the maximum amount of acid phosphate was combined with the minimum 

 amount of nitrate of soda. This was an unfavorable season for the 

 growth of timothy and possibly for the most efficient action of the fer- 

 tilizers. The muriate of potash when added alone has produced, for the 

 three years, a net gain of $12.15 per acre as compared with $7.34 for the 

 single application of acid phosphate, and $8.90 for the single application 

 of nitrate of soda. However, when the fertilizing materials are added
