A Breslau firm OF mica manufacture
ers is bringing out "A new insulating
material which il expects will super
sede micanite TO large extent for in
sulatlng purposes. especially FOR the
construction OF commutators and the
manufacture OF field magnet spools IL
Is cheaper than micanite. and being
made solely OF mica and asbestos, has
the additional advantage that IL can
stand much higher temperatures with
out softening.
Ii is said that farming is conducted
in Germany on more scientific prin.
ciples than anywhere else In the
world. The farmers there use less
machinery than those OF some other
countries 10. but they pay more atten-
ton 10 chemistry. particularly as it re-
lates TO the fertilization of the soil. In
spite of the advantages this gives
them, however, they can supply only
seven-eighths of the home demand for
breadstuffs. A part OF the onc-cighth
deficiency is made good by an annual
importation or about $4,000 600 bush
els Of wheat alone.
The production of oxygen ana by
drogen on an industrial scale 10y the
decomposition OF water with electro
lytic apparatus in Germany has led
20 the suggestion that hydrogen thus
produced may find wide field OF en-
ployment as a lighting agent. 1t is
now used FOR initiating military bal.
looms. For lighting purposes il is
compressed in steel cylinders. With
n proper burner IL is said To be a cheap
or illuminant than acetylene. the rcla.
tive cost for equal Illuminating power
being rs twenty-five for hydrogen TO
fifty-nine for acetylene.
That cotton can be successfully and
protitably raised In the Southwest has
just been determined by tests made in
Arizona. DR.. \. j. Chandler the own
er OF large area of land in the east
crn part OF the Salt River valley, has
just completed exhaustive trials with
Egyptian cotton, and has found such
satisfactory results that he has re-
ported TO the Department OF Agricul-
tire. His initial crop has just reached
maturity. In many respects the val
leys OF Southern Arizona and OF MeNl-
GO are similar TO the valley OF the
Nile. There is little difference in soil
and climate, and irrigation Is neces.
sary.
Extensive coal deposits have been
lound in Southern Norway. but IL Is
of poor quality. On the Island OF
Ando. one of the Ncsteraalen group.
In latitude siXty-nine degrees, IA bed
of coal was recently discovered In
which are evidences that the earth
must have suffered violent commissions
about the period when the vein was
formed. 1t extends under the sea a
long distance. with strata OF sand
stone, clay aud slate lying upon H.
Biologists say that the island must
therefore at one time have been larg-
er than now ana thickly clothed with
vegetation. For long period after
IL must have been submerged again
and then uphcaved anew.

the young plants have to bc protected

fatal to them. To secure this protec.
tion the planters shield them by ban

leaves OF which give them the needed
shade. And even when thcy are fully
grown they need protection, which is
given by trees known as "Hmmortels."
