212 Notes on the Drift and Alluvium of Ohio and the West. 
ahoga River in Summit county, Ohio, the blocks of buff colored 
limestone are so numerous as to be gathered and burnt for lime. 
There was one in the township of Bath in that county, as large 
as a small house, whose parent bed was evidently near the islands 
of Lake Erie, sixty miles northwest. 
On the hills a few miles west, and also north of Fulton in 
Stark county, Ohio, on the Ohio canal, granitic and greenstone 
boulders may be seen, ten and twelve feet through, and six hun- ~ 
.dred feet above the lake. They are almost as heavy as the larg- 
est trap boulders of Lake Superior, which have been transported 
only a few miles from their original resting place. The inference 
is therefore strong, that whatever may have been the kind of 
force employed in their transportation, it continued in equal inten- 
sity, till they were dropped several hundred miles from the point 
of departure. 
Primitive boulders are not found to my knowledge, in the blue 
marl of Lake Erie, nor in the “blue hard pan.” I think they 
are not found in the “ yellow hard pan,” and only occasionally 
in the “sand and gravel drift,” not more often than blocks of 
conglomerate Waverly sandstone, or the grits of the coal series. 
They have been rarely seen in the member, No. 2, of formation 
No. 5. They are found upon the lacustrine deposits, but by no 
means as numerous as on the upland drift. It is for this reason 
that I venture to call the boulder deposit here a “stratum,” and 
the newest of all beds except the alluvium. 
ur superficial deposits differ distinctly, in this respect, from 
those of the St. Lawrence, New York and New England, and 
also in the want of fossil shells. Mr. Lyell, Prof. Hitchcock, Dr. 
re mingled with the dadsiviaess 
all sizes. 
I shall soon notice another material distinction in the observed 
reliquie of the eastern and southern deposits, compared with 
the western, that is, in the remains of animals. 
If my observations are correct, the boulder is more recent than 
the lacustrine deposits of Lake Erie as well as the diluvial beds 
of the uplands, lying as it does above and upon them all. 
Buried Timber —In 1844, while making a cursory survey of 
Hamilton county, Ohio, in reference to agriculture, I examined 
fifty-nine wells in different parts of the county, and of these six, 
or about ten per cent., had “dirt beds,” leaves, timber, or “ silt.” 
They were situated at an elevation of three hundred to six hun- 
dred feet above the Ohio River at Cincinnati, which at low wa- 
ter is one hundred and thirty-three feet below the lake surface. 
As this is a subject I have not seen noticed, I shall give some 
details of the timber here and in other parts of the state.
