Kane — Additional Researches on BlacJc Pig^s Dyke. • 545 



coiueidenee that the officer iu charge of the Ordnance Survey, when plotting 

 the Black Pig's Dyke between Lough MacXean and Loiigh Melvin at T.attone 

 in Leitrim, found that the almost obliterated remains of the trenches in that 

 district went by the name of the " Great Man's Track " or path. See my 

 former paper, p. 321. For it is quite possible to hold that the Dorsey might 

 be the enclosure which is described as in the plain of Murthemne,' since 

 that district has been described as "extending from the Cualgne Mountains 

 to the Boyne," and certainly it lay upon its border. The existence of the 

 " Great Ditch " running to the west from the Dorsey in Iw 07 further supports 

 such a hypothesis, and the standing-stone in the dun might be the pillar- 

 stone to which Cuchulain is said to have tied himself when wounded. 

 Nevertheless, an examination of the text of certain Irish mss. appears rather 

 to confirm the local tradition at Eathiddy, near the village of Louth, that 

 that locality was the one to which the ancient authorities refer. There, 

 however, no trace of any " rampart " is extant. In the Louth Archfeologieal 

 Journal of 1907, an interesting paper by Mr. Henry Morris describes the 

 locality referred to. Again, in the Mesca Uladh (p. 15) we read that 

 Cuchulain, " starting from near Coleraiae, drove to the plain of Ardmagh, then 

 to Slieve Fuait, and into the watchman's ford (ac n^s ■poii6.i]ie), to Portnoth 

 of Cuchulain, into the plain of Murtliemne," &e. 



In the Glenmasan MS. of the Tain bo Cualgne, in the passage describing 

 the journey of Deirdre and the sons of Uisnech from the Dun of Borrach in 

 the north of Antrim, we find the words : " After that, they proceeded to 

 Finncarn of the Watching on Slieve Fuaid " (Finncarn na Foraire ar Sliab 

 Fuait), and then to Emain Macha. This was after Deirdre had vainly 

 implored her companions to ask the protection of Cuchulain at Dun Dealgan. 

 Before proceeding to describe the discovery of two other lines of frontier it is 

 necessary to correct certain errors which crept into my former paper, and 

 confused its accompanying map, also to give the results of an expedition 

 of research to identify the line between PLOOsky and Sgairbh Uaehterach 

 (Ballinamore) in accordance with the corrected indications furnished by 

 Father Walsh's revision of the original text. I correctly indicated Mohill as 

 the next station to Eoosky, but set down the line from Mohill popularly 

 supposed t-o run thence to Lough Gowna, Granard, and Lough Kinale, as 

 forming a part thereof. In reality these entrenchments from Lough Gowna 

 to Lough Kinale appear to belong to another frontier hereafter to be described. - 

 I fell into a further error bv taking- for g-ranted that the Eiver Shannon from 



' Ex. gr. in the Book of Leinster, 77 a 7, a ford, named Atli na Ferta, is stated to be 

 in Slieve Fuad, though elsewhere described as in Blagh Murthemne.
