By drainage operations, crannogs were laid bare in the Lakes Ardakillin, Cloonfinlough, and Clonfree, near Strokestown, in 1852. These proved exceptionally rich in ‘finds,’ consisting of implements and personal and domestic articles of bones, bronze, and iron. The surface of Cloonfinlough seemed to have been twice laid. Here a skull was found; and among the bronze articles was a lamp of Roman type. One of the four crannogs in Ardakillin yielded 50 tons of bones. The section of another is here given. ‘Under a slight earthy deposit, there was a deep layer of loose stones, bounded by an enclosing wall, the foundation supported by piling. The lower portion of the island consisted of clay, peat, and stones, mingled with strata of ashes, bones, and logs of timber. The various rows of oak-piling are shown in the section; the sheet-piling, driven in obliquely, formed an unbroken circle round the island.’[113] The ‘finds’ were numerous and varied, including bone pins and combs, articles of bronze, beads of stone, glass, and amber. Near the crannog was found a canoe 40 feet long, made from a single oak trunk; in it were discovered a skull, spear-head, and bronze pin. The skull showed that it had received twenty cuts with a sharp weapon, and though no one cut necessarily proved fatal, death no doubt ensued from the accumulated injuries. Up to the year 1857, forty-seven lacustrine dwellings had been discovered; and since then the work of investigation of these sites has been steadily carried on; and the number now known is over 230. Of these, Ulster has about one-half, and Connaught one-third. The Lisnacroghera crannog, near Broughshane, County Antrim, was discovered in 1882; but its features had been destroyed before a proper examination could be made of the site. Most of the ‘finds’ fell into the hands of the late Canon Grainger; many of them were of exceptional value, and will be treated of in another chapter.
