Sandusky Bay and Cedar Point 223: 



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., a man who had crossed the bay on the recently formied 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 probabh^ 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.
