“In the western and southwestern parts of the state—at 
Arcadia, for example—there ?re layers of quartzite in the 
Potsdam sandstone which have a “maple sugar” color and ap¬ 
pearance. I have found arrowheads in these parts of the 
state which resemble the quartzite referred to, and I have 
been led to believe that these were the sources of much of the 
material from which they were made.” 
T. C. Chamberlin mentions that many boulders of bluish- 
gray flinty quartzite found in the eastern sections of the town¬ 
ship of Deerfield, Dane county, have evidently come from 
mounds of Archaean quartzite that rise through the St. Peters 
sandstone in Portland township, in Dodge county. Some of 
the Mosinee hills quartzite he reports as stained with yellow, 
translucent in thin pieces and very brittle (Geology of Wis¬ 
consin, vol. 2.) 
REMARKS. 
Associated with other aboriginal workshop refuse, on many 
as yet uninvestigated Wisconsin village and camp sites, chips, 
flakes and blanks of quartzite are to be found. At various 
places along the shores of Lake Buffalo, in Marquette county, 
such evidences and quartzite implements are reported to have 
been formerly quite abundant. Of the latter, one Montello 
collector is known to have possessed hundreds of examples. 
Publius V. Lawson of Menasha, the well known student 
of archaeology, in a recent letter says:—“I have found chips 
oi quartzite and cores or stock blocks from which implements 
had been or might have been made. Quartzite implements 
are found on the shore of Lake Winnebago at Brighton Beach, 
at Little Lake Butte des Morts at Winneconne, and in the 
township of Poygan, in Winnebago county. I have trian¬ 
gular points from Aztalan, the shell heaps of Little Butte des 
Morts, and from Bear lake, in Waupaca county.” 
An attempt is now being made by Wisconsin students to 
locate, in the Baraboo ranges and elsewhere, the quarry aites 
from which the raw material was obtained by the aborigines, 
and where it was probably “roughed out” into forms conve-
