DEY-LAND GRAINS FOR NORTH AND SOUTPI DAKOTA. 



IIIGIIMORE. 



The soil of the lli^hmore substation is of ohicial origin. In texture 

 it (lilfers from tlie Belief ourche soil in that it is not so heavy and is 

 easier to work. It is uniform both in texture and in topography. 

 The results from this station are extremely valuable, both from this 

 fact and for the reason that the experiments extend over a period 

 of several years.' 



DICKINSON. 



The soil of the Dickinson substation is not so heavy as that of 

 either Bellefourche or Highmore. It varies from a sandy to a clay 

 loam. It is productive and is typical of extensive areas in western 

 North Dakota. The field in which variety tests are being con- 

 ducted ajipears to ho. fairly uniform, although check ])lats in some 

 years have made (juite variable yields. 



CLIMATE. 



The climate of Bellefourche, Highmore, and Dickinson is fairly 

 typical of the northern Great Plains. The annual mean temperature'^ 

 at Highmore is 44.5° F. It is 40.3° F. at Dickinson. Records at 

 Bellefourche have not been taken for a sufficient time to determine 

 the mean temperature, but it is probably about the same as at 

 Highmore. 



Table II has been prepared for the purpose of showing the annual 

 and seasonal rainfall for each year during which experiments have 

 been conducted at each of these points. The normal rainfall for the 

 full period for which records are available is also given for the pur- 

 pose of comparison.
