Dear Dr. Wetmore: 
Your letter of November 23 was received a few days ago, 
and I have been expecting every day to be able to advise you that 
your first shipment of specimens had been received. We have a 
bill for transportation, and the shipment is apparently somewhere 
on the way from New York. 
Your letter contains much of interest concerning conditions 
down there, and of birds observed or collected in the course of 
your work. You have a splendid opportunity to secure information 
urgently needed and are apparently taking full advantage of it. 
The migratory movements in two directions at the same time must 
be wonderful things to watch, and I am glad to learn that you had 
located points probably near the center of the wintering ground of 
certain species. Your notes on the appearance of the Everglade 
Kite are especially interesting, and I am glad to know that some, 
but not all, of the birds seen are still at liberty. 
Kay not the small number of individuals noted indicate that 
the wintering grounds may really cover larger areas than generally 
* supposed? I note, that you have reported 13 species and that Peters 
reported another Baird Sandpiper from southern Rio Negro. 
) 
Weather conditions appear to have been unfavorable since the 
first of November for trapping operations, and I trust that you did 
not lose many of your traps, as the stock you carried with you was 
rather limited. Please do not neglect to secure fair representations 
of the smaller mammals wherever possible. 
Since your letter was written you have, of course, revised 
your estimate of funds available in accordance with inj.orm.ation furnished 
in our recent cable. You mention the advisability of visiting the j^aot 
Andean valleys and work in Chile. As already indicated in other letters, 
your movements and the duration of your stay will be left to your own 
judgment based on conditions as you find them and the new estimate you 
have now been able to make of funds still available tor work. It seems 
to me that you should remain until at least most of tne migrant biras
