A. If the chimney flue can be carried higher than the steeple or hills, no wind can enter the flue.
Q. Why cannot the wind enter a chimney flue, if it be carried up higher than the steeple or hills?
A. Because the reflected wind would strike against the sides of the chimney-flue, and not pass over the opening at all.
Q. In what other cases will a chimney smoke?
A. If both door and chimney be placed on the same side of a room, the chimney will often smoke.
Q. Why will a chimney smoke, if the door and stove are both on the same side?
A. Because when the door is opened, a current of air will blow into the chimney-place, and drive the smoke into the room.
Q. What remedy can be applied to this evil?
A. The door must be set opposite to the chimney, or nearly so; and then the draught from the door will blow the smoke up the chimney, and not into the room.
