HGE LIMIT ON CHILDREN.
None Over Fifteen Years Old to BE
Admitted Free to State Fair.


culture yesterday morning it was deter
mined to place the age limit of fifteen
years upon the children that are admitted
to the State fair grounds to-day free of
charge Teachers accompanying children
will be admitted with their charges The
board also decided to admit inmates of
benevolent institutions accompanied by su-
perinterdents or persons in charge. Old
soldiers properly Identifying themselves
will also have free access to the grounds.
The Morgan & Wright bicycle team will
arrive to-day. This is one of the most
Noted teams in the country. 1t includes
Gimm, the champion twenty-four-hour man;
Charles Miller, the five-mile record man,
and De Cardy, the ten-mile record man.
The famous Arthur Gardiner will be here.
JOHN Lund and Herman Van Herick, both
of whom hold worlds records on tandems
Fred Schineer, Fred Rau and Joseph Skel-
ton complete the list of riders. All are in
charge of John West, one Of the best
trainer there will be a machinist to look
after the wheels and three rubbers to care
for the men.
The effort of the sextuplet team will be
to beat two minutes. 1t will be the first
attempt of this kind on a circular mile
race track. In Chicago the best mark at
taiIed on race course was ia. ihSre
have been lower records made on straight
away courses, but six men doing q mile
pretty clip for spectators to view. The
trial of the sextuDlet team will be made
Thursday afternoon. Tn the display OF ma
Chimes from that Ca ying six riders TO the
ordinary tandem, will be seen the famous
CUNT used to pace John S. Johnson and
the noted French riders on the Paris
tracks The hour of the daily parade will
be made known tomorrow.
There seems to be great deal of interest
on the part of the public in the X-ray
spectacle which is to be one of the main
attractions at the state tair during the me
will give d complete demonstration of the
x rays, from their discovery to the present
high state of development. He will show
many tubes of odd and fantastic designs,
and graded as to exhaustion, emitting
beautiful and brilliant electrical displays.
He will explain all of the apparatus and its
uses, including a powerful induction coil,
with twenty miles of wire, capable OF
throwing a twelve-inch rpark. Probably
the most interesting feature of the per-
Torrance will be the powerful Horoscope
which enables the eye to behold objects
through the most obaque substances; for
instance, a pocketbook containing coins is
placed under block of wood six inches
thick, and the coins show plainly. This in
strument is used in locating bullets and
other foreign substances in the flesh. also
broken bones the spinal column and in
watching the action of the heart.
The accidental manner in which the X
rays were discovered is interesting, and
through mere chance For many years
scientists have known that when certain
kind of electical discharge was made into
a tube from which the air had been par
tally removed that most peculiar and
startling results followed Professor
Crookes had gone 50 far in his investiga-
tons with highly exhausted tubes that sew
eral years ago he announced to the world
that he believed he had found evidence
fourth state of matter. Usually people
think of matter as existing only in three
fTorms-solid liquid and gas-but Professor
Crookes, after whom the X-ray tubes are
named, believed that matter exists in a
fourth state, namely. the radient' state.
1t was While experimenting with these
hfghly-exhausted Crookes tubes that Pro-
lessor Roentgen accidentally gave to the
world this startling scientific discovery
phecy regarding fourth state of matter
has almost become verified. At least Pro-
lessor Roentgen has given to the world a
view OF state of matter capable of oc-
cupying space simultaneously with other
matter Professor Roentgen. while expert
menting with one of these highly exhausted
Crookes tubes watching it fuoresce
wished to make the laboratory entirely
dark. He picked UP a heavy wooden cloth
and placed it over the tube completelv en-
veloping it. AS he was feeling in the dark
ness Tor apparatus he by chance picked up
piece CT cardboard about six inches
square, upon which some peculiar chemical
had been accidentally spilled To his great
astonishment he saw that the entire sur
lace or tne card was all Sglow with beau
tiful blush phosphorescent light AS the
room was entirely dark, he came to the
conclusion that some unknown force was
al work which was in some way connected
with the tube. He placed a large book of
TOUR hundred pages between the card and
the tube, and noticed that the Noard still
mad the same peculiar glow. He continued
TINS line OF investigation, placing many OBJ
Jects between the card and the tube, and
always with the same results. At last he
used, instead of the cardboard a sensitized
plate, and then, placing his arm and hand
between this and the tube the results
which followed showed him beyond a doubt
that he had discovered a new light that
was capable of penetrating opaque sub
stances.
For the benefit of teachers and pupils of
the public schools who will attend the fair
to-day Professor Miller has consented to
reproduce this scene in detail. as related to
him personally by Professor Roentgen, and
show all those interested how this discOv-
cry was given to the world purely through
