SCIENCE AND INDUSTRY.

About $50, 900 barrels OF. cider and
perry are annually made in the western
counties of England, the sweet in Here
ford and the rough in Devon. In the
Dominion of Canada about 100000
gallons of cider are drank yearly.
Upon investigating the causes that
led to brittleness in the manufacture OF
horseshoe nails, it was found that the
pan in which they were annealed was
not we'll luted over, and that enough
air leaked through to affect the nails;
too great an amount of oxygen was the
trouble.
Trials of compound armor plate at
Shoeburyness, England, are held to
have demonstrated that, when these
plates have been submitted to the IRE
sidden supplemental process, they pos
sess powers Of resistance and endurance
much exceeding the compound plates
tried in this country in competition
with nickel steel
The quantity of cheese exported
from Canada in 1891 was 106, 202. 900
pounds, of the value of $9,50S, 800, as
compared with "a, OOo, 900 pounds, valued
at s., 900 in 1874, and SO, 755, 42S
pounds, value $7,251 ,9S9, in 1884. This
rapid development in the manufacture
| of cheese naturally limited the output
| of butter.
I'm many cases on the continent
there are no tolls whatever levied upon
the canals, and in others the charges
are merely nominal So much is this
| the case in France that the amount OF
traffic along the canals and rivers Is
rapidly increasing, until now the guam
tity of merchandise entering and leav-
ing Paris by waterway is more than
third of that conveyed by rail.
| Paper manufacture is one OF the
leading industries of Corea. Besides its
use for writing paper, it is employed In
a great diversity Of ways, such as string,
and in the making of lanterns, hats,
shoe soles, coats and boxes. 1t is made
from the bush of the mulberry order,
which is indigenous, growing in many
parts of the kingdom, but thriving best
in the moist, warm climate of the south.
in the new form of telescope for
stadia work spider lines are entirely
omitted, and instead prism is placed
so as to cover one-haf the objective of
the telescope, the consequence being
that the rays passing through the prism
make an angle with the rays passing
through the unobscured half of the OBJ
jective, and this angle Is constant what
ever the distance of the object observed.
Speaking of oleomargarine, Prof.
Charles F. Chandler, New York's most
eminent chemist, says that the opposi-
ton to its use is unreasonable and based
mainly on commercial and political
motives. In fact it is composed of pre-
cisely the same chemical constituents
as butter made of cows milk, and peo-
pie who will be offended to find it on
the table in place of butter, find no
fault with beef suet served up In mince
pies and plum buildings.
1T is proposed, says Nature, that
Englishmen shall celebrate the fourth
centenary of the discovery of the new
world, and do honor to the memory OF
Columbus by establishing in Jamaica a
marine biological station on the lines
of the marine laboratories at Naples
and Plymouth. The institution would
be called 1.-THE Columbus Marine Bio
logical Station" For the establishment
of the laboratory on a sound basis an
outlay of s75, 900 will be required.
Some trials with solicited petro-
leum were made few weeks ago at the
works of the Solicited Petroleum Cor
poration at Hackney Wick, London, and
they demonstrated that six-horse
power tubular boiler containing eighty
gallons of water could be heated by 9:
pounds of the Chenhall fuel Tor solidi
fed DILL, and in 36H minutes steam
raised to indicate 90 pounds to the inch
while it took 106 pounds of coal ant
wood to raise steam so pounds in ont
hours time.-Engineering and Mining

Chile, with an area of 29s, 970 square
miles and population of 5000, 900, pro
duces 81, 900, 600 bushels of wheat, "a,
600, 900 gallons of wines and othe
things on like scale yearly. The wood
of Voldivia are famous and the fruit o
Coquimbo is greatly esteemed TIL
foreign trade of Chile by the latest sta
tistics is $40, 000, 900 q year, equally di
vided into exports and imports. Chill
is an illustration of what a developed
South American country can do. Tn
United States imports from Chill
amounted to %, 1873, 24s, and her export
to Chile were ss,145,6s7. Should an in
ter-continental railway be built /
would develop large commercial inter

Italy $3.50, 0o0, 900. Sweden is now tn
greatest center for match production
owing to the plentiful supply of WOO
