are a number of places where the shore is formed by a barrier beach 
built by the waves, and the pleistocene deposits pass under the beach, 
no exposures being visible. Between these barrier beaches there are 
several places in which we find low cliffs, varying in height to a maxi- 
mum of about twenty-five feet. The deposits in which the cliffs are cut 
consist chiefly of a compact and, in places, arenaceous till carrying 
numerous pebbles, cobbles, and some boulders. Overlying the till sheet, 
which is of irregular thickness, is a deposit of fine textured stratified 
sands. In places the low cliff is cut wholly in the sands, the till pre- 
sumably being below water-level. In one locality the waves are now 
cutting into an old sand dune which must be of comparatively recent 
origin. About a mile and a-half west of Lakeport, at Ogden’s Point, 
bed rock is not exposed on the shore, but it can be seen off shore be- 
neath about six feet of water. The next exposure of rock occurs at 
Grafton point, about five miles west of Lakeport. At the point and for 
a short distance west of it the rock seems to be overlain by a deposit of 
stratified sand, though it is probable that there is a thin drift cover be- 
neath. Immediately to the east of Grafton pier there is a small exposure 
of white clay till, apparently the remnant of a drumlin, now almost com- 
pletely washed away by the waves. Commencing about a quarter of a 
mile east of the pier and extending for one and a-half miles is a cliff 
about thirty feet in height at its maximum, the upper part of which is 
formed by stratified sands. If the till occurs above lake level and be- 
neath these sands it is obscured by the talus from the cliff. Beyond this 
cliff, eastward, the shore is bordered by a barrier beach the gravel of 
which is probably derived from a till deposit underlying the sands of 
this cliff. Still further east similar sands again form a low cliff, giving 
place, near Ogden’s Point, to an arenaceous clay till, carrying numerous 
pebbles, cobbles, and some very large boulders and blocks. In places 
the till is overlain by thin deposits of sand. Just east of the point, and 
extending to Lakeport, the till forms a cliff about twenty feet in height. 
The surface rises rapidly inland to an elevation of about forty feet. Al- 
lowing for that which lies below water-level the total thickness must be 
about forty-five feet. 
West from Grafton Point the upper surface of the sands which form 
the low cliff at the point, gradually becomes lower so that the land 
slopes gently down to Jake-level. About three miles west of the point 
deposits of a compact argillaceous till again form a steep cliff with a 
maximum height of thirty feet, but gradually lowering both east and 
west. This till passes beneath the sands on either side of it. Continuing 
west along the shore the till gives place to sands. About three miles
