 door being closed, none can pass through it into the 

 fire-place, and the fire-place door may be left open 

 without the smallest inconvenience; and the person 

 who tends the fire may take up as much time as he

 little or no derangement of the fire or loss of heat will 

 result from these operations. The fire will continue

 fire-place door was opened ; and those immense clouds 

 of dense smoke which, to the annoyance of the whole 

 neighbourhood, are now thrown out of the chimneys of 

 all great breweries, distilleries, steam-engines, etc., as

 for immediate use may be again completed. 



If the flame from the fire-place should be found to

 hole might be furnished with a register. 



But it is not merely through the opening by which 

 the fuel is introduced that cold air furtively finds its 

 way into closed fire-places. If frequently enters in 

 much too large quantities by the ash-pit door-way, and, 

 rushing up between the bars of the grate and mixing 

 with the flame, serves to diminish instead of increasing
