WEATHER SIGNALS.

Explanation of tlielr Moving BINOLE WEATHER SIGNALS.

Number 1, white ting, six feet square, always indicates clear or fair weather, do rain. . Number 2, blue Hag, six feet square, indicates rain or snow. Number it, black, triangular Hag ' "ilte feet nt the and six feet in length, always refers to teiuperaf ture. When placed above numbers lor 2 it indicates warmer weather; when placed below numbers 1 or 2 it indicates colder weather; when not displayed, the indications are that the temperature will remain, stationary, or that the change in temperature will not vary five degrees from the temperature of the same hour of the proceeding day. ( Number 4, cold wave flag, six feet square, with black center, indicates the Approach of a sudden and decided fall in temperature. This signal is usually ordered at least 24 hours in advance of the cold wave. It is not displayed unless a temperature of 45 degrees, or less, is expected, uor is flag number 3, displayed with it. When two~orihree flags are displayed, in combination, the one highest cm the pole indicates jthe weather to be expected first and the flags lower clown indicate the weather to come later. Various combinations are sure to occur, but the one thing most necessary to bo ..remembered, after fixing in the mind what each flag indicates, as explained above, is to read the signals from above downward.

We give some combinations that are likely to occur: I Black above white, warmer, fair ———- —— - White above black, fair weather, colder. . . IE the white, blue, black and p white with black center hags were ; all displayed at once, the white I' highest, and the others in the or- \ der named, the combination would i indicate fair weather, followed by rain or snow, colder, with a cold wave. A mixture of weather often L experienced in this latitude. As we have previously re mar k- | ed, the white, fair weather signal does not necessarily indicate- elect r [ weather but simply weather free i from rain or snow, whether it be | clear or cloudy. The cold wave signal does not, mean a regular Dakota blizzard, nor anything similar | thereto, but it means, at least, a I sudden and sharp decline in temI perature of 15 or 20 -degrees, or I more. We advise all our readers who fpwish to understand the meaning of these weather signals, to cut out l this explanation and study it until |$ they understand it.
