Mr. Alex Wetraore 
Box 626 
San Juan, Porto Rico. 
Dear Mr. Wetmore; 
Rush of work and absence from town have 
prevented me from acknowledging your various letters. 
I am glad to learn that you are having some success 
in collecting material for an economic report of the 
i s land . 
I am aware that it is very difficult to dry 
specimens in a country where the rainfall is so great 
as in Porto Rico. The majority of the birds have come 
out all right, but a few are a little one-sided on 
account of pressure. If the specimens are well dried, 
a sheet of cotton between each layer should prevent 
the specimens from being mussed. I hope that you may 
be able to secure the Great blue heron which Hr. 
Kenshaw asked you to collect. I trust that you have 
received all supplies which have been forv/arded to 
you. 
Vith best v/ishes, 
Very truly yours, 
L In Charge of Economic I^estigati ons .
