That an experimental field may furnish truly useful indications of 

 the condition of the soil, it must not have received manure for several 

 years ; otherwise, the returns from the different parcels will be so 

 much alike as to be puzzling, and contrasts, such as you see at Vin- 

 cennes, will only be produced after two or three years of cultivation. 

 But this case is not less instructive than the first ; it proves that the 

 soil is piovided with all the terms of the complete fertilizer.
