ments conducted independently by the Bureau of Plant Industry, 
and, finally, to make the record more complete, experiments con- 
ducted independently by various States. 1 
For convenience of discussion the stations from which the data 
published herein have been obtained are arranged, in the list which 
follows, in three groups located, respectively, in the subhumid 
Prairie States, in the semiarid Plains States, and in the arid basins 
and valleys of the Far West. 
Of the data from stations in the subhumid Prairie States, those 
from McPherson, Kans.; Ames, Iowa; Brookings, S. Dak.; and Fargo, 
N. Dak., were obtained cooperatively, and those from Manhattan, 
Kans.; Lincoln, Nebr. ; Ashland, Wis. ; and St. Paul and Crookston, 
Minn., were obtained independently by the State experiment stations. 
In the Great Plains area data from the following stations were 
obtained in cooperation with the State experiment stations: Hays, 
Kans.; Highmore, Eureka, and Newell, S. Dak.; Dickinson and 
Wilhston, N. Dak.; and Moccasin, Mont. At Archer, Wyo., the coop- 
eration is with the Wyoming State Board of Farm Commissioners. 
At Amarillo, Tex., and Akron, Colo., the data were obtained inde- 
pendently by the Bureau of Plant Industry. At Amarillo the Office 
of Cereal Investigations conducts the station in cooperation with the 
Amarillo Chamber of Commerce. At Akron the Office of Dry-Land 
Agriculture conducts the station, and the Office of Cereal Investi- 
gations cooperates in the experiments with cereals. At North Platte, 
Nebr.; Edgeley and Langdon, N. Dak.; Brandon, Manitoba; and 
Indian Head, Saskatchewan, the data were obtained independently 
by the State experiment stations or the Canadian Department of 
Agriculture. 
Of the six stations in the basin and valley areas of the Far West, 
five were conducted cooperatively, namely, Nephi, Utah; Aberdeen, 
Idaho; Burns and Moro, Oreg.; and Modesto, Cal. The sixth, at 
Chico, Cal., is conducted by the Office of Foreign Seed and Plant Intro- 
duction of the Bureau of Plant Industry, with which the Office of 
Cereal Investigations cooperates in the cereal experiments. 
1 The sources of the data from the stations conducted independently by the various States are indicated 
at the proper points in the text. ,The men who have been in charge of the cereal experiments during part 
or all of the years cited,, at stations where experiments have been conducted either independently or cooper-
