2. Three copper celts, a fragment of a fourth (butt-end), a copper halberd, and a short blade of copper of somewhat similar form, found in 1892, near Birr, King's County, formerly in the collection of Mr. Robert Day, of Cork. (Fig. 2.) 3. Three copper celts found in 1868, when ploughing at Cullinagh, near Beaufort, Killarney, County Kerry. (Day Collection.) 4. Two large and well-formed copper celts found together in street excavations in Suffolk Street, Dublin, in May, 1857. (Ray Collection.) (Fig. 4, nos. 1 and 7.) [Illustration: Fig. 2.--Birr find.] 5. Two copper celts found together at Clontoo, near Kenmare, County Kerry, in 1906. (Fig. 4, nos. 2 and 3.) 6. Six copper celts found together at Cappeen, County Cork. The distribution, analyses, types, and finds show that the copper celts represent a period when copper was in common use throughout Ireland and before bronze was generally known. The celts from the Ray Collection mentioned above show that the fully developed celt was in use during this period, while the "Birr find" with the halberd shows that the halberd was also known and in use during the full copper period. [Illustration: Fig. 3.--Copper Knife and Awls found at Knocknague.] Moulds for casting flat celts, copper and bronze, have been found in the following places in Ireland:--Carrickfergus; Ballymena; Loughgall, County Antrim; Ballynahinch, County Down; and Lough Scur Crannog, County Leitrim.[10] [10] Crawford, "Early Bronze-Age Settlements in Britain," Journal Royal Geographical Society, 1912, p. 217. Copper celts have been found practically over the whole country; and the following is a list of those in the National Collection, of which the localities are known, and, as well as these, there are about eighty for which the provenance has not been exactly recorded:-- LIST OF COPPER CELTS FOUND IN IRELAND.
