The latest ca~rrior-pigeon expert
ments in Europe show that tho normal
velocity of the bird ia about 1910 yards

direction of the flight almost 1000 yards

Very few people know that Georgia
produces olive oil. A planter in St
Simon's Island has a grove of 100 trees.
nearly in full bearing, from which he
has made about two hundred gallons OF
oil, besides the fruit picking.
The heat produced from the light of
a FREELY is only one per cent. OF an
equal amount of candle light. The
bugs light is produced by a chemical
action as it was increased by putting
the fly in oxygen and diminished in an
atmosphere of nitrogen.
There is now more beet than cane
sugar consumed. In 1881 the total of
the worlds production of cane sugar
was 2,OOG, 900 tons, and of beet sugar
I,774, 900 tons. In 1890 the total OF cane
was 9, 246, 900 tons, and of beets 3, $50. 900
tons.
Texas is wonderfully prosperous.
From all sections come reports of in

for the school fund and the lands held
by the State for the same are estimated
at 500, 900, 600.

Those who believe that horses will
presently disappear, not only from
street-car lines but also from the street
itself and from the country road, will be
encouraged by the announcement that
carriages to be run by gasoline are soon
to appear in London, and that "a French
inventor has made a successful trip in
a new steam carriage from Paris to
Lyons.
-Creosote has been successfully APP
piled as a remedy for the potato disease
in Scotland. Every eye of the seed po-
tato is touched with creosote by means
Of a small camel's hair brush. The prod
uct Of potatoes so treated is almost
totally free from disease. Where the
creosote is not applied to all the dyes of
the Seeding the result is partial disease.
IL too much is used the seed will not
terminate.
From tables made by the use Of
%synoptic charts, eliminating local dis
%turbances, DIR. G. Meyer believes he has
accomplished what other investigators
have sought to do without success
shown an influence of the moor on the
weather. The height of the barometer,
in the months Of September to January.
Is lowered at the time of full moon and
raised during the first quarter. No
effect can be traced for other months.
Prof. Carl Lumholtz. tho noted Nor
wegian explorer, has completed, under
the auspices of the American Geo
graphical Society of Now York, the
organization of a large expedition to
New Mexico and Arizona. 1t contains
scientists, archPologists, ~botanists, and
biologists, and Professor Libbey, geog-
rapher and mathematician OF Princeton
University, will bo in tho company.

1t is probable that in the near future
the electric light will be used in tho
stereopticon to project lantern slides
on the screen. DIR. L. II. Landy, OF CO..
lumbla College, has devised and uses
most successfully an electric lamp. The
advantage of the arc light for projection
lies in its intensity, Wilderness and paral-
lei rays, as we'll as its small cost per
candle power. The intensity of the
light, when the carbons are arranged
for projection Is from 200 To 1900
candle power. These lanterns can also
be used with much better effect in the
large public lantern slide exhibitions
than the usual magnesium or other
similar lights.
