elcctrlC arc llgnt W per cent Is waste,
and in the incandescent lamp % per
cent. Tho insect world is much more
economical; the most careful measures
made with tho delicate bolometer fail
to show any sensible heat in the light
Of the FREELY, and 1t is argued that there
Is no reason why nature should not be
successfully initiated in this respect.
Only careful readers OF technical liter
ature can realize the advances made in
tho manufacture OF pressed steel in this
country, and tho statement Is mudo
that some OF the most complicated
forms in this line arc now produced
here moro successfully than in Europe.
One OF tho latest achievements is a
steel bottle intended for cream separa.
tor-a bottle some nine.sixlccnll OF an
inch thick, uniform throughout, OF
eighty pounds weight, and having only
one opening, that at the top. Sweden
is said to BIO tho only other place where
these bottles aro manufactured.
Tho Wilderness OF Koolan, in the
Sandwich islands, contains q forest Of
native wild apple trees, countless in
number, stretching from the sea far up
the mountain sides. The trees vary
from forty to fifty feet in height, and in
the harvest season, from July to Sop
tember, arc loaded down with fruit,
some white. but mostly red. Tho or
chard stretches over 4 country from
five to ten miles wide by twenty miles
long, and many OF the larger trees bear
ut least fifty barrels apiece.
The brcad-fruit tree nourishesin many
OF the islands OF the South Pacific ocean,
and also in some OF the islands OF the
East Indies. 1t is comparatively large
tree, averaging, perhaps, one foot in
diameter. The fruit is rs large rs Il
child's head. 1t Is covered with thin
skin and has relatively small core 1t
is snowy white and about the consist
ency oil newly baked bread. In order to
prepare it Tor food it is cut into large
slices and roasted.
The degree OF dclicacy which has been
attained in the application OF the radio
mcromcter for the measurement OF
radiant heat-viz., from the candle, q
fire, the sun, the moon, tho stars, or
anything else which radiates heat in
space-is pronounced marvellous by
scientists, n single illustration OF this
power being afforded by the fact that q
really appreciate effect is produced on
that instrument by u candle placed two
miles away.
A very superior quality Of brick is
now manufactured from the waste sand
employed mt the factories in grinding
and polishing glass, which necessarily
accumulatcs in such large quantities.
The bricks thus produced have specific
gravity OF only LIS, and are perfectly
white.
The new Maxim flying machine will
be propelled by a light screw making
$500 revolutions per minute. Its sus-
pending power will be 4 kite no feet
long by forty feet wide. The motive
power will be petroleum condensing
engine.
The camera and an ordinary oil lamp
are now being used to produce photo
graphs OF the indicator cards in steam
engines, by which the working of the
engines can be seen and studied at all
times.
A recent eruption on the suns face
was photographed and lasted for fully
fifteen minutes. It's angular height
showed it to be disturbance causing
the vapors to ascend fully $4,000 miles
The wear upon the Cape Cod coast is
shown to be at the rate OF 1855, 1856 cubic
yards per year, or an annual wear OF
the coast equal to q distance OF about
eight feet
Theoretical researches in dynamics
do not indicate that any vapor what
ever is capable OF giving more than
five per cent OF increase in economy
over steam.
The Calumet and Hccla works have
smelling works in Buffalo, the capacity
OF which will be $50 tons per month.
