Here the autumn rains appear heavier than any others ; those in mid-winter are 

 the lightest. 



The following figures are from Tables LXXXVII and LXXXVIII of Director 

 Kingston's Results of Meteorological Observations made at the Magnetical Obser- 

 vatory at Toronto, Canada West (Toronto, 1864), derived from twenty-two years 

 of record, ending with 1862.

Here, also, we note a slight increase in the average daily rain-fall in the warmer 

 season, and a slight decrease in the colder season. The above examples, drawn 

 from long records and from stations in different geographical relations, suffice to 

 prove the above assertion as to the nearly uniform copiousness of average daily 

 precipitation, with a slight excess in the warmer months, and a slight deficiency in 

 the colder months, over the average amount. The last table also exhibits the com- 

 paratively light precipitation when in the form of snow. 



The average number of days of precipitation, during a year, are given in the fol- 

 lowing table, arranged according to States and Territories. In compiling this 

 Table only those records were admitted which were continuous during a year.
