Perhaps the most frequent question
asked of a baseball writer Is, How
far can a ball be made to curve?"
OF course they mean by a normal

sweeping and widest fast curve ball

We placed IL big sheets Of tissue

In front Of the plate, the rest scatter
ed at wider intervals until the last
one was feet in front of the pitchers
slab, and, to my surprise, his hand
struck the paper as the ball was re-
leased, proving the actual distance
of the pitch is much shorter than
usually supposed. OF course Over

the average, but do not think the act

plate, is more than Sc feet
Overall pitched his wide overland
curve. The ball entered the first
sheet four feet to the right of the
string, which was placed through the
center of the two plates at height of
five feet, and almost six feet above the
ground Che was pitching off slight
elevation). His hand hit the paper
and tore a hole a foot lower, showing
he had released the ball before his
arm reached the extreme limit of its
swing. The ball went through the sec
ond sheet, which was 10 feet from the
first just four inches lower than
through the first, and little over
two and a half feet from the right OF
the line. 1t was less than a foot from
the line when 1t struck the first Of the
eight sheets placed closely together in
front of the plate, and it tore through
the next one trife higher Then it
began its true curve. Nine feet in
front of the plate it broke" and shot
downward and outward and crossed
the sheet at the home plate ten inches

inches to the outside" (that Ii, for a
right-handed battery Of the center OF
the plate The ball had dropped FIVE
feet two inches downward, through the
force Of gravity, the angle at which 1t
was pitched and the curve, and had
angled and curved practically five feet.
The closest calculation we could make
was that the ball actually curved, as
a result Of its rotary motion, approx.
mately II inches.
The air resistance, which was dis
puted at Tyng's experiments, has, OF
course, became known factor with
the study of the science of aeronaut
les. The amount of resistance can
be computed closely by the use Of the
barometer. The ball curves in the di
rection in which it revolves. The
amount of the curve depends upon the
