CULTURAL EXPERIMENTS. 



An extensive set of experiments in soil cultivation and management has been 

 inaugurated, but the work is not yet far enough advanced for the publication of 

 results. We indicate below merely the various lines which we are investigating to 

 show the purpose and extent of this work. Next year we hope to have results that will 

 demonstrate their usefulness, though necessarily many years will be required to gather 

 conclusive evidence on some of the problems taken up. 



Briefly, these experiments are as follows : — 



Experiment 1 — Prairie breaking.
