The experiment has not yet reached a point where a final statement 

 can be made as to the relative profits of the practices that are being 

 compared. It does, however, afford some valuable facts concerning 

 tHil'^rSlft to be derived from manuring for timothy, and the eft'ect 

 of this on the corn crop which follows.
