It will be seen from the cut of our chimney, that it is constructed with a small tube in the center, which extends from below the burner to the top; through this center tube, a current of fresh, warm air is constantly furnished to the flames, which produces at the center of the burner, a most powerful fire, applying it at a point where the greatest possible utilization of the heat is secured.
Through the large openings at the top of the inside perforate, a large proportion of the flame is drawn toward the center of the burner, so that the heat is applied evenly over the bottom of the cooking vessel, thereby securing the greatest amount of benefit from the fuel consumed.
RIGHT CONSTRUCTION.
No. 4.
WRONG CONSTRUCTION.
No. 5.

Reasons Why Preferred.
It has no wick
