southward from Corker House to join the open river. 

 This must come from the Boleyneendorrisb river, as 

 when there is a freshet in that river, and none in 

 the Gort river, the river at Coole becomes quite 

 muddy; but if there is a flood in the Gort river, 

 a stream flows from Coole up this subterranean 

 passage towards Corker House. Where the Gort 

 river takes the ground, on the S.E. of Kiltartan, 

 there are the traces of two older channels at higher 

 levels than that through which the water during 

 the dry season now finds its exit. The highest level 

 is now entirely stopped, and a stream flows back 

 along the old course down to the present river. 

 The middle level, during floods, is still used, and 

 the water rushing down into the subterranean 

 channel below forms a small whirlpool. 



A very large turlough is formed in connection 

 with Coole Lough. During the dry weather the 

 water on every side flows into this lough ; but when 

 the floods arise, the subterranean passages are not 

 large enough to carry off all the water, which 

 therefore fills the lough and overflows to the south, 

 where it forms a most extensive turlough in the 

 neighbourhood of the Newcastle racecourse, which 

 lies to the KW. of Gort. 



On the 12th October 1862, cricket was played on 

 the racecourse of Newcastle, and there was scarcely 

 any water in the streams, but the succeeding week
