OAsaal HAP Made Up from ReDoses

C0Ont1y,

Strictly speaking. our weather bu-
reau is made up of great many build
ings scattered all over the United
States, and the one at Washinton is the
central station that governs ana o1-
rects the smaller ones. and to which
they send in their daily reports; Tor
it is by getting reports from all the
different sections of the country that
Uncle Sans weather-makers are able
to make their predictions. There are
$50 towns and cities in the United
States where there are observation
stations. having the same instruments
and apparatus as the Washington ou-
reau. Now, the Observers At these
$50 stations do not spe0d their time
waiting for spiders to crawl out OF
their holes or looking at the sky to see
whether it IL red or gray in the even
ing. They look At their thermone-
ters, barometers, thermometers, and
so on. which are far better guides than
ali the other signs put together.
At 8 o'clock in the morning and at
O'Clock ih the evening Of every day
the observer at each one OF these
weather stations from Maine to CALI
fornia looks at his different instru'
ments, and carefully notes what each
Of them marks. Then he takes look
at the sky, to see whether 1t is fa1r
or raining OF showing, and to see what
sort Of clouds may be sailing about
According to the weather bureau there
are seven different kinds Of clouds.
and it is important that the observer
should see what particular kind 10 how
| erine around. for each kind means
| some special kind Of weather OF some
| particular, state of the atmosphere,
When he has finished his observation
and noted all the Indications. he tele'
graphs his report to Washington.
In that way. then, the Washington
! station receives an account OF the
weather at all parts Of the country
at the same time. and. as yotl may cas-
ily believe it keeps the four telegraph
operators busy receiving the messages
that come pouring in soon aft
er eight o'clock. AS each mes
sage is received in the telegraph
room it is carried by messer1
ger across the hall to the forecast
room. or room where predictions are
made and handed to the translator
As the translator reads alot1d the
cipher reports from the different sta

what he reads upon a map of the uhitet
States, 50 that when the last message
ha. been translated the map shows
lust what the weather is at each on
of the $50 stations. The map is the1
turned over to the official who il t.

the different places throughout tn
country where the temperature is tn

with red lines and the other with blac

black lines wr1ggling and twisting al
