the heat. They also feature special
rotable dedectors which permit direct
ing the heat in any way most con-
venient to the occupants Of the car or
most efficient. There have been some
ingenious methods employed to effect
this detection, even to the simple
process Of directing the heat to the
floor boards, where it IS distributed by
reflection.
Hot-air heaters Of the larger type are
more effective If installed In the ton
neau rather than in the driving COM
partment. BY this arrangement there Is
suficient heat for both those sitting In
the rear and those on the driving seat.
The reverse Is preferable in the case of
the water heater. but 1t Is important to
direct the heat upward If 1t is to curve
down from the roof of the car into the
tonneau to warm the rear-seat pas

The shorter the connections for Q
water heater the less the loss of heat
through conductivity. This objection
can be overcome. however, by sufficient
insulation, but this adds to the expense.
There Is an advantage In shorter con-
nections for hot-air heaters in the fact
that these connections tend to rot out
the expense of replacement is not great.
1t Is not generally known that the use
Of hot-air heater has much to do with
the life of the heater unit which con-
meets with the exhaust pipe.
Important Improvements.
There have been important improve
ments in heaters Of this type in the
past year, however, so that units are
less affected by condensation. Joints
are proof against gas leakage and the
air that reaches the cars interior Is in
many cases purer than that found In
cars heated by the principle Of rewarm.

With air heaters 1t is often a uues-
ton as to where the air intake should
be located. The older plan Is to locate
the intake funnel directly in back OF
the radiator. With the use Of shutters
which often remain closed, however,
care must be exercised In such installa-
ton to make sure there is no leakage Of
gases from the oil pipe or the breather
tube OF the engine. With such installa-
ton the heater should be shut of when
trailing behind motor bus or truck. A
newer plan Is to draw the air from the
'front.' compartment by means Of a fan.
Th1S improves circulation of heat
throughout the entire car, but when
used there should be some windows open
to keep the air from going stale. Loca.
ton Of the air funnel for the air heater
behind the fan will have much to do
with the amount of heat obtained In
the car. A little experimenting will soon
show the correct position for maximum
results. If the funnel Is placed too near
the blades there will be an annoying
roar at higher speeds.
In using a water heater care should
be taken not to allow the motor blower
to operate when the car is parked.
Many batteries have mysteriously run
down overnight because the motors have
operated So quietly. It should, moreover.
be apparent that q cheap motor or a
cheap radiator core for the heater Is
