1t is said that in the case of heavy
vehicles, such as motor carria ges, the
principal source of wear and destruc-
tion of the pneumatic tires is not pune
turing or breaking, but internal strain
and friction. In some tires the interior
tibers of the rubber have been found
reduced to fine powder by the con-
stant wear.
The Agricultural Department has
constructed a new building at Wash
ington 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-foXtail seeu from Germany.
costing 80 cents a pound, was adulter-
ated more than 20 per cent. with seed
worth only 10 cents a pound. Orchard
grass, purchased in the open market,
was more than half bad. Some Grim
son clover. similarly purchased, was 9S
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 it takes
ton of shot to kill one man. For in
stance, it has been estimated that in the
Crimean war the British and French
troops fired between them the enor-
nous amount of 100000 projectiles,
resulting in the death of only $1,000
Russians, while on their side the Cars
adherents killed some 10000 of the
allies, with an expenditure of over So
100000 projectiles this representing a
death for every LOST shots fired.
After an experimental study of more
than five years at the psychological
laboratory of the Saltpetrere, 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-s,x
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
once had numerous fresh-water lakes
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 muu 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 floated 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 writers
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 drec-
tion of the forearm. back toward the
flank. Meanwhile impart to the wrist
land forearm) a 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 fiat scrawl." The
movement can also be taught, with rel
qtiye facility to the left hand
