THE AGRICULTURAL EXPERIMENTS AT WOBURN. 



tlie wliole is arranged as a fourfold experiment. There are, 

 tlierefore, four simultaneous rotation experiments, each occupying 

 an area of 4 acres, and the cropping is so arranged that each 

 of these areas is simultaneously under a different crop of the 

 rotation, so that when Area I. is roots, Area II. will be under 

 seeds. Area III. wdll be under wheat, and Area lY. will be under 

 barley. This arramrement, besides bein"; most convenient in 

 other respects, possesses the advantage of preventing the con- 

 tinuity of the experiments from being disturbed by the occur- 

 rence of a season unfavourable to any one of the crops under 

 rotation. 



The following diagram shows the ground-plan of this part of 

 the station : —

The actual course of cropping on the four rotation areas is as 

 follows : — 



The roots and seeds are eaten on the ground by sheep, and the 

 barley and wheat are carried off. The loss which the land
