I/innioi Helics in tlm J)rlft of Ohio. — ('hMjpoJc. 311 
During a recent visit to Cambridge, Prof. Putnam drew my 
attention to two or tliree implements in the Peabody Museum, 
wliich had been recalled to his mind by a sight of Mr. Mas- 
terman's axe. They are not grooved axes, but large celts 
made of shaly sandstone, which have obvioiisl}^ like the axe, 
been weathered since they were shaped, and if an inference 
from their lightness is allowable they must be weathered 
throughout. L^nfortunately their history is not known. They 
were found in Tennessee and on the surface, probably 
ploughed up.. They are in precisely the same cf)ndition as are 
thousands of pebbles of the same material in the drift gravels 
of Ohio. Both are oxydized completely through. 
No evidence can be drawn from these specimens in regard 
to the axe except in one point. The resemblance between 
them and the oxydized pebbles of the drift maj' mean that 
both have been equall}^ exposed. And as the pebbles are as- 
suredly of glacial date we can only on that view infer an equal 
age for the weapons. 
Other Speci Aliens. 
So far I have confined ray statement to the grooved stone 
axe in order that no confusion may arise on the subject. But 
Mr. Masterman has several other implements which should be 
at least mentioned. The argument for the axe must stand or 
fall on its merits. It is the strongest instance of all and yet 
ma}- gain some additional value from the others. 
Among these is a greenstone celt, found five feet deej) in the 
clay in digging a county ditch in. 1889. This is within the 
sulphur-water region and shows slight traces of solvent ac- 
tion, the feldspathic (albitic) portion being decomposed to a 
small depth. Other celts of greenstone from diiferent places 
where this water does not prevail show no traces of similar 
action. The finder of this was Mr. E. E. Masterman. 
Another specimen is a grooved axe of greenstone found in 
1S82 seven feet deep in the gravel. This also shows traces of 
chemical action and lay in the region of the sulphur watei-. 
It was found b}' E. Morris and given to Mr. Masterman. 
A third is a very rough and unfinished celt of slate showing 
a chipped surface over the greater part and traces of grinding 
only in a few places. It is, however, uncjuestionably of human 
make, and not lying in the region (if the sulphur water shows
