1918. [Frank] Alexander Wetmore (1886- ). 
When in the Biological Survey, Dr. Wetmore worked at Lake Burford (Stinking

studying the waterfowl and other birds of that^ region. From here he returned to 
Chama and Albuquerque and then proceeded to Gallup, where he outfitted on 
June 25 for work in the Chuska Mountains. This range was entered from the west 
side and the period until July 4 was occupied in observing and collecting birds on 
the high plateau at the southern end of the mountains. Dr. Wetmore's Lake 
Burford notes were published as Observations on the Habits of Birds at Lake 
Burford, New Mexico (Auk, XXXVII, pp. 221-247; 393-412, 1920). 
Additional Observers. 
In addition to the preceding list of observers whose explorations, collections, 
publications, or special reports give them formal rank among the workers in New 
Mexico, there is a group of men enrolled with the Biological Survey migration and

Among these are Emerson Atkins, A. C. Cooper, F. J. Iiowarth, William M.
