566 Of Chimney Fireplaces. 



level of the upper bar of the grate, this necessarily 

 throws the fire very far into the room. This tends to 

 bring both smoke and dust into the room, not only be- 

 cause it brings the fire too far forward, but also because 

 it occasions the air of the room, that slips in by the 

 sides of the covings, to get behind the current of smoke 

 that rises perpendicularly from the fire, which air fre-

 strike against the mantle. This is a great fault, and I 

 am sorry to say that I have found it very common in 

 many parts of England, where attempts have been made 

 to introduce the fireplaces I have recommended. Where 

 grates with sloping backs are used in fitting up these fire- 

 places, these backs must either be taken quite away or 

 bricked up, and the new back part, or back wall of the 

 fireplace, must be made to serve as a back for the grate, 

 against which the burning fuel is laid. 



As I am giving an account of the mistakes that have 

 been made by some of those who have been employed 

 in fitting up chimney fireplaces on the principles I have 

 publicly recommended, it will naturally be expected that 

 I should take some notice of those numerous improve- 

 ments that have been announced to the public, said to 

 have been made in stoves, grates, etc., to which adver-

 my name. As I am" extremely anxious not to injure 

 any man, either in his reputation for ingenuity, or in 

 his trade, or in any other way, I shall not say one word 

 more on this subject than what I feel it to be my duty 

 to the public to declare, namely, that I am not the in- 

 ventor of any of those stoves or grates that have been 

 offered to the public for sale under my name. 



Having mentioned the inconveniences that sometimes
