plots may be secured by confining the experiments as closely as possible to one and 
the same part of the field. Up to the present time, December, 1873, nothing has

one square have ever soaked into the soil of adjacent squares, or that the roots of 
any of the crops have made use of fertilizers that were not applied for their especial 
benefit.
