country with open forest and a stream nearby. You should endeavor 
to obtain representation of as many of the species of birds as may 
occur here, as may be practicable, following the lines of the collect¬ 
ing that you and 1 have carried on together in eastern Panama for the 
past two seasons. I expect to come down myself to join you toward 
the end of February when we will work together. 
1 have given Dr. Zetek a credential for you covering the 
Canal Zone Biological Area so if there is any delay in your plans, 
or for any other reason it seems desirable, you can go to Barro 
Colorado Island for whatever period may be desirable. 
Your letter of authorization covers the hire of an assistant, 
such as we have had in our previous work. 
I wish you all success in this investigation. Looking forward 
to seeing you in the field in February, I am 
Sincerely yours. 
A. Wetmore, 
Secretary.
