It will be noted that the plots which contained Mineral Fer- 

 tilizer yielded in each instance somewhat less than the plots 

 without fertilizer. The differences, however, are too slight to 

 be attributed tO' the use of the Mineral Fertilizer. The results 

 in this particular experiment, Avith the amount of fertilizer user' 

 show that there was no appreciable beneficial results itom the 

 application of Mineral Fertilizer on this soil and with these 

 two crops. The company's claim that not enough Mineral Fer- 

 tilizer was used may be valid. They, however, were informed 

 of the nature of the experiment and were asked to send the 

 amount of Mineral Fertilizer that they wished to be used on 

 two tenth acre plots. The amount sent was used on two twen- 

 tieth acre plots. Their failure to send any fertilizer for the 

 repetition of the experiment in 1912 would seem to indicate 

 that they were content with the delay of a year in the publica- 

 tion of the results of this trial and did not care to have their 

 fertilizer tested against commercial manures.
