THE TIME BALL.
Sending Out the Beats From the
National Observatory.
How Clock is Corrected to the Hun
dredth of IA Second - Correcting
Time for $4,000 Miles of
Railroad.

AS the hands of the White House
clock travelling over the dial approach
the hour of noon, the President sitting
at his desk glances involuntarily at
them, for as the sun crosses the seventy
fifth meridian, whatever their varia-
ton during the day preceding, the
clock s hands, impelled by an ingenious
mechanical contrivance, fly sharply to
the perpendicular. And the President
knows, as they fly to their place, that
the ticks of the Executive clock are
synchronous with those of the clocks
of the Naval Observatory. The cleo
trio impulse, for which the Presi-
dent has waited, simultaneously
causes the great ball on the top
of the lofty pole of the Western Union
building in New York to drop, regu-
lates great clock in the Union Depot
at Kansas City; correctly fixes the
hands of the Stock Exchange clock in
New Orleans; effects q similar result
at hundred intermediate points, and
adjusts five hundred clocks in the Gov
eminent departments at Washington.
What would seem to require very
complex arrangement, is, in reality, a
very simple one. Young. but portly
Ensign Myers, of the navy, who, for
two years past, has been the human
cause of this widely -distributede electric
impulse, explained his duties to me the

noon the tests showed that one of the
sister clocks used for distributing the
standard time was within a hundredth
of a second of being correct. The
electric-instrument attachments were
seen to be in perfect adjustment. Mr..
Myers carelessly chatted withme until
few minutes of twelve, and then he
gave a certain signal to the telegraph
company and became entirely en-
crossed. The seconds went by, slowly
and ominously marked by the woodeny-
metallic saunders. | was awed as this
fearfully minute measurement of the
scintillas of time went on. The fiftv-

away from us, were beating in unison
with these in the room where was. |
pictured the crowds of people stand
ing IN Broadway staring up at the
time ball and holding their watches in
readiness; l knew the hum of CONVEX
sation had ceased in a hundred offices.
Took, took, tock,- it was noon, save
thirty seconds. Twenty beats more
were heard; then the last warning was
given. The trees no longer rustled.
A wee bird looked in at the open win
dow-motionless, eXpectant. The clock
showed the last second of the fifty-
ninth minute had passed. An apprecia-
bic pause; there was faint trembling
OF the instruments, a click of the clos
ing of an electric switch. Thousands
of watchers knew it was twelve o'clock
at the Nations Capitol, and the great
clock had begun to mark the seconds
of another day.
The Naval Observatory is built on
one of the crests of the palisades form
ing the northern bank of the Potomac.
1t is short mile directly west from the
Executive Mansion, and the placid pre-
cincts of Georgetown are near at hand.
The main entrance of the building looks
to the north and from it stretches
sloping green swards and through them
twists graveled driveway. Standing
under the spreading branches of the
stately elms that sentinel the tagged
walk, the visitor may read above the
door the following inscription cut in
marble:
