-Germany's average annual prodrc-
ton of wine during the past thirteen
years has been 80. 900, 900 gallons The
area of land under vine cultivation has
varied but little in that time, being
about 800, 900 acres. A third of the
total product is made in Alsace and
Lorraine.
The milk production of the chief
European countries must be estimated
by the millions and millions of gallons
a head. Germany heads the list with
3. l27 800 millions of gallons: next comes
France with 2,225,140 millions of gal
Ions: England is third with 1868, 500
millions of gallons.
Northern Delaware will have some
of the best wheat lands in the country.
One farmer in New Castle county re-
reports an average of 80 bushels per
acre upon 100 acres; another reports
an average of 3315 bushels per acre,
and another an average of So bushels
per acre. a small field. recently in
asparagus, yielded an average of so
bushels per acre.
The largest band-sawing machine
in the world has recently been COM
pleted in England and sent to Tasma-
MIA. The machine can saw through a
maximum depth of seventy-tive inches,
and the carriage will accommodate
logs fifty feet long and weighing about
fifty tons. 1t is asserted that this saw
cuts even faster than circular saw,
while wasting 10 per cent less wood.
1t seems hard to realize that the
lightest whisper must continue its
rounds of existence throughout all
eternity, yet on the belief that such is
the fact is based all modern physics
and very many of the useful adjuncts
of modern civilization. 1t is now real
lied that force, like matter, is indie
structible and that where matter is
we must look for force or energy in
close relation Ia 1t.
Interesting experiments with rat
tlesnake venom are in progress at the
pathological laboratory of Johns Hop
kins university. The captured rattler
is excited to strike at glass saucer,
into which the poison from its fangs
falls. This is then injected in minute

mails are dead they are dissected to
show the action of the venom.
The age of the late dragon tree of
Orotava was variously estimated at
from 5000 to 10000 years. On the low
est estimate it surpassed not only
Domesday oaks and Soma Expresses,
ba HaAcNr with its 300
years, and Alphonse Karr's baobabs,
of Senegal Balfour gives the ages, as
ascertained by De Condolle, of ths cy-
press as $50 years, the oak 1,50i, the
yew 2,s2O ard the baobab as probably
the same as the yew.
"A prominent English physician of
large experience with drunkards, Gays
that he can recall hundreds of recover
les among men, but only five aE,ong
women. AS an instance of the cunning
with W hich female inebriates gystify
their appetite for liquor the following
story is related. Some women in o re-
treat asked fer curling tongs, very
natural request. Next, they wanted
methylated spirits with which to heat
the irons. and finally they wheedled
hot water. sugar and lemon juice out
of one of the maids. Out of these
liquids they contrived a concocticn to
atisfy their craving for alcohol.
Various attempts have been made
to account for the diversity in shape
seen in eggs. A recent study conviuces
DIR. Nicolsky that the differences may
ali be traced to gravity. and he finds
his idea confirmed by all the eggs in
the geological collection of the ST. Pc
terSburg university. He supposes that
pressure by the sides of the ovary tends
to elongate the egg before the she'll has
hardened. In birds which keep YER
teal position while at rest, as do the
falcon and the owl. the soft egg is
made short by the action of the weight
of the body against the ovarian pres
sure; while in birds that. like the grebe,
are nearly always swimming, the egg
is heightened. because the birds
weight acts with the compression by
the ovary. The egg is made more
pointed at one end than at the other in
birds that. like the guillemot, are fire.
