Dear Dr. Wetmore: 
In accordance with letter of authorization 
No. 164 Bi, you are instructed to proceed on or about 
November 12 to Athens, Georgia, for the purpose of 
testifying in a dove case to be tried before the 
Federal court there on or about November 15. 
The matter in controversy may cover two points, 
the first the identity of the species known to us as 
the Mourning Dove, and the second the question as to 
whether the Mourning Dove may be considered a migratory 
bird. You are already familiar with the subject and 
have prepared data that may be needed to establish 
these two points.before the Court. 
Upon completion of this matter you should return 
to your official station, Washington, D. C. 
Very truly yours. 
Acting Chief of Bureau.
