TENTH REPORT. 
In this connection it is necessary to state that Mr. A. C. Lane did the field 
work in R. 4 E., Tp’s. 10-13 N., R. 5 E., Tp’s. 12, 13 N., and a portion of T. 
10 N., and all of T. 12 N. This includes much of the lower areas of Saginaw 
county and consequently a very considerable portion of the Lake Nipissing 
history which is only partially included in this account. The different 
beach formations will be designated by their elevation above sea level, or 
above tide (A. T.) and I have attempted to classify them according to that 
base. 
702-715 foot beach. 
This beach is well developed in the southern part of Saginaw county near 
the county line in T. 9 N., R’s 1, 2 E., and the elevation as determined by 
Mr. Holmes in the S. W. ^ of Sec. 34, T. 9 N., R. 1 E. was from 702.8 up to 
714.8 and 714.9 A. T. In Brady, T. 9 N., R. 2 E., the following elevations 
were obtained with the aneroid and level. 
Section 31, east line, 715 A. T. 
“ 33, north “ 716 A. T. 
“ 35, “ “ 720 A. T. 
“ 31, N. E. i 715.9 at top. 
In Mt. Forest township, Bay county, T. 17 N., R. 3 E., there is a well de- 
veloped beach at an elevation of from 720-734 with which this may corre- 
spond. Whether this is one of the Upper Grassmere or Lower Forest Beaches 
has not been determined. This may be one of the beaches noted by Mr. 
Lane in his Huron county report from 729 foot up. 
680 foot beach. 
In Lane’s Huron county report we have the bottom of the Grassmere 
beaches given an elevation of 680 feet A. T. In Bay county there is a well 
developed beach near Mt. Forest station having a height of from 675-690 
A. T., bottom and top. In Saginaw county and on the north line of Section 
22, T. 9 N., R. IE., we find a former shore line 683 ft. A. T. at the top. In 
T. 11 N., R. 1 E. we have the following readings. 
Section 9, S. E. 684.8 at top. 
“ 10, S. E. 1,684.3 “ “ 
“ 9, N. E. J, 686.8, 687.3. 
“ 9, S. W. i, 687.3 top. 
“ 5, T. 11 N., R. 2 E., 683 at top. 
651-665 foot beach. 
With the next halt in the lowering of the lake level is found a well de- 
veloped beach in the western and southern part of Saginaw county. In 
Chapin, T. 9 N., R. 1 E. the following determinations were made. 
Section 4, N. E. corner, 651.5-664.7, bottom and top.
