to 1862, exceeds the totals for the subsequent years. The average 

 number of days each year when rain or snow falls is 92 ; or almost 

 exactly one day in four. The greatest number of rainy days occurs 

 in May, and the least in September, Comparing Table XIII with 

 Table XI, we see that the amount of the rain for diiFerent months is 

 not exactly proportional to the number of rainy days ; for while dur- 

 ing the three winter months the number of days of rain or snow is 

 somewhat greater than for either of the other seasons, and is decidedly 

 greater than for the autumn months, the amount of the precipitation 

 is sensibly less. 



The following Table shows the cases in which the fall of rain was 

 unusually great. The extraordinary rain of October 3d and 4th, 1869, 

 caused an extensive flood, which occasioned no little destruction of 

 property.
