rain falls have the fewest wet days. Beginning with the 

 month in which rain falls upon the fewest days, we have 

 the following order : May, July, March, April, June, Novem- 

 ber, August, February, January, September, December, 

 October. April, in which the least rain falls, comes fourth 

 instead of first; November, the wettest month except Octo- 

 ber, comes sixth, evidently showing very heavy falls on 

 fewer days ; August and February come next one another, 

 although the former month has about half as much rain 

 again ; December and October are nearly equal, the latter— 

 the wet month of the year — carrying off the palm as regards 

 the number of days pn which rain falls. The number of 

 days on which rain falls is a very important one, as floods 

 are often caused by heavy rainfall falling continuously over 

 a few days during a comparatively dry month. August 

 and November would be evidently months in which to look 

 for floods, from the fact that with a rainfall not far below 

 that of October, rain falls on much fewer days ; this remark 

 refers especially to November, 



Looking at the annual number of days on which rain 

 falls here, viz. a ten years' average of 188 days out of the 

 365, it appears that we have rain on rather more than half 

 the days of the year.
