and pressing outwards towards the sea. This glacier cake must 
liave been slowly floated off by the gradual subsidence of the land. 
As it floated off the boulder-clay was deposited under the edge of 
the ice-foot on the freshly striated surface of the rock, protecting 
it at once from the action of the surf, consolidated under the pres- 
sure of the ice-cake, hut showing traces in its shells and its strati- 
fied layers of the presence of the sea. There on the surface of the 
rock the boulder-clay has rested throughout the long period during 
which the land subsided to a depth of 1500 or 1700 feet or more, 
and again re-emerged till it approached, under an ever softening 
climate and with a more temperate fauna, to almost its present level. 
In short, the 40-foot beach terrace owes its configuration not so 
much to the external action of the sea, as to the internal contour 
of the rock. That contour was derived from the grinding agency 
of the ice-cake covering, and between the period when that contour 
was given to it, and the presence of the sea at the 40-foot beach - 
line, there have intervened all the countless ages, with their mani- 
fold changes, of the subsidence and re-elevation of our land.
