Amongst the debris of crannogs have been found several designs carved upon the polished surface of the larger bones of mammalia. Sir W. Wilde observed that clear, sharp, and accurate impressions might be made from some of these carvings in the same way that proofs are taken from a woodcut. In some instances the pattern is elaborately finished, and would answer equally well “as a design for the panel of a stone cross, the decoration of a doorway, or cornice of a round tower, a compartment of a brooch pin, the capital of an early ecclesiastical archway, the illumination of a MS., or the graving of a piece of warlike furniture.” An example of this kind of decoration is shown on plate XXXII., fig. 1; it is the leg bone of a deer, 8½ inches long, highly polished, and covered with carvings; its precise use is as yet conjectural. Figs. 3, 4, 5, are _fac-similes_ of the embossed patterns on this bone. [Illustration: Plate XXXII. Fig. 1. Decorated Bone from Ardakillen. One-third real size. Fig. 2. Decorated Bone from Lagore.

Use unknown.] Another carved leg bone of a deer (plate XXXII.), fig. 2, is stained a dark brown colour, probably by lying in peat; its polished surface shows how much it had been handled. Upon the surface of this bone there are various devices traced with a graver or other sharp tool. Figs. 6, 7, 8, 9, represent these (full size), and figs. 10, 11, 12, are characteristic of Celtic animal ornamentation. [Illustration: Fig. 189. Fig. 190. Fig. 191. Fig. 192. Fig. 193. Plates of Bone, decorated, use not known.] In the Museum, R. I. A., there are eight thin plates of bone, varying in length from 1 to 5½ inches; they are of every variety of shape--square, triangular, irregular, but the majority oblong. In some respects they resemble in form, size, and ornamentation, the class of small stone articles supposed to have served as toys, amulets, or in some kind of game. According to Wilde, however, their more probable use was either for the decoration of small caskets, or for dress fasteners. They are generally perforated in several places, and the foregoing illustrations display great variety of outline. Their outer surface, smooth and convex, was more or less decorated with a number of circular indentations and dotted lines. Most of the specimens were found in the crannogs of Ballinderry and Ardakillen. [Illustration: Fig. 194.--Rude Bone Spoon found at Clooneygonnel. Two-thirds real size.]
