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 

 Williston, 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.
