The Co. of Dublin stocks that were used when building the Theatre Eoyal, Poolbeg- 

 street, were so good, that after it was burned, and when the Leinster Hall was being 

 built on its site, the old bricks were so firm and intact that most of them were used in the 

 new building. Co. Dublin stocks, at 45s., dropped out of the market through the importa- 

 tion of the Cardigan brick at 39s. The latter is an inferior article, as the Co. Dublin 

 brick is probably worth 5s. per 1000 more than the Cardigan red stock. The supply is 

 now limited in consequence of their being undersold by the Kingscourt and English 

 bricks. The Dublin stock is neither panelled nor perforated.] 



Mount Argus, Harold's Cross. — The bricks made here are red 

 and grey in colour, 9 x 4j x 2f , perforated, price 38s. per 1000. 

 They are good and well burnt, but contain lime. The works have 

 been open only a few years, yet they have great custom. These 

 bricks have been used in the buildings of the Eoyal University, 

 and in many others for front work.

[The brick trade, like all other trades, suffered during the general depression which 

 affected the country in 1852, and subsequent years ; and before it could recover, foreign 

 bricks had in a great measure taken the place of the Irish, principally Cardigan and 

 Bridgewater ; the latter commenced to be run on about 25 years ago. The Kingscourt 

 brick is a first-class article, equal to the Bridgewater, and of a better colour ; it has 

 rapidly made its way.
