srd naturalists is taking in hand th9
protection of South African mammals
the giraffe, zebra, Gland, gnu koodoo
and other antelopes, against their
threatened extinction. suggested
method of accomplishing this is to
secure an inclosed park of about lOO,0
acres.
A method has at last been found
by n. H. Keyser of soldering aluminium
by heating the metal and Scraplng the
surface so as to remove the oXydizing
film until the metal is timed The
alloy used consists of so parts of tin,
% of silver % of aluminium, and melts
at 80 degrees. Almost any tin solder
will do. however.
According to some estimates 20 per
cent, and according to others as large

arising from this cause is absolutely
pr-oentable by at least two simple
means.
The total production. of whisky in
the state of Kentucky for the year
ending June 80, 1894, was 20, 1873, sos gal
Ions, and about 3,0O)OO) gallons of
this was spirits. OF this production
there remained in bond on June 80
1894, 17.OS5 92O gallons, being 1881, 42S
gallons less than the stocks of June 80
1898, and 7S5. 1874 gallons less than the
stock on June 30, 1892. -Bradstreet's.
AS Mars approaches the earth its sa-
tellites appear again on time and have
already been observed by several as
trOnOmers. The error of the ephcmeris
is very small, but it is worth noting
that our American Nautical almanac
in its diagram of the satellite-orbits
represents the motion in the wrong di-
rection. an error likely to mislead OBJ
servers in searching for the little
moons, which can be seen with a nine
or ten-inch telescope under favorable
atmospheric conditions.
To reach the north pole an archi-
| tect, NJ. Iauin. has proposed to the geo
graphical society of Paris the con
struction of wooden huts one or two
! days journey apart He considers
Greenland the most favorable locality
for an experiment of this kind. Each
of the huts would become in its turn a
base of supplies for the construction of
the next. AS the distance to be COW
cred is about 900 miles. a score of huts
would be necessary to establish a route
to the pole.
An account of the striking changes
which the great lava lake in kilauea
has undergone this year, appears in the
Hawaiian Gazette. The lava steadily
rose after the last great breakdown of
the floor of the crater in March. 1891,
when an area of $500 feet long. by
1000 wide, fell more than 500 feet in
one night. Toward the end of last
year the rising and overlooking of the
lake filled the pit thus produced.
Since that time the activity of the lake
has been intense, as many as twenty
three overfows of liquid lava having
taken place in a single day. and the
walls surrounding the lake have been
rapidly raised by continual overfows.
-Agneta Park, near Delft, in Hol-
land, is the result of an interesting ex-
pertinent in cooperation. A tract of
ten acres has upon it $50 houses, each
with its little garden, and with certain
common buildings and common
grounds. The houses are occupied by
the employees of great distilling com
pany, who form a corporation which
owns the park Each member owns
shares in the corporation and pays rent
for his house; the surplus after eX-
penses are paid comes back to him as
dividends. If he wishes to 90 away or
dies. his shares are bought up by the
corporation and sold to the man who
takes his place.
Col. Dulier, of the Belgian engi-
neerS, has discovered an easy and eco
nomical method of doing away with
London smoke The smoke enters 4
chimney shaped like the letter n: at
the bottom of the left-hand leg it is
met by a small jet of steam, which
saturates the smoke and accelerates
the draught; at the top of the leg a
spray of water drives down the SCOT
and noXious products, allowing only
almost pure vapor to escape up the
last leg. Half the acids and 81 per
cent. of the SCOT are thus removed;
they are sent down into the sewers,
where they act as disinfectants. The
system can be applied to factory for
about $3.50, and to a single dwelling
house for ST. or SD
Keen Scent of Animals.
l have often asked friends of mine
who have hunted in various countries
as to distance at which deer and other
wild animals can scent a human being;
and most of them seem to be agreed
that they will wind you more than a
mile off. | have certainly seen chamois
over half mile distant make off in
alarm when they could not possibly
have seen anything to disturb them.
1t is curious, too, how much more the
hunters odor seems to terrify them
than the mere sight of him. In the
latter case, unless you are quite close,
theys w histle and move off quietly,
turning around every few hundred
yards to look; while if they get your
scent they will throw up their heads
with an expression of utter disgust
that is highly diverting, and without
hesitating a moment galiop away at
top speed. -Lippincott's Magazine,
