The curious phenomena of alloys
are only beginning to be known.
Seeking an alloy that would give an
iron interior with bronze veneer-a
thing that proves to he not at all i'm.
possible or mpracticable-C Vickers,
British metallurgist, made a series
OF experiments in the course of which
iron was melted in a crucible and
alleged with aluminium. 1t was de-
sired to learn the effect of adding a
small percentage of zinc. A two
ounce bit was cautiously tossed upon
the molten mass, when, after few
second, series of muffied explosions
ensued, and the mixture in the cruel
BILE was shot upward toward the root
of the shop, giving beautiful pyro-
technic display, the iron producing
star, and the zinc yielding dazzling
blue light, while fakes of molten
metal glowed between. This con-
tinued until the crucible was emp
tied.
In manufacture, caoutchouc is
mixed with sulphur, or vulcanized,
and with various mineral substances
and organic fbers. Worn-out rubber
has been worked over for some uses
for many years, but no way of COM
pletely purifying has been known,
and it has lacked strength and elasti-
city. The improved process lately
announced by W. E. Reid depends
upon A. Tixier's discovery that
vulcanized rubber is completely solu-
BILE in terpinol. The old rubber is
digested with terpinol at moderate
heat, benzene is added, the clear solu-
tion is poured away from the insolu-
BILE impurities, the liquid is distilled,
and the residue is treated with
alcohol and acetone. The recovered
caoutchouc is much like the natural,
is very viscous and capable of vul-
canization, and has increased resist
ance to chemical action.
The telephone, apparently so ex-
tremely sensitive, is found by Henry
Abraham to transmit to the ear less
than thousandth of the energy re-
ceived from the line.
In the production and control of a
pure food supply by thoroughly
scientific methods. the Germans are
disposed to keep their lead. The new
government institute for. milling re-
search, supplementing the two in
stitutes for research in the sugar and
fermentation industries, is equipped
with an experimental granary, a
wheat and rye mill and a bakery, to-
gether with administrative offices and
laboratories, the machinery and
apparatus being of the most advanced
kind, all driven by electricity. The
mill has two distinct plants, each
milling two tons of grain in ten
hours. The purpose of the institute
is to carry out practical research and
scientific investigation on grain dur
ing storing, milling, working up and
baking; to experiment with the bak.
ing of home and imported grain; tc
conduct research;work for the govern.
ment, and to carry out official and
private analyses of grain, flour,
fodder stuffs, etc. Every effort will
be made to investigate thoroughly the
numerous problems of milling and
baking.
In the work of reclaiming the %, OoC
acres in the great peat boys of KONG
smoor and Marcardsmoor in the Leel
district, East triesland, the land will
be drained by network of % miles
of canals, and station for general
ing electricity will be established al
the junction of the main canal will
the high road from Leer to Wittmund
Current from this station will be dis
tributed over an area thirty miles il
diameter. The peat will serve as fuel
the plows and other machinery useC
in fitting the land for cultivation
being driven by power from the DO,
product, which will also give ligh
and power to many surroundin,
towns.
A factory at Grossalmerode, Ger
many, manufactures a patented tele
graph pole of glass intertwined wit
strong wire. This pole is specIall
adapted for use in hot climates, an,
successfully resists the attacks o
weather and insects that soon destro
the ordinary wooden poles.
The secret ballot provided by tn
Automobile Club of America in it
palatial New York clubhouse consist
of a small two-drop annunciator, sup
piled with electric current by a set @
four dry cells, and having wires ex
tending around large table to
button block at each of the chairs a
the table. When the board of govern
ors is to vote on an application fo
mem bership, the face of the annur
ciator is covered with a curtain
Each member of the board the
presses the white or black button c
his block, and if any black button
pressed the black disc is seen whe
the curtain is removed from th
annunciator. 1t is impossible to teI
