Despite the fact that in this experiment the plants were grown in an 

 entirely different manner and under different conditions from those 

 prevailing in the field, the results were in the aggregate the same. The 

 greatest indication was the need of lime, with either manure or fertilizers. 

 The greatest gain (71%) was with a complete fertilizer in combination 

 with lime. The combinations of nitrate of soda and acid phosphate 

 were very active in producing an increase in growth, but muriate of 

 potash was not effective either with or without lime. Manure pro-
