SoLLAS — A Map to shoiv the Distrihution of Eskers in Ireland. 



about 3 miles from its origin, it receives a tributary which arises close to the 

 Moyne cliain on the east, and immediately south of Kihialag, where it enters 

 Loughapollboy bog, it is definitely joined by the Moyne chain. Past Kihialag 

 it becomes a double chain enclosing an elongated depression, and then unites with 

 the Tuam chain. 



The next Table shows the changes which this esker chain undergoes in eleva- 

 tion above the sea, and in its own height, as we proceed along it nortliwards : — 



5. — The Moyne chain. — It is difficult to determine the commencement of this 

 chain (fig. 2) on the south. It may begin with the isolated esker near Ballyna- 

 park, or possibly with that of Lackaghbeg, 5 miles further to the south-west ; a 

 cap about 3 miles long separates the Ballynapark esker from another isolated 

 rido-e, running from west to east, on which Moyne House stands ; and another 

 o-ap of about one mile intervenes between this and the main part of the chain, 

 which runs for the next 8 miles of its course almost continuously ; and though it 

 retains at first, and for a short distance, the west to east direction of the more 

 broken ridges, it soon turns towards the north-east, and finally due north. For 

 the last 7 miles of its course the chain is very much interrupted, the gaps being 

 much longer than the ridges. On reference to the map it will be seen that the 

 height of this chain, also, above sea-level, increases as we follow it from south to 

 north. [Mem. — In fig. 2, "Lackaghbeg" should be "Ballynapark." Lackaghbeg 

 lies a little outside the southern boundary of this map.) 



6. The Newtown-Bellew chain. — Where the Mo}ne chain bends round from a 

 north-eastward to a due northward direction, it receives a tributary (fig. 2) 

 which may have been fed by the same streams that deposited three parallel eskers, 

 which lie not far from it on the S.E., and which trend from S.S.W. to N.N.E. 



Still further to the south many scattered eskers occur, some of which may be 

 brought into connection witli these just mentioned. They are diflicult to classify, 

 but may be tentatively arranged as follows : —
