readers. Il first occurred OF G railway

inside surface OF the window glass daily
paper which mad been cut by q saW-toott
cutter, Leaving ragged edge On watch

the bits remsined cliDeiog TO the
glass. II was curious, and oegsn to In
yes.igste WITH larger pieces. All would

TOOK different kinds ofpiper tier, but the
results were The same SlCce the1 / have
repeated the experiment great number
Of times On different railways, sad always
found the glass apparently electrified. l.
cannot be capillary attraction, as the most
porous kind Of paper, II light, viii
stick Just the same. Ibave had pieces o:
newspaper two inches square hold firmly
Aud Strange thiug, toe, the phenomenon
appears sc certainly il rSi1y weather,
even when the window panes s:e stream

window for good rRsults. One evening
tested seven windows in one car, and
had them .sll spotted with bits OF

Now, why does the paper ctlck? Is il the

Will s:icz jest SIS efeclually. Is It due to
ths heat OF the fSger in applying the
paper? Nd, because 8 lead pencil or a

DO LOCOMOTIVES CAUSE RAINi
A correspondent Of the Northwestern
Railroad advances curious theory for
the Increasing prevalence CT foods and
rsin storms. he says that there are over
30. 0C0 locomotives IN use in N )rth Amer
ica, and estimst- that from them alone
over 55 600 200. 900 cubic yards OF vapor
are sent into the atmosphere every
week, to be returned in the form
OF rain, or over 1000, 900 600 cubic
ysrds q daY-"quite enough" he
says, "to produce good rainfall" every
twenty-foHr hours. Estimating the num-
Der Of other non-ccndensing engines in
uge as eight;imee the number OF ocono-
tives, The total viper t1us prof 3cted iato
the sir every week in t6is country
amounts to over 100000 00O,0 600 Gu oic
yards. SIS THE not" he asks, "sufli ;iens
for the foods OF terror? Is there any
reason TO W lder why our storms are so
dAmaging?"
CIvILIzING EoMEwHAT NOISY GREAT.
q '.-URE
Berl!n engineers have adopted two Diff
fefent systems for diminishing the noisy
trains on their visducts. One il, to bolt
to the Bridge structure long trcughs OF
shee. iron, about sixteen inches wide, so
arranged that rail will come IL the cen.
ter Of each. The trcughs are then filed
with gravel, In the middle of which
is buried the long itudinal timber carrying
the. rail, snd the space between the
troughs Is covered with iron plates, on
which Is spread s&hin layer of gravel
The second method, which Is found to
be more etli.ient than the other, consists
in placing 8 continuous series CT shallow
iron troughs, about five feet square, along
the line Of tracks. These are filed with
gravel, on which the ties and rails are
laid.
PRODUCTS OF COAL,
A tou Of coal yields aoUut 5000 cubic
feet Of gas and 1900 pounds cf coke. TIE
publication OF gas furnishes forty five
gallons Of SmmOpiS water, from VIII oh is
obtained euiphAte Of emmonis for agri
cultural purposes and SPOUT $50 pounds
Of tsr. Il is here that the operation be-
cones especially Interesting, for from this
last named producs are obtained seventy
pounds Of pitch, eighteen pounds Of
creosote, nine Of naphtns, thirteen Of
heavy ellis, SIX OF nsphths line, four Of
nspthol, two Of elizsrine, about one each
of phenoI, Gurine and sniline (the suo-
stance CT which We ere indebted for SO
wonderful ColCTs), ten ouUces Of tolui-
due, six OF anteracins and twelve OF

ELBCTICITY' RGR YELLOW FEVER.
A Kentucky physicisR-suggesLs the fol-
lowing cure for yellow fersr, claiming
that the poison in ths air is SO delicate
and subtle that II csn be dissipsted By
strong light: "It this is fact" ssys the
doctor IN e communication to Surgeon
General Hamilton, az am Of
the opinion that il row of large
army tents were.. spresd along the
center Of some stysst in Jacksonville for
tne Inhabitants to take refuge in, after
having been thoroughly dsinfecsed with
8 sufficient number OF electric lights ar
ranged near the ground On either eide Of
them, the wires, Of course, being well
grounded, that the lights could be
made so intense as to repress the poison
and stay the destroyer
MICROBES IN ICE WATER.
Microbes "a ice-water were found IN
large numbers by c. Fraenkel (Zeltsca.
fur HYGIENE while Investigating the

nished Ey German ice factories. The
NUMBER OF micro-orgsn rs found in the
cubic centiueter of lie water from ice Of
one factory WAS all the way from twenty
one 20 600. The ice from other works
had from PIC to $500 in each grsmme.
Another Investigator, Blscnof had
