five inches in diameter, comes from Waupaca county. A 
smaller disc of a grayish color is in the Logan museum. The 
locality is Whitestovm, Vernon county. 
Several quartzite celts or hatchets, from Cedarburg and 
Boltonville, are in the Ellsworth collection, now in Beloit col¬ 
lege. Their surfaces are roughly chipped. The largest meas¬ 
ures about 4% inches in length. The existence of several 
quartzite hammers or club-heads has been reported, but none 
of these have been examined by the writer. 
Discoidals or “tchunkee” stones of this material are occa¬ 
sionally obtained from local village sites. These are very 
symmetrical in form and smoothly polished. A fine speci¬ 
men in the Benedict collection, of a light brownish color, 
measures 3 y 2 inches across its face and one inch in thickness. 
The depressions on either face are of a nearly uniform depth 
of % inch and extend to within about inch of the circum¬ 
ference, leaving a narrow rim. A somewhat smaller speci¬ 
men of the same type, from the township of Moundville in 
Columbia county, is in the Logan museum. In the S. D. 
Mitchell collection at Green Lake is another fine example. 
Excelling all of these in point of excellence of workmanship, 
is a discoidal now deposited in Milwaukee-Downer college by 
the Wisconsin Archaeological Society. This specimen is prob¬ 
ably the one described and figured in Lapham’s “Antiqui¬ 
ties of Wisconsin” (Fig. 58), although the illustration given 
of it there is poor. It measures about 3% inches across the 
face of the disc and 1% inches in thickness. The cups are 
conical and connected at their apices, thus giving a perfora¬ 
tion through the center. This is the only quartzite discoidal 
known to the author, which possesses this feature. It was 
found at Milwaukee. The material is of a light brownish 
color.
