Ancon, Canal Zone. 
Dear Don Pedro: 
Perry and I had a busy week in the Canal Zone and a 
speedy journey northward. The plane was delayed so "t/hcit wo did 
not leave Albrook Field until 5:00 a.m., but by making good 
connections in Miami were in Washington at 5:30 that evening. 
The collections arrived the following week and were unpacked 
immediately. Everything has come through in good order and the 
last of the big birds are now thoroughly dried and in good 
condition. 
I want to thank you again for your many kindnesses to 
me and for the assistance that you gave during the course of 
our work in the field. This has been of major help in the 
investigations• 
I turned over the paper on the birds of Panama to the 
library in the Division of Birds in the U. S. National Museum 
where the Curator was very glad to have it since it is an 
addition to his books. 
Under separate cover, by ordinary mail, we are sending 
you an English translation of a manuscript by an old priest who 
traveled in Latin America during the early Spanish period. 
This has a good many sections that I think you will find of 
interest. The book goes to you with our compliments. 
With my kindest regards, I am 
Sincerely yours. 
A. Wetmore, 
S ec re tary.
