"While the mean number of wet days was only slightly in excess 
in the winter months, there was a decided excess in the summer, 
and as decided a deficiency in the spring and autumn months. Of 
the heavy falls that of Sept. 29th was the most general. Falls 
exceeding an inch fell in 4 months, i.e. Feb., June, July (4 days), 
and September, or on seven different occasions.
