The results from two years' work on these rotations tend to show : — 



1. That land worked under a rotation including grains and hay gives a greater 

 profit per acre than where wheat alone is grown, and this is emphasized in a. season 

 of early frosts. 



2. Thnt a hoed crop in the rotation increases the cost of operation per acre, but 

 very nmc'i more increases the profit per acre as well as the yield of the succeeding 

 grain crops. 



3. That the diversity of crops affords more suitable food for live stock. When 

 these crops are marketed through the medium of live stock, greater profit per acre- 

 would accrue than is here shown. 



CULTURAL INVESTIGATION WORK. 



A series of soil cultural experiments has been carried on for two years. Marked 

 results as yet have not been obtained. Some treatments that were apparently superior 

 in 1912 have proven inferior in 1913. When, however, these results are related to the 

 precipitation for the corresponding seasons the discrepancies are at least partly 

 explained. The total prcciintation for the year ending March, 1913, was IS-GO inches, 

 ard for the year ending March, 1914, was 15-50 inches. There were 3 inches more 

 rainfall in 1912 than in 1913, and yet the crops sufi:'ered more from drought in 1912 

 than in 1913 because of the difference in the distribution throughout the season. In 

 1912 there was no rain in June until the end of the month, and then there were over 

 7 inches before the end of July. In 1913 the showers were more frequent. 



Following are the results of the various experiments under way: — 



PRAIRIE BREAKING. 



In this experiment five plots are broken each year according to the directions 

 given below. Test No. 1 was commenced in 1911 and No. 2 in 1912. Test No. 1 will 

 be concluded in 1915 and No. 2 in 1916. 



The sequence of the crops is as follows : — 



Fh'st year. — Broken and treated as indicated below. 



Second year. — Wheat. 



Third year. — Wheat. 



Fotirth year. — Summer-fallow. 



Fifth year. — Wheat.
