SCIENCE AND INDUSTRY.

The modes of fishing for oysters arr

eating. At Minotca the fisherman sim
ply dives to depth Of seventy feet
with weight In one hand to carry him
down. With the other hand he picks
up as many oysters is he can carry. and
brings them DIP to the boat.
between two small lakes near
Boras, Sweden. strip of land has in.
corrupted traffic, bat engineers havs
overcome the difficult by constructing
ship railway across it and building
small steamboat that can run itself
across from one lake to the other. The
vessel has accommodations for sixty
persons
"A much sought desideratum. namely,
. really practicable method of water
proofng leather and raw hides. il
claimed TO have been practiced by an
Austro- II hungarian chemist, with much
success, his method being to impreg-
nate the material with gelatine solu'
ton, combined with some mineral sslt
to soagulate the gelatine in the pores.
An sounds, whether high or low,
loud or soft, travel at precisely the same
rate, / e., about loo feet b second.
Were this not so the different notes OF
music would reach the ear at different
times, and the result would be eonfu-
sion instead of melody. If the sun
gave forth sounds loud enough to Teach
the earth, such sounds, instead of reach
ing us in the space of about eight min
utes as light doeA would only arrive
after period of nearly fourteen years
AN interesting incident showing at
how great distance conversation
can be carried on is related by Lieut.
Foster, of the third Parry Arctic expedi-
ton, in which he says that he conversed
with man across the harbor of Port
Bowers, . mile and quarter away,
and it has also been distinctly asserted
on good authority that at Gibralter the
human voice has been distinctly heard
at distance OF ten miles
1T is stated that the shipments of
pork product, including pork, bacon,
hams and lard, from the United States
for the year 1890 were ], e21, 900 pounds.
The total consumption of pork product,
exclusive Of lard In the United States
during 1890 is estimated at 3,653, 600, 600
pounds, which would make an annual
consumption per capita of over fifty
eight pounds. The domestic consump-
ton of lard is about $40. OO0, 900 pounds,
or about 8 9 per capita
The Photographic analysis of rapid
movement has made great progress In
a recent series of instantaneous photo
graphs Anschutz, of Lissa, has secured
twenty-four successive impressions of
dog in the act of making single jump
over a low bush, and each impression 10
not q mere silhouette, As was the case
with Muy bridges first attempt of this
kind, but little picture showing half
tone and detail. Some of the attitudes,
never caught by the eye. seem quite
amusing. This is true at the COM
mencement of the jump. when the dogs
hind toes only touch the ground, and at
the end of the jump. when his legs are
gathered together in q heap.
Storms are now considered great
eddies in the atmosphere. There are
two kinds of eddies In one the air
blows out spirally from the center in all
directions, the weather is generally
fair, the air dense and the pressure re-
corded by the barometer high. In the
other the air blows spirally inward from
all directions, the weather is more or
less cloudy and rainy aud the barometer
is low In the northern hemisphere the
winds circulate around the former in
the direction of the watch hands, and
around the latter in the opposite direc-
ton. The whirls. with inblowing winds
and low barometer, form our storms,
which, in this latitude. generally move
from the west or southwest. and appear
to be carried along by the general
movements Of the atmosphere, like ed
dies ON the bosom of the river.
