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 problems 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.
