pear Aldo, 
 
   Thank you for the large group of reprints and for the 
 
newsletter which just arrived. This is the busy sepson 
 
and I have nit yet had time to go over them in detail. 
 
 
     I am enclesing a copy of   the spring report on the 
 
duck flight which I am sure you will be interested in. You 
 
would hardly recognize this marsh here as a breeding ground for 
 
wayerfowl anymore, the ducks are so few. 
 
 
 
 
                           Sincerely,
