lation whatever one to another; 
and many other localities are 
quite as remarkable for the 
great number and size of their 
kettle-holes. Often when two 
of these depressions are near 
each other the highest border 
of each is between them an 
their outlets in opposite direc- 
tions. And again it is often 
found that the esi 304 of the 
outlet is even as high as 30°, 
which would preclude the idea 
of flowing waters making them; 
for it would be very difficult 
to secure such a flow of waters
