The Honorable, 
The Secretary of State, 
Washington 25, D.C. 
Sir: 
I beg to advise that early in February 1 expect to go to the 
Canal Zone on official business for the Smithsonian Institution, 
and that while there I plan to continue my scientific studies 
concerned particularly with birds in the Republic of Panama. 
The work is in continuation of other similar investigations that 
I have made during the past five years in that area. I will be 
accompanied by Mr. W. M. Perrygo of the United States National 
Museum, as assistant, and will expect to spend about seven weeks 
in the field. 
My studies will be entirely scientific, and will be in continuation 
of work relative to the ornithology of Panama that I have carried on 
since 1944. The results will be published ultimately where they will 
be available to scientists in Panama and in our own country. The 
work, as indicated above, is official on behalf of the Smithsonian 
Institution and the U. S. National Museum. 
It will be appreciated if the American Mission in Panama City 
may be requested to inform the appropriate department of the 
Republic of Panama on behalf of the President of Panama of my 
proposed visit. In my earlier studies I have had the honor of a 
certificate from the Minister of Foreign Affairs recognizing our 
work. No other facilities are required. 
Your kind assistance in this matter will be most helpful. I am 
Respectfully yours. 
lp 
A. Wetmore, 
Secretary.
