PROGRESS OF SCIENCE,


Paper barrels are coming
Electric mining is growing.
Electric welding is increasing.
Glass-coated bricks are announced.
Driving belts Of paper are in successful
use.
Sheet-iron kites, to enable vessel
when in distress during a storm to COM
municate with the shore, have been sug.
gested.
Recent Improvements in wire-drawing
have made it possible to draw platinum
and silver into wire that is finer than hu-
man hair
A recent improvement in the cork bag
ging for steam pipes consists in the sub.
stitution of asbestos en- the side coming
next TO the pipe.
Recent experiments in France on tho
velocity Of propagation OF electric waves,
give mean velocity which is almost ex.
actly that of light
A marine railway has been built az
Elzabethport, n Y, which is capable OF
hauling 2,500-ton vessel out of the wa
ter In nine minutes.
1t has been found that vaccination is
beneficial to horses having the glanders,
and this treatment Is now being used in
France and Germany.
Steel smokestacks are being placed
upon the locomotives OF tie elevated r,il-
roads in New York city. thus reducing
the weight from 500 to about 100 pounds.
Files are now slarpened by electricity.
They are immersed in liquid and tho
current turned on for twenty minutes, al
the end of which time they come out as
good as new.
Bergen, Norway, boasts OF paper
church large enough toseat 900 persons
The building is rendered waterproof by
solution of quicklime, curdled milk. and
whites of eggs
A velocity as high as 1857 feet pen
second has been attained by projectile
from rapid-fire gun. This is at the rate
Of 1858 miles an hour II is the highest
velocity yet recorded.
The loDg-talked-of utilization Of the
force of the ocean waves has been sue
cessfnlly put in practice on the coast Of
France. where this power is used to lift
heavy blocks Of granite.
The soldering Of two pieces Of alumni.
ium has heretofore been considered i'm
practicable, but recent experiments show
that it can be easily done by the use Of
chloride of silver as a flux.
Electricity has been used in Sweden as
a substitute for dynamite in blasting.
The strong current which is carried into
the rock generates such intense heat aa
to cause the rock to crack.
Rice in the hull, when heated ia tho
pepper like popcorn, burst open just like
the latter, and not only has the flavor of
real popcorn, but is crisper and much
more delicious to the taste.
An alloy which adheres firmly TO glass
and can therefore DO used for joining up
glass tubing, is said te be made by add
ing 8 per cent Of copper 10 95 per cent Of
tin. The tin is first melted and the cop.
per added subsequently.
A japanese chemist has succeeded in
cultivating a fungus abouuding upon
rice, from which rice ferment is pro-

II well be dug to the depth of forty
six miles, the density Of the air at the
bottom would be as greatas that Of quick
silver. By the same law cubic inch Of
air taken 1900 miles above the eartlls
surface would expand sufficiently 70 fiji
a sphere 1000, 900, 600 miles in diameter.
Cyclones originate in the tropics and
are chiefly found in five localities: The
West Indies, Bengal Bay. and the Chi.
nese coast. north Of the Equator; and in
the South Indian Ocean of Madagascar
and the South Pacific, near Samoa. In
the Antilles there are not half dozen on
the average every season.
