+ F. Leverett— Correlation of New York 
present shore of Lake Erie and may be seen at numerous points 
from the railway lines which follow the lake shore from Buf- 
falo to Cleveland, as may also a lower beach (the Crittenden). 
Westward from Cleveland its identification is not made entirely 
certain. At the time of the preparation of the paper’ on the 
correlation of moraines with the beaches of the western part of 
the Lake Erie basin, it was the writer’s opinion that the Leipsic 
and Belmore beaches, which had been traced eastward to the 
Cuyahoga valley, each connected with a correlative moraine in 
the vicinity of that valley. Nothing has been found to com- 
pletely set aside this view, but upon further reflection an alter- 
native view has presented itself, viz: that the upper, or Leipsie, 
beach may be the correlative of both the moraines and that the 
Belmore beach may find its eastward continuation in what is 
here called the Sheridan beach. I take occasion, therefore, at 
this point, to set forth the situation more fully than was done 
in the earlier paper. In my former paper the statement is 
made (p. 298) that I have learned through correspondence with 
Mr. Gilbert that neither the Leipsic nor Belmore beaches con- 
tinue east from Cleveland. We have since that time conferred 
more fully on this matter and find that his data do not seriously 
conflict with this alternative view, as will appear in the table 
of altitudes of the Sheridan beach given below. 
For a few miles east from the mouth of the Cuyahoga it is 
difficult to identify the upper beach, there being a bluff-like 
rocky escarpment along the south shore of Lake Erie thinly 
clad with drift and rising to a considerable height above that 
of the beaches. On this escarpment several shelves appear. 
These shelves are of varying width from a few feet up-to 80 
rods or more. They are probably due to a combination of 
agencies embracing differential degradation in preglacial time, 
moulding by the ice-sheet, and wave action. The extent and 
influence of wave action was not fully and satisfactorily worked 
out. It is certain, however, that but a small portion of the 
cutting can be due to wave action, some of the shelves being 
much too broad to be formed by this agency alone in the not 
lengthy interval necessary to the formation of the beach. A 
few miles east from Cleveland the slope of the escarpment 
becomes less abrupt, and drift deposits of considerable depth 
occur, upon which the waves have left distinct traces. 
In the southwest part of Cleveland the Belmore beach stands 
about 170 feet above the lake. Passing east to the nearest 
point where the beaches are well developed, a short distance 
east from the city limits of Cleveland, we find that the upper- 
most beach (which is here called the Sheridan) stands only 
about 160 feet above the lake. Above this level the topog- 
raphy is morainie, and so far as the writer could detect it pre-
