script notes of F. J. Birtwell and from the data on the species of birds in the Museum 
of the New Mexico Agricultural College at Mesilla. The latter were collected 
largely by Charles M. Barber, who was a student at the college about 1897 and 
collected near Mesilla, and by O. B. Metcalfe, who graduated from the college in 
1903 and collected both at Mesilla and in the Mogollon Mountains. 
1911. Aldo Leopold (1886- ). 
Inspection trips for the Forest Service were made by Leopold from Albuquerque 
in 1911-1913, covering the whole of the Carson National Forest, and 1914-1924, 
covering all the National Forests of Arizona and New Mexico. The Rio Grande 
Valley from Santa Fe to Socorro was constantly traveled, especially during the 
fall hunting season. 
Many of the bird notes made on these trips have been published in the Condor:

1912. Ralph Todd Kellogg (1876- ). 
Before going to New Mexico, Kellogg made a collection of the birds of Ohio, 
his native State, and since the spring of 1912 has been collecting in Grant County 
and the northwest corner of Luna County, mainly within a radius of 20 miles of 
Silver City. 
His published records are: Rare Birds in Arizona and New Mexico (Condor, 
XXIV, pp. 29-30, 1922); Notes from Southwestern New Mexico (Condor, XXIV, 
p. 212, 1922); Notes from Silver City, New Mexico (Condor, XXV, p. 182, 1923) 
1913. Edwin Richard Kalmbach (1884- ). 
Kalmbach, of the Biological Survey, spent some three months (July 28 to 
October 24 1913) in Colfax County, near Koehler Junction, about twenty miles 
southwest ot Raton. As he was working in cooperation with the Bureau of Ento¬ 
mology on the relation of birds to the New Mexico range caterpillar, most of his 
field work was done on the infested open plains, but occasional trips were made 
in the foothills, and side trips were made, on August 5 and 6, to the summit of Eagle 
Tail Mountain, ten miles east of camp, and another, August 27 to 31, to Cimarron, 
28 miles to the southwest. 
1913. Dayton Eugene Merrill (1884- ). 
Prof. Merrill collected for the Biological Survey part of the summer of 1913 
at Mesilla Park and in the Organ Mountains. He also sent a list of all the species
