material, I found a flint boulder, weighing over a pound, in its 
natural state as it came from the chalk. Several other pieces of flint, 
deeply patinated and core-like in character, were picked up. The rocks 
in the neighbourhood of the shore show glacial grooving and scoring 
very plainly : therefore I believe that glaciers were the agents which 
brought the flint to Donegal Eay. The number of flint implements 
found amongst those of chert at Eundoran was considerable, and 
appeared to me at first to be an indication of commercial intercourse 
between the Stone Age people of Antrim and those of the West Coast 
of Ireland ; but seeing that I cannot trace chert in any of the sites 
near Bundoran, and observing the coarse material used for implements 
in stations which could as easily have been reached by traders as 
Eundoran, I am of opinion that the flint implements found there are 
not an indication of trading, but that they were made from flint pebbles 
and boulders found on the seashore, and that these were derived from 
the boulder clay.

I visited Eunbeg in the summer of 1889, and found sandhills there 
with the old surface layer exposed in many places. I saw no flint, but 
in digging over the layer there was the usual mixture of shells, bones, 
and broken pieces of crystalline rock. I got several good and well- 
marked examples of hammerstones and two pieces of pottery without 
ornament, but with a small pole in each of them near the rim, probably 
for the purpose of suspending the vessel. The rounded, waterworn 
pebbles were evidently broken or split intentionally for implements, a 
very good cutting edge being formed by the junction of the fractured 
■ side of a spall or flake, with the rounded outside of the pebble. A 
i flake of this kind could be used either as a scraper or an axe, but no 
:one would be likely to take them for artificially produced fiakes or 
i implements if found alone. Finding them, however, in association 
with hammerstones, shells, and bones in the black layer, satisfies me 
that they were intentionally made for cutting and other purposes. 
Skull Island is connected with these sandhills. It is described by 
Mrs. Craik in one of her articles entitled *'An Unknown Country," in 
the Englishwoman's Magazine for May, 1887. On a visit which she 
made to the place she found to her amazement, in a heap of sand, ''a 
quantity of bones — leg-bones, arm-bones, skulls — lying so close to the 
surface that, with a stick or umbrella, you could have digged them out 
of the sand by dozens." She disinterred two skulls, one of which got
