SCIENCE AND INDUSTRY.


One of the industries of London is
the selling of sea water, which is de-
hvered at the purchasers house for two
pence gallon. 1t is brought to town
every night by the railroad companies.
"A new California industry has been
started at Santa Monica. 1t is that of
putting up mussels in glass jars by
process that makes them exceedingly
palatable.
The Irish Registrar General, in his
report on the potato crop in Ireland,
announces that. 78O, 901 acres of potatoes
were planted in 1890, as against 7s7, ,234
acres in the preceding year, and that
the yield had decreased !, 1,037, 1913 tons.
The largest olive-oil factory in the
world will soon be built at Los Guilicos,
in Sonoma county, Cal. The plant will
cost a quarter of a million. The COM
pany has sixty acres ofsix-year-old trees,
and is planting 700 acres.
One of the greatest problems of the
future is thought to be the trans
formation of carbon energy into light
upon the same principle that the glow
worm and FREELY give their light, and
when single pound of combustible
material will furnish as much light as
is now obtained from ton of coal.
To detect fecal matter in drinking
water, Greiss recommends feebly al
kaline solution of para-diazo-benzol-
sulphuric acid, which, with water con.
taminated as indicated, will produce
yellow diseoloration within five min
utes. Try it on the old we'll next sum.

According to an account from Milan,
the National Bank of Italy is actively
interested in the organization of an
Italian steamship company for East
Africa. The capital of the company is
to be 2O,OOO.OO francs (about 81, 600, OOO),
and its immediate object will be to con-
meet the Somali and Zanzibar coasts by
line of Italian steamers, so as to be in
dependent of the English enterprise.
The base of celluloid is common
paper; by action of sulphuric and nitric
acids it is changed to gun cotton, then
dried, ground, and mixed with from
twenty to forty per cent. of camphor,
after which it is ground fine, colorcd
with powder colors, cast in sheets,
pressed very hard, and at last baked be-
tween sets of super-heated rollers.
Rear Admiral Bellxnap, of the
United States Navy, combining his dis
covery of the greatest oceanic depths
vet found in the Japanese Kuro Siwo
with what other explorers have found
in different oceans, announces the con-
clusion that, "as rule, the deepest
water is found, not in the central parts
of the great oceans, but near, or APP
proximately near, the land, whether of
continental mass or island isolation"
The specific gravity of 3 new-laid
egg varies from 1.0S0 to 1.090; an egg,
therefore, is heavier than sea water, the
specific gravity of which is 1.03G. When
kept, eggs rapidly lose weight, and be-
come specifically lighter than water;
this is owing to the diminution of bulk
in the contents of the egg, the conse.
quence of which is that portion of the
inside of the egg comes to be filed with
air.
The production of paper in the en-
tire world is estimated to be 5000, 900, ,oOC
pounds per year. There are S84 paper
mills and 1.1O6 paper machines in this
country. Germany has 500 mills and
891 machines; France, 420 mills and SO;
machines; England, S61 mills and 541
machines; Scotland, SO mills and 90 ma
chimes; Ireland, 13 mills and 13 ma
chimes; Russia, 1S3 mills and 1877 ma
chimes, and Austria, 22O mills and 27t
machines.
One of the most hazardous manufac
turing processes is likely soon to become
thing of the past The great increase
of celluloid manufacture in recent year;
has made camphor so scarce and deal
that the chemists have been eXertinG
themselves to find substitute for tina
gnm. Some one has now succeeded il
doing so, and company has beer
formed to manufacture the new prod
net, which is described as possessing
all the good qualities of the old infam
mable compound of gun cotton ant
camphor. while being cheaper and, il
