Dr* Alexander Wetmore, 
c/o Consul-General of the United States, 
Calle Lavalle 341, 
Buenos Aires, Argentina. 
Dear Dr. Wetmore: 
I have your letter of October 18 containing an extreme¬ 
ly interesting account of the results of your activities in the 
region known as the ’’Chaco,” where you have evidently been very 
successful. Your account covering the period from July 1 to 
September 30 has also come to hand* 
I am especially glad to note that beginning about Septem¬ 
ber 6 you were able to make nearly daily observations on the steady 
migration of Golden Plover, Greater and Lesser Yellow-legs, and 
other North American birds. Some of these birds were at that 
time evidently distributed over an enormous area, as Mr. Harper 
has just informed me that he found the Golden Plover in the 
Athabaska Lake region up to about September 30. 
Your trip in the first Ford car which had ever entered 
that part of Paraguay must have been very interesting,to the natives 
as well as to yourselves, and your notes concerning the fauna will 
be extremely valuable. I, too, regret that time did not permit you 
to visit at least one locality in the eastern and higher part of 
Paraguay. I hope that you did not carry any wood ticks across the 
Paraguay River, as if I should find an opportunity to visit that 
region myself, I should like to know of some place where they are 
likely to be absent. 
In regard to your expenses for travel, the $1000 mentioned 
was an allotment of funds made available for your use during the 
first quarter. The sum of $1800 is being held in reserve to cover 
your expenditures during the remaining quarters of the fiscal year, 
and any amount left over from the first quarter is, you know, avail¬ 
able for use in succeeding quarters. The total amount available for 
your use during the fiscal year is therefore $5320.00. This amount 
plus the funds expended previous to July 1 about make up the $6000 
originally authorized for the work. I trust that this amount will 
enable you to carry through your work down there to good advantage.
