The largest yield OF oranges In
Pomona, Cal, this year, was from
grove of trees seventeen years old Six
acres yielded $500 boxes. Two trees
yielded thirty-five boxes.
Wood pulp is rapidly becoming one
OF the most universally used Of manu-
factured articles. Not only is it found
available for making many of the nee
essaries and conveniences Of mans life,
aside from newspapers, but it is also
appearing in artistic coffins in which
to bury him.
If child cries because he goes to
bed in the dark he must be humored

latest scientific theory. Modern psy-
biologists have discovered that chill

that their imagination that they s.see

Florida shipped her first phosphate
In 1880 and in 1891 mined 1sl ,44S tons.
Algiers and Tunis have newly found
phosphate deposits away from rail or
water communicat ton estimated at 15,-
100000 tons, and Nelson county, vir.
ginia, has small area OF high grade
phosphate ten miles from rail.
Some notion of the vastness Of the
western forests may be had from the
fact that new logging camp just es-
tablished at the headwaters of the
Skagit river, in Washington, is under
contract to turn out an average Of
about million feet every month. Five
camps on the Skagit will turn out 25,-
0OO, 900 feet of fir logs alone this year.
Every province in China contains
coal and 1t is really one of the first coal
countries in the world, but it imports
almost O., 100000 worth of it every year.
1t has also valuable iron and copper
mines and Japanese engineers are now
teaching them modern mining in place
of the ancient methods the Chinese
still employ.
South Carolina is the largest pro-
ducer of phosphates in the world, lead
ing with her 600. 900 tons; France and
Belgium next, each 45O, 900 tons; Florida
next, 10000 tons; Russia, $4,000 tons;
Spain and Germany, $4,000 each; Dutch
West Indies, 10000; English West
Indies, 10000; North Carolina, $500;
Algeria, 2,500.
The sponge is an animal. II will
shrink from the hand which tries to
seize it, and II viewed undera lens may
be seen constantly drawing in water
through the innumerablc canals which
form its digestive organs and having
consumed the minute animalculw in
the fluid, ejecting it again through
some other channel.
Charcoal is valuable as fuel, but It
has other uses which make IL one Of
the most serviceable of articles. When
laid fiat, while cold, on a burn, 1t causes
the pain to abate; by leaving 1t on for
an hour the burn seems healed when
the wound is superficial. Tainted meat
surrounded with it issweetened. Strewn
over heaps of decomposed pelts, or over
dead animals, charcoal prevents un-
pleasant odors. Foul water is purified
by it. Age of Steel.
-Pleuro-pneumonia has been stamped
out by the bureau of animal industry,
according to the report OF Secretary
Rusk on the operations Of the bureau
for the year just ended. The United
States, he says, is the first Of the large
nations of the world which, having
been so extensively infected, has been
able 10 completely extirpate it. The
time required was about five years,
and the total expenditure little in ex-
cess OF 81, 800, 900. 500
How water, commonly called sap,
necessary to the life of tree, passes
from the roots to the topmost leaf and
evaporates is a problem not yet solved
by botanists. 1t is known that the Y
ascent is made chiefly in cavities in the
sap wood only, the heart and bark
serving other purposes. This Is the ex-
tent OF our knowledge Of the matter. l.
Beyond is mere conjecture, and every !
theory yet advanced has failed to stand
the test Of experiments.

the external air through nine or ten
spiracles or breathing holes, placed at
intervals along the sides OF the body,
The spiracles are made water-tight
and dust-tight by strong fringe Of

In England 1900 velocipedes are
turned out annually. In Coventry 49,
900 workmen are employed in the busi-
ness. In France, where the machine.
first appeared, its use was limited
through prejudice; people laughed at
1t. Now there is an army of 100000
proprietary wheelmen in that coun-
try, without counting the immense
number OF amateurs who hire ma
chimes. In 1892 the Paris police author
tiles issued 10000 licenses to towheelmen,
now the number of velocipedes is estl-
mated at something over $4,000. In
1929, 60, 900 machines were sold, and
1t is believed that at least one-half of
them are used in the city alone.
Her Mistake.
"Well,' queried the Third street wo-
man, as she opened the side-door about
an inch and peered at the man ON the
steps.
