KiNAHAN — On the Leinster and Tipperary Coal Seams. 367 



northward, in the Bushes CoUierj, there does not appear to be any 

 representation of it ; but immediately north of Towlerton, in the 

 townland of Woodlands, or Newtown Harpole, two coals are re- 

 corded ; while it was also found in some of the pits in Towlerton ; 

 but in other pits, sunk to search for it, it was not found. Possibly 

 here, as at Coorlaghan, there may be in places a " splice," being 

 portions of the one bed with a "horse" between them, or, as sug- 

 gested by B, B. Edge, there may be an overlap, as found in the 

 Doonane Colliery, In the Newtown Harpole bore-hole, and in 

 one pit in Towlerton, there was about 50 feet of strata between the 

 two coals ; elsewhere, however, in Towlerton, it is said to have 

 risen up towards the Old Toiclerton coal. 



Since the year 1859 the continuous workings on the Jarrow 

 Channel have proved it to be a rather remarkable accumulation. In 

 1859 it was generally supposed to have some sort of a connexion 

 with the One-foot coal, but the relations between the two were quite 

 obscure ; some ten or more years afterwards, when a pit had been 

 sunk and workings commenced on the portion of the channel under 

 the Clogh royalty, the proprietors ran a drive northward, for 680 

 yards, which proved that the Jarrow coal lay in a washout or 

 channel ; the coal at the margin of the channel joining into the One- 

 foot coal. The accompanying section, PI, XIV., fig, 1, for which I 

 am indebted to Mr, Meadows, is a tracing from the working plan. 

 From this we learn that for 264 yards the floor of the coal rose ; while 

 on the brow of the rise it joined into the One-foot coal, " a regular 

 coal " on a " fire-clay and seat ; " while under the coal of the 

 channel " there is no fire-clay or seat, there being only a sort of 

 shaly seam between it and the country rocks," {See note at end.) 



The washout, in which the Jarrow Channel occurs, is both im- 

 portant and peculiar; 



If the great N.E, and S.W. Coolbaun fault be taken as a base, 

 to the northward of it, this washout forms a more or less regular 

 horse-shoe, extending from the Geneva Colliery, on the east, 

 northward along the valley of the Dinan to Clogh, and thence 

 westward to Massford, and southward to Coolbaun. South of the 

 N.E. and S.W. Coolbaun fault the exact position of the channel 

 lias not been proved, as the only workings are to the eastward, at 

 Monteen and Kilgorey, and to the westward, at the Eock Colliery 

 (Augharenagh) , places lying nearly east and west of each other.
