286 F. Lever ett — Correlation of Moraines 



Benton Ridge, Webster, Pandora, Columbus Grove, Alnora, 

 Delphos, Middlepoint and Van Wert, Ohio, and through Zulu 

 P. O., Indiana, to the outlet at New Haven. The north shore, 

 according to Mr. Gilbert's tracing, leads northeast from New 

 Haven, Indiana, and passes just west of Hicksville and Bryan, 

 Ohio. Dr. J. W. Spencer identifies it in Michigan at Adrian, 

 Tpsilanti and Berville.* It is not improbable, however, that 

 this beach terminates before reaching Ypsilanti and if so cor- 

 relation should be made there with the second beach. 



Mr. Gilbert's estimate of the height of this beach is based 

 upon its altitude where crossed by the L. S. & M. S. R. R. 

 near Bryan,f where it is about 220 feet. The altitude is 

 slightly lower along the south shore than at Bryan, as shown 

 by several independent railway surveys. It is evident, how- 

 ever, from the variations displayed by these surveys that ac- 

 curate leveling and a critical study of the beach with reference 

 to its usual stage of water will be required, before any conclu- 

 sions can be drawn as to differential crust movement between 

 Findlay and Fort Wayne. The beach here apparently stands 

 about 210 feet above Lake Erie. In the table given below, 

 the lower altitudes are slightly below the usual stage of water. 

 In Michigan there is, according to Dr. Spencer, a marked 

 northward differential uplift between Tpsilanti and Berville.

The Yan Wert ridge so far as I have examined it consists 

 in the main of a deposit of sandy gravel though for consider- 

 able distances it presents only a wave-cut bench free from 

 gravels. It is not a strong bench, its usual height being 3-5 

 feet and its breadth but 10-12 rods. Occasionally, however,
