nth" for "north," and this must be right. For, when we read further, 

 we find that Tech \fairisend was north <>\ Nemnach, and Raith Loegniri 

 north of that again; Nemnach must therefore have been south of Raith

 it* relation to the great Raith Rig; and ii" site Bouth of Raith [x>eguiri could 

 be described as being "north-easl of r l|emair." 



Petrie identified Nemnach with a spring that lies on the eastern slope of 



the hill, south of the modem village; tl xcellenl Bource which Bupplies 



the modern village with water It i- just about east-north-east of the 

 principal group of structures on the summit of the ridge. 1 Hi* chief argu- 

 ment for this identification was that "it is tin- source "t .i si nam which

 io tin' time when Petrie wrote. The reference is to the well-known story 

 told in VI) iii 109-120. and also in PD 6 that upon a stream Bowing from 

 nach was erected the first water-mill in Ireland, made by king Corniac 

 for the benefit of his slave-girl Ciarnait, who was un ible owing to physical
