in automobile engineering, in original
research connected with raw and
finished material, in the establish
ment and intelligent use of mechan-
ical and material standards, is with
out parallel and we'll known The
association members have been quick
to draw to their logical and accurate
conclusion the original data on va
ious engineering subjects jointly and
severally submitted and discussed at
their periodical meetings within the
last several years, Many of the MEM
bers now maintain complete testing
laboratories of their own.
Perhaps the two things accom-
plished by the association, which are
of particular interest to the user, are
the raising of the standard of design
and construction, and the standard
ization of parts. During the past
four years new standards for the var
ious metals used in automobile parts
have been worked out and annually
compiled, resulting in the use by as

this is seen in the record of what
the association cars have done in or
binary touring service and in around
the-world international racing, en-
durance, transcontinental, reliability,
and efficiency contests. The ripe ex-
perience of able engineers, exhaustive
special experiments and continued
practice have made this possible.
Users are thereby assured that they
are thereby given the full benefit of
the progress in the art, in material
and in production, as shown in de-
sign, quality and price.
The association members have APP
preciated that properly heat-treating
special metals is of equal or greater
Importance than the character of the
material as judged by chemical analy-
sis. This is a great lesson.
Alloys and Their Use.
AS an authority has said, various
treatments of the metal have proved
successful to greater or less degree.
The case-hardening process has been
worked out into practical usefulness.
The result is the accomplishment of
the chief aim of the builder of high
grade cars-reliability and long life,
combined with concentration into
small space of mechanism conveying
large units of power.
The chemist is playing an i'm
portant part in this work, not only
in discovering alloys which give the
desired results, but in constantly test
ing steel that enters into the con-
struction of the working parts that
have to withstand severe strains. In
some cases it is not considered enough
to analyze by sample; each individual
piece must be tested and rejected if
not within the required limits. At
times not only the surface of each
bar. but the core, as well, is analysed,
to determine the degree of segrega-
ton existing in some alloys. The
I Cost is greater as compared with the
use of ordinary steels, but those who
value their reputation consider this
does not offset dependability.

parts of an automobile are subjected

mining by dynamic as we'll as static
test the enduring properties of a
given metal For example, a piece
of metal is driven in the laboratory
under load hundreds of millions of
revolutions to learn it's life under
different conditions closely analogous
to those metals experience in an au-
tomobile running for tens of thou
sands of miles on all kinds of roads
and vicissitudes of driving.
American-Built Automobiles.
For perfection of design appropri-
ate to the loaG and conditions of en-
ployment, for excellence of material
and sound, accurate workmanship
American-built automobiles cannot be
beaten anywhere in the world. For
efficiency and aggressiveness, Ameri-
can mechanics are the best. Ameri-
can machine-tools, it is generally ac-
knowledged, lead the world. One of
the French pioneer automobile MAX
ers said some years ago that If it had
not been for the fact that American
houses were in position to supply
certain types of lathes, drilling-ma-
chimes, milling-machines, gear-cutting
appliances and other intricate pieces
of mechanism, when the automobile
movement began to expand, popular
vehicle could never have been consid-
cred by the makers, and all classes
of automobiles would necessarily
have remained at extravagant prices.
This condition of European automo-
bile makers turning to America for
modern appliances and new, ingenious
machines, which make possible pro-
ducing higher grade automobiles at
less cost, remains to-day.
The recently developed automobile
is, as mechanical production, far
superior to anything that is a means
of locomotion. Compare it with the
railway locomotive, upon which the
best engineering skill has been Law
ished for seventy-five years; compare
the relative conditions, under which
tbs two run, and remember the re-
spective care and adjustment given
them. The platform Of the modern
motor-car maker can be said to be:
To produce car that meets the peo-
pies needs, with an appearance which
strikes their fancy, whose operation
and riding qualities are so easy as to
be pleasure. and whose first cost
and maintenance are SO low that it
is an inexpensive luxury to some and
