118 PREHISTORIC FISHING. 



quence of exposure, the specimen showing a kind of polish evidently produced 

 by contact with other bodies. It looks as though it had been drifted in water.

Fig. 171 shows the form of a somewhat similar object, in this instance 

 brought into shape by grinding. This specimen, presented by Professor W. A. 

 Kite, is not flattish like the one first described, but almost round in the cross- 

 section, and terminates in tolerably sharp points. It consists of a blackish kind 

 of stone, apparently argillite, and was found nearly opposite the mouth of Middle

 implements collected in the National Park by Superintendent P. W. Norris, con-

 alone is the noticeable feature, and that is certainly exceptional and suggestive 

 of the application here considered. The notches would have facilitated the attach- 

 ment of a line, and the implement, inserted into a fish and swallowed by a larger 

 one, could not easily have been disgorged by the latter. But, nevertheless, it 

 probably was prepared for a totally different purpose. 



I give in Fig. 173 the delineation of a rather large polished implement, 

 found in Berks County, Pennsylvania, and presented to the Smithsonian Insti- 

 tution by the Hon. Gr. H. Keim. I figure this specimen for the simple reason 

 that it has been regarded by some as a bait-holder, an opinion in which I cannot 

 concur. The material is a greenish-gray argillite. The illustration shows its 

 form distinctly, and I have only to add that a cross-section laid through the
