[Illustration: Fig. 26. Bronze enamelled object from Lisnacroghera. Full size.] In a small lake called Cornagall (_the Hillock of the Dane or Stranger_), about six miles from Cavan, there is an almost circular artificial island, thirty yards in diameter, its crannog nature, attested by rows of oaken stakes fencing its margin, showing above the summer level of the lake. In August, 1869, the water being then particularly low, a log of timber that bore evident traces of manual labour was ascertained to be the end of a “dug-out” embedded in soft, boggy matter. It proved, however, to be only a fragment, the other portion having been destroyed by fire, as evinced by the charred appearance of the remains: the large quantity of charcoal, half consumed sticks and chips visible on the margin of the crannog indicated its destruction also by that element. A set of iron tools lay on the floor of the canoe thus discovered, all here represented one-third their real size. The following is a brief description of them:-- Plate XIII., No. 1, is an adze in a perfect state: the metallic portion consists of soft iron, well steeled to a considerable distance from its cutting edge. No. 2 is an adze, scraper, or implement of the same class, but differing from the former in that it shows no perforation; its narrow-pointed end had evidently been intended for insertion in a wooden handle: the edge being broken, it is impossible to determine whether it had been steeled. No. 3 is a hammer of iron, the handle of oak, split at its upper extremity for the insertion of a wedge, which still remains. No. 4 is a celt or chisel--a somewhat similar object (from Lagore), but considerably broader, is preserved in the Museum of the Royal Irish Academy. Nos. 5 and 6 represent a thin, knife-like piece of iron and a wooden handle, originally, perhaps, portions of one implement; the wood, hollowed for reception of the blade, is perforated for the insertion of a rivet, which no longer remains. With the iron tools in the canoe was found a remarkable object, composed of oak, use unknown; it is curiously notched upon one of its sides, near the edge. Figs. 8 and 9 represent two views of it.[96] [Illustration: Fig. 27.--Iron Axe-head from Lagore.] Fig. 27, an iron axe-head, from Lagore, is seven inches in length, massive, and of considerable weight; the cutting edge singularly narrow. A great number, made of stone, have come to light; and all that are composed of iron are well steeled round the cutting edge. Axe-heads are of great diversity of form.
