SCIENCE AND INDUSTRY.

Pomona, Cal, this year, was from
grove of trees seventeen years old. Six
acres yielded $500 boxes. Two trees
yielded thirty-fve boxes.
Wood pulp is rapidly becoming one
of the most universally used Of manu-.
featured 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 collins in which

If child cries because he goes tc
bed in the dark he must he humored
and given light, according to the
latest scientific theory. Modern psy-
biologists have discovered that chill
dren are subject to Authorizations, and
that their imagination that they ''see
things" is very vivid and real.
Florida shipped her first phosphate
in 1889 and in 1891 mined isl. 44S tons.
Algiers and Tunis have newly found
phosphate deposits away from rail or
water communication estimate at w.
OO0.0 900 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 SkSgit will turn out 25,-
600, 600 feet of fir logs alone this year
Every province in China contains
coal and it is really one of the first coal
countries in the world, but it imports
almost -, 900. 900 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 800. 900 tons: France and
Belgium next, each $50. 900 tons: Florida
next, 100000 tons; Russia, $4,000 tons;
Spain and Germany, 80, 900 each; Dutch
West Indies, 10000; English West
Indies. 10000; North Carolina, 1900;
Algeria, $500.
shrink from the hand which tries to
seize it, and if viewed under lens may
be seen constantly drawing in water
through the innumerable canals which
form its digestive organs, and having
consumed the minute animalcul8 in
the fluid, ejecting it again through
some other channel.
Charcoal is valuable as fuel, but it
has other uses which make it one of
the most serviceable of articles. When
laid fiat, while cold, on burn, it causes
the pain to abate; by leaving it on for
an hour the burn seems healed when
the wound is superficial. Tainted meat
surrounded with it is sweetened. Strewn
over heaps of decomposed pelts, or over
dead animals, charcoal prevents I'M
pleasant odors. Foul water is purified
by it.-Age of Steel.
-Pleuro-pneumoni 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 to completely extirpate it. The
time required was about five years,
and the total expenditure little in ex-
cess of $1,000. 600
How water, commonly called sap,
necessary to the life of a tree, passes
from the roots to the topmost leaf and
evaporates is a problem not yet solved
by botanists. 1t is known that the
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.
Beyond is mere conjecture, and every
theory vet advanced has failed t. stand
the test of experiments.
insects do not breathe through the
nose and mouth. Down the body run
two main pipes These pipes send out
branches to right and left like a net
work, extending to the extremities,
even to the ends OF the antenne and to
the claws. Each main tube receives
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
hair, which completely guards the en-
trance.
In England 100000 velocipedes are
turned out annually. In Coventry 49,
600 worlSmen are employed in the bust
ness. In France, where the machine
first appeared, its use was limited
through prejudice; people laughed at
it. Now there is an army of 100000
proprietary wheelmeu in that coun-
try. without counting the immense
number of amateurs who hire ma
chimes. In 1892 the Paris police author
tiles issued $4,000 Licenses to wheelmen,
now the number y velocipedes is esti-
mated at something over $4,000. In
1928, 60, 900 machines were sold, and
it is believed that at least one-half of
them are used in the city alone.
