Review of Recent Geological Literature. 12-, 
the present coast line, advancing upon the land to a distance that varies 
from two to eight miles. Thus obstructed, the valleys and dales of 
this hilly district held many glacier lakes, as shown by the channels of 
their outflow over present lines of watershed. Lake Pickering, 24 miles 
long from east to west and 8 miles wide, was the most southern and the 
largest of these ice-dammed lakes; and lake Eskdale, joining Vvith the 
Kildale lake, in the northern edge of the district, was the second in 
size, measuring 10 miles in length. 
The author finds evidences of a long period of preglacial elevation 
of this region. During the continuation of that time the European ice- 
sheet, flowing outward from the Scandinavian peninsula, extended 
across the entire basin of the shallow North sea, then a land plain, 
bringing boulders and pebbles from Norway to the English coast.
