140 INDIAN NETSINKERS AND HAMMERSTONES. 
Netsinkers and hammerstones are found in various localities of 
the United States; but I am not aware that they occur in any 
other place as frequently as in the neighborhood of Muncy. Net- 
sinkers have been taken away from there by the hundred, and yet 
their number is not exhausted; hammerstones, however, although 
likewise numerous, occur there less frequently. The other produc- 
tions of primitive art, which always indicate the former presence 
of the Indians, such as stone tomahawks, wedge-shaped stone 
implements, flint arrowheads, fragments of coarse pottery, "i 
are ħlso found in the environs of Muncy. 
The netsinkers in question are flat pebbles of roundish or angu- 
lar (generally indefinite) shape and of various sizes, which exhibit

Netsinkers (one-half natural size). 
on two opposite points of the circumference an indentation or 
notch, more or less deep, and produced by blows. Besides the 
notches, which facilitated the attachment to the nets, these pebbles 
have not undergone the slightest change by human agency; and ~ 
their manufacture, therefore, required but little labor and skill. _ 
_ My smallest specimen measures two inches in diameter and weighs 
oe only half an ounce; my largest one, a flat stone of irregular out- 
line, is eight inches wide across the broadest part and weighs two 
pounds and fourteen ounces. I must mention, however, that the 
last-named s is seiasaelly es and heavy, the S size
