iil tVoin iirrow-lieads by tlicir size. 
AlTpoints over two and one-foiirtli in- 
ehes long (unless very liglit) are ad¬ 
mitted to be spear heads. Spear heads 
often reach seven or eight inches in 
length, blit ones longer are iiiiite rare. 
Lance heads and spear heads are often 
confused; indeed it is very hard in 
some cases to tell one from the other. 
Hut the following rule will greatly 
help one: “Lance heads are usually 
leaf shaped, thin and delicately chip¬ 
ped and quite sharp.'” 
Flint knives occur less frequently 
than the implements just mentioned. 
Knifes, as a rule, are better made. 
They vary in length from one and a 
half to six inches. Some of them 
have the point chipped to a beautiful 
curve and are quite sharp. Others 
are high in the centre and slope to the 
sides. Most of them were made to 
use without a handle. Flint scrapers 
are rare in some localities. In central 
Ohio they occur in large numbers. It 
is supposed that these scrapers were 
once good arrowheads, but becoming 
broken, were chipped down to a broad 
edge, lashed to a stick and used to 
scrape hides, scale lishes, etc. 
Drills are the most beautiful and 
symmetrical of all the flint implements. 
The material out of which they are 
made has to be of the best. The aver¬ 
age length of drills is three inches. 
Some few have been found nearly five, 
the perforations in the slate ornaments 
were probably made with these drills. 
Gun flints are often found. The}^ 
can hardly be classed as implements, 
and a word will be suflicient to explain 
them. The}^ were used by the Indians 
on the old flint lock muskets. 
Discs, celts and spades are of similar 
forms, and hence, are very hard to 
classify correct!}'. Round flat pieces 
of flint roughly chii)ped are found on 
the surface and occasionally in mounds. 
For want of a better term they have 
been called discs. Celts made of flint 
with well worked edges occur in certain 
localities. They bear a great resem¬ 
blance to spades. Spares are large, 
spear-head-shaped blocks of flint. 
They are found in numbers in Mis¬ 
souri and Illinois. It is supposed that 
they were employed in throwing up 
the mounds and in loosening the earth 
so it could be readily scraped into 
baskets and carried to the embank¬ 
ments.
