above lake level; but the base of the cliff is so obscured that this 
could not be proven. It reappears along the shore in several places 
west of Section 8, but as a rule the exact height of the upper surface 
above lake level could not be ascertained until within a quarter of a 
mile east of Section 13, where it is five feet. The height increases 
rapidly to thirty-two feet above lake level at Section 13. From here 
it gradually descends towards the west, passing below lake level west 
of Section 15. 
Midway between Sections Io and 11, three miles east of Newcastle,

In this section it will be noted that there are four beds of till exposed 
above the laminated clays which in several sections along the shore are 
found to overlie the lowest till sheet. The two intermediate sheets (A 
and B above) appear here between what have been termed the first and 
second sheets. The lowest of. these sheets, A, has a thickness of five 
feet. It was not found in other sections on either side, and it is quite 
certain that its length in the cross section exposed along the lake shore 
is only a little over half a mile. It is probable that it reaches as far 
west as Section II, but it could not be located on account of the talus 
cover. The next till sheet above this, B of the section, has a thickness 
of eleven feet. It also occurs in Section 11 with the same thickness. 
It is uncertain whether it is present in Section 10 or not. If so it does 
not extend much to the east of that section, and its total length in 
cross section is a little over one mile. 
The uppermost or third till sheet is exposed continuously along the 
whole length of the Clarke section.
