men ha" been at worK, some studying

ticular method claim that the photo
graphic effects are due to the produc
tion i-f x-rays, but whether the ray
are produced remains to be seen, and
there are some scientists who already
duubt the similarity between the ac
ti..ns in the methods mentioned and
the action In a Crookes tube.
The photographs produced by the
x-rays show the shadows of obJectA.also
any variation in structure. From the
fact that the shadows of different sub
stances, the metals for Instance, have
different intensities. It Is naturally sup
jKoed that some are more easily
travTsM by the rays than others. Ex

Thf fXiNxure of a plate to the effects
of a fnx'kes tube is a comiarativoly
iinplf j.i.K-ehs Since glass acts as an
liu- w reen. and 'because there is no
waj of tx-ndfng the Tays out of their
course i.) a lens or other tutsans, a
C4mrr is of no service. All that Is
dun in making an exiosure Is to place
the ebjtvts to be photographed between
the tut., and the plate, the latter "being
held in an ordinary plate holder.
Tht- -joe is the most lmiortant part
of the . ; lunatus and must be made with
ca.-e, w ing to the high vacuum neces
seems natural "to conclude tha't the
x-rny are not cathode rays.
A number of scientists are Inclined to
bellove that the x-wy Is some sort of
molecular action, porhnps of itho other,
and thnit the vibrations are longitudinal
as In the cathode my. The action or
the tays In opposite to that which would
be noticed In the case of electrified
particles. It Is yet to be determined
whqthor the wave length Is very short
or very long. A slmplo neat secma to
show that the nature of the x-rays Is
similar 'to that of the ultra-violet ior
tlon of the spectrum and this mny also
show that the wave length Is very short.
A property of alio x-ray Is thait of
causing clllorescence of certain sub
stances, barium plntlno-cyanlde being,
perhaps, the beat for this purpose. Hv
substituting a screen coated with 'this
compound for the photographic plato.
tho portions not protected by hidden
objects will give light and In this way
the exaot location of the objects can be
seen directly by 'the eye. It 'Is barely
possible that the action upon pho
tographic plate Is not due to ony chem
leal action which these particular rays
have upon 'the Mm. but is n secondary
one due to the efflorescence of the salts
In the film and It Is this light which
produces the chemical change. As a
support of this theory, we have the re
port of an experiment made by Edison
upon plates having different degrees
of quickness. He found that the slov
landscape plates were quickest for this
new process. Is it not probable, then,
that the salts 4n the slow plates give
a stronger efflorescence than those in
the quick or instantaneous plates and
in this way produce an effect opposite
to that which ls observed with ordinary
light?
The conductors of plnitlnum wire are
sealed into tho glass wall of the tule
at some dlwtanee aiart and usually at
right angles to each other. In order
to prevent excessive heating of these
conductors (due to the action within the
tube) and consequent danger of the
destruction of the vacuum, they are pro
vided at the Inner ends with knobs or
djscs of some metal, prefero-bly of alum
inum. These two terminals are known
as the "anode" or "flowing-ln" pole, the
"cathode" or "ilowlng-out" pole.
When the discharge from an Induc
tion coil is jwsslng through the tube,
the whole Interior is dark with the ex
ception of the region of the cathode
where the cathode rays have their ori
gin and which iass from the terminal
to the opiwslte wall of the tube in
straight lines if no external Influence
Is brought to bear uion them. Where
the cathode rays strike uion the glass
the phenomenon of efflorescence Is pro
duced and it Is from this efflorescent
spot that the x-rays are sld to have
their origin.
The possible uses have been much
discussed In the various newspaers.
so it U unnecessary to take up space
with the long list. As to the value of
the process both for scientific and for
practical uses there can be no doubt,
and not a few scientific facts are looked

Word wan received Friday by
friends In the city of the death of Will
C. Hall, a former student of the univer
sity, and in U98-Ki an assistant In the
zoological department.
lir. Hall was t- close student, on ac
curate observer and a genial, compan
ionable man. who seemed destined to
do a good work in life. He was com
pelled (to gle up his school life on ac
count of the appearance of Brlght's
disease. By living in the open air and
by careful attention to his diet his phy
sicians hoped to ward off fatal results,
but a few months ago he was ordered
to Arizona and told that he could not
endure a northern wWter. The tele
gram Indicates that Mr. Hall died on the
20th at Temole. Ariz. The case is all
the sadder from tho foot that Mr. Hall'B
father Is very ill with rheumatism at
Hot Serines. Ark., while ano'ther mem
ber of the family is recovering from a
berlous illness at the family home at
Croston, la.

sat for last Friday a 1 o'clock.
Some lively caucus An? wns done dur
ing that week, but no one seemed to
know how It would come out. Three
officers were praclfcully conceded by
the lenders as bohyg fettled. They were
MoKrv for one edltoMn-ehief and Pier-
on nnd Russell for business managers.
ThO fight was evidently to be made
on the other edlur-ln-ohlef. Vet up
to the last day evrybod seemed to
think It would be apoclety man.
In fact a ticket jo9 made out with
Boomer of the Del hats in this place and
a very fair division f the board among
the fraternities, soefctit-s and outsiders,
it seemed probabld that this ticket
would carry with tttle opposition till
Friday morning. t that time the
members of the diss outside or both
fraternities and sorietles came to an
understanding an.o&g themselves and
insisted that Barroishould take Boom
er's place upon the ticket.
With this Idea in view a new UCKei
was printed with JcKoy and Barron
as editors In chief and Plerson and
Uussell as buplnes(aauagih-s. and a
board consisting of six fraternity peo
ple, four from the societies and four
outsiders.
These two were practically the only
tickets that c ame up when the meeting
was called at 1 o'clock.
Business managers were voted on
first. J. E. Plorson and l'hil. Huiwell
getting all but a few straggling votes.
For editors In chief Will U McKay
was upivorted by both tickets and re
ceived practically the unanimous vole,
while I. J. Barron was elected over
Boomer by a two-thirds majority.
As members of the board the ten
named below were fleeted. rceivln.:
pluralities In the order named: John
Tuttle, George Burgert, T. D. Lunn,
Ellen Gere, Lisle Wilkinson, Charles
Morrison. E. A. Wlggenhorn, C H.
True, W. Axllng, L.. J. Belknap.
A staff of artists was elected con
sisting of Jessie Uuulnr Vergil Barber.
Pearl Wycoff, Miss Lytle. C. C. Culver,
May Wilson.
Thus it was started. During Ahe past
week the business managers have re
ceived several bids for printing and In
time will be able to report to the ed
itors and the class the prospects for
the annual.
Regardless of .the tussle for the offi
cers the class is a unit in Its desire for
the success of the Annual and every
member wU work bard for its good.

