490 GEOLOGY OF OHIO. 
inches, breadth one and a half, and thickness five-sixteenth. Possibly it was a Phallus. 
A sixth piece is almost semi-circular, being about five inches by two and a half. It 
seems to be half of the original instrument, which must have had the form of an ancient 
doubl.-edged battle-ax. The break has been through the eye, which was bored very 
truly, the hole being about two inches long by half an inch in diameter. 
The other bored fragment is too small to warrant much conjecture as to its shape or 
use. 
All these pieces are of light-colored slates, but the remaining two are darker, and are 
of very peculiar shapes. 
One might be described as a Spanish saddle with the skirts cut off. It measures three 
and three-eighths inches by one and a half inches high. At each end a hole is bored 
through the lower edge, as if for crupper and holster strap. 
The other piece is not quite so stout, but the pommel has been extended forward, 
until it is as long as the body, and the end is turned downwards as if in rude imitation 
of.an animal’s head. The same holes ovcur as in the last piece. This piece measures 
four and three-quarter inches by two and a quarter. A cross section through any part 
of either of these ‘‘saddles” will resemble the diagram of a spherical equilateral triangle. 
These forms are not very uncommon in collections, although I have not found any sug- 
gestion as to their use or meaning. As many specimens have a raised circle on either 
side of the ‘‘head,” as if to represent eyes, the idea may have been derived from some 
animal. 
This collection must, by no means, be supposed to have exhausted Logan county. No 
doubt great numbers of the relics are still scatterea there, and were it generally known 
that you propose to keep the collection displayed by itself in the Agricultural College 
. museum, the number of specimens would be largely increased by donations. 
Respectfully,
