erected in Ireland. This well was at once identified, as it is the source of a 

 stream which has turned a mill on the site of the ancient one to the present day. 



2. The next grand feature identified was Rath na Riogh, the most impor- 

 tant enclosure on the Hill, which is clearly pointed out by its locality in relation 

 to the Well JVeamhnach. 



3. These two points being ascertained, no doubt remained of the situation 

 of Rath-Laoghaire, which was situated immediately south of Rath na Riogh. 



Having ascertained beyond question these three grand features, the smaller
