PLATE 6. 



FIG. IT. — SCRAPERS, ETC. 



\ Full Size. 



The flint implements known as scrapers are very common, 

 chiefly in Antrim. They are found on the sites of ancient 

 settlements, and are distributed over the surface of the ground. 

 They are formed by chipping away the pointed end of the flake, 

 which forms a more or less circular end. Sometimes the scraper 

 is carefully chipped into a disc-shaped implement, sometimes 

 into a spoon-shaped, with every variety of form between the 

 two. The chipped edge is sometimes extremely blunt, but 

 generally the scraper has a bevelled edge all round. 



The lower row of implements in the illustration shows some 

 of the variety of forms into which flakes are converted by a 

 system of secondary chipping. 



FIG. 12. FINELV-CHIPPED ARROW-HEADS. 



\ Full Size. 



The most beautifully-formed and elaborately-chipped flints 

 found in the North of Ireland are the arrow-heads. They assume 

 an endless variety of forms, all developed from the original 

 simple leaf-shaped flint-flake. In the arrow-heads, all the 

 characteristic points of the simple flake are obliterated by an 

 elaboration of surface-chipping, and the ultimate forms assumed 

 are the result of development in two lines : one in the direction 

 of hollowing out the base of the leaf-shaped flake, and the 

 other in the direction of forming a definite stem or tang at 

 the base of the flake. All the forms are distinguished by care- 

 ful surface-chipping, and they occur from § of an inch long, to 

 4 and 5 inches. The spear heads are very much larger and 

 are commonly ground on the flat surface. The illustration is 

 from a group of the normal forms found in Antrim.
