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 realized 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 Farm Commissioners was effected on July 1, 1912. 
According to the memorandum of understanding between the two 
parties— 
The objects of these cooperative investigations shall be (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 (6) to determine the best methods of cereal production under 
dry-land conditions in the area named. 
1The writer was superintendent of the Cheyenne Experiment Farm from September 1, 1912, until April 
30, 1915, when he returned to the Nephi substation, in Utah. Mr. Victor H. Florell was appointed scien- 
tific assistant in cereal investigations and superintendent of the experiment farm on April 20, 1915, and 
was in charge during the cropping season of 1915. Credit is hereby given him for the results obtained in 
that year.
