  Phelps, 
  in 
  

   Ottertail 
  County, 
  would 
  make

  There 
  are 
  two 
  of 
  the 
  recommendations 
  which 
  possess 
  especial 
  

   importance: 
  First, 
  to 
  preserve 
  by 
  artificial 
  propagation 
  the 
  types 
  of 
  

   shells 
  shown 
  in 
  the 
  muckets 
  of 
  Lake 
  Pokegama 
  and 
  the 
  pocketbooks 
  

   of 
  Menahga; 
  second, 
  to 
  improve 
  the 
  opportunity 
  so 
  favorably 
  offered 
  

   at 
  Lake 
  Minnewaska 
  and 
  thorouglily 
  try 
  out 
  by 
  experiment 
  the 
  

   introduction 
  of 
  valuable 
  commercial 
  species 
  into 
  lakes 
  that 
  are 
  

   specially 
  suited 
  to 
  them.
