IMPROVEMENT IN BRICKS. £55 



that my opinion coincides with yours, as to their advantage, 

 in new chimnies, which are intended to be built against old 

 walls. In constructing a new chimney it is generally consi- 

 dered absolutely necessary, that the same should be worked 

 up close to the old wall, but completely unconnected, in or- 

 der that it might settle from the old ; in this case, it is very 

 desirable to make the back of the chimney as thin as possible, 

 that it may project as little as convenient ; and in building 

 piers, particularly small ones, either for gate-ways or fronts 

 of houses, where there are many bricks, and in the present 

 mode, which is so frequently adopted, of two inch recesses at 

 the exterior of the windows, your closures would be much 

 preferable even in appearance to a brick which has been cut 

 with a trowel, with the surface of course defaced. 



Closure bricks might be adopted as a cheap and useful Drains, 

 drain by a common brick flat, with two closures laid on the 

 same two inches asunder, or four inches, and reversed. 



Your closures would be useful in all kinds of ornamental Ornamental 

 brickwork. work - 



Two inches is a very desirable brick, but most times Two inch 

 avoided in consequence of the waste in cutting common ^ ks desiia * 

 bricks, and difficulty in producing a smooth face, which 

 would be completely obviated by the introduction of closure 



bricks.

Letter from Mr, Benjamin Garroway, to Mr, Stephens. 



SIR, 



I am of opinion, that, if closures were made for general Farther re- 

 use, two and a half per cent would be saved in brickwork of mar ^ s " 

 small piers, flues of chimneys, or where there are any bricks 

 in ornamental works. Common bricks frequently will not 

 cut more than one closure; and if your bricks were to be al- 

 ways had, they would be much more useful. 

 I remain, sir, 



Your humble servant, 

 Ruscombe, BENJAMIN GARROWAY.
