J. McC. Meadows — On the Leinster Coal-field. 105 



relative positions and characters of the seams of both districts may be 

 looked for. 



The Slievardagh field has the advantage of regularity in its strati- 

 fication, and the following is a section of the deepest portion of the 

 field near its centre, at the Earlshill Colliery : — ^

As in this section there is an upper seam for which in the Leinster 

 field there is a deficiency of strata over the Peacock Coal, the sections 

 of the two districts will be best contrasted in ascending order from 

 the lowest workable seam in each. 



It is submitted that the No. 1 and No. 2 Glengoole seams of 

 Slievardagh represent the Eossmore Foot Coal and the Eushes seam of 

 Leinster, and that Maher's Vein and the Main Coal of Earlshill re- 

 present the Jarrow seam and the three-feet seam of the Castlecomer 

 field. The thickness of strata between the No. 2 Glengoole seam 

 and Maher's Vein points to the distance, which is also felt to be con- 

 siderable, between the Eushes seam and the Jarrow Coal. 



When the sections are examined in detail, and the relative quali- 

 ties of the seams compared by those with practical knowledge of both 

 districts, other parallels, unnecessary here to refer to, will be ob- 

 served. Amongst them, however, may be mentioned as common to 

 both districts the character of the coal of the two lower workable 

 seams in which Culm or fine coal occurs, and the preponderance of 

 hard coal in the upper seams.^ 



Present Cendition. 



Upon a recent visit by the writer, the several mining works, at 

 present raising coal in the district, were found to be as follows : 



Upon portions of the upper seams, — Pits on the Hill of Coolbane. 



Upon the Jarrow seam, — Jari'ow Pits Nos. 1 and 2, the Eock 

 Colliery, Monteen Colliery, Hollypark Pits. 



Upon the lower seams, — Skehana Colliery, Bally lehane, Tolerton, 

 Eossmore, and Eeevanagh.
