The reporter went the other day "a
see wonderful. machine, machius
which u MT only proiigio1s and ter
rible piece Z en1inery, but an allegory
1t Is called a testing machine, and IL il
used TO ascertain tie resisting power Of
various pI1gTislA IL Is not content
/ with finding ont that n beam Of oak, for
instance, Will bcar without breaking q
pressure on 0ne spot Of 100, 600 pounds.
The beam must he utterly crushed each
time tine test - made, and note must be
taken Of the exact weight that lay upon
: ct tho moment Of its final dissolution.
Day after day This great machine heayes
and strains itself and bears down with
'low and awful force upon some tough
team OF block Of wool, and whether the
timber is placed hatwise and needs, say,
but paltry 10 tons to crush it, O.
whether it be placed endwise, like
pillar, anl will hold up twice as much
weight before it cries out and gives up
the ghost 1t must yield just the same
and surrender its pitiful, crushed frame
TO be photographed and studied and
picked to pieces for the benefit of sci.
ence That is all very interesting. you
may say, but it is n mere piece of brute
machinery. Where is the allegory that
you told us OFF That lies in the thing
by the force Of which this monstrous
pressure il txerted. 1t is oil Nothing
but suaye, gentle, yielding oil. the en-
blem OF softness and agreeableness.
There is a certain piston in this
mechanism which, pressing against a
quantity of oil in a confined space, forces
this oil against another iron surface,
which in turn presses forward upon the
timber so that all this crushing power is
exerted by the medium OF nothing but
oil. As you watch the machine, even In
the most exciting moment OF the culmi-
nation Of its crushing force, you can.
not but DO conscious that il IL the oil
that is doing it, The master stands over
his great machine, his pupils grouped
about IL hes down fiat ON its great
back, like "a giant bracing his shoulder
against rock TO push with his feet.
The thing which he is pushing against
is beam OF seasoned oak, about 10
inches square, aud the thing with which
he is pushing Is another and lengthwise
square beam Of oak, tho end Of which is
directly against the side OF the beam 10

uno0nnected with tho machine, but IN

with the throttle valve Of locomotive,
and "a gauge which registers accurately
the pressure that is being eKerted. A
young learner stands at these levers and |
