"A French chemist believes himself
able to tell whether soil is deficient in
phosphorus, potash or nitroges. by the
shade of green of the vegetation. The
leaves become yellowish when nitrogen
is lacking.
There are four products of Cali
kOrnia," says a Pacific Coast journal,
which will shortly command the market

abroad. These are raisins, figs, prunes
and olive OIL"
DR.. Dornill, of Paris, says infectious
diseases are often transmitted by ice,
especially typhoid fever. He advises
the use ofartificial ice, made from boiled
or spring water, and condemns ice OBJ
tanned from ponds or rivers liable to
contamination.
nent in Cincinnati the large number of
$1,000 gold dollars are annually beaten
out into gold leaf-a statement not
more remarkable than the fact, as is
also asserted, that as many as 1,4OO
thicknesses of the gold leaf are required
to equal a sheet of thin paper and $780,
900 to form an inch.
The weight that can be lifted by
screw, or the tension that can be given
bolt or stud by using wrench to the
nut, can be determined by finding the
distance moved by the power or the
hand in making one complete revolution
of the wrench. Divide this by the pitch
or the screw, and multiply the quotient
by the power applied. There will be
from 20 to 75 per cent. deducted for fric-
tion.-The Jeweler.
"A congress was recently held in
Paris to protest against the abuse Of to-
baccco, says the Pharmaceutical Era.
Explaining why the German, who
smokes more than the Frenchman, poi
sons himself less, NJ. Ortolan said that
the percentage of nicotine in tobacco is
less when the stalks grow close together
sand when the leaves are numerous and
placed low on the stalk; hence in Ger
many, where tobacco growing is unre-
stricted, the amount of nicotine is less
than in the French tobacco, where the
industry is regulated by government
and the number of leaves to the stalk is
limited. French tobacco contains as
much as six per cent. of nicotine.
AN archaeological discovery was re-
Gently made in German Altenburg on
The Danube, in a curious manner. After
a weeks study, from an elevated point
of view, of an extensive corn-field,
whose colors showed great variations,
Prof. Hauser declared that an ancient
amphitheatre must be buried under
meath. The corn was quite ripe over
the centre of the ruins, where the soil
was thickest, and ellipticaI lines of
green growing paler the higher they
rose, showed the seats. Subsequent ex-
cavations confirmed this theory, and
brought to light the structure, with
paved road leading to the camp of Car
numtum.
Experts estimate the total value of
ladies' cloaks produced in the United
States at s4, OOO, 600 to S., ,OOO, 600 year.
About three-fourths Of the manufacture
ing of these cloaks is done in the city of
New York. Chicago comes next, Cleve-
land next. Boston, Philadelphia and
Cincinnati do still smaller business. In
the last seventeen years cloaks have
driven shaw1s steadily out of the mar
ket, until they have almost disappeared.
There is about $25, 900, 600 capital in
vested in the ladies' cloak business of
the United States. About $1,000, 900
year is paid in wages to the workmen.
To make 100000 600 worth Of cloaks
uses up about S25, 900. 600 worth Of do
mestic goods and trimmings every year.
