December, 1888 — This month, for cloudy weather and the number of days 

 it rained, has exceeded any December since 1884. The mean temperature 

 was 50.2°, nearly 2° below the average for the past five Decembers; the 

 maximum was 66°, 4° below the average, and the minimum 35°, an average 

 for this month. The highest barometer was 30.28; lowest, 29.47; mean, 

 30.041. Number of clear days was 13; this was below the average for 

 December. Cloudy days, 17; two above the average. Fair days, 1 ; three 

 below the average. There were 12 rainy days — on the first, eighth, ninth, 

 tenth, thirteenth, fourteenth, fifteenth, sixteenth, twenty-first, twenty- 

 second, twenty-fourth, and twenty-sixth, a trace on the eleventh, twentieth, 

 twenty-fourth, and twenty-ninth. Rainfall for the month, 8.91; and for 

 the season to date, 13.75. Last season to this date, 3.99; excess this sea- 

 son, 9.76. There was two light frosts this month, on the thirtieth and 

 thirty-first, thermometer at 38° and 35.5°. Prevailing winds, southerly. 

 Number of days from south, 8; southwest, 7; west, 6; northwest, 1; north- 

 east, 2; north, 1; east, 1. The daily weather predictions received at this 

 station from Lieutenant Maxfield, Chief Signal Officer, San Francisco, for 

 the month of December, have been verified in all except two instances, the 

 fifteenth and twenty-fourth of the month. This shows over 92 per cent of 

 the predictions verified. This we consider extraordinary and highly cred- 

 itable to that officer. It must be remembered Oroville is out of the direct 

 line of telegraph communication with that office, and not permitted to 

 frank telegrams to the same. Our people watch my bulletin board for the 

 daily predictions, and a short time after they are posted it is known over 

 the city the state of the weather for the next twenty-four hours.
