called ''slag" would lie about among the sand, a few here and there, 
just as we find them at present. Grains of sand may be seen mixed 
with, and adhering to, the small lumps of smelted iron, which is most 
easily explained by supposing the smelting to have taken place in the 
accidental way I have suggested. In the primitive smelting furnaces 
in Africa the ore is placed in a hole in the ground previously heated, 
and fires are then put round it to smelt it and a channel is made to 
a hole at a lower level for collecting the molten matter. At Grangemore 
the smelting would be done in just such a primitive way as is carried 
on in Africa ; but instead of collecting the smelted matter it was 
allowed to drop among the sands. It' must be remembered also that 
the railway from Coleraine to Londonderry passes through the centre 
of the Grangemore sandhills, and that it is fenced on each side by a 
wire railing, the standards of which are soldered into stones. Pits lie 
close along each side of the railway ; and many of the objects mentioned 
by Mr. Hasse in his paper were, I believe, distributed at the time the 
railway was being made. In many instances, where the iron objects 
are not rusted beyond all recognition, they show their modern character. 
Othee Sites. 
At Fintragh, County Donegal, I found indications of a small 
settlement, as mentioned in the introduction. The sandhills had been 
previously cultivated, and are now covered with grass, but I found 
amongst other indications two anvil-stones with a pitted mark on one 
side of each. Ilear Cranfield Point, in County Down, I found low sand- 
hills with cores and flakes. From finding at Bundoran chert-flakes 
and implements among the weathered carboniferous limestone, I 
examined the talus of weathered chalk along the Coast of Antrim, near 
Glenarm, and found flakes and cores. I also found in a field near the 
same place the site of a manufactory, and brought away cores, 
hammer- stones, and scrapers. I have been twice to Horn Head, 
near Dunfanaghy, since reading my last Eeport, and have each 
time examined the hut-sites there. I found several good examples of 
hammer-stones, a very perfect bone pin, pieces of pottery, and many 
pieces of split crystalline rock which I believe had been used in cutting 
and scraping. I also learned from a person living in Horn Head that 
not many years ago the hut-sites, which are now quite bare, were 
covered with high sandhills, which hid the view of the sea from the 
inhabitants living inland. I have been twice at Sligo in the hope of 
finding chert implements, but as yet without success. Other sites
