  It 
  is 
  somewhat 
  noteworthy 
  that 
  eight 
  out 
  of 
  the 
  ten 
  species 
  identified 
  should 
  be 
  

   found 
  in 
  such 
  a 
  circumscribed 
  area, 
  and 
  this 
  illustrates 
  in 
  a 
  convenient 
  way 
  how 
  an 
  

   estate 
  can 
  be 
  invaded 
  by 
  mosquitos 
  when 
  situated 
  too 
  near 
  to 
  jungle 
  or 
  swamp.
