Miss Helena Weiss 
Registrar 
A. Wetmore 
Confirming discussion with your office by telephone, it is planned 
that I make official visit to Curasao and adjacent islands in the 
Netherlands Antilles on behalf of the Smithsonian Institution, from about 
January 24 through the no nth of February. 
According to present plan, my work will be concerned especially with 
a detailed study of the birdlife of the island of Bonaire. This study is 
part of iry general investigation and research on the ornithology of tropical 
America. 
In this connection I ask that my official passport be validated to 
cover this travel. At the same time I would appreciate an official letter 
from the Smithsonian Institution as recommendation, whenever needed, to 
local authorities. 
I will be accompanied by Mrs. Wetmore who will assist in the work in 
the field.
