There is talk Of putting feet of cleo

1t has been found that milk can be
thoroughly sterilized by heating it to a
temperature of 140 degrees Fahrenheit.
A recent improvement in making
water conduits consists in imbedding
wire netting in the cement used. The
piping thus made is greatly strength
ened.
]. J. Mcdonnell, Day Chief Operator
in the Western Union Telegraph office at
Tacoma, Washington, has developed
sextuple system of telegraphy and ap-

Frederick Schwatka, who once ex-

degrees below zero in the Arctic regions,
is said to be the only civilized being
who ever endured such cold.
The Dead Sea loses every day by evap-

| This enormous mass is easily drawn up
by the rays of the sun, the valley wherein

the globe.
The skeleton of whale, over 100
feet long, has been discovered buried in
the sands on the shore Of Baranhotf
Island, off Alaska, far above the high
tide mark. 1t is supposed to have been

Pipes of cement, in which wire net
ting is imbedded, are now manufactured
in Berlin, Germany. The wire netting
is said to greatly increase the strength of
the pipes against bursting, so that they
are well adapted for water conduits.
Recent experiments show that the per-
manency of the power in magnets is
greatly increased by heating them in
steam and remagnetizing them. When
this has been done several times the
magnet will suffer very little from heat.
When Portland cement is mixed with
water and used in atmosphere below the
freezing point ID will set, but rapidly
disintegrates. 1t has recently been
found that the mixing of a small amount
of caustic soda will overcome this diff
Guilty.
To say that Venus and Jupiter recently
came in conjunction is figure of speech,

A novelty in the line of building ma
terial comes from Germany, where a
firm has perfected q means by which
sawdust is mixed with an acid and the
whole is then pressed into the required
shapes. The process makes the material
non -combustible. 1t is lighter than iron
or steel and stronger than wood, being
also very cheap.
Electric heating is now attracting great
attention, due in part to the success
which has lately been made in street-car
work, but more particularly to the in-
crease in the possibilities of obtaining
current at reasonable figure. The
strides made in the transmission of power
from cheap source has opened up very
wide field for this branch of the electric
art.
Miss Eleanor Omeroed is the most dis.
tinguished entomologist of England.
Her first object in taking up the science,
it is stated, was to save the farmers
grain from destruction, and, in orler to
render herself familiar with the habits of
insect life, she often spends hours
stretched upon the ground studying
them. She has been appointed Consult
ing Entomologist TO the Royal British
