PUBLICATIONS. 



As rapidly as results of a conclusive nature are secured from the 

 experiments at the farm they are prepared for publication. In this 

 way the facts brought out in the experimental work are promptly 

 made available to the farmers of the region. During the year 1912 

 three ^publications dealing in detail with some of the j^roblems under 

 investigation were prepared. The first of these ^ treats of the pro- 

 duction of grain sorghum, the most important grain crop of the re- 

 gion ; the second ^ reports the results of five years' experimentation 

 with forage crops, and the third ^ deals with the effects produced on 

 crop yields and soil moisture by the practice of subsoiling. Similar 

 papers dealing with other problems will be issued from time to time 

 as the experimental results warrant publication.
