IMPLEMENTS MADE OF BONE.

Mr. Dall on San Miguel Island (P. M. 13737), and several others of nearly 

 the same size obtained by Mr. Schumacher on the island of San Clemente 

 (P. M. 13539). 



Another form of implement, of which there are several examples 

 among the later collections from San Clemente, is a sort of polishing bone 

 (P. M. 13532) identical in shape with those from the sites of the ancient

ple here represented (Fig. 109) to three times that size. They are smooth 

 and often highly polished at each end, and appear to be made from the 

 small ribs of cetaceans and other animals. 



An interesting pin-like article, shown in Fig. 110, was obtained by Mr. 

 Schumacher from a grave 

 on the island of San Cle-

importance from its resem- a bone pin.

 Tennessee. 



The later collections from the islands have also brought to light sev- 

 eral implements made of the hollow bones of large birds. One of these 

 from San Clemente (P. M. 13531) is represented b}^ Fig. 111. Mr. Schu- 

 macher thinks that implements of this character were " marrow-extractors."

"Marrow-extractor" made of bone, i. f the bone, as shown 



in the figure. In this single example the opposite end has a groove cut 

 around it as if for the attachment of a string. 



Many other bone implements more or less allied to those here described 

 have been received from the later explorations. The most interesting of these 

 are three thin-pointed bones (P. M. 13129), each perforated at the broad end 

 by a small eye, and which, there is hardly any reason for doubting, were 

 used as needles.
