Mr.. CoXwELL, the English balloon
ist, maintains that the conditions of
the Arctic regions are such as to rem
der the ordinary methods of balloon
ing impracticable in that quarter.
IT is announced in the Japanese pa
pers that iron has been discovered in
the sacred mountain of Koga-san. Its
existence has been suspected for many
years, but superstition forbade the ma
tives mining it. Operations for work.
ing the ore will now be Immediately
commenced.
AN unfortunate strike of the cabi-
net-makers in Dublin is in danger of
destroying that branch of business,
not only in the city, but in Ireland.
The workmen have been on strike
for over twenty weeks, in consequence
of the employers refusing to grant an
advance of sixty-two cents week
demanded by the men. There are 800
men employed in the city. nearly all
partaking in the strike.
| EXPLOSIVES substances have recently
been put to novel use in Austria.
Cartridges of dynamite are planted at
a depth of nearly ten feet at a proper
distance from the vines, about the
roots of which the earth was to be
loosened, and upon explosion sepa-
rated the earth for distance of nearly
six feet so that it could be permeated
by the air and moisture. Here is a
suggestion for enterprising farmers.
J.. THE Malays resort to very curious
method of killing the rhinoceros. The
animal, being fond of wallowing in
the mud, will find spot in a marsh
where the soil is about the consistency
of. dough. Here he will remain for a
long time, and when observed by the
Malays they will, approaching eau
tiously from behind, pile combustible
material over him and set it afire.
The intense heat bakes the mud so that
the rhinoceros cannot escape, and
then, the fire being continued, cooks
the animal. A curious coincidence is
here found, for the remains of mas
todon were recently discovered which
gave evidence of having been disposed
of in the same manner by savages who
existed centuries ago.
NJ. HOZEAU has recently suggested
81 ,,,nJn Of Ipct on rNaHo
etc, which, if experience demonstrates
its practicability, will be found both
simple and useful, and be no insignif-
cant boon to man and beast. He pro-
poses to merely mix with the water
that is now employed in the usual pro-
cess of sprinkling thoroughfares
small quantity-amount not stated
of chloride of calcium. This, he
thinks, will form patina or crust of
considerable resisting power, which
will last for several days, and which
will hinder both the drying of the soil
and its diSintegration by vehicles, etc.
At the same time, also, it will prevent
the growth Of weeds, and thus on
private roads and walks prove labor
saving.
LEAF PRINTING.-The old method
of taking impressions of leaves and
delicate plants and ferns by using a
sheet of oiled paper saturated with
lamp-smoke and pressing the object
first upon that and then upon white
paper, must give way to very excel
lent refinement of he process. A
sheet of paper is oiled on one side only
and then folded four squares. The
leaf is then pressed between the sec
ond folds where the oil reaches it only
by infiltration through the tissues of
the sheet. Removed thence 1T is
placed between two forms of clear
white paper and being pressed evenly
with the hand, two almost invisible
images are obtained, which being
oleaginous may be brought out by sift-
ing fine black-lead powder over them.
Ifpowdered crayons or colors are used,
natural effects of color may be pro-
duced. If a little resin is mixed with
the black-lead or crayons, it will serve
to fix the image ON the application of
sufficient heat to melt it.
