wliich it vras destroyed or covered. It is shown on the 1840 maps 

 as a large slab supported by smaller ones, and was evidently a 

 cist. 



O'Eeien's Beidge. 



O'Brien's Bridge is a straggling late parish, and cuts into the 

 Glenomera and Broadford valleys at their junction to the north-east, 

 l^ear this point stood a dolmen, and another one lay at the further 

 and lowest ridges of the hills to the south-east, three miles away. 



(47). Lackaeeagh, O'Brien's Bridge Parish (0. S. Sheet 44, l^o. 8). 

 — This cist is shown on the map of 1840 as a large regular slab, 

 evidently the north side, against which a long and more irregular slab, 

 of about the same size, is leaning, with its nearer end on t)ie ground. 

 It is there called "Dei-mot and Grania's Bed." When Mr. Borlase 

 visited the site, there were only the remains of a cairn ; and it is 

 only shown as a "site" on the map made in 1893 (published in 

 1898). It stood near the summit of the hiU above Glennagalliagh^ 

 Yalley, nearly 1180 feet above the sea. The stream and gorge of 

 Aillenagommaun runs down the flank of the hill to the north. 



(48). Aedxataggle,2 O'Brien's Bridge Parish (O.S. Sheet 53, 

 iN'o. 4). — This dolmen lies on the northern slope of a low ridge, not 

 very far from Bridgetown and O'Brien's Bridge, near the so-called 

 " Cromwell's-road." It commands a fine view of the great bluffs of 

 pni-ple and brown wliich we have been exploring. It is embedded in 

 deep heather and bracken ; and its interior is a veritable garden of 

 delicate ferns and son-el. Mr. Borlase," in publishing a version of my 

 notes, considered that there had been a row of enclosing slabs roimd 

 the tomb. I do not think this was the case, as none of the sup- 

 posed "peristyle" is standing, and no loose blocks (even) lie to the 

 north. It is shown on the 1840 map as a large block, supported on 

 two others. It is reaUy a complex cist, with two if not thi-ee compart- 

 ments ; the most perfect resembling the little sketch on the map, and 

 is about 8 feet 6 inches. At the west end are two large slabs, 6 feet 

 6 inches long, the more eastern forming the end of the cist. The 

 fii'st compartment of this is formed of irregular gritstone blocks ; the 

 cover is 7 feet 3 inches long, 5 feet to 6 feet 6 inches wide, and 

 11 feet to 20 inches thick. Bevond this the cist continues in a very
