Human Relics in the Drift of Ohio. — (Jiaiipole. 1^09 
At the well nearly all the material passed through was clay 
becoming tougher and tougher downward and resembling the 
tine silt that settles from still water. The axe must have 
been deposited there when the thin gravel bed in which it was 
found was formed, as it lay directly upon the boulder-clay. 
If there is no other origin or date for the fine clay and streaks 
of sand that overlie it than that which assigns them to late 
glacial time then the tool must be set down to the same epoch 
and must be considered the work of glacial man. 
There is no ground in the present instance for the objection 
that has been urged with much force in some similar case? — 
that the ground has been disturbed and that the implement is 
of later introduction. The well from which it came is situ- 
ated in the wide plain already described. No river channel or 
(juarry-face exists within a long distance. Buck creek, the 
nearest stream, is three miles to the south, and that excepted 
there is no break in the continuity of the surface and very 
little variation of level anywhere. The thin streaks of sand 
in the clay absolutelj'^ preclude any supposition that the 
ground had been previously disturbed, while the great depth 
(22 feet) and the nature of the soil passed through exclude 
all other theories that have been advanced in similar cases to 
account for the presence of implements in glacial gravels, 
such as falling into cracks, rotten root holes, etc. 
The section as here given, moreover, is not dependent on 
memory, for on my pointing out the importance of accuracy 
and certainty in the evidence, Mr. Masterman ottered to ver- 
ify his statement by boring down alongside of the well. This 
he did nearly to the full dejath and the only result was en- 
tirely to confirm his previous account. 
Probable Cause of the Weathered Condition of the Axe. 
I have already referred to the condition of the axe and this 
topic now calls for further notice. It was at first very puzzling, 
as such objects are not usually weathered to any appreciable 
extent even when lying on the surface. To find this one com- 
pletely leached or oxydized throughout was therefore not a 
little surprising and I began to enquire into the circumstances 
in which it had been lying. The first point for investigation 
was the quality of the water and on enquiry I soon learned, 
as I had suspected, thas it was sulphureous. Further exami-
