In the next table I give the fall of rain during the day 
from 8 a.m. to 8 p.m., and the fall during the night from 8 
p.m. to 8 a.m. The coldest months give a greater rainfall 
during the night than the day. This is somewhat reversed 
in the spring and summer months, June and August show- 
ing an exception.
