MECHANISM VS.. BRAINS.
Substitutes Found and Patented Many
Times Each Year.

From the corn miller's little bell that
sets up a fussy tinkling the moment the
hopper runs empty. up to the calculating
machines that are now to be found In banks
and insurance offices, clearing houses and
observatories. there are so many mechan-
ical substitutes for brain workers that 1t Is
difficult at times to realize that 1t is after
all, only mechanism and not intelligence
that Is being evolved" said an employe at
the patent office to a Star reporter today.
Some of the touches of what. for con-
yenience, we may call mechanical 1nteili-
gence to be met with in various odd corners
of the Industrial and commercial world are
really quite amusing, and they have their
prototype in shat little bell of the old wind
mill.

YOU cannot help laughing and you would

quite practical to make it do so.
1.-The machine by which railway tlckets
are printed gives another amusing little
show of intelligence or what looks to be
very like it. Railway tickets are not as
might be supposed printed in large sheets
and afterward cut UP. The cardboard Is cut
into tickets first and they are printed one
by one afterward.
The little blank cards are put in a pile
in a kind Of perpendicular spout, and the
machine slips bit of metal underneath the
bottom of the spout and pushes out the
lowest ticket in the pile to be printed and
consecutively numbered.
ut Is of no use trying to print bad
ticket. The machine finds out an imperfect
blank in an instant, and fatty refuses to
have anything to do with 1t.
These are simple instances of a good
imitation of watchfulness and discrimina-
ton: indeed, the latter looks almost like
conscientious care. They afford a droll
suggestion of the trained intelligence Of the
learned pig or the performing dog; and we
may find various degrees of the same. At
the United States mint they have Weighing
machines for coins to which it is difficult
to deny a very acute intelligence. The mint
apparatus is more remarkable of the two.
THE new coins at the minis, however,
are sometimes a trife over weight, while
sometimes of course, they under, so
it is necessary to sort them out in three
categories-light. heavy and good. This del
icate business is done with unerring pre-
cision by long row of wonderfully clever
little machines.
Into these machines single piles of shin
ing new coins are put, and quite auto
matically the mechanism takes each coin,
puts it into the scale and in a fraction
over two seconds-at the rate of twenty
five a minuIe-weighs it. If the coin is
light the machine shoots 1t into It's proper
receptacle; If heavy into another, and IL 1t
is of correct weight or with a margin as
they call it. 1t is pushed into third re-
