These facts show a rather exceptional case of deformation. 
Taking the altitude of Cook's Mill and that back of Mar- 
quette, which is about 42 miles farther north, the northward 
rise of the highest shore line appears to be about ten and a 
half feet per mile. This is more than twice the rate which 
lias been established thus far at any locality. There is also 
a westward component of distance, amounting to about 4K 
miles, and considering that Lawson's highest beach at Sault 
8te. Marie is 1,014 feet above sea level, or about 175 feet low- 
er than that at Marquette, it seems likely that the highest 
beach has a westward component of elevation from Cook's 
Mill. 
The highest beach of Green bay shows one feature, which 
is the same as that described in a previous paper relating to 
the shore lines of the east coast of lake Michigan.* It was 
found there that from a point located at or near Petoskey 
southward the highest beach rises to the north at the rate of 
a little more than six inches per mile, but that from Petoskey 
northward to Mackinac island it rises at the rate of about 
three feet per mile, showing apparently a rather sudden change 
in its plane. From Mackinac to Sault Ste. Marie the north- 
ward rise is about four and one-third feet per mile, but it is 
not known that the change of rate is so abrupt. On the west 
coast the change of rate is not so great along the southern 
part, but it is much greater toward the north. The northward 
rise from Two Rivers to Birch (reek, in a northward distance 
of about 73 miles, is about eight inches to the mile, and the 
intermediate stations observed are very close to this plane. 
From Birch Creek to Burnt Bluff the northward component of 
distance is about 84 miles, and the northward rise about two 
feet and two inches per mile. From Burnt Bluff to Cooks 
Mill the northward component of distance is about 19 miles, 
making the northward rise about two feet and four inches per 
mile.
