through starvation.
rho earth within the Arctic circle
.rnnorts a considerable population, but
M Antarctic circle Is without trace of
srman life. Upon eight million square
lilies surrounding the south pole, the
toot of man has never trodden.
IN the islands near Singapore a new
.,dnstry has been developed, that of
producing pure gutta-percha from the
leaves of the gutta-percha tree. The
leaves are ground up and pounded in
boiling water. Dry leaves contain as
much as II per cent of sap.
Two of the largest Ruhmkorff coils
ever made have been ordered in this
country for a foreign government, and
will give an electric spark forty-fve
inches In length, expanding energy
amounting to three or four-horse pow
er. and having a potential Of half a
million volts.
II Is said that the nut trees OF tAe
world alone could, If necessity arose,
proyide food all the year round for
total population three times greater
than the present. 1t has been pointed
out to the Washington Department of
Agriculture that Brazil nuts around
Para grow In such profusion that thou
sands of tons of them are wasted every
year; with cocoanuts 1t is the same In
many centers.
Every sufferer from nerves knows
that gloomy day affects him unfavor-
ably, while the first ray of sunshine
makes him gay again. 1t has been
suggested that the green of vegetation,
the blue of the sky and the blue-green
Of the ocean may thus have a power
full influence in calming the spirits.
Parville however, cautions his readers
against too sweeping conclusions. All
that we can say is that colors certain

In winter months tornadoes occur
only In the Gulf States, but in Sum-
mer they occur In the North, In Ne
braska, South Dakota, Iowa and Min
nesota. The average is twenty-five a
year. They are simple examples of
vortex motion. A mass Of air rotating
at low level runs into vortex, and
q tube is projected downward. The
velocity of the lower end of the tube
may reach two hundred miles an hour
and 1t Is the partial vacuum caused bv
the whirl and the sudden thrush of the
outside air that causes the disastrous
explosive effects.
Inc black sands containing gold
which are spread along the shores of
Norton Sound, near Cape Nome. Alas
ka, are said to differ from similar
SANDS found on the coast of California
ana elsewhere, because they show no
indication of having been transported
Dy streams of water. The fakes and
nuggets of gold that have been found
at cape Nome are not water-worn, but
fharp and angular in outline, A wide
~ accepted theory is that they have
Deen transplanted from a great dis
lance by glaciers, their original source
Oelng yet undiscovered.
Inc report Of United States Commits
Noner of Labor Carroll D. Wright for
1879 on Hand and Machine Labor"
sets forth some very interesting facts.
Aided by machinery, 100000 men
turn out a product which would re-
auire the labor of nearly 4O,OOO,OOO
Ileh II produced by hand. IN America
pe advantage derived from machinery
8 ABOUT twice as great as In Europe,
80 that the actual population of the
united States is equal in productive
power to 100000 Europeans. With
'aoor-saV1ng machinery, ono general ton
oi men can do the work of four or five
generations of hand workers.
