How to circulate the water is still
in disputed question. judging from the
various examples to be seen at the
trlew York auto show. That natural
fcirculatiop without the use of pump
Is growing will probably not be dis
fputed. and examples of 1t are found
In various parts of the Garden, be-
srS employed on the little Brush run
abouts and also on the large Samp-
son touring cars. The simplicity OF
the natural circulation cannot be de-
MED. but it is generally admitted that

eiderably larger pipes should be used

Sampson cars are also found the CEN

seen on a number of other cars.
In the Jackson cars the valves are
arranged in the cylinder heads, which
greatly decrease the amount of cyl
1nder wall and consequently the
amount of heat loss, which arrange
1rent is quite common on many other
cars A noticeable feature of this ar
rangement on the Jacksons is the L
headed valve supporting brackets
which carry the valve operating lev
ers partly enclosed and thus protect
ed from dirt and grit. A somewhat
similar arrangement is used on the
AutOcar where one end of the Operat-
ing lever is inside the valve housing
in a very neat and clean manner. An
other feature of such enclosing is the
1essened noise accompanying the en-
gine's operation. A noticeable feature
of the Jackson engine is the direct
connected manifold which employs
four long members each reaching al
most directly from the carburetor to
its respective cylinder.
In the Pope-HartfOrd cars one fea-
ture to attract attention is the quite
wide face of the flywheel. This not
only is very efficient because it car
r-ies a great portion of the weight
at the greatest possible radius dis
lance from the crank shaft but also
because 1t permits the use of very
large wide faced cone clutch. An
other feature IS the perfect flexibility
provided by the use of not only two
ginlbal joints in the propeller shaft,
but also the use of a third one be-
tween the. transmission and the
clutches, all of large size and well
worked out Another noticeable fea-
ture is the tall engine. indicating long
connecting rods and long engine
strokes
In the Pullman cars one distinctive
feature is the combination separate
