 the month was 25.7 degrees which is 

 :!.:> degrees below the normal and the 

 lowest for December since 1906. The 

 ■ igbest temperature reached was 'M 

 degrees on the 6th and the minimum 

 of the month was one below zero on 

 the aist. More than one-half the pre- 

 cipitation was in the form of snow, 

 20 inches falling, 18 inches coming 

 during the" storm of the 2rith-2Gth. 

 The total snowfall was nine inches 

 more than the average amount and 

 the greatest in December since 1901. 

 1.6B inches of rain fell during the 

 month, the most in one day being 1.29 

 inches on the 14th.

 of relative humidity and there was 

 less cloudiness than is customary. 

 The total amount of sunshine was 

 15 per cent, greater than the average. 

 There was more than the normal 

 amount of wind, the mean velocity 

 being the highest for December since

 miles per hour from tho northeast 

 on the 26th. The prevailing wind di- 

 rection was west and there was a 

 marked absence of south and east 

 winds.

 the year and an excess of sunshine 

 during most of the months. The 

 mean lemperature for the year was 

 41 J] di-grees, o.S degrees warmer than 

 the normal and the highest since 1906.

 corded. 1909 was the windiest year 

 since 1897, January, September and 

 October being the only months with
