been studied in detail, an 
adequate correlation of the deposits in the two different localities is im- 
possible. The lowest till sheet in the section here described, which has 
been shown to be persistent along the shore, with very slight interrup- 
tions for the forty miles, is probably the equivalent of one of the sheets 
in the Scarboro section. The absence of fossils in the interglacial 
deposits of the Clarke section makes it at present impossible to correlate 
these deposits with the interglacial deposits at Scarboro. Dr. A. P. 
Coleman regards it as quite probable that the lowest till sheet in the 
Scarboro section has no equivalent representative east of that section. 
The lowest till sheet of the Clarke section and eastward, he considers 
as the probable equivalent of the second till sheet at Scarboro, and the 
stratified non-fossiliferous beds immediately above this sheet would 
then be the equivalents of some of the upper series in the Scarboro 
section. 
In the study of the Scarboro section it was also found that an erosion 
interval of considerable duration preceded the deposition of the second 
till sheet. In the section here studied in detail it is found that a pro- 
longed erosion interval followed the deposition of the second interglacial 
deposits of the locality. It is quite possible that the sheet of till desig- 
nated the second till sheet in this paper, may not be contemporaneous 
with any of the till sheets of the Scarboro section, but may merely mark 
an episode in the general retreat of the ice sheet previous to the deposi- 
tion of the interglacial beds here regarded as of the second interglacial 
epoch. It would then be similar to the two intermediate till sheets 
designated A and B above, and would mark a somewhat larger trans- 
gression of the ice sheet. The evidence at present in hand is not 
sufficient to warrant a correlation of the deposits in the two localities 
on the assumption that these erosion intervals are contemporaneous and 
not successive ; but, on the other hand, it may be noted that the occur- 
rence of what may be three local sheets of till, separated by stratified
