KafId'S Fair Letter.
st Lsnf, No, July SSH, 1904
Editor Notwithstanding the
description of the exhibits in tho
order in which they should come
with reference to location, we shall
take up the Machinery Hall this
time.
A great many people are not
much interested in machinery, and
the name is possibly enough to
keep many away. Yet. all should
at least take a glance at the ex-
hibits, especially at some OF the
engines of enormous size there
represented. The building can
not fail to be attractive to all in
terested in our wonderful improv-
ment in the last twenty-five in all
classes of machinery; and there
are points of interest to all, If the
machinery is made to operate and
the parts explained. For instance,
no one would pass unobserved the
5000 horse power engine and the
dynamo of Allis-Chalmers, Chic
ago, that furnishes the myraids OF
lights used in the illumination of
the buildings at night and for the
transportation of visitors to and
from the fair. To think of an
engine of such magnitude and
power will naturally create an
interest. Almost every type Of
engine is represented in this build
ing.
The four powers, gas, steam,
water and electriclty-and air
ahould be added-are successfully
harnessed and the results shown.
Probably the largest exhibit there
is the Westinghouse. 1t consists
of electrical machinery, mostly
dyuamos and motors. They have
three engines of the same type as
the large one mentioned above, all
in working; order, bat usually only
one IN operation at the time This
one also furnishes some of the
electricity used so extensively in
the fair. A short distance from
these larger engines are smaller
ones, some OF the compound type,
running SO smoothly, and easily
and making so little noise, as to
suggest perpetual melton. Among
the small engines is to be found a
steam turbine acting on the same
principle as the water turbine, and
revolving the dynamo directly at
tached with speed that is rather
marvellous. The idea is good one,
comparatively new, and will be
carried further to affect other
machines, as steamship engines.
Within a large auditorium arrang-
ed for darkening, moving pictures
OF processes in the manufacture OF
their machinery, are given several
times during the day, Al exhibit
that viii DO interesting TO Ms.
sesippMas especially y ftsrs ".

They show three or four sizes OF
their engines, and some saw mill
machinery. While the exhibit
is not as extensive and as imposing
as some in the building, it is very
good of the kind and shows that
we are not wanting in this class of
products. There are many other
machines and devices of interest
throughout the building, too many
for mentioning in this connection.
One machine that particularly at
tracted nay attention was a large
steam forging hammer, a great
labor saving device. Steam IS ap-
piled about the time of the COM
pletion Of the fall of the hammer
and raises it again, to repeat the
process. The working is rapid,
considering the weight raised, and
the work done must be something
enormous.
There is alss an attractive ex-
hibit Of carborunduM, the new
artificial abrosine, that Is fast
s%uperceding the emery wheel for
grinding purposes. The latter Is
q product of nature, at least the
material is the former the product
Of the electrical furnaces III use
at Niagara Falls. Sand, sawdast,
and charcoal, | believe, are mixed
together and put in the furnaces;
the current turned on, and after
being subjected to great heat, the
mixture becomes cerborundum.
Our great wealth is attributable
in large measure to our machines
and we should be interested in
seeing them work. Such an ex
tensive view Of them could not be
gained without much time and
travel otherwise. Here they are
not exactly in a shell, but in a
very small space comparatively.
Yours truly,
