Speed of Cannon Ball Fired

Fast Moving Train Pre

By CARKETT P. SEUVISS.

topics of a problematical nature, my
friend brought up a question which I
woilfd' like to" have you answer,' ' as
we. are disagreed.

'Yes, the ball would leave the cannon
wKh arapeed of sixty miles an hour, with
reference to the head of the locomotive,
but Kwould travel 120 miles an hour with
reference to' the ground.. It Is already
traveling sixty miles an hour while it Iff
yet lying In the. cannon, and the Impulse
given It by the powder simply adds an
other sj.xiy miles an hour to ita motion.
If the cannon stood besWe tho track and
was Tired at the instant When the Tiead
the locomotive came up with it, then
the ball (neglecting the effect .of air re
Mlstancc) would Just keep abreast of the
fpcomtrtlve, because each would have the
same velocity.
If you- reverse the case and suppose
your cannon flrej froth the rear end of
trje train, then the cannonball and the
train would separate at the rate of sixty
miles: an h'our, the forward motion of
fluj ball (with the train) being exactly
neutralized.
AU'.6r.' these problems depend upon
Newton's "laws of motion," which ex
perience has proved to be correct. - The
thing to remember is that if a body in
motion, nan more motion in the same di
rection imparted' to It, velocity 'Is added
to that-wMch it already possesses, but
the original motion in. no way or .degree
subtracts from the effect produced by
the added motion.
Jf this . were not so, a ailing body would
not continue to Increase its velocity The
force" 'of' the earth's attraction, or
gravity, is . sufficient to cause -any body
falling hear its surface to acquire a
velocity of about thirty-two feet during
each -second that it continues to fall. If
you should tumble from the top of the
S,ool worth tower In Broadway you would

second, and at tho end of that sec
ond you would be plunging downward
with a velocity of thirty-two feet per
second. During the next second you
would acquire an additional velocity of
thirty-two feet, making sixty-four In all,
ami the distance that you would havo
fallen during those two seconds would
be' sixty-four feet - During the third sec
ond your total velocity would be In
creased to. ninety-six feet' whllo the ins
tance fallen -In three seconds wonld be
144 feet. Supposing the Whole height to
be Sij feet, ' you would be about six 'arid
a half seconds In reaching the pavement.
and you would strike with a velocity of
about 208 feet per second, quite suf
ficient to lcstroy all Interest In terrestrial
mathematics.
"If a cannon were fired from a boat
In the ocean, and the camion were made
level by the use of a spirit-level, would
the bullet. If It had power to go on with
out loss of speed, or change of course
whatever, finally hit the crest. How Is
an object made level? It. It. W., Col
Chester. 111."
If you mean by "the crest" the horizon,
or the line where tho sly seems to meet
the sea, then the projectile would not
touch it. but would pass above It, at' a
height depending upon the distance Of
the horizon, which, Irt turn, would dp
rend upon the elevation of your eye
above the sea-level. A common rule for
finding the distance of the hoi lion at
sea, or "on a level prairie, is this: To the
height of your eye. In feet, add half that
height, and the square root of the sum;
the result will be the distance In miles.
This rule gives for a height of 6lx Yeet
a horizon distance of three miles. A can
nonball fired on a level, from a height of
six feet, would pass about twelve feet
above the horizon, situated three miles
away.
If the cannon could be supposed fired
in such a way that the ball would just
fckim the surface of the water in start
ing on its straight course, then at a dis
tance of one mile from the starting point
It would bo about eight Inches above the
surface; at three miles Its height would
be six feet, and at twelve miles ninety
six feet. Its course would be "tangent,"
which Is a line touching tho circumfer
ence .of a circle at a right angle to the
radius at that point,- a -radius being a
straight line from the center of a circle
to any point on Ita circumference. Tho
plumb-line shows the direction of the
earth's radius at any place. What we
call a level is a line, or plane, lying In a
tangent to the earth's surface, or parallel
to sucty tangent, and' consequently at a
right angle to radius or the direction of
the plumb-line. The spirit-level Is the

John Moore walked straight to Bobbie

Bobble slowly straightened.

