  Fog 
  clearing 
  up 
  early 
  means 
  a 
  fair 
  day; 
  fog 
  persisting 
  implies 
  

   that 
  there 
  probably 
  will 
  be 
  rain 
  later 
  in 
  the 
  day, 
  or 
  during 
  the 
  coming 
  

   night. 
  As 
  the 
  proverb 
  puts 
  it 
  : 
  

  

  " 
  Mists 
  dispersing 
  on 
  the 
  plain 
  

   Scatter 
  away 
  the 
  clouds 
  and 
  rain 
  ; 
  

   But 
  when 
  they 
  hang 
  on 
  the 
  mountain 
  tops 
  

   They'll 
  soon 
  descend 
  in 
  copious 
  drops."
