186 AGRICULTURAL EXPERIMENT STATION. [Jan. 



The subsequent tabular statement shows the annual appli- 

 cation and special distribution of the manurial substances 

 with reference to each plat since 1889. The fertilizers were 

 in every case applied broadcast as early as circumstances per- 

 mitted. They were well harrowed under before the seed was 

 planted in rows by a seed drill.
