Glass. — At Melitia, westward of Shillelagh, and about two 

 miles from the ancient church of Aughowle, there is the site of an 

 ancient glass-house, to which attention has recently been directed 

 by the Eev. J. F. M. Ffrench {Jour. Roy. Hist. Arch. Ass., Ire., 

 vol. vii., 4th ser., p. 420). In the neighbourhood there is a sand 

 which the glass- workers of Dublin state, " if ground down, it 

 ought to be a suitable sand." Glass seems also to have been 

 manufactured at the Chamney Iron Furnace, Shillelagh, as some 

 years ago, when removing part of the old ruins, a quantity of glass 

 slag was found. 



In the townland of Ballymanus, westward of Aughrim railway 

 station, there is a dyke of fine white sand, evidently a decomposed 

 felsitic rock. This has been submitted to the glassmakers at 

 Bingsend, Co. Dublin, who state it is too clayey for clear glass, 

 but ought to be excellent for black glass. To meet the Dublin 

 market it would have to be delivered at about 3s. per ton.
