CONSERVING GAS.--According to authoritative information, [Footnote
8: United States Fuel Administration Bulletin, "Use and Conservation of
Natural Gas"] "the demands for natural gas are now greater than the
available supply. Food and trees can be grown. Water supplies are
constantly replenished by nature, but there is no regeneration in natural
gas." It is thought that natural gas forms so slowly that millions of
years will be required to make the present concentrated supply. As far as
we are concerned, when the present supply is used up, it is gone forever.
Since natural gas is a most efficient fuel, every housekeeper and
householder should feel obligated to waste none of it. Suggestions for
conserving gas follow:

(1) See that the mixer is properly adjusted so that the flame is light
blue in color.

(2) In selecting a gas stove, see that the burner is so located that the
cooking surface is the correct distance above the burner. The tip of the
flame should touch the bottom of the utensil. If it is necessary to have a
long flame in order to bring this about, there is considerable waste of
gas.

(3) If the flame is long, the gas pressure is greater than necessary.
Regulate the gas pressure by adjusting the valve in the supply pipe. A
short flame will save gas and produce satisfactory results, provided the
cooking surface is the proper distance above the burner.

(4) After the contents of a cooking utensil boils, turn the gas cock so
that only "gentle" boiling takes place. A food becomes no hotter in
