Lavender has suddenly appeared in
South Australia, the plant springln2
up luxuriantly over a la:ge area OF
black swamp in the south of the
colony. At first the settlers thought
the plant was weet. but on finding
out its true nature they resolved to
cultivate lavender on considerable
scale, with the view of establishing .
regular perfumery trade.
The salmon syndicate of the north
west are all busted in encouraging the
increase of the Pacific coast salmon.
Fifty thousand million salmon are
turned loose into the rivers of Oregon
by the syndicate alone every year, and
as the industrious female salmon lays
900 eggs to every pound of her weight,
the prospect of the fish seems encour-
aging.
1T is a well-known fact that heav-

Photographic plate. A practical illus
tration of the value of photography in
this connection is found in the expert
ence of March. when no fewer than
eighteen small planets were detected
photographically. Twelve of these were
discovered by NJ Charlois, at Nice.
The scientific world of Germany
has suffered another heavy loss in the
sudden death of Prof. Hermann Schaaff-
hansen. the famous anthropologist of
the University of Bonn. He was a pupil
of Johannes Mueller in Berlin in the
sos After extended travels he became
a professor at Bonn in 1914. He was
one of the first advocates of the theory
now known as the Darwinian. He was
born in 1916.
DR.. Schott. of Germany. has been

of ocean currents, the height of waves

exploiek the idea of waves mountain

they do net rise higher than thirty

This is how to extinguish candle
without blowing or snuffing il out:
Take piece of thick copper wire coiled
in spiral at the end. Fasten the other
end to a wooden handle. Hold the wire
30 that the coil will be around the
flame of the candle and very quickly it
will be extinguished. The copper, by
It's great conductivity, takes the heat
away from the flame and cools it SO
rapidly that the temperature falls be-
low the point of ignition and the light
goes out.
Prof. c. v. Riley, who has been for
years recognized as the leading Ameri-
can entomologist, and is, as report has
it, to be made assistant secretary OF
agriculture, has probably done more
than any living man to rid agriculture
Of its pests. His work and experiments
have long been among the most import
ant features of the agricultural depart
ment, and it is through his writings
and lectures mainly that farmers are
able now to exterminate easily what
have formerly been considered VERT
able insect plaques.

eye, and the older anatomists have OBJ
served that such difference does exisI
in nature; but quite recently Herr
Greet has actually measured the dis
parity, and finds that while the average
radius Of the cornea, or apple of the
eye, is 7.s3 millimeters for men. it i.
only 7.s2 for women. Other measure
ments by Donders give 1883 ant
I.799 millimeters respectively. ly.-Cas

In 1892 the cotton crop of the soutl
was valued at about 1915, 200, 900. Tn,
corn crop was valued at s24s, 900, 900
s25, 900. 900. These three products theI
were of equal value with the cottor
crop. Adding to them the value of to

culture in the American colonies, bu
failed. He sent silk worms to Virgini;
and offered bounty for silk clotl
manufactured there. but the planter
found the cultivation of tobacco NOR
profitable. Some silk fabric was sen
to Charles III. in 1868. Early in the las
century it was introduced in Louisiani
and the industry was also undertaken
in Georgia. In 1874 Oglethorpe tool
