As most of our readers have doubt
less noticed, flags are now daily dis
played upon the mast ofour High
School Building, indicating the
Forecasts" of the weather and tenn
perature, as made by the State Wea-
ther Service Bureau at St. Paul. Ar
engagements for these signals and the
equipment Of volunteer station have
been made by our village council; the
observations, reports, ETC., will be
undertaken by the pupils of the High
School. These forecasts of the
Weather Bureau are prepared from
the ga. m. observations taken atvari-
GUS points in this and neighboring
states, and directions for hosting the
proper signals are telegraphed to us
about 10 a. m. daily. The flags will
be displayed from about 1880 a. m.
to 4:8O p. M, and will indicate the
weather for the following twenty-four
hours.
The following is quoted from the
official circular: Weather forecasts
are telegraphed to observers atstations
of the Weather Bureau, railway otti-
Gals. and to many others, and are SO
worded as to be readily communicated
to the public by means of flags. The
flags adopted for this purpose are five
in number.
Number l, white flag, six feet
square, indicates clear orfair weather
Number 2, blue flag, six feet square,
indicates general rain or snow. No. 3,
parallel bars of white and blue, six
feet square, indicates that local rain
or snow will occur, and that the
rainfall will not be general. Number
4, black triangular flag, four feet at
the base and six feet in length, always
refers to temperature; when placed
above numbers l. 2, or 3, it indicates
warmer weather; when placed below
numbers |, 2, or three it indicates
colder weather; when not displayed,
the indications are that the tempera-
ture will remain stationary, or that
the change in temperature will not
vary more than four degrees from the
temperature of the same hour of the
preceding day from March to Octc-
Der, inclusive, and not more than six
degrees for the remaining months of
the year. Number S, white flag, six
feet square, with black square in cen
er,indicates the approach Of sudden
and decided fall in temperature. This
signal is not to be displayed unless it
is expected that the temperature will
fall to forty-two degrees, or lower, and
is usually ordered at least twenty
four hours in advance of the cold
wave. During the late spring and
early fall the cold wave flag is also
used as a frost-warning flag to ind
cate anticipated frosts. When num-
Der 5 is displayed, number 4 is always
omitted. The signals should be read
