PREHISTORIC FISHING. 



The pebbles out of which, as stated, such sinkers are made, generally present 

 a more or less compressed oval form, and vary in size from less than an inch to 

 six inches and more in the greater diameter. Most of these specimens in the 

 National Museum, particularly the larger ones, have been obtained from the New 

 England States ; Oregon has furnished quite a number of small ones, and the 

 others came from Pennsylvania, Tennessee, Ohio, Kentucky, the District of Co- 

 lumbia, and California. 



Fig. 262 (on page 161). A large pebble of oval outline, measuring two 

 inches and three-fourths in its thickest part, and surrounded by a pecked groove. 

 The material is a granitic rock, in which feldspar prevails. This specimen was 

 found at Tiverton, Newport County, Rhode Island, and belongs to a collection of 

 New England relics obtained from Mr. J. H. Clark. 



Fig. 263 (on page 161). A specimen of similar form, but of greater thick- 

 ness, being nearly circular in the section crossing the groove, which is rather 

 rudely pecked, and forms the only alteration of the sandstone pebble. Found 

 at Dos Pueblos, California, by Mr. Schumacher.

Fig. 264. This specimen shows a carefully pecked groove, and its longitu- 

 dinal sides also have been shaped by pecking. It has in the middle (near the 

 groove) a thickness of two and a half inches. The material is like that of the 

 original of Fig. 262. From Chilmark, Island of Martha's Vineyard, Massachu- 

 setts. Clark collection. 



Fig. 265. A smaller object of the same shape and material. The groove 

 appears to be the only modification of the pebble. From Newport, Rhode 

 Island. Clark collection.
