260 AGRICULTURAL EXPERIMENT STATION. [Jan. 



June 26 the plants on plats 1, 2, 4 and 5 were beginning

Conclusions. 



From the previous statement of comparative yield we find 

 that the plat receiving dissolved bone-black leads in yield 

 during the first two years, while for the third, fourth and 

 fifth years the plats receiving insoluble phosphates are ahead, 

 phosphatic slag being first, South Carolina floats second and 

 Mona ffuano third.
