THE RAINFALL OF OCTOBER. 



October, this year, has given a quarter of the year's 

 rainfall. During the same year there were 223 wet days — of 

 this number October contributed 30. That is, this month 

 gave 13 per cent, of the wet days instead of 8 per cent. 



The average rainfall for each month has been worked out 

 for the whole period of forty-seven years, and I now give this 

 in a tabular form with the highest and lowest falls in each 

 month. This table will be useful for future reference and is 

 worth preserving.

The driest month is June and the wettest October, 

 average number of wet days in each month show 



The 

 that 



October, November and December are equal, but that October 

 has the highest number in common with the others. The 

 table, however, shows an exceptional instance in which the 

 month of December in the year 1876 gave a higher record 

 than that of any month of October, the figures being : 

 October, 1872— 1104 in.; December, 1876—11-47 in. 



October's position comes out strongly in the minimum 

 falls, its driest year giving 129 (1866) against 0'99 the next 

 (January, 1858).
