INTRODUCTION. 



The cooperative experiments conducted on the Cheyenne Experi- 

 ment Farm, Archer, Wyo., were started in 1912.^ Three years' 

 results of the work are now available. It is reaHzed that three years 

 in a dry-farming district is too short a period to warrant the draw- 

 ing of conclusions. However, the demand for available facts is very 

 strong and these data should be interesting and helpful to those 

 engaged in dry farming in the higher parts of the northern Plains 

 area. Therefore, it seems advisable at this time to present the 

 results thus far obtained. 



Cooperation between the Bureau of Plant Industry and the Wyo- 

 ming Board of Fann Commissioners was effected on July 1, 1912. 

 According to the memorandum of understanding between the two 

 parties — 



The objects of these cooperative investigations shall he {a) to improve the cereals 

 of the northern Plains area by introducing or breeding better varieties than those 

 now grown, with special reference to earliness, drought resistance, winter hardiness, 

 quality, yield, etc.; and (h) to determine the l)est methods of cereal production under 

 dry-land conditions in the area named.
