KEDZIE. In the monthly tables of observations the observations are recorded as taken at 7 A. M., 2 P. M., and 9 P. M., daily. THERMOMETER IN OPEN AIR. This is intended for the register of the thermometer, and for the daily mean or average of the three observations. RAIN AND SNOW. Under this head are entered the time of beginning and ending of the fall of rain or snow, and the amount, in inches and hundredths, of rain or melted snow collected in a gauge at the surface of the ground; also the depth of the snow. CLOUDS. Under this general head are entered three daily observations on the aspect of the sky, etc. The "Percentage of cloudiness," designated by figures; 100 being entire cloudiness; 50 half cloudiness; 0 entire clearness; and intermediate numbers in proportion. The description or "Kind of clouds," is entered by means of the following abbreviations: St. Stratus; Cu. Cumulus; Cir. Cirrus; Nim. Nimbus; Cir. st. Cirro-stratus; Cu. st. Cumulo-stratus; Cir. cu. Cirro-cumulus. WINDS. This is for the record of the direction from which the wind is blowing as indicated by a vane, and its force by estimation. The direction is entered in eight points of the compass: N., N.E., E., S.E., S., S.W., W., N. W. The force is to be estimated and registered by figures from 1 to 10, as in the first column of the following table. The figures in the last column, expressing the number of miles per hour, are not to be used in the register: |
