The most interesting “find” was a bronze pin (fig. 229), very sharp at point, the superior portion of the acus ornamented with a row of circular indentations, and the flattened head pierced with a round hole, through which passed a thin golden-bronze loop, of material so fragile that it crumbled away when touched. The pin itself was covered with a thick coating of “patina” and boggy sediment, which at once scaled off; it is composed of early and pure bronze called “golden,” from its resemblance to the precious metal, and it is of the type of those found in the ancient _Emania_ destroyed in the third century. There were no traces of either bones or pottery; as the probable level, on which they might be expected to rest, was not reached. COUNTY ROSCOMMON. Twelve crannogs were discovered in this county during the working of the Commission for the Arterial Drainage of Ireland: these sites have all been identified. _Loughlea._--A flint mass, a piece of a circular grindstone, a fragment of a bone spike, two portions of the blades of iron swords, and an antique-shaped iron key, were here brought to light. There were three crannog sites in this lake.[249] _Muckenagh._--Ante, p. 154. _Derreen Lake._--There were here found an iron hatchet and a pair of stirrup irons.[250] _Kilglass._[251]--Of this site the name alone is given. _Cloonfree_, _Cloonfinlough._--In the year 1852, by the operation of drainage works in the vicinity of Strokestown, the level of the three lakes of Cloonfree,[252] Cloonfinlough, and Ardakillen was greatly lowered, and one artificial islet in the first-named sheet of water, and two in Cloonfinlough were laid bare. Of the latter, one island was one hundred and thirty feet in diameter, constructed on oak piles driven into the soft marl at regular distances, bound together by horizontal oak stretchers forming a triple stockade, with an interval of five feet between each. To the N. W. were a number of irregularly-placed piles, stretching a short distance from the islet. The centre of the stockades was laid with trunks of small oak-trees, placed flat on the marl; they all pointed to a common centre, thus forming a platform whereon the island itself was constructed. When first observed, there was jutting out from the island, towards the west, a kind of jetty or pier, formed of a double row of piles and stretchers running parallel, and about eight feet asunder, on which logs of timber were laid closely and horizontally.
