Mr. Alex Wetraore, 
Corinne, tJteJi. 
My dear Wetmorej 
I am glad to have your report on recent work.fl'particularly to note 
that you are making headway on the survey of the aquatic plants. You 
have succeeded in banding a considerable number of birds and should get 
a number of returns from them. One has just come in. I am enclosing 
a copy of the letter about it. I should judge from your report that 
you will have no difficulty in making final recommendations, regard- 
ing the control of duck disease, at the end of this season's work. 
With best regards, I am. 
Sincerely yours. 
Assistant Biologist.
