The following determinations were made by Mr. Holmes: 
Section 4, N. E. 623.3, 625.8. 
“ 33 , S. E. 600.9-613.3 and 625.3. Apparently two 
beach formations. 
Section 6, N. E. 625.3, top. 
“ 10, S. E. i, 626.3, “ 
In Tittabawassee, T 13 N., R 3 E. and along the river road in Section 
17, there is a beach having an elevation of 622 feet A. T. at the top. 
Thence south and east again into the tier of townships next adjoining is 
found in Section 6 of Maple Grove, T 9 N., R 4 E., and northeast of the cen- 
ter, a beach at an elevation of 616 feet A. T. at the top. 
In the S. W. \ of Section 6, T 11 N., R 4 E. is found a beach formation 
comparable to the one in Section 33, Thomastown having a height of 613.3 
feet A. T. at the top. and probably referable to the lower Algonquin beach 
formation. 
In Taymouth, T. 10 N., R. 5 E. we have: 
Section 21, east line, 624, top. 
“ 24, “ “ 627. 
“ 18, west “ 626. 
There is also another set of beaches with an elevation at the top of from 
611-615' A. T. Mr. Holmes gives beach determinations in this township 
as follows: 
Section 4, north, 4, 614.3-615.8, top. 
“ 4, S. E. I, 616.8.

“ 10, N. W. T 620.3. 
“ 12, N. E. 625.3. 
In Bridgeport, T. 11 X., R. 5 E. there is again suggested a slightly developed 
beach, lower than the highest Algonquin beach in Bay county, and higher 
in elevation than the normal altitude of the main lower beach of that area. 
This intermediate beach is also fairly well defined in the area under 
consideration.

Coming down to the lower Algonquin beach which has in Bay county an 
elevation of from 593-610 feet A. T., bottom and top, the following obser- 
vations are available in Brant, T. 10 N., R. 2 E.

In Fremont, T 11 N., R 2 E. we again get a beach intermediate in height 
between the lower and upper beaches on the north side of Section 1 at an
