OF THE MANAGEMENT OF FIRES IN 

 CLOSED FIRE-PLACES. 



Necessity of keeping the Doors of closed Fire-places well 

 closed, and of regulating the Air that is admitted 

 into them. Account of some Experiments which 

 showed in a striking Manner the very great Impor- 

 tance of those Precautions. A Method is proposed for 

 preventing the Passage of cold Air into the large Fire- 

 places of Brewhouse Boilers, Distillers' Coppers, 

 Steam-Engine Boilers, etc., while they are feeding 

 with Coals. Bad Consequences which result from 

 overloading closed Fire-places with Fuel. Compu- 

 tations which show in a striking Manner the vast 

 Advantages that will be derived from the Use of proper 

 Care and Attention in the Management of Fire, and 

 in the Direction and Economy of the Heat which 

 results from the Combustion of Fuel. 



THOUGH I have already mentioned, more than 

 once, the necessity of preventing the entrance of 

 air into a closed fire-place by any other passage than 

 by the register of the ash-pit door, and have strongly 

 recommended the keeping of the door of the fire-place 

 constantly closed ; yet, as I have since found that those 

 precautions are even of more importance than I had
