AVERAGE AIR TEMPERATURES FOR NOVEMBER 



DECEMBER 



Sky: We have an unusually full record for December, cover- 

 ing the month for 1899, 1900, 1902, 1904, 1913, and a good part 

 of 1901. 



December is generally a cloudy month, our observations for 

 every year except 1899 showing more cloudy periods than clear, the 

 excess of cloudy periods usually being considerable. 



Winds: Periods of calm are generally frequent, the weather 

 being as a usual thing pretty well settled and steady. North winds 

 are the least common, those from the southeast the most frequent.