"June has decided not to see any of you
Just yet and she Won't!"
. Iris took two letters from the mantel,
. tho gave one to 'Ned and one to Mrs.
Moore. - Her husband looked over her
shoulder. The ' letter was addressed to
"Dear Haddy and Mummy I ' cannot
explain in a letter why I was compelled
to leave Ned. Soma day I will make
yon understand and forgive. Please be
good to dear Ne! and love

"Here's the man:" shouted Ned. his
t voice full of sudden fury. ,- lie held a pair
of gloves in one hand and a card in the
othefv--'These, are June's gloves. They
were lying -on the table, and tho card
' was In them!"
"They're my . gloves!" called Iris, but
Ned laughed at her. There was no nila
taking those dainty, blue embroidered bits
of whits kid.
"Now, m tell you." went on Ned.

- now know for the first time, was with
, her from the moment she left me until
she came here. He la a tall, black Van
dyked man, and at Farnville he was seen
assisting June on the down train. I saw
thtjm -myself through the ar window
talking together. I want to find Gilbert
Wye! Are you hiding him too?" And he
turned savagely on Iris.
. Bobbie lounged forward. "Ttiat'll do,
Ned," he warned. "Iris, call June."
"Janle!" .They found Iris throwing
doors-itpen and- running through the
house, ealty.ig June. Ned darted up the
ktaJrs. but in the ball Iris met hint with
a frightened face. "She is gone:'
They 'all seacbed for her then, but there
was no trace of her.

I'ear .Minn Kalrfax: I am Uf. and, en
gaged to ii nlrl seven years my Junior.
Now. 1 (lenrfy love this girl and could
not live without her, an.1 I am sure she
return my affection, but when we are.
out, together she always flirts with other
young men and it is embarrassing. Now,
how can I stop this? HAM W.
Have a serious talk with this girl.
Tell htT that you are not Jealous and that
you do not suspect her of any wrong In
tentions, but that you feel It puts you
In a most undignified position when she
goes out with you and flirts with other
men. Ask her not to belittle you and
your love for each other. In . this way.
Tell her you arc sure she was only
thoughtless and will stop now that you
ask It of her.
The self-poised young man usually starU his-love suit Irt a most cor
rect faahioD, choosing Cupid for his counsel. Although' the verdict
must come from the girl he loves, whose bright eyes have so bewitched
him, ho realizes that the jury is most important. In-a masterly fashion
he wins over her friends, one by one. Yet at -the last moment, when
victory seems near, wild panic seizes him.. In vain does Cupid assure
blm he has won. and black gloom settles over him like a mantle; Well,
he realizes that for his happiness this is the court of last appeal, and In
despair he throws himself on the merry of the court. If he could only see
her eyes, and the little smile hiding Jin the-sweet curves of her Hps,
how quickly would his suspense and Bi leery disappear!

Blye returned on an early train?"
"Yes." Ned tried not to speak curtly.
"I saw hlin."
"I am Mrs. Blye. Is there anything I
can do for you?" the lady was studying
the group with a screwlike penetration.
Mrs. Blyo began to worry herself. Also
she' began to suspect! That lost was her
specialty. Vlfyou.will tell me the. nature
of your business with Mr. Blye 1 may
b able to locate him." ..
"I want my daughter!"' blurted John
Moore, his lira squaring.
"Oh!" And Mrs. Blye's voles rose,
"Your daughter!" She glared at them for
a moment. "Will you please wait?" sho
asked and sailed back through tho hall.
They could hear her sharp voice tele
phoning. Hhs had her husband's club,
and they heard, her exclaim iudUnantly,
"Vhere, Sherry's?" 3ho was back, bias
ink. Sho had her hat In her huud. "Us's
at Sherry's!" she shrilled.

Several weeks ago I took a girl to dinner
and to the theater. New, I care nothing
for this girl ami merely took her nut fnr
an avenlng's amusement, but alnce then
she bus hern eonatuntly 'phoning to me.

do. , THOMAS D. T.
Tell the girl in a quiet, dignified1 man
ner, which she will have to believe, that
you cannot be disturbed at bualnsss and
that you will not come to the 'phone if
she calls you again. Also add that yon
will call her When you have anything to
say to her, and that you hope she will
feel that she respects your attitude and
determination.