be for want of ability and push.

Now. when the son had got him Into
"the olty and began to look around him
he nearly dropped dead. Ills knowledge
of the deceitful nnd designing female
sex lmd been limited to old maid school
teachers and cross-eyed farm girls nnd
ho marvelled exceeding much at the
frat girls with their Henry Tilt, plumes
nnd dotted veils nnd Trilby walks and
ho said unto himself. "Forsooth this
la tight In my line." and he telegraphed
home for Home shekels.
And It came to imss that the son got
the regulation four second Introduction
to one of the girls nnd he straightway
began to do the right thing. Moreover,
he wns a young and callow youth ?.!io
did not understand the noble nno1 popu
lar nrt of limb JerWng, so when the
girl began to throw around broad hints
about oysters and theatre tickets, he bit
even as the sucker blteth. and stood
oft his board bill. But It eventually came
to pass that he broke the family bank
nnd on a centaln night he spent his
Inst round samoleon for flowers for his
charmer and It chanced that about this
time the girl got onto the state of af
fairs and decided that she must look
for another fellow, so she put an extra
curl on her forelock and powdered her
nose and throat and sailed out for a
new victim and she didn't have to sail
long, either. And It came to pass that
when the farmer's son come to loo' for
her on the dancing floor that night he
found her In the corner with another
fellow. And behold, she had given the
other fellow one of his roses to wear.
And the farmer boy wist not why At was
so. And he waxed exceeding wroth and
grew warm beneath the collar and he
nranced un txi where the pair were
chinning each other and said: "O, faith
less maiden, Is this your gratitude?
Mcthinks this is a rather raw deal. You
give this duffer the roses tlm I paid
for and he gets your smiles and pleasant
looks. Now what forsooth do 1 get?"
And the fair maid looked up and said,
"You get nit!"
And It dawned upon the farmer boy
that he was getting -It in the neck and
he sneaked out, and in the morning he
had to pawn the family watch to get
him meal ticket.

I The Pershing Rifles company thus far
this venr has hardly realised the ex
pectations of Inut spring. The election
, of Johp Dixon to the captaincy wns
surely a wise and valuable step. Pre
vious to Mr. Dixon's acceptance the
members of the company had lost nearly
all Interest; a few vMithuslasts alone at
tended the regular drills.
Dixon saw what wn needed and went
to work nt onct. The splendid drill on
charter day Is one of the results of his
wrrk. Vrom this drill Interegt has
awakened In the compnny to an intense
degree, not only In the members, but
nlso In tho friends outside.
Thursday night very important action
wns tnken toward partially reorganiz
ing the company.
It wns decided that the ofllcers and
non-commlssloned ofllcers would remain
the same, but the roll of privates would
bo materially changed. A committee,
ccrslstlnc of Parmelee, Gage, Soxton,
Reed, Sedgwick, Pulls and Schwarz was
selected to hunt out nnd bring In the
best men of the battalion, also to cull
out the poorer members of the company
In this way only the very best men
w 111 become members and such men as
can always be depended upon.
A line of 25 cents Is to be Imposed up
on nil absentees. The non-payment of
which within one month is to be con
sidered ample cause for expulsion.
Alone the social line which is the pol
icy of the company the pursue, a com
mittee was selected to look Into the mat
ter of getUng up a Rifle's hop.
Already such actions as above are
having the desired effect.
Men are trying hard for the positions,
and the Pershlngs are nearer the centre
of Interest In the university now than
any other student organization.
Xow this Is not only aitrue story, but
a common one, and If 1 should tell who
I have In mind there are half a dozen
other fellows who have been through

Once upon a time there was an old
man and he had one son and It came
to pass that when the old man had
husked his pumpkins and harrowed his

berries, he decided to send his promising

hours of eight and a quarter after a
man with a cadet cap and questionable
actions, bounded with three leaps In

he arrived at the center of the room,
brandishing a pistol in one hand and the
cavalry saber, which had been strapped
across his back, in the other, and while
the members of the Co. Op. hastened
off to find McDowell, and while Uie
editor, in his ottlcial seat was reaching
calmly for his six-shooter, the gentle
men burst forth with, "We will be

you see the whites of their eyes," and

Conwral Hinds hearing the disturb

regular steps to the rescue. Arriving
at the Co.-Op. the little corporal com
manded by the "right flank march!"

Already a few snap shots had been

Makes us believe we cannot pass,
But when by chance we hap. to meet
In some swell place, or on the street.
Sticks out to us a hearty hand.

Who Is that Prof, that in his class
Has no regard for b-ys, ala.

Not of the kind you read in books,
But of that sweet, most heavenly kind
Enjoyed by few and hard to find.
