SCIENCE AND INDUSTRY.

-Dairying in Germany has been none
the less rapid during the past decade
than in Denmark or Sweden. In 1882
exclusive of Bavaria-there were only
about 100 large diaries in the Father
land, but ten years later their number
was increased to 2,672, of which 1,O2O
are cooperative.
-Raisin growers of California are
forming trust Packers and brokers
will be admitted, but the entrance fee
will be higher for them than for grow
ers Raisins will be consigned only to
packers and brokers who have given
bonds of $40, 900 and $50, 900 respectively
not to sell under prices fixed by the
trust
There are about 200, 00O. 900 of acres
of uncultivated land in India, not in
Guiding forests. On much of this land
trees could be planted, which, with a
little care and expense at first, would,
in few years, afford an abundance of
fuel, and later on a wealth of excellent
timber.
On Norwalk Island the wool crop
of last year amounted to 1920 pounds
and sold for 10 cents on the spot Farm
prospects were married by bad weather.
Potatoes and onions hardly realized
any paying price. The best market
for Norfolk Island products is Noumes,
in New Caledonia.
Z Great Britain imported, during 1891,
1876, 900 cattle less than in 1890. the de-
crease being attribute BILE to lesser i'm
portations from Denmark, Canada and
the United States. The receipts from
Denmark were so, 900, from Canada 49,
600 and from the United States $4,000
less than in the preceding year.
Belts that slip can be cured by COW
ering the pulleys with canvas. Wrap
the canvas twice around the pulley,
using the following mixture to keep it
in place: White glue, six pounds; white
lead, in oil, two pounds; nitric acid, one
fourth ounce. Dissolve the glue in two
quarts of soft water, mix in the white
lead, add the acid and employ the mix
ture hot.
The expedition sent out by the vi
emma academy of science to explore the
Mediterranean found its greatest depth
to be something over two and one
quarter miles, between Molla and Cert
go. On the African coast, where the
water is clearer. white metal plates
could be seen at a depth of IA feet.
Sensitive plates were acted upon hs the
light at depth of over 1000 feet.
The waters of the oceans and seas
OF our globe hold not less than 6O,OOO,-
600, 900, 600, 900 tons of salt in suspen-
sion. If these figures are correct and
the ocean should be entirely dried up,
there would be deposit of salt $50 feet
deep over every foot of the great basin.
If taken out and spread upon what is
now dry land it would give us salt
covering nearly 1900 feet thick.
The mode of depositing it's eggs
practiced by the locust tree borer
Cyllene robinia) has been described by
Mr.. Jack in Garden and Forest He
noticed the beetles laying their eggs
August 23. The eggs are large, oblong,
white and soft, and are placed just
under the edges of the toughest bark
or more particularly in places where
the bark has been broken and where
small limbs have been cut or broken
off. A favorite place also is around the
openings of their own burrows.
The bottom of the North Atlantic
ocean. says Prof. Huxley, is one of the
widest and most even plains in the
world. If the sea were drained off, a
wagon might be driven all the way
from Valentia, on the west coast of Ire
land, to Trinity bay, in Newfoundland.
From Valentia the road would lie down
hill for about 200 miles, to the point at
which the bottom is now covered by
LOO fathoms of sea water Then
would come the central plain, more
than 1000 miles wide, the inequalities
of the surface of which would be hardly
perceptible, though the depth of water
upon it now varies from 10, 900 to Is, 900
feet
