Since Monaco engineers discovery that an
electric current viii free the soil from insects,
the idea has been held that electricity should
aid In abaking the insect plaques of southern
Europe. TO destroy beetle that greatly dam
ageB tender plants near Odessa, Lokuzejewski
has mounted 2 dynamo on q cart and arranged
the circuit 90 that the current reaches the earth
through the metal wheels on the one side and
on the other through copper-tipped brushes
placed in the rear few inches above the soil
All insects near the brushes are instantly killed
as II BY lightning. The fly infesting the olive
tree has received the attention Of DR.. Rapace,
and he has devised an arrangement generating
sparks between a metal panel and the leaves Of
the tree.
In treating red noses Paris physician uses an
instrument resembling very large tooth brush,
but having forty platinum wires instead Of bris-
ties. This instrument is as heavy as an ordinary
household hammer. It is connected with an
electrical machine. and is then used in hammer
ing the troublesome nose rather sharply for
several minutes. or until bleeding IL produced.
It is claimed that two hammerings week for
some months will tone down the reddest nose to
delicate pink.
The old idea that changes are taking place on
the moon has been carefully investigated by NJ.

latest, he concludes that the reality Of the sup

The 'Sherardizing'' process of Sherard Coles.
tie British metallurgist, IL q novel method Of
making alloys without fuslng the metals. In
recent demonstration by the inventor. a copper
plate was surrounded By zinc dust and heated to
500' =. for an hour or 80. when film Of zinc was
deposited on the plate, although the tempera-
turo had not been within 2O0o Of the melting
point Of the more fusible metal. The surfaceof
the plate was much hardened by the deposit.
Articles Of iron and steel-hrst made perfectly
c;ean-can be galvanized in the same way. and
the temper Of steel IL not impaired. The opera
ton can be carried out on large scale by pack
ing the objects to be treated in an iron drum
full Of zinc dust and then heating the drum.

The secret wireless telephone of A. 7. N. John
son, retired Australian Official. depends upon
steel reeds tuned in unison or octave to the voice
Of the person speaking. and. as voices vary
greatly, special reed is necessary for each per-
son. On speaking into an ordinary microphone,
q large RuhmkorR coil in circuit transmits the
vibrations, without connecting wire. to the re-
ceiving apparatus. Messages have been sent to
distances Of half q mile. Secret kilograms can
be sent through similar tuned steel reeds. and
these are received by secret bell arranged to
respond only to the vibrations from the proper
transmitter.
Electricity is likened to water. Sir Oliver
Lodge mentions that 1t Is no more form of en-
ergy than water. but. like water, 1t may be q
vehicle Of energy, when at a high level or in mo-
tion. Electricity cannot be manufactured, like
heat It can only be moved from place to place,
like water. and its energy must be in the form
Of motion or Of strain. Electricity under strain
constitutes current and magnetism; electrici
ty in vibration constitutes light.

Falls Of Rrolites to the earth's surface. like
the appearance Of shooting stars that are burned
up in the air. are found by Mr.. W. II. s. Monck
logue Of @rolites it appears that much larger
proportion of the known falls have taken place
in Nay and June than at other times, the num-
Der per dag for these two months being 134
while for the rest Of the year it is only 0S1 and
there are instances in which Rrolites fell within
one or two days of each other, on almost the
same date on two consecutive years, and on
nearly the same date after two or three years.
Such cases ESQ numerous as to seem more than
chance condolences. An analysis of the cata-
logue dates and numbers indicates a marked
tendency for series of falls to group about GER
tain dates, and for these falls periods of seven to
twenty years are deduced. That is, we may in
fer that the @rolites are drawn from collections
Of stones in space whose orbits are near certain
parts Of the earths orbit or approach the earth
at intervals of some years.

A simple agent in home surgery whose value
seems to have been overlooked is the skin or
membrane Of eggs. Calling attention to this at
arecent meeting of physicians in Paris DIR. Amat
cited two cases-a severe burn on young girls
foot and large ulcer on the leg of a man Of
forty-in which six or eight pieces of the egg
membrane had been placed over a wound, which
was then covered with tin-foil fastened with dry
antiseptic bandage. After four days the mem
irritation being fastened and a good growth Of
new skin ensured.
Since the blowing of train from their bridge
some years ago. the Furness Railway of Great
Britain has installed high pressure guage, with
suitable recording apparatus, on the western
side Of the bridge. This not only keeps con
slant record of wind pressure but automatically
sounds an alarm 80 long as any gale is strong
enough to endanger passing trains.
THE TOWN of Havre-de.Grace is one of the
most progressive places in Maryland. It's high
school building has been completed, at cost
Of over $40, 900. and it is a structure that does
the town great credit. 1t contains fourteen
class and recitation rooms and has every mod
ern convenience and comfort. Havre-de-Grace
is an incorporated town.
AN Epidemic Of CHAMBERS has been discovered
among the horses in York county. Pa, and in
one neighborhood there are said to be over
thirty cases. The State veterinarian has taken
the matter in hand. Horses that are killed,
or taken in charge. are paid for at the rate Of
$40 per head.
FORTUNE IS thrust on some people. A Cana

was sunk by food. Theincrease in the value
Of the raft amounts to large sum.
