Six or eight tons OF cast iron can
be made into steel In twenty minutes
by one operation.
The woman who can control her
own tongue Is greater then he who

7. Star.
1T has been estimated that after
lapse OF ten million years the sun can
not give out sufficient heat to support
life ON earth.
The fabric knownas Chinese grass
cloth is made from the fiber of nettles.
The cloth is peculiarly glossy and trans
parent and as betting for machinery
has double the strength of leather.
Two substitutes for the high priced
gum arabic-one from tlax-seed and the
other from starch-are expected to
serve all purposes for which the genu-
Inc gum Is used.
Without taking into account the
small variations due to refraction, etc,
the days and nights are always Of equal
length at all points on the equator,
without regard to the position of the
ecliptic.
Steel is iron with from one-half TO
two per cent of carbon. 1t was former
iy prepared by heating wrought iron
with carbon till it took up the proper
quantity. tits now made on a large scale
by the Bessemer process of burning
out the carbon and silicon of cast-iron
by forcing blast of air through the
molten metal.
Additional experiments have been
made. and with good success, with the
new French method OF coating pipes
with cork. A layer of cork is first en-
ployed, asbestos coming next. and
finally another layer of cork. The tenn
perature inside the pipes was some
1000 Cent, and after $50 hours the
temperature of the outer surface Of the
coating was found TO have only risen to
81 ..

the power generated simply by the
heat of the sun, has succeeded in rails

IN the future the energy from this
