INTRODUCTION 
Southeastern Wyoming and adjacent parts of Colorado and Ne- 
braska constitute the district to which the results contained in this 
bulletin are directly applicable. The whole district has a greater alti- 
tude than most of the Great Plains area. The altitude at the Archer 
Field Station is 6,012 feet. The Plains continue to rise as the moun- 
tains to the west are approached until at some places the altitudes 
reach 7,000 feet. The altitude at the eastern boundary of Wyoming 
is about 5,000 feet. The contour varies from almost level or rolling 
to rough and broken by creeks and narrow dry ravines. The land 
along the creeks is usually irrigated and retained in rather large hold- 
ings. The upland is used for pasture and dry farming. 
In 1912 the Wyoming State Farm Board, in cooperation with the 
Offices of Cereal Investigations and Dry-Land Agriculture Investi- 
gations, both of the Bureau of Plant Industry, United States Depart- 
ment of Agriculture, established an experiment station at Archer, 
which is about 8 miles east of Che3 x enne. The State farm board 
has been discontinued, and its functions have been transferred to the 
University of Wyoming. The Office of Cereal Investigations discon- 
tinued its cooperation June 30, 1920. The present cooperating 
bodies are the University of Wyoming and the Office of Dry-Land 
Agriculture Investigations. 
The station farm consists of 685 acres, of which 100 are in the ex- 
perimental field, 68 in the general field, 10 in the farmstead, and the 
remainder in pastures for horses and dairy cattle. Previous to 1923
