QUEEN'S COUNTY. 



Potter's Clay has been found in diff erent places, and has been 

 worked a little near Abbeyleix. At Mount mellick a most extensive 

 pottery for coarse ware, such as crocks, tiles, garden-pots, &c, was 

 carried on for a number of years ; these works, in later years, 

 turned out a vast number of drainage-tiles. At Arless, Killeran 

 parish, there was a manufacture of roofing-tiles, formerly exten- 

 sively made to supply the Dublin market, before the great intro- 

 duction of slate into that city. This industry died out entirely in 

 1840. 



Bricks of good quality are made in great quantities in dif- 

 ferent places in the low country west of the Barrow ; those in 

 Graigue, a suburb of Carlow, being intended principally to supply 

 that town; 18s. to 20s. Large quantities are conveyed by the 

 Grand Canal to Dublin, New Eoss, Waterford, and intermediate 

 places. The "Athy brick" has already been mentioned {ante, 

 p. 156). 



At Forest and Clonsast, and in several places near Mount- 

 mellick, a poor, yellowish-red brick. 



Fire-clays. — These have not been utilized {see Kilkenny, 

 ante, p. 157).
