has a height of from 40 to 50 feet above the sea. It is beef 
the deposits, (and 20 to 25 above the present sea level,) there is 
an abrupt change in the direction of the oblique lamination, the 
layers above this level rising to the south instead of to the north. 
Here is proof that a river flood had then set in that controlled 
the depositions in spite of the force of the incoming tidal currents. 
That the waters of this flood came loaded with sand and gravel 
iN enormous quantities is indicated by the thickness of the 
obliquely laminated layers; that there were plunging waves 1n 
the estuary connected with both the incoming tide and the flood, 
1s made manifest by the composite character of these layers. 
XI. In the Glacial era, the land over the higher latitudes 
Probably stood above its present level. 
TI € occurrence of fiords, both in the northern and southern 
hemispheres, in the Glacial latitudes, is favorable to this view, as 
I have elsewhere stated. For they show at least that during 
their formation the land in these latitudes was elevated above 
the present water level, when more to the south it was not so;
