find that the sum—

From this we see that the period of thirty consecutive days of least 
fall of rain is from March 2 to 31, and of the greatest, from September 
28 to October 27. 
By taking the sums of the amounts of rain which fell on every day, 
in periods of sixty days, we find that the sum—

The period of least fall of sixty days’ duration was from March 2 to 
April 30, and of the greatest from August 29 to October 27. 
Again, by taking periods of successive ninety days, we see that the 
sum— 
From January 1st to March 31st was 198-85

But the sum of the falls in the ninety days from January 31 to April 
30, was 192-5 in., being smaller than in the period from January 1 to 
March 31; and the sum of the falls in the ninety days September 8 to 
December 6, was 309’3 in., being larger than in the ninety days June 30 
to September 27. 
Taking successive periods of 120 days, the sums of the falls are :—
