need an application of lime. It has received no lime since 

 ISJtH, when this material was applied at the rate of one ton 

 to the acre. An abundance of lime in the soil is well known 

 to be highly inn)ortant to nearly all U'lrumes. 



The average yields of this year, as affected by the fertil- 

 izers used, are clearly shown in the folhnving table : — 



As the result of all exiieriiiients previous to this year, it is 

 found that the materials furnishing nitrogen have produced 

 crops ranking in the following order : — 



Nitrate of soda, 

 Barnyaril manure, . 

 Sulfate of ammonia. 

 Dried blood, . 

 No nitrogen.

The nitrate of soda, as last year, stands relatively lower 

 than it usually has done. It is believed that the excessive 

 rains of the past two seasons have caused the loss of some of 

 the nitrate of soda ; which may well have washed through 

 the soil and been carried awav in the drainage waters. 



The average yield of all the nitrogen plots, as compared 

 with the average of those receiving no nitrogen, is shown 

 below : —
