alone. These are properly mound articles, thus far unknown in 
New York. He found there many articles of sheet copper, some- 
times stamped or ornamented, naturally suggesting recent 
material but clearly aboriginal. It is definitely known that — 
native copper was beaten thin enough for turning the edges 
under and overlaying prepared forms. Out of one of these mounds 
Mr Moorehead took a copper ax 22 inches long and 6 inches wide. 
This weighed nearly 38 pounds, not quite seven times as heavy 
as the largest New York implements of this kind.—Moorehead, 
p. 325 : 
Wisconsin naturally affords the greatest supply, being near the — 
ancient mines. Mr F. S. Perkins sold 143 local copper imple- — 
ments to the Wisconsin historical society, and in 1886 had 
another collection of over 600 exclusive of beads. The Hamilton 1 
collection is also notable, containing most New York forms, as — 
well as small fishhooks and unusual ornaments. The University — 
of Pennsylvania has 560 articles gathered from a space of 5 acres — 
in Wisconsin. The writer met with a curious Wisconsin collec- 
tion at Manitou Col. The articles were flat and symmetric, cut — 
from rolled or beaten copper and showing none of the irregulari- — 
ties of early implements. Some found at Brewerton N. Y. are — 
suggestive of these. Native copper articles occur in Michigan — 
and Minnesota. In the latter they are well distributed and — 
include eastern forms but are not numerous. Canadian imple- 
ments are nearly related to those of New York, and the shores — 
of Lake Ontario and the St Lawrence have afforded many. — 
Others occur on both sides of Lake Champlain. 3 
New England is fairly represented and has some notable forms. 
Pennsylvania has a number of implements and ornaments. Dr 
C. C. Abbott knew of 128 copper articles in New Jersey in 1885, _ 
but they were not all fully wrought. They included 11 celts, five 
spears, eight arrowheads, 18 bracelets, 70 beads and 21 pieces of © 
copper. At one time he had thought it “not improbable that 
all the copper articles found along the Atlantic coast were 
brought from western localities. A careful resurvey of many 
localities where ordinary Indian stone implements occur in
