ice must have passed over a granitic country in which the 
felspathic constituents of the rock greatly preponderated, 
and the kaolinised features of the clay on some parts of this 
coast may be caused by the waste produced by such a fel- 
spathic bed rock. 
The beach in front of this line of outcrop is strewn with 
erratics of all sizes—quartzites and granites being in greatest
