The Honorable, 
The Secretary of State, 
Washington 25, D.C. 
Sir: 
X beg to write that about the first week in February 
I expect to proceed to the Canal Zone on official business 
for the Smithsonian Institution, and that in the course of 
this journey I plan to make further scientific studies con¬ 
cerned with birds in the Republic of Panama. The work 
is in continuance of other investigations of the ornithology 
of the Republic that I have carried on for several years 
in the past. 
I will be accompanied by Mr, Watson M. Perrygo, of 
the U. S. National Museum, as assistant, and will expect 
to spend about eight weeks in the field. 
Mr. Perrygo has been with me on several of the pre¬ 
vious trips. My studies will be entirely scientific and as 
indicated are in continuation of work relative to the ornithology 
of Panama that I began in 1944, The results ultimately will 
be publisher where they will be available to scientists in 
Panama and in our own country. The work 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 of my proposed visit. In my earlier 
studies I have had the honor and advantage 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. 
Respectfully yours, 
A. Wetmore, 
Secretary.
