immense excess of the average fall. From the table given 

 below this excess will be seen to be more than 13 inches, or 

 about 3G*7 per cent, over the average fall of the year. 

 There were only two months of the year, August and De- 

 cember, that had a fall less than the average of twelve 

 years, but this minimum was exceedingly small. The 

 greatest excess above the average happened in the summer 

 quarter, July to September, and the fall in July was 142 per 

 cent, above the average for that month. June, July, and 

 September were the wettest months of the year. 



The number of days on which rain fell during the past 

 year was very large. There were only 101 days throughout 

 the 3'ear on which rain did not fall. There was 27 per 

 cent, over the average of twelve years of days on which rain 

 fell during the year. But the number of wet days ex- 

 ceeded the average most in the first six months of the year. 

 The number in excess in the first three months being as 

 much as 34 per cent.
