from Captain Robinson's collection ; Pig. 2 being the specimen pre- 
sented to the Academy. Fig. 5 in PI. x. represents an anvil-stone 
of altered lias, pitted on one side. Eig. 6 in same Plate is a spear- 
head, and PI. xn., fig. 2, shows a borer of flint, also found here. 
POETSTEWAET AND GeANGEMOKE. 
These two places may be considered as one, as they are on 
opposite sides of the Bann, and the objects found in them present no 
difference in character. I have given several accounts of the finds 
from Portstewart, and some of the more important objects are figured 
in the Journal of the Royal Historical and Archjjeological Association 
of Ireland, vol. viii., Fourth Series, p. 221. Arrowheads, scrapers, 
hollow scrapers, knives, borers, cores and flakes, hammer-stones 
anvil-stones, bored stones, beads of stone, cut bones and pottery, be- 
sides broken and split bones, teeth, and sea-shells were the principal 
articles found. Examples of most of these were obtained by ex- 
cavation from the old surface. I did not obtain any of the stone beads 
directly from the black layer, but they were all found near one of the 
old hearths, and a labourer who searched for them told me that the 
best plan was to dig over a portion of the black surface and scatter it 
about, and when it dried, and that the wind blew off the sand, beads 
were likely to be found. These beads are small and made of greenish 
serpentine, which, according to G. H. Kinahan, M.R.I. A., came 
probably from Donegal. About forty have been found altogether. 
Though the occupiers of these sites were within about three miles of 
the chalk rock on the one side, and about seven on the other, in 
either of which places they could have obtained abundance of large 
nodules, yet they do not seem to have availed themselves of these 
sources of supply, but to have been dependent on the pebbles of flint 
lying about on the surface, or contained in the raised beach. These 
pebbles are, to a large extent, small cores of the older series which I 
have already referred to, and which are found here, as well as at 
"Whitepark Ray. The flakes, cores, and implements are, therefore, 
smaller than those found at Whitepark Ray, where they had, as 
material for their implements, the large nodules direct from the chalk 
rock. Several flakes and some arrow-heads of obsidian, or pitchstone, 
w^ere found, and also some nodules of pumice, one of which had a cord 
track round it. A lamp of pottery was found by a workman, which 
is now in the Rev. G. R. Ruick's collection. It is supposed to be from
