used. They are not rectangular ; but were moulded slightly 

 wedge-shaped, so as to fit in as voussoirs in a nearly flat arch. 



In places near Portumna, Eyrecourt, Banagher, &c, in the 

 flats of the Shannon, bricks and draining-tiles have been made, 

 but not of the best class. 



KERRY. 



Yery good Bricks made at Listoivel, for about 20s. per 1000, 

 size 9x4x3, weight 7 lbs. ; fair at Tralee for about 23s. per 1000, 

 9 x 4 J x 2|, weight 7 lbs. On the Coal-measures in the east of the 

 county there are, in places, brick and other clays.

KILDARE. 



The Fuller's Earth at the Hill of Allen was formerly very 

 valuable, but is not now worked. 



At Waterstown, two and a-half miles from Naas, a poor brick ; 

 but the bricks used to build Lord Stafford's ("Black Tom") 

 castle at Figginstown, Co. Kildare, were of excellent quality. 



The Athy stock-bricks are made in the neighbouring country 

 {Kildare and Queen's Co.), and are sent in great quantities by the 

 Grand Canal to Dublin, &c. Prices in Dublin from 30s. to 32s. 

 per 1000, 1000 making about 2\ tons. They are neither pa- 

 nelled nor perforated. They have been largely used in the suburbs 

 of Dublin ; particulary Eathmines and Eathgar. Gruinness's new 

 malthouse and hop store are built of them. 



Facing-bricks, 9 x 4J x 3, were formerly made and brought 

 by Messrs. Webster and Co. to Baggot-street Bridge for the Dublin 

 market. They were a first-class brick ; and the bricklayers state 

 that they find them in the old buildings in splendid condition. 

 They were used in the old Theatre Eoyal. 



The grey-stock, 8J x 3 \ x 2J, is well burned, and suitable for 

 factories and such buildings. Their tenacity exceeds that of any 

 imported bricks. They are very suitable for chimneys ; also for 

 arches and walls where machinery is used. They bond more per- 

 fectly than most other bricks, and are therefore very suitable for 

 being set in blocks built with templates. The engineer of Guinness's 

 Brewery has found that after fifteen years the concrete arches
