SCIENTIFIC AND INDUSTRIAL.

Wood-fber capable of being spun is
now prepared in Germany The prepar-
alton Of the fiber Of pine leaves as a
material for carpets is another promising
new industry.
A tricycle. fire apparatus is novelty
in London, England. IL is propelled by
two riders, and carries pumping engine
and coil OF hose, and the total weight
is three hundred pounds
What is probably the first recorded
photograph Of a rainbow has been exhib-
tied 90 the Photographic Association Of
London. The arch has the appearance

Stree the first appearance of the great
red spot on the planet Jupiter some nine
years ago, Mr.. w. +. Denning, the we'll
known English astronomer, has made
about 300 observations of the Dhenoms.
non. He believes the red spot TO be a
feature OF Jupiter's atmosphere, and not
OF the surface of the planet.
1t is announced thut paper bottles are
20 be manufactured on very extensive
scale; their weight is less than those Of
glass or stone ware, and they are less
liable to breakage; paper being also an
excellent non conductor, fluids stored in
air tight paper bottles will Withstand a
more intense degree OF heat or cold than
when put in ordinary bottles.
A new use for dynamite was found in
the demolition Of factory at Harrisvillc,
n. H., recently which was TO be rebuilt.
Tho conclusion completely separated the
brick and did not seem TO iniure them
in the least. The charges were put in
holes dug in the foundation under the
brick walls, and the number Of cartridges
was graded according TO the number of
brick in the walls to be demolished.
Many artesian wells spout water under
a heavy pressure, Just as many gas wells
find the gas under a pressure of several
hundred pounds to the square inch.
This aterpower is used in many places
in France by means of turbine wheels,
and it is probable that even the gas pres
sure might in some cases also pc utilized.
In very deep artesian wells the heat Of
the water is also utilized.
Several of the French railway com
panies and other public bodies have re-
solved on having their printing done on
green instead of white paper. The
reason for the alteration is that they be-
licve the combination of white paper
with black characters endangers the eye
sight of their work people. Black on
green has always been recognized rs a
good combination, and many railways
tickets are so printed.
/ The introduction of the incandescent
electric lamp has offered the means of
providing the diver with a better illumi-
nation for his work under water without
adding any great additional compiled
ton to his dress. BY means Of small
lantern screwed to the upper sight hole
Of the helmet, fifty candle incandescent
I lamp can be carried in way which leaves
the hands of the diver perfectly free and
at the same time insurcs that the RAYS of
light shall always follow the direction of
his glances and fall upon his work. A
powerful reflector concentrates the
beam.
In some recent scientific experiments
on the effects OF cold, two frogs were
frozen solid in a temperature Of about
twenty degrees, and kept in that condi-
t on for half an hour On thawing
slowly they recovered perfectly, but it
was found that large periods Of exposure
invariably killed the animals. The ex-
pertinent was tried of freezing hermeti-
cally scaled meat, 50 as to kill its bacte-
rial organisms, and thus render it in
capable Of putrefying 1t was found,
/ however, that 81 low a temperature as
( eighty degrees below zero would not
destroy the vitality of micro organisms
IL was thus made clear that the attempts
| to preserve meat for long time by a
momentary freezing of it must be aban-
dOned.
