sunflower Seed.
Professor Wiley, chemist of the agri-
cultural department, has been making
experiments IN raising sunf1owers with
a view to the general Introduction CT
the industry in this country. In Rus.
STA this plant is cultivated as a staple
crop. There are thousands or tons of
the seed raised in the Ohio Valley and
elsewhere every year. but it is be-
lieved that the acreage can be increas.
ed many fold to advantage. In Rus.
STA the sunflower seeds are an article
of diet, being eaten either raw or
roasted. The oil is also used literally
in cooking, being practically equal to
olive oil. 1t is also useful for dressing
wool and for soap and candle making,
ETC. The seed makes an excellent
food for poultry and stock, the oil
imparting a peculiar sickness to
them. Any soil that will grow corn
is suitable for sunfiowers. The aver
age crop is from 500 to 1000 pounds to
the acre, wo' tn from 81 to S2.75 hun
dred weight. When mills are built
to extract the oil the value of the crop

Liquefied Air.
M. d'Arsonval made some astonish-
ing demonstrations with liquefied air
the other day in the Paris Museum OF
Natural History. BY enormous pres
sures he reached a temperature of
minus $50 centigrade. The liquefied
air was contained in a double-sided
silver-covered bottle, and did not evap-
crate. Experiments with india-rub-
Der bottles showed that, under the in.
fiuence of the intense cold, they be.
came as hard and brittle as glass. The
rubber could be pulverized, but be-.
came elastic again when the air was
evaporated. Similar results were
shown in the case of butchers meat.
M. d'Arsonval exhibited beef-steak
dipped in liquefied air and then let it
fall on the floor, where it sounded like
a stone and broke to pieces. 1t was
eventually reduced to pink powder,
easy to masticate and assimilats, and
likely to be of important service in
hospitals. Ice dipped in liquefied air
cut glass like diamond, mercury be-
came hard as anthony. Metals, said
M. d'Arsonval, especially steel, had
their qualities increased tenfold by the
application of liquefied air. Conduct
ing wires could be reduced to hairs
breadth in thickness and remain as
strong as enormous cables. 1t cannot
however, do anything to preserve
meat, he declared, as it is in no way
an antiseptic and will not kill microbes
Moreover, it is now five times dearer
than ice. 1t cannot be used for motor
carriages or submarine boats, because,
when heated it is such a powerful
explosive that no metal yet know
could resist its shocks. NJ. d'Arsonval
warned the French public against
schemes for preserving meat or pro.
polling motors by liquefied air-Lon-

When We are Hungry.
We feel hungry when the bloodves-
sells of the stomach are comparatively
empty. When food is taken and di-
gestion begins there is a rush of blood
to the stomach and the hunger is APP
peased. Many anemic patients have
no appetite even when the stomach is
empty; but the bloodvessels of the
stomach are not empty in such cases,
but rather congested. In healthy peo-
pie lack of blood in the stomach acts
upon a special nerve and all the
characteristic symptoms of hunger
follow. Now, this hunger nerve and
the nerves OF the mouth and tongue
are branches of the same nerve trunk.
Hence stimulus applied to the tongue
by spice for example, creates or
increases appetite. On the other
hand, when the nerves of the tongue
are affected by a diseased condition
of the mucous membrane of the mouth,
the patient has no appetite, though his
stomach may be empty and he may be
in actual need of food. --Staatz-Zeitung.
kammatograph.
Mr.. Kamm has invented a remark
able device which dispenses with the
long celluloid film used in the exhi-
bition of moving pictures, circular
glass plate taking the place of the long
film. On this plate the pictures are
made in spiral curve. A remarkable
feature of the Kammatograph is that
it serves the purpose of camera and
protector combined, thus dispensing
ammunition for the Lee-Metford and
other weapons with which the troops
in India are armed, which are
frequently sold by the soldiers, or
stolen, finds it's way into the frontier
district in the way of trade.-London
