the Indians in the neighborhood of New Amsterdam (now New 
York) employed, during the middle of the seventeenth century, 
various kinds of nets; but this author does not state whether 
these nets were original Indian inventions, or adopted from the 
Dutch colonists. The Natchez, on the Lower Mississippi, made 
their nets from the bark of the linden tree, and knitted them quite 
in the European fashion.* 
Reverting, in conclusion, once more to netsinkers, I will men- 
tion that in the United States there also occur some provided 
with a perforation, instead of being notched. I had occasion to 
examine in the collection of Col. Charles C. Jones, of Brooklyn, 
a number of the perforated kind, which the owner had found in 
Eastern Georgia, at the confluence of the Great Kiokee Creek 
with the Savannah river, a spot where Indian relics abound. The 
material of these sinkers is the taleose stone commonly called 
soapstone. They consist of flat smoothed pieces, of indefinite but 
- mostly rounded outline, which are an inch or less in thickness, and 
measure from three to six inches in diameter. The holes are usu- 
ally drilled from two sides, and therefore narrowing in the middle, 
where they are about half an inch wide. Col. Jones will figure 
and describe these Indian implements in his forthcoming work on 
the antiquities of the State of Georgia.

hase the many extinct animals of interest hitherto discovered 
‘in the Tertiary of the Rocky Mountain region, none, perhaps, are 
more remarkable than the huge mammals which have recently been 
described from the Eocene beds of Wyoming. It is important, 
_ therefore, that accurate information in regard to them should be 
: promptly made public, especially as serious errors on this subject 
have already appeared in various scientific ait and are 
being widely disseminated.
