lakes shows where rain has fallen
during the past "a hours and where it
has been dry. A picture like this has
been made each morning for nearly
so years and even the most careless
study of these pictures will show at
once that all our weather conditions
travel across the country from west
to east in an endless procession.
By a more careful study of these
pictures, or weather maps, as they
are commonly called, the forecasters
of the bureau have learned that in
this great eastward movement there
are many Irregularities in both
directions and speed and that these
changes in direction and speed can
usually be foretold number of hours
in advance. Having learned how to
foretell the probable movement of
general weather conditions it is pos
sible to forecast for any locality what
the weather is likely to be for the
next "a to AZ hours. By means of a
simple cipher and a carefully devised
scheme of Geographic circuits the
data recorded at 8 o'clock at all the
stations throughout the country are
collected at the forecas centers and
entered on a may in about an hour
and within two hours the forecast
has been made and sent out by tele-
graph, telephone and mail to every
corner of the country.
OF course, the forecast now and
then proves to be incorrect, but the
percentage of failures is small and
this forecast is far more accurate
than any that can possibly be made
in any other manner. In addition to
the daily forecast a weekly forecast
is made on Saturday night based on
reports received from Alaska and the
islands of the Pacific. This forecast
is not definite like the daily forecast, |
but gives with reasonable accuracy
the general conditions that may be
expected for the following week. |
The farmer who makes intelligent !
use of these two forecasts can un-
dOubtedly make savings here and |
there that will amount to many dol
lars in the course of year.
Here are few ways in which many
farmers are already using the fore
cast and saving money thereby: In |
haying and harvest time the careful |
farmer does not cut his grain or hay
until there is a reasonable prospect
for fair weather to continue until the
crop can be taken care Of He does
not kill his hogs until he is sure the
cold weather will last long enough to
cure his meat. In fact, all of his
operations are more or ess influenced .
by. the weather and his plans for to-
morrow must be based on some kind ,
of weather forecast. The question
then arises, what forecast shall he :
use. Shall he depend on his own OBJ i
alone or shall he supple
ment it and strengthen it by using
The data offered by the weather bu-
reau? t
The forecast of the weather bureau
will be delivered to you each morn
ng free of charge. Wry not try
hem out and save some money for
Yourself? {
Although the weather bureau be-
Ongs to the department of agricul-
ure, its forecasts are used by people
n all walks of life and for all sorts I
If purposes great and small. On the
coast hundreds of great ships are .
Kept in port to await the passing of c
| predicted storm and millions of Z
dollars are saved. Along the great Y
'ivers of the country timely warnings r
If floods save other millions of dol :
ars and in both cases many lives are ;
During some of our cold
waves millions of dollars worth of +
produce and fruit are saved by those +
Who heed the cold wave warning.
You may think that these are all o
