with a long stone drill, instead of the reed used in the other 

 specimens. 



Plate XXIV, 1. Small stone of triangular shape, ground 

 but not polished. The centrum has a small facet on either 

 side, and the edges of the bore are chipped at the bottom. The 

 bore is not in the middle of the centrum. The wings are very 

 thick and square edged. It has been bored from one end and 

 shows circular markings. 



Plate XXII, 1. Large stone of peculiar form, ground and 

 polished. The centrum extends beyond the wings at the 

 bottom, and one side is rounded, the other has a well-marked 

 facet. The wings are very broad and short, so that the effect 

 is that of a mace head rather than a bannerstone. The wings 

 are thick and ground to an edge all round. It has been bored 

 from both ends, and the bore shows circular markings. 



With the exception of the three small and the mace-shaped 

 bannerstones, the group is fairly homogeneous, and hence offers 

 an unusual opportunity for study. A careful comparison has 

 been made for the purpose of determining: (1) what were the 

 methods of manufacture, and (2) what uses could they have 

 been put to? In the first case the evidence is clear, and verifies 

 the observations of other investigators, that the bannerstones 

 were first roughly chipped into shape, then pecked and ground, 

 and finally polished. In one object, intermediate in form 

 between the bannerstones and the crescent-shaped stones 

 the pecking had been dispensed with, and the shaping done 

 by rubbing with some instrument which left broad shallow 

 striations. Similar striations are present in a few of the banner- 

 stones, but the finishing seems to have been done with a piece 

 of fine-grained sandstone, or with sand and water. All the 

 stones, with the possible exception of No. 19, were drilled with 

 a reed and sand. The boring was begun at the bottom and 

 carried through, or carried about two-thirds of the way, and 

 then finished from the other end. The exactness with which 

 the two borings meet shows a high degree of skill. In several 

 cases the diameter of the bore has been enlarged at one or both
