referred to a later date than the 

 plant-bearing beds of inter-basaltic 

 age, which occur at Ballypallady. 

 The Basaltic series of Co. Antrim 

 rests as a whole on the chalk, which 

 is of Upper Cretaceous age, and 

 contains the zone of Bdemnitella 

 mucronata. 



" The facts established by the 

 boring, combined with certain re- 

 lations observable at the surface 

 and hitherto imperfectly under- 

 stood, indicate with a fair amount 

 of certainty that the Tertiary fold- 

 ing and faulting of the district affect 

 equally the Lough Neagh beds and 

 the lavas on which they rest. The 

 earth movements which resulted in 

 this folding and faulting are, for 

 reasons which cannot be entered into 

 here, generally considered to be of 

 Miocene age. The Lough Neagh 

 series is, therefore, presumably pre- 

 Miocene. It is certainly not later 

 than early Miocene. 



" The stratigraphy of the Lough 

 Neagh beds is exhibited in the ac- 

 companying diagram. The main 

 horizons of identifiable plant re- 

 mains occurred in the brown shales 

 or clays between the depths of 881 

 feet and 1,008 feet 7 inches, lying 

 mainly in the upper portions of these 5 



shales. The plant remains in the 

 white clays above and below these 

 beds were for the most part uniden- 

 tifiable, being highly carbonized. 



"From the geological relations Sa.ndEM 

 alone it is impossible to draw any 

 more exact conclusion regarding the
