j The va erspout at sea is initiated
| by M, Loquers by placing layer OF
colored syrup at the bottom OF tall
cylindrical glass containing water
and then gently rotating the water
by means of spoon. In few Sec
onds the syrup Uses up into cone,
with apex prolonged upward until it
joins pointing cone formed
by the water. The two cones revolve
spirally in the same direction. The
substitution of small pieces of sugar
for the syrup gives further imitation
of details, undissolved particles being
sucked up and thrown outward, while
the lower cone is smaller than the
upper and moves much faster, small
or cones also being formed below IN
addition to the principal one. These
are phenomena of the atmosphere
when masses of it are set in rotation
by upper currents coming together.
Rubber waste is made again useful
according to newly patented Ger
man process, by dissolving the ma
terial and separating it from the
solution. Suitable solvents prove to
be aniline. toluidine and xylidine, at
14Oo to 1902 c.: and dilute acid
added to the solution causes the or
ganic bases to remain dissolved as
salts while the rubber separates as
tough mass. This is washed and
dried. The caoutchouc is recovered
for new uses without Decentralization
and the solvents may be removed by
alcohol.

Great improvement in the sighting
of the fixed guns of fortresses has
been effected by Sir George Clarke,
who has found that with the height
of the gun above sea-level given, the
angle of depression of the line OF
sight determines the range, making il
possible to arrange sight so that
when the movement of the gun lays
it on the water-line of floating tar
get, the gun shall have the proper
elevation for that rahge. These
auto-sights have shown great etfec-
tiveness in Royal Artillery tests.
The suns life is calculated by DR..
TIL. See at 100000 years, 49,
100000 having been already spent.

The pressing of cloth by means Of
boards heated by electricity, the |
''electro-calidor" process of M
Chedville, has been reported onby !
committee of a French industrial |
society as an important development.
The press boards are composed of |
asbestos paste covered by netting
of German silver, which in turn is
covered by paper pulp, the whole
having thickness of one-twelth to
one-sixth Of an inch. Electric con
nection is made through copper. Gov
cred projection corn 9rs. In filling
press, a piece of cloth is folded on
plate of iron, and three press boards
are placed between the folds at equal
distances, then another irln plate is
added, with another piece Of cloth,
and SO on. An ordinary press holds
eight pieces of cloth, the folds be-
ing meter wide. At the factory of
Messrs. Bin hollow presses are used
and ten Of them are placed on an iron
track in a system communicate 6
with hydraulic press. The electric
conductors run along the ceiling.
parallel with the track. A small wire
from the positive side and one from
the MIGHT'VE side are connected to the
copper corners of each press board by
clips, and the current is adjusted to
generate the necessary, abont 48 am

The usual requirement for each press
With coal at SIS 90 ton the maximum
cost of heating press is under Is
cents while by the old method of
placing in special oven it was 81
cents. There are more important adj
vantages than economy however such
as nice regulations of the heating.
