that are hung to the posts that sup
port the plate-beam iron tracks o.
which the derrick is run. Most of tn
machinery can be seen in operation
from time to time.
When one sees these myriad ma
chimes, belted, or in motion, he will
enquire what the power is. 1t is boil
steam and electricity; steam prima
rily, which operates no less than 8;
engines, and steam that propels the
great engines, which operate the dy-
namos to generate electricity. To get
an idea of the immensely of the boiler
apparatus we will step across to the
south side of the building and see the
boiler room. Here, stretched along
in straight line 70 more than forty
rods, with nearly uniform fronts, is a
line of boilers, put in by different MAX
ers to be a part Of the great show of
the Exposition. There are fifty two
boilers, and they will develop over
900 horse power. The fuel used is
crude petroleum; it is stated that the
oil comes in the great pipe oil-line
which runs from Indiana to Chicago.
The oil is blown into the boilers with
steam jet, ignited, creating intense
heat. There is no need of coal, and
everything about the boilers seemsas
neat as parlor.
Alongside the boiler room is the
main building. A very large space is
given to engines and dynamos, there
being no less than 40 of the latter,
which in turn give power to many
power dynamos and furnish light for
the buildings and grounds, a myriad
lights in all. At the time of the Cen
tennial exhibition the great Corliss
engine with it's big cylinders, great
walking beam, it's complicated valve
gearing and large driving wheel was
the wonder of the Fair, if not of the
world. It was a machine of 1 400 horse
power; but the engine here with the
great 30-foot fly wheel, which looks
not much larger than several others
that may be found near it, has a rated
power of 2, 900 Ell. P. and can develop
much more power. These figures are
enormous and the average reader will
not realize what tremendous power
it is. Imagine double line Of horses
along for more than mile
and third, all hitched to some pom
derous load, and remember that this
would only equal the power of the
great E. P. Allis engine that is steadi-
ly, and almost without noise, doing
a work equivalent to the horses The
engine sets on the floor and occupies
with the drive wheel a space IL feet
wide by IS feet in length. The engine
runs the Westinghouse lighting plant
which the Exposition people use in
lighting the great works of the
grounds. 1t runs two immense dyna-
mos, requiring the strength of two
thick leather belts that are six feet
n width. Close about this large en-
CINE are several others Of not much
smaller capacity all attached to dyna-
no apparatus. We were especially in
erested in the operation of several
engines of great power which were
attached to large dynamos built up on
he crank shafts of the engines. These
- machines were speeded at great
feiocity and ran as still and with as
title jar as an ordinar ten horse pow
n engine. They are a wonderful
,iece of mechanism. The Russell

lave very large exhibit Of this sort
If machinery. It will be remember
ID by many in this vicinity that the
2ussells, who are among the largest
Of agricultural and en-
CINE machinery in the West, started
,ut as poor boys from the town of Sui
Jon forty or fifty years ago and have
grown up with the West. There are
'ngines Of many patterns and by diff
erent makers. Here may be seen the
ripple and quadruple expansion en-
zines, machines in which the steam at
he highest pressure enters the first
CYLINDER, and exhausts alta lower pres
ure into the second, third for+f6urth
cylinder at diminishing pressure, is es-
aping at a pressure SO low that no
'erceptible power is lost. The object
f this complication is economy in
uel. The smallest thing in the engine
me is what is called the Golden
