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 arnor 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 f06, 6,202, 900
pounds, of the value of s9,50s, 800, as
compared with "a, 900, 900 pounds, valued
at SO. .25S, 600 in 1874, and 69,755, ABB
pounds, value s7251, $3.50, in 1884 This
rapid Development in the manufacture
of cheese naturally limited the output
of butter.
in many eases 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

ing Paris by waterway is more than n
third of that conveyed by rail.

in the new form of telescope for
stadia work spider lines are entirely
omitted, and instead prism is placed
so as to cover one-half 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 T. Chandler, New Yorll's most
eminent chemist, says that the opposi-
tion to its use is unreasonable and based
mainy 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 buttei, find no
fault with beef suet served up in mince
pies and plum puddings.
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 The Columbus Marine Bio
logical Station" For the establishment
of the laboratory on sound basis an
outlay of S75, 900 will be required.
Some trials with solidified petro-
leum were made few weeks ago at the
works of the Solidified Petroleum Cor

Chile, with an area of 293. .97O square
miles and a population of 10000 ,O00 pro-
| duces 21, 600, 900 bushels of wheat, "a
| 900, 900 gallons of wines and other
things on like scale yearly. The woods
of Voldivia are famous and the fruit of
Coquimbo is greatly esteemed. The
foreign trade of Chile by the latest sta
tistics is S12O, 900, 900 year, equally d.
vided into exports and imports. Chile
is an illustration of what a developed
South American country can do. The
United States imports from Chile
amounted to So, 1873, PAS, and her exports
to Chile were So, 145, 627. Should an in
ter-continental railway be built it

The estimated production of
matches per year throughout the globe
is given at $50 milliards. Russia pro-

Italy $3.50, 100000. Sweden is now the
greatest center for match production,
owing to the plentiful supply of wood
in that country The output of some
of their factories is immense, averaging
from 100, 100000 to 200, 900, 900 boxes
per year, and they are exported to all
parts of the world. A sllillful worker
there can dip no less than 5000, 900
matches in one day Taking the whole
population of the globe there is an
average daily consumption equal to one
per head. The total value of matches
made annually throughout the globe
represents value of 9S7 ,0OO,O 900 ster-
