_Slievemore Cromlech._--Similar markings may be observed on one of the upright stones of a ruined cromlech standing on the slope of Slievemore, island of Achill, amongst other remains, styled on the Ordnance sheet tumulus, cromlech, Danish ditch, respectively. It is difficult to imagine that the likeness between these two sets of cup-markings is accidental. A similar array of four cups, but placed vertically, may be seen on one of the enormous stones forming the right-hand side of the gallery leading into the great cairn of Newgrange. * * * * * _Lennan Cromlech._--The inscribed cromlech of Lennan or Tullycorbet, Co. Monaghan, stands upon a knoll called by the people of the district Cruck-na-clia, which may be translated ‘Battle hill.’ This monument, a fine one of its class, presents every appearance of having always been free-standing. It bears some extremely curious markings, into the character of which the late Sir Samuel Ferguson made careful examination.[36] * * * * * _Castlederg Cromlech._--This monument lies about three-quarters of a mile to the north of the town of Castlederg, 140 yards to the east of the old Strabane road, leading through Churchtown townland. The principal cap-stone was dislodged many years ago by the owner of the farm. ‘It appears,’ says Sir Samuel Ferguson, ‘that the structure had previously been rendered insecure by a stone-mason, who had abstracted one of the supporters for building purposes; and it was suggested that the motive for casting down the cap-stone was an apprehension lest the owner’s cattle, in rubbing or sheltering under it, might do themselves a mischief. That the inscription was there at the time of the first disclosure of the upper face of the support on which it is sculptured, is the common and constant statement of the people of the country; but the case rests more satisfactorily on the fact, wholly independent of testimony, that a collateral covering stone remains _in situ_, and that the line of scorings is prolonged underneath it into a position too contracted for the use of a graving tool.’[37]
