This table shows, as previous ones have done, that the 
heaviest falls of rain happen as the movement of the air 
increases. Though on carefully examining this and other 
tables I have produced, there is a limit to' this law. The 
maximum of fall with high wind appears to be attained 
when the wind moves at an average rate of about 12 miles 
per hour. The ratio column shows, what my other tables 
have done, that about three quarters of the amount of rain 
for the year falls at the height of 34 feet above the ground. 
The next table represents the rainfall during the day 
time of each month, or from 8 a.m. to 8 p.m,; and during 
the night, or from 8 p.m. till 8 a.m.
