I'm France hard water has been sue.

trolysis, tho method used being com.
2arativcly inexpensive.
According to the st. Louis Globe
Democrat, Carthage, Mo-. furnishes
Ircc-fOurths 81 the worlds supply Of
zinc. The amount got out averages $780,
300 worth every week.
DR.. Justin, Of Syracuse, has organ.
lied S5.0O0.0oo company to manufac-
turc his dynamite shells. which will
blow mp invading warships as certainly
rs that dried apples will blow MP boy
who cats too many OF them.
A rope company in st. Louis re.
,entiy made what is claimed to be the
largest shipm mt of cable ever carried
by one car. Two reels Of wire, weigh
ing 10000 pounds. were shipped ON .
special four-truck platform car.
1t has been concluded that with q
balloon $50 feet long. with maximum
diameter Of IS feet, speed Of - to 80
miles can be attained. At the same
time it is thought that the problem Of
tight Is more likely to be solved by
means of an aeroplane than with the
balloon.
John b. Mason. a mill ovcrseer at
Fall River. says the majority of women
snd girls in the factories there dip"
snuff. They moisten n wad of it and
tuck 1t down between the under lip and
the gum. where its presence Is always
revealed by little lump the size Of
bean. Here is another field for the re-
former.
An ingenious Frenchman has dis
severed 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. It il
estimated that Lyons alone will effect
IN annual economy of $4,000.
1t is mistake to suppose that the
weather is colder the further north one
goes. Tho northern pole Of greatest
,old is only about three hundred miles
northeast of Yakutsk, Siberia, where
the mean annual temperature II 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 US, issues
only about 1000 or 5000 n year, and its
system is very much more lax than
ours. Patents are issued without any
conditions rs to the novelty or merits,
md not two applications in a hun
fred arc rejected. In Prussia the
number granted annually is less than a
hundred; in Belgium l. 500 to 1000. The
American inventive genius has become.
il would seem, almost a monopoly.-N.

skeleton which was brought from the
Bcring sea. specimen of this particu-
,ar kind OF animal. known to scientists
Is Rhachiancctcs glaucus, has never be-
fore been brought to this country. It's
present ha bitat is found in the northern
parts Of the Pacific. and in the sen Of
Kamchatka; but it is believed to have
mad much wider range in past times,
Tor 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 60, OO0. OOO 900
lnd 100, 600. 001, 900 codfishcs arc taken
from the sea around the shores of New
'foundland every year. But even that
quantity seems small when we con-
slider that a single cod yields something
, like $500, 900 eggs each year, and that
over 100000 eggs have been found in
the roc of single cod. A herring Of
six or seven ounces in weight is pro-
gided with sc, 200, 900 ova After max
ing all reasonable allowances for the
destruction of eggs and of the young, it
aas been calculated that in three years
: single pair of behring's would produce
i54. OOO, 900. Button once said that ii a
pair of behring's were left to breed and
multiply undisturbed for a period Of
twenty years, they would yield 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-
zines, located upon the hurricane deck
and on the betwcen-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.
Accommodation are to be made for 200
Rrst-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, DR.. de Bausset says, will be
tornadoes The lookout, he adds, would
be sure to see these, and by the explo-
sion of dynamite will be able to dissi-
pate them.-N. Y. World.
