not only counted just so much In the
Stevens Duryea idea of building Il car
light and strong, but 1t made the en-
CINE much more quickly accelerated
and more easily and promptly con-
trolied. Nowadays most fine cars are
built with six-cylinder engines, includ-
ing those whose Akers laughed the
hardest at Duryea half dozen years
ago.

six produces the same smooth, quiet
action.

Presidents Sister Buys Car.
Mrs. Frank L; Perrin. OF Cincinnati,
SISTER of President Taft. has just
bought six-cylinder ALEC touring
car. Mrs. Perrin first was attracted
by the car. while visiting the automo-

Accuracy Of Construction.
"One hears q great deal about the
accuracy of construction OF automo-
tile parts said Lee A. Folger. local
representative OF the Chalmers Motor
Company. I'm the Chalmers factory
are some striking demonstrations OF
this accuracy
"A single instance will prove the
point. An inspector was recently
testing wrist pins which are a part
OF the piston assembly. In this work
is used test gauge for the diameter
Of the pins. which allows a variation
OF little less than nothing So ac-
curate is the machining of this part
that the heat of the hand. as one
holds q wrist pin. will expand the
metal SO that the gauge will not fit.
This does not sound plausible
even. but II Is an actual fact. which
's demonstrated every day. The
Chalmers inspectors cannot use this
wonderful accurate gauge Il they hold
the wrist pin to be tested. in the hand
for. say, ten seconds.
When one considers that this same
degree of accuracy is maintained
throughout the car. one has ready
explanation of the endurance and
smoothncss of the we'll constructed
automobile"
