KiNAHAN — On the Leinster and Tipperary Coal Seams. 371 



in my " Geology of Ireland," that in regard to the Co. Tipperary, 

 " In this field every stratum, from the highest in the limestone 

 to the highest of the coal-measures, can be seen and measured." 

 All the strata between the Upper Glengoole coal and the Main 

 coal were hammered and measured by the late Mr. O'Kelly, 

 Mr. Wynne, and myself, in the Glengoole level, while subsequently 

 they were re-measured by O'Kelly. Moreover, there is on the 

 surface a very continuous section, which was carefully examined 

 and measured by O'Kelly and myself, and subsequently by the 

 late Mr. Jukes, accompanied by O'Kelly. I am informed by 

 Mr. Meadows that he not only examined and measured this sec- 

 tion, but also others in the field, and found O'Kelly's measure- 

 ments substantially correct : if anything out, they are a little short 

 of the actual thickness. It may be mentioned that from the 

 measurements given by the Glengoole level, Mr. O'Kelly and 

 myself were able to localize the outcrop of the coal that was 

 afterwards wrought between the Collieries and Killenaule. 



Of the eight coals that appear in Section No. 1, three at 

 least — the Stinking coal, Maker's Vein, and Hanlet/'s Vein — are 

 commercially valueless ; while the total thickness of the measures 

 in which the coals occur is about 1200 feet. 



In the Leinster coal-field there are at least eleven coals and per- 

 haps twelve {Loiver Toivlerton). Of these, the Gale Hill, Moduheagh, 

 Crow, and Jarroio Croiv coals, are commercially valueless ; while the 

 Kingscote or Bullring, the Ward or Foul, and the One-foot coals 

 (irrespective of the Jarroiv Channel) are not of much account ; the 

 more profitable coals being the Moduheagh or Rushes, the Jarrow 

 Channel, portion of the Foot coal, and the old Three-foot coal ; these 

 occurring in a thickness of strata of about 1500 feet. There were 

 also the upper coals in Coolbaun Hill that are now worked out. 



The Sections Nos. 1 and 2 indicate that in the lower portion of 

 the Leinster section there are more coals than in the correspond- 

 ing thickness of the Tipperary section ; also that opposite the 

 portion of the latter, in which thev aluable coals occur, there are 

 no coals of any value in the Leinster section, except the Jarrow 

 Channel, which is not a regular coal, being only an accidental 

 adjunct to the One-foot coal. 



It may be said that as the lower and middle measures of the 

 Tipperary field are about 1500 feet thick, while those of the
