An examination of the above tabular statement of the 

 yield of each plat shows, in every case where no additional 

 nitrogen in any form has been applied in connection with 

 the phosphoric acid and potash used as fertilizer (plats 

 4, 7, 9), a decided falling off in the yield; fully one-third 

 less than where barn-vard manure and nitrate of soda have 

 furnished the nitrogen supply (plats 0, 1, 2, 3). 



Plat 8 shows the same exceptional condition w^iich has 

 been noticed in preceding years, when it seriously suftered 

 from the attack of some parasitic enemy. The low 3'ield of 

 Plat 10 is evidently due to the use of a lower rate of seed, 

 being the first plat to adjust the seed drill for a definite 

 amount of seed. 



Conclusion, — The importance of a liberal additional sup' 

 ply of nitrogen to the soil for a successf id production of farm 

 crops under otherwise corresponding circumstances finds a 

 strong confirmation in our late experiments in that direction^ 

 as may he noticed in the subsequent compiled tabidar state- 

 tnent of the results of three yeari observations.
