Members of tlie Society are earnestly requested to further its objects 

 by causing this experiment to be tried on their own farms, and by 

 sending an accurate account of the weight of the crop to the Secretary, 

 with a statement of the previous cropping, soil, and subsoil. 



These accounts will be compared, and the principal points published. 

 The value of the result will obviously depend on the number of the ex- 

 periments, and on the accurracy with which they are stated.
