which has been attempted. 1t con-
sists Of IS or 100 of the various
parts of Chalmers cars. A dem
onstrator. who accompanies the exhibit,
gives a very comprehensive talk on the
methods Of automobile manufacture, IL
lustrating particularly the methods by
which the cars are tested.
One feature of the exhibit is a set of
scales upon which the demonstrator IL
lustrates the perfect balance of automo-
bile construction, balancing cylinder
against cylinder, connecting rod against
connecting rod, and SO forth The ex-
hibit also includes a very complete set OF
test gauges, which are used in the De-
troit plant.
Some idea Of the wonderful accuracy
of automobile manufacture may be gained
from a recent experience of the demon
strator who accompanies this exhibit. In
explaining the process of using the test
gauges, the demonstrator held in his hand
one of the smaller motor parts which is
tested for an accuracy Of less than one
one-thousandth part of an inch. Having
demonstrated the perfect fit of the gauge,
he held the piece in his hand for less
the gauge would not fit, the heat Of the
hand having expanded the nickel steel
part enough to change its measurement
the infinitesimal degree necessary to make
1t too large for the testing gauge.

Ca, during the week of the Vanderbilt
cup and grand prize races there last
November, when a Victoria model was
called upon to supply lighting power for
train of Pullman coaches.
The railroad company ran number of
