SoLLAS — A Map to show the Distribution of EsJcers in Ireland. 809 



7. The Kilcornan chain. — Near the mouth of the Clarin river, which opens 

 into Galway bay, is a single chain of eskers which runs towards the north-east up 

 the Clarin valley, past Kilcornan, towards Greethill. This may possibly have 

 belonged to the same system of drainage as that of the chains already described, 

 further to the north ; but in the absence of evidence it is impossible to speak more 

 definitely. 



8. The Athenry chain. — This consists of two branches, the Greethill and the 

 Loughan chains, which unite about one mile north-east of Athenry. The 

 Loughan chain is a complicated group of parallel ridges receiving short 

 tributaries. 



9. The Monivea chain. — West and north of Athenry a much interrupted and 

 multiple chain runs from the south-west towards Menlough, on the north-east, 

 receiving south of Monivea a west-to-east tributary, the Knockbrack chain. On 

 the west of Menlough a more or less parallel chain runs from Ryehill past Carbally 

 Castle. 



In addition to the foregoing, several isolated groups of eskers are to be seen in 

 this district, as for instance those of Cloghmoyle Castle and of Pollsillagh. 



10. The Gortachalla chain. — About 11 miles north-west of Galway town, on the 

 west of Lough Corrib, a chain of eskers, about 4i miles in length, runs almost due 

 east, passing north of Gortachalla Lough. There is a bare possibility that this 

 may belong to the Ballyhaunis system. 



The System of the Midlands. 



This great and complicated system may be divided into four subordinate 

 systems ; these are : — 



I. System of Clara. III. System of Edenderry. 



II. „ Parsonstown. IV. ,, Trim. 



I. The System op Clara. — This consists of several subsidiary and three main 

 chains, which run from west to east, converging eastwards, to unite near Judge- 

 ville, about 10 miles east of Clara. They are shown in detail on sheets 97, 98, 

 99, 107* 108, 109 of the one-inch map of the Geological Survey, and are described 

 in the corresponding Memoirs by Messrs. J. O'Kelly, F. J. Foot, G. H. Kinahan, 

 and R. G. Symes. 



Beginning on the north, and proceeding southwards, these chains are as 

 follows : — 



i. Chain of Newtown-Loe (5 miles south-west of Lough Ennellj. 

 ii. ,, Seven Churches (Clonmacnois). 

 iii. ,, Ballyduff (passing about 1^ miles north of Tullamore).
