several   months.
This ' difference  in
their   operation    is
due to this principle.
Brick stoves now
in use require  the cold air to abstract heat from the bricks comprising the flues in the ovens, after the combustible or heating gases have all  been   shut  off, and   in   the  " iron stoves ''   by reason of   the   iron   pipes or   flues    through which the cold air passes, being separated from     union with the gases; hence the iron stove can run   steadily, whereas     the1 brick   stove

HOT, which allows iron to be made more cheaply than where a temperature no higher than 1,100 degrees F. can be created, as with iron stoves. A further reason for this displacement is that the brick stove is less expensive, in matters pertaining to repairs and "shut-downs," to keep a furnace naming steadily, also in giving more K;IS for use under boilers, etc. than iron stoves.
