The Plots as shown on the Plans are strips 2l8 feet long of different widths. On the Plan they are 

 shown as running from East to Weit, and are numbered l to 10. Each Plot is sown with a different kind ol 

 seed. Crossing the plots from North to South are 8 manured and unmanurei bands or strips all o\ equal width, 

 viz. 27 feet 3 inches, and 200 feet lo.ng. These strips are marked on the plan A. B.C. up to H. 3.C.E.F. and 

 H. are manured each one differently. The strips A.D. and G. shown by the shaded portions of the plan are not 

 manured. These unmanured strips serve for comparison with the manured strips. The manures that liave 

 been sent with this plan and are marked with the letters corresponding to those on the plan are very carefully 

 spread broadcast on the strips, B.C.E.F. and H. before any of the seeds are sown and harrowed in. The seeds 

 are afterwards drilled in across the strips. Thus the manures are applied in this direction | The seed on each
