1t is said that In the case of heavy
vehicles, such as motor carriages, the
principal source of wear and destruc-
tlon of the pneumatic tires is not pune
turing or breaking, but internal strain
and friction. In some tires the interior
fibers of the rubber have been found
reduced to u fine powder by the con-
slant wear.
The Agricultural Department has
constructed new building at Wash
lngton to be used solely for testing
seeds of all kinds, In order to afford pro-
lection against dishonest dealers. Re
cent tests gave remarkable results.
Meadow-foxtaii seed from Germany,
costing 35 cents pound, was adulter-
ated more than 70 per cent. with seed
worth only 10 cents pound. Orchard
grass, purchased In the open market
was more than half bad. Some GRIM
son clover, similarly purchased, was 0S
per cent. bad.
AS Is we'll known, the soldiers risk
of death in battle is not nearly as great
as of finding a grave as the result of
disease. The most competent authori-
ties state that on the average 1t takes a
ton of shot to kill one man. For In
stance, 1t has been estimated that In the
Crimean war the British and French
troops fired between them the enor-
nous amount Of 45,000,00O projectiles,
resulting In the death of only $1,000
nrc hot ct 10 tta ne
adherents killed some 10000 Of the
allies, with an expenditure of over co.
100000 projectiles this representing
death for every LOST shots fired.
After an experimental study Of more
than five years at the psychological
laboratory of the Saltpetriere, Nj. Vas
chide has concluded that the brain is
always active, and there is no such
thing as dreamless sleep. He has
watched the sleep of thirty-six subjects
ranging in age from twelve months to
eighty years, and his own observations
have been checked by those Of forty-slx
other persons. He finds that the dreams
of deep sleep differ from the hallucina-
tions that come at the moment of fall
ing asleep and that of waking. The
superficial sleep reflects more the SEN
sations of every day, while the dreams
of deep sleep are more continuous, more
logical, farther from reality, and have
more to do with ones earlier existence.
Biologists are Of the opinion that the
vast territory now known as Wyoming
hod IL
and climate approaching the semi
tropical, and that the animals whose
bones are from time to time coming to
light inhabited these lakes and the ad-
Joining swamps in myriads. They sank
into the mud In dying, and their bones
were covered with other deposits and
became petrified. The large beds are
found at points supposed to have been
the mouths of great rivers, the animals
after death having f1oated down these
rivers to places where they were de-
posted in these estuaries, thus account
ing for the vast deposits which charac-
terize certain localities and which have
proved such study to scientific inves-
| tigators.
Prof. R. s. Woodwork describes in
Science a new movement for writer's
with the pen which, he thinks, has
decided advantages over older methods.
To write In the new manner, let the top
of the paper slant to the right instead
of to the left. The horizontal lines
across the paper can then be followed
by drawing the whole arm, In the direc
ton of the forearm, back toward the
flank. Meanwhile impart to the wrist
| land forearm) back and forth lateral
motion which shall produce the vertical
strokes of the letters" When this
method has been mastered, Prof. Wood
worth says, rapid writing is freer and
more legible, showing no tendency to
degenerate into the fat scrawl." The
movement can also be taught, with rel
atlve facility, to the left hand.
