 sey. 



50. Thirteen fragments of pottery : Bur 



lington County, New Jersey. 



51. Two hundred and two notched peb- 



bles : Point Pleasant, Bucks 

 County, Pennsylvania. 



This series of notched pebbles, or 

 &quot; net sinkers/ was found buried at 

 Point Pleasant, Bucks County, 

 Pennsylvania. It has been claimed 

 that these simple implements had 

 also other uses than that indicated 

 by the name of net sinkers,&quot; which 

 is very probable, as they are fre 

 quently found in ash pits and in 

 other places a great distance from 

 the water.

1. Ten argillite stones, roughly flaked : Trenton, New Jersey. 



2. Argillite stone, roughly flaked : Morrisville, Bucks County, Pennsylvania.

sylvania. 



These objects were discovered in a cache in an island in the Delaware River, 

 Bucks County, Pennsylvania, by Mr. Henry C. Mercer, of Doylestown, Penn 

 sylvania. 



Deposits of objects of the same kind, apparently intended to serve as materials 

 for the manufacture of implements, have been discovered in various localities 

 east of the Mississippi River. The continuation of The History of Travaile 

 in Virginia, by William Strachey, treats of this subject. 



Their maize and, no doubt, their copper, hatchets, horses, wampum, beads, and 

 many other of their articles were of great value, owing to the estimation which 

 they attached to them. The Indians hid them from each other in the earth or 

 the woods, where they kept them whole years, until they needed them. 



9. Flat stone, with worked edges : Found in the cache above mentioned. 



10. Four spearheads : Lumberton, Burlington County, New Jersey. 



11. Eight spearheads : Lumberton, Burlington County, New Jersey. 



12. Thirteen spearheads : Trenton, New Jersey. 



13. Four arrow or spear heads : Trenton, New Jersey. 



14. Nine flaked blades, usually described as knives, but probably &quot; blanks,&quot; which 



were made to be wrought into arrowheads, etc. : From a cache containing some 

 200. Lumberton, New Jersey. 



15. Flaked stone, probably a &quot;blank:&quot; From a cache which contained some 150 



similar specimens, found in a meadow about 3 miles south of Trenton, New 

 Jersey. 



NOTE. According to the observations of Mr. William H. Holmes, it was custom 

 ary to dress the stones in the quarry in the manner resembling Nos. 14 and 

 15, in order to facilitate their transportation. The form that was wanted was 

 afterwards given to these &quot;blanks.&quot;

17. Two flaked stones, resembling the preceding : Burlington County, New Jersey. 



18. Flaked implement : Burlington County, New Jersey.
