van  to add to the "objectives' in the agreeents 
 
               "'To wor toward an iatiato authoritative 
          son the ecolog          an managemant of the 
          oanvasbac. 0 
 
          This objective wS    mind but you might prefer it to 
be epeifially state. If so. by all aeanas ad it. 
 
          Tere are other specifie tite we have In mind, but not 
In the paper as it stands. For examle; 
 
               T  exlore the breeding bysioog2 y of the 104al 
          ol to develop oriteria of sex and ae both 
          i    -ternal and extermal; to produce a aaa  on the 
          plum.ges sand nwults of ducks."
