The problem of profitably produc-
ing beet sugar in the west has appar-
emily been solved The factory at
Norfolk, Neb., has manufactured and
sent to market within about four
weeks, fifty-two carloads of the best

The rice harvest on the farm near
Kissimme, Fla, that has heretofore
been worthless, yielded about sixty
| bushels per acre for the first crop and
the second crop will yield about twenty
bushels more. This will put Florida
rice in the marketat time when there
is very little competition, and will
bring better prices than later in the
season.
When Lord Beaconsfield invested

science has long been gazing toward

existence has long been indicated and
its position established.
1t is stated that Argentina wheat
can be grown-fifteen bushels to the
acre-at a profit of thirteen cents a
bushel if sold in Europe at seventy
cents bushel. The crop this year, it
is added, is So, O0O 900 bushels over and
above the needs for home consumption.
In the eight months ended August 81
there were nearly 30, 000 900 bushels of
the surplus exported. But one-twen-
tieth of the area of Argentina suitable
for wheat growing is now under culti-
vation.
"A very interesting topic, which is
winning it's way to attention, is the
periodic and secular variation of the
latitude of places on the earth's sur
face Prof. Chandler has been labor
iously nvessigating these movements
for some time. He has examined rec
ords extending over the last half cent
ury and including $4,000 observations
of latitude, and has come to the con-
clusion that the observed value of lati-
tude is the resultant arising from the
superposition of two periodic tluctua-
tions. These are-(al, one of 427 days
due to separation of the axis of rota-
tion from the chief axis of inertia, and
OBJ an annual one due to the periodic
shifting of the earth's center of gravity
in connection with seasonal redistribu-
tions of moisture. knowledge.
