A front and side view (fig. 31) is given of an iron adze, six inches and a-quarter long, from the crannog of Lisnacroghera, as were also the three objects of iron here represented (figs. 28, 29, 30), the uppermost, probably a knife, and having a hole through what appears to have been the haft end. The other two articles are said to be the remains of a saw, and the long fragment, perforated in four places, is supposed to be the strengthening bar attached to the piece of wood into which the back of the saw had been inserted. [Illustration: Figs. 28, 29, 30.--Iron Objects from Lisnacroghera.] [Illustration: Fig. 31.--Front and side-view of Iron Adze from Lisnacroghera.] _Hones._--Hones and sharpening stones are very commonly met with in crannogs; they plainly denote that at some period during their habitable existence the occupiers possessed metallic weapons or tools. The Cornagall “find” presents two specimens of whetstones; one is given (plate XIII. fig. 7); the material dark-grey in colour, almost black, extremely hard, and close-grained; they are symmetrical in form, and partake greatly of the character of the so-called touchstones. Fig. 32 is a perforated example. [Illustration: Fig. 32.--Whetstone.] _Armour._--Amongst crannog “finds” no well-authenticated remains of defensive armour have been recorded, with the exception of a fragment of chain armour from Inisrush, and the ancient “golden bronze” shield from Lough Gur. The armour found on the site of the crannog in Lough Annagh is not here taken into consideration, it being evidently seventeenth century work. In the townland of Monea, about five miles from Enniskillen, county Fermanagh, in a small but deep lake,[97] there is a very fine circular crannog, about seventy-five feet in diameter, composed almost entirely of timber, and surrounded with remains of staking; a complete examination of the site was not possible, owing to the thick mass of roots and fibres thrown out by the trees with which it was studded. Upon digging into that portion of the shore offering the greatest facility, there were discovered several fragments of bones of the _Bos longifrons_ and other animals, quantities of charcoal, some iron slag, and the remains of the curious iron helmet here figured, which must, however, be viewed as of comparatively modern date. The helmet is entirely devoid of ornamentation, is acutely conical in shape, and no traces of nasal or cheek pieces remain. A casque, very similar to this, was found in the river Nore, near Borris-in-Ossory, Queen’s County, and is preserved in the Museum of the Royal Irish Academy.
