According to the st. Louis Globe
Democrat, Carthage, Mo-, furnishes
three-fourths of the worlds supply of
zinc. The amount got out averages $780,
900 worth every week.
DIR. Justin, of Syracuse, has organ
lied S., ZOO, 900 company to manufac-
ture his dynamite shells, which will
blow up invading warships as certainly
as that dried apples will blow up boy
who eats too many OF them.
"A rope company in st. Louis re-
Gently made what is claimed to be the
largest shipment of cable ever carried
by one car. Two reels of wire, weigh
ing 100000 pounds, were shipped on q
special four-truck platform car.
1T has been concluded that with q
balloon $50 feet long, with maximum
diameter of IS feet, a speed of IS to 80
miles can be attained. At the same
time it is thought that the problem Of
fight is more likely to be solved by
means of an aeroplane than with the
balloon.
John B. Mason, mill overseer at
Fall River, says the majority of women
and girls in the factories there dip"
snuff. They moisten wad of it and
tuck it down between the under lip and
the gum, where it's presence is always
revealed by little lump the size of a
bean. Here is another field for the re-
former.
An ingenious Frenchman has dis
covered process of recovering the tin
contained in the wash waters of silk
which have been weighted, and he has
accordingly received from the French
society for the encouragement of ma
tional industry the prize allotted for the
utilization of residual substances. 1t is
estimated that Lyons alone will effect
an annual economy of 5000
1t is mistake to- suppose that the
weather is colder the further north one
goes. The northern pole of greatest
cold is only about three hundred miles
northeast of Yakutsk, Siberia, where
the mean annual temperature is little
lower than in the highest ATTITUDES
reached by Mares and Greeley 1000
miles further north.
The average number of American
patents issued yearly is about 10000.
Compared with the number issued in
any country this is very large. En-
gland, which comes nearest to u.s. issues
only about 1000 or 5000 a year, and its
system is very much more lax than
ours. Patents are issued without any
conditions as to the novelty or merits,
and not two applications in hun
bred are rejected. In Prussia the
number granted annually is less than q
hundred; in Belgium 800 to 1900. The
American inventive genius has become,
it would seem, almost a monopoly.-N.

The new natural history at South
Kensington has lately had an addition
to its treasures in the form of whales
skeleton which was brought from the
Bering sea. A specimen of this particu-
lar kind of animal, known to scientists
as Rhachianectes glaucus, has never be-
fore been brought'to this country. It's
present habitat is found in the northern
parts of the Pacific, and in the sea of
Kamchatka; but it is believed to have
had much wider range in past times,
for fossil remains of the species, or of
one very nearly akin to it, have been
found both in Norway and Sweden.
1t is said that between &C, 600, O00. 600
and 100, 600, 0O0, 900 codfishes are taken
from the sea around the shores of New,
foundland every year. But even that
quantity seems small when we con-
slider that single cod yields something
like $4,000 eggs each year, sand that
over 5000, 900 eggs have been found in
the roe of a. single cod A herring Of
six or seven ounces in weight is pro-
vided with 30. OO0, 900 ova. After max
ing all reasonable allowances for the
destruction of eggs and of the young, it
has been calculated that in three years
single pair of behring's would produce
154, 0OO, 00O Button once said that if a
pair of behring's were left to breed and
multiply undisturbed for period of
twenty years, they would yield a fish
bulk equal to the size of our globe.-St.

DIR. A. de Bausset is the protector
of an air-ship, which, he says, he be-
lieves will successfully travel in the air
at the height of four and one-half miles,
or just above the region where rain be-
comes snow. The ship is to be 72s feet
in length to be made of steel with an
alloy of aluminium, and is pointed both
at the front and rear. 1t is to be pro-
PEELED by dynamous and explosive en-
gines, located upon the hurricane deck
and on the between-decks of the car
underneath the ship. The car is to be
fully equipped with all the appliances
of latter day six-day ocean steamships.
Accommodations are to be made for 200
first-class passengers, with their bag
gage, and from fly to fifty-five tons of
mail matter. The only danger to be
feared at the height in which the ship
will travel, DIR. de Bausset says, win be
tornadoes. The lookout, he adds, would
be sure to see these, and by the explo-
sion ~ dvua mite will 1,n ahle IN diSsi,
