Butter made from cocoanuts is said TO
be heathful.

Butter made from cocoanuts is said TO

Linneus, the Swedish scientist, wrote
during his lifetime 1S4 volumes.
The practice of "cold saving" Of steel
and iron is being generally adopted.
Recent experiments by German physi-
clans indicate that cancer is contagious.
The new Argentine Pacific Railroad
has one stretch of road 2ll miles long
without curve or bridge, and no cut or
fill deeper than three feet.
Experiments in Chicago with cmmen-
site and gelbite show them to be one and
one-half times mole powerful than dyna-
mite and as safe to handle as pig iron.
For a good solution for removing the
blue from steel so as to leave as clean as
before coloring, try acetic acid, or soiu-
tion of chloride of tin (s.annons chloride).
Zinc expands up to the melting point.
A bar of hammered zinc six inches long
will expand one one.hundredths of an
inch in raising the temperature 100 de-
grees Fab.
A number of thoroughbred Merino
sheep have been introduced in the Cape
Colony, from the United Stltcs, in order
TO improve the quality of rhe South
African wool.
The Grand Canyon of tue Colorado il
simply the channel worn by the action OF
running water to depth of 5000 or
5000 feet. The sides of the canyon are
perpendicular cliffs fifteen miles apart.
The serious effects upon the eyes OF
miners from the use of the modern safety
lamp has been subject of investigation
in England, the result being that in
creased lighting power in such lamps
will cause such troubles to disappear.
By means of powerful jet Of com
pressed air a German engineer drives dry
cement down into the sand or mu at the
bottom of stream so that the water i'm
mediately fixes the cement and it be-
comes like solid rock, suitable for fou1lt-
tions.
A three foot vein of leal ore has been
discovered on the farm OF ]. HIlbin5,
near Breda, Carol County, Iowa, a.
depth of 300 feet. Expert miners at
Carol report that the ore is Of the finest
quality and can be mined to good al
vantage.
It has been concluded that whatever
preservative is to be applied, the timber
for piles, subjected to the action of sea-
worms, should first be charged, SO as to
kill any germs near the surface, open the
pores of the wool for the antiseptic and
destroy the nutritive matter upon which
the worms live.
Shells for firing high explosives have
been patented abroad, in which recep-
tacle is made containing compressed air.
By suitable appliances this air is released
suddenly, thus furnishing the propellins
power. Great range, no foulinS OF the
gun, scarcely any noise, and no smoke
are thus obtained, combined with great
rapidity of fire.
What seems to be an infaliable remedy
for the poison of snake bites is s)lution
of nitrate of strycbnine in 30 parts OF
water, to which a little glycerinc Is
added. This is used hypodcrmically in
doses of twenty minims, at intervals OF
ten to twenty minutes, depending upon
the condition of the patient. In 100
cases thus treated only one failure has
occurred.
In India the hsxseed grown up to the
altitude of 5000 feet is oil yielding.
Much has been done by the Indian GOV
ernment to foster fax culture among the
peasantIy, but with little success. Jute
holds the place of flax in popular favor.
The great enemy OF the flax plant in India
is the rust. The fax fiber, seed, aud oil
are so little in favor that the bulk OF
them is exported.
The enormous mass of extra weight
due to the carrying of the boiler, fuel
and water in the old locomotive will BE-
entirely unnecessary in the railways o.
the future, which will be propellci by
electricity. Unquestionably the future
electro. .locomotion will show motor on
every axle, or, at any rate, upon two
axles Of each car, and every car running
as unit, in which case they caa run
coupled together in a train or noS'a' may
be convenient.
