More SpEcIAL ACCOUNT OF THE GLACIAL MARGIN. 
Through Columbiana county, as in the adjoining counties of Penn- 
sylvania, south of the heavy deposits of till, there is a fringe from one 
to three miles wide, over which there are scattered evidences of glacial 
action, consisting of granitic boulders and patches of till, here and there 
upon the highlands, at an elevation of from three hundred to five hun- 
dred feet above the Ohio river. North of this fringe the till is con- 
tinuous and everywhere of great depth. At Palestine, on the eastern 
edge of the county, and at New Alexandria, near the western side, wells 
are reported in the till fifty feet deep. New Alexandria is upon the 
highest land in.that part of the country, and the glacial deposits are 
marked in moderate degree by the knobs and kettle-holes characteristic 
of the moraine upon the south shore of New England. A mile or two 
west of Canton, in Stark county, the accumulations of glaciated material 
are upon a scale equal to anything upon Cape Cod. The northern part 
of Holmes county is covered with till, which is everywhere of great 
depth, and in numerous places near the margin, displays, though in a 
moderate degree, the familiar inequalities of the New England moraine. 
After the southern deflection, in Knox county, the glaciated region is 
entered near Danville, from the east, on the Columbus, Mount Vernon 
and.Akron Railroad, through a cut in till, a quarter of a mile long, and 
from thirty to forty feet in depth. At the old village of Danville, near 
by, upon a neighboring hill, wells are reported as descending more than
