SCOTLAND AND IRELAND 



Further north is a remarkable group of monu- 

 ments known as the Carrigalla circles. The first 

 is a plain circle (L) 33 or 34 feet in diameter, 

 composed of twenty-eight stones. The space 

 within them is filled up with earth to form a 

 raised platform. At a distance of 75 feet are two 

 concentric circles, diameters 155 and 184 feet 

 respectively, made of stones 5 or 6 feet high. The 

 space between the two circles is filled with earth. 

 Within these is a third concentric circle about 

 48 feet in diameter made of stones of the same 

 size. This group of three concentric circles we 

 will call M. The line joining the centres of L and 

 M runs in a direction of 29 or 30 west of north 

 and passes through a stone (N) 8 feet high standing 

 on the top of a ridge 2500 feet away. There are 

 two other stones more to the west (O and P) in 

 such a position that the line joining them (41 ° 

 west of north) passes through the centre of M, 

 from which they are distant 860 and 1450 feet 

 respectively. Further, a line through the centre 

 of L and a great standing stone (0) 2480 feet from 

 it in a direction io° east of south passes through 

 the highest point in the district, 1615 feet away 

 and 492 feet in height. 



Mr. Lewis compares this group of monuments 

 with that of Stanton Drew in Somersetshire. In 

 both a line joining the centre of two circles passes 

 through a single stone in a northerly direction, 

 and there is in both a fixed line from the centre
