8 F. Leverett—Correlation of New York 
Probable Oorrelative Moraines of the Sheridan Beach.— 
There are two morainic lines in southwestern New York, the 
date of whose formation is thought to have been contempo- 
raneous with that of the Sheridan beach. ‘The outer of these 
two morainic belts is well defined as far southwest as the Catta- 
raugus valley near Gowanda, about 15 miles east from Sheri- 
dan. Westward from Gowanda, along a line leading past 
Perrysburg, Nashville and Forestville, there is a bowlder belt 
which is now thought to mark the line of continuation of the 
ice margin. This has been traced westward only to the valley 
of Walnut creek near Forestville. At the time this bowlder 
belt was examined the well defined morainic belt leading north- 
east from Gowanda had not been observed, and it was supposed 
to be only an unusually bowldery inner border of the Dayton 
moraine, a moraine which hes immediately south of it. But 
upon examining the district east from Gowanda the well 
defined moraine alluded to was discovered and found to be 
distinct from the Dayton moraine and to be very thickly set 
with bowlders. These features suggested the possibility that 
the bowlder belt west from Gowanda should be distinctly 
separated from the Dayton moraine. With this.suggestion 
arose the query whether the belt may not be a correlative of 
the Sheridan beach. No opportunity came for revisiting the 
region and testing the value of these after thoughts by a care- 
ful study of the relations of the bowlder belts to the eastern 
terminus of the beach. It is certain that the bowlder belt does 
not continue with such strength beyond the valley of Canada- 
way creek unless it be inside (north of) the Sheridan beach, for 
the writer made a careful examination of the narrow district 
between the Dayton moraine and Sheridan beach for about 30 
miles westward from the creek valley, and at frequent inter- 
vals to the western terminus of that moraine 100 miles further 
west, near Cleveland, Ohio. In the 8-10 miles between Wal- 
nut creek and Canadaway creek, where we now suspect a con- 
nection between the moraine and beach to occur, no observa- 
tions were made. 
The position of the moraine is indicated on the accompanying 
map. At its eastern end it connects with the northern part of 
the great interlobate belt which occupies the ‘“ Watershed of 
Western New York.” The moraine, where well defined, has 
a breadth of 1-2 miles. The bowlder belt has about the same 
breadth. It is not a bulky moraine even where well defined, 
its usual relief being but 10-20 feet above the district south- 
east of it. A few knolls have a height of 30 feet, but the 
majority are 10-15 feet in height. They are, as a rule, closely 
aggregated and, together with the liberal supply of surface 
bowlders, they give a decidedly morainic cast to the belt and a
