  Rot-holes

  Rot-holes 
  in 
  trees 
  are 
  a 
  most 
  prolific 
  source 
  of 
  mosquitos, 
  and 
  for 
  this 
  reason 
  have 
  

   attracted 
  the 
  attention 
  of 
  sanitarians 
  ; 
  they 
  are 
  equally 
  objectionable 
  as 
  a 
  source 
  of 
  

   biting 
  midges 
  and 
  other 
  insects.
