The first figure to the left, plate XV., represents an object of the same class, but slightly smaller, and not so much ornamented. To the right are two views of another article, which presents all the appearance of an umbo. On the same plate (XV.) are four bronze rings: one of them is formed of two very thin plates, secured together by rivets of the same material; the three remaining rings are solid, and of a class which some antiquaries suppose formed a kind of defensive armour. It is imagined that they were attached pretty closely together to portions of the ancient warrior’s garment; and it is worthy of remark that in the collection of the Academy a number of such rings, or objects very like them, may be seen looped together by bronze fastenings.[99] [Illustration: Fig. 35. Stone Mould from Lough Scur.] [Illustration: Plate XV. Boss-like Objects, and Rings of Bronze, from Lisnacroghera. Full size.] Stone moulds, evidently employed in casting celts, weapons, tools, and other articles of bronze, have been brought to light. Fig. 35, discovered in the Crannog of Lough Scur, county Leitrim, is a triangular block of coarse white sandstone 7½ inches long, 5¼ wide, and 3½ thick, having both sides indented for castings. On the side here presented are moulds for a plain celt three inches long, and another celt four inches long, with cross strop and ring for attachment to the shaft. Castings taken from this mould “delivered” implements closely resembling several in the Museum, R. I.A.[100] At Lough Ramor, county Cavan, a very curious block of sandstone was found, having a mould on three of its faces: the one here represented is for a broad arrow-head, with side rings. Upon the obverse is one for a small spear and leaf-shaped arrow; on the right side is another arrow-mould.[101] [Illustration: Fig. 36. Stone Mould from Lough Ramor.] _Vegetable Remains._--The ancient Irish set great value upon the hazel plant, a fact demonstrated by the frequent mention made of it in their best and oldest MSS.; the numerous round stones met with in crannogs are supposed to have been used for breaking the nuts; their shells form the most considerable portion of vegetable remains in the kitchen middens, where beech nuts also are present; and it is known that within historic times the Irish kept large herds of swine that fed on masts in the woods, for then “The forests cast their fruits in husks and rind.” Grain (species not stated), and various kinds of wild fruit, have been discovered; walnuts at Lough Nahinch, cherrystones at Ballinlough.[102]
