SANDUSKY Bay AND CEDAR POINT DIZ 
was found broken and among timbers at or near the Carrying 
Ground. This was Bottle No. 37A, dropped half way between 
Sandusky and the west end of Johnson’s Island at I P. M., Sept. 
26, 1902, and carried by the current into the lake and cast ashore 
nearly 3 miles from the lighthouse, where it was found the next 
morning at nine o’clock. Bottle 42A set adrift at the entrance 
to the bay went ashore on the lake side of Cedar Point about half 
mile from the lighthouse. Both of these must have gone out 
beyond the end of the jetty. A number of my bottles were 
dashed to pieces on the jetty. After Mr. Anthony told me of his 
observation, I had a bottle thrown in the lake beyond the end of 
the jetty; Captain Magle reported that he threw it near the can 
buoy. This was about 3 p. m., Dec. 3, 1904. Dec. 6, at 8:30 
A. M., aman who had crossed the bay on the recently formed ice 
found the bottle on the lake beach more than two miles from the 
lighthouse. 
Part of the sand brought ashore by such a current may have 
come originally from the vicinity of Huron, having travelled the 
whole length of the beach, in and out of the bay a number of 
times and then ashore on Cedar Point again some where between 
the Carrying Ground and lighthouse perhaps to be pushed along 
to the end again and go the rounds once more. It would be 
interesting to know how many times some of the grains have 
taken such a journey. Another part of the sand which is swept 
out of the bay originated at Marblehead. This of course becomes 
mingled with that from the southeast. 
The wider beach along this part of the peninsula gives the 
wind more opportunity to take up sand, while its fineness caused 
by long attrition favors its transportation by the wind. 
RIDGE SECTION OF CEDAR POINT. 
This is the terminal portion of the peninsula, extending from 
the end to Biemiller’s Cove, about one mile. Its maximum 
width is over half a mile when the water is low but less when it 
is high. It is made up of parallel ridges which have been built 
up by the lake and consist of beach gravel and sand. It contains 
no clay or rock near the surface. At the power house clay was 
found about 23 feet below lake level and rock 46 feet below. 
Farther north both are probably deeper still. 
In crossing this part of Cedar Point not very near either end 
eight ridges are easily distinguished. Towards the end, espe- 
cially the south end, are others which do not extend so far. These 
eight ridges I have numbered beginning on the bay side. In 
describing them, however, I will begin with the most recent.
