originally composed it being upright ; the centre stone is wanting 

 here, but on the outside are a lofty pillar-stone and a crora-leac» 

 an uncommon, but not quite singular union. Possibly this may 

 have been caused by the crom-leac being often used in bloody sacri- 

 fices, while the pillar-stone was employed in the rites peculiar to the 

 adoration of fire ; the two ceremonies may have most commonly 

 been separately performed. One of the most remarkable of these 

 stones is to be seen in tlie little island of Innis-Murray, off the coast 

 of Sligo,* where a conical pillar, called by the natives, the Clogh- 

 Griane, or sunstone, rises from a square pedestal of masonry, sur- 

 rounded at some feet distance by a low thick wall, to preserve it 

 from profanation ; close to this wall is an artificial mound of earth, 

 irregular in shape, and containing small cells, vaulted with rude 

 stones ; some of these are perfect, having a hole in the top, and a 

 small one in the side, apparently for the admission of air ; many ' 

 however have fallen in. in these cells, which bear a strong resem- 

 blance to the chambers described in Mount Olivet by Dr. Clarke, 

 the frightful rites of initiation were probably carried on. Fronting 

 the tumulus and the sun-stone, there is an area, where it is likely 

 the worshippers assembled ; the whole of which, with the pillar and 

 tumulus, is enclosed by a wall ten feet high, and from five to ten 

 feet thick, built of huge stones without mortar, but extremely well 

 put together. The enclosure forms a sort of irregular ellipse, having 

 two enclosures, but so narrow, that a man can hardly pass through : 

 near one of them is a circular cell, not in the wall, but in a kind 

 of enlargement of it which projects into the oval space. This 

 pagan monument had been sanctified by St. Columba and St. Mo- 

 laise, who each built a small chapel, one in the area before the
