are serrated, probably they may have been used as saws. Fig. 3 re- 
presents one of these objects, but the woodcut scarcely does justice to 
its neatly serrated edge. 
Of arrow-heads I have about twenty that are perfect, and about 
the same number of broken specimens. The Marchioness of Down- 
shire has fully as many, I should say, very beautiful and perfect. 
They show very fine and skilful workmanship, and the porcellaneous 
glaze which has been imparted to them by exposure on the sand has 
added much to their beauty. Several types are very well represented— 
stemmed, indented, triangular, leaf-, and lozenge-shaped. One of 
those in my own series, which had been broken at the point, has had 
the broken part dressed for use as a scraper. 
There are several dressed flakes and awls. Some of the flakes are 
only dressed round the edges, but others are dressed over the back, 
showing as fine chipping as that on most arrow-heads. This kind of 
implement appears to be commonly found along with the burned bones 
in interments. Several of these are figured by Canon Greenwell in 
‘‘ British Barrows,” some of them being beautifully serrated. Among 
the bones found in a burial urn which lately came into possession of 
Canon Grainger, a burned specimen of this kind was found, and in 
another urn, which was found at Cullybackey, there had been a similar 
implement, as I picked up a portion of it from among the bones, which 
were scattered, before I was able to secure them. 
Several flat and thin flakes show evidence of having been used as 
knives, though no trouble has been taken to dress them into shape. 
Cores are plentiful, but all are small, showing the outside weathered 
crust, and thus indicating the nature of the material used. I believe 
the people had been entirely dependent on such small boulders as they 
could procure from the drift and around the sea shore, and that very 
probably none of the flint had been either brought by them, or pro- 
cured by barter, from a distance. Everything shows that the flint was 
not so plentiful as they could desire, and other material was tried. I 
procured several neatly-formed flakes of quartz crystal, and a scraper 
of greenish rock, of a kind found plentifully scattered about. I ob- 
served several other flakes of various kinds of stone, which I believe 
were used as scrapers; but all stones except flint have suffered so 
much from weathering that one cannot always speak with certainty of 
the artificial character of any marks which appear on them. 
Several stone hatchets were found, but only the one which I exca- 
vated, and have already described, was derived directly from the black 
layer; but that the inhabitants manufactured hatchets I think there 
can be no doubt, as I found a stone object with two grooves into 
which the flat side of a stone hatchet would fit when being rubbed 
backwards and forwards to polish it; and I think it is probable that 
the stone referred to could be used for no other purpose. The hatchet 
which I dug out of the layer appeared as if it had never been used ; 
and stone of a similar greenish colour to that from which it is made 
oceurs among the hills.
