PREHISTORIC FISHING. 



Fig. 230. — A fine single-barbed harpoon-head of elk-horn, in an excellent 

 state of preservation. It measures nearly ten inches and a half in length, and 

 has a thickness of about half an inch in the middle. The broad lower part shows 

 two shoulders, but its base, instead of being worked thin, is more than one- 

 fourth of an inch thick. The head, nevertheless, may have been detachable. 

 This specimen was presented to the National Museum, with other valuable relics,
