206 AGRICULTURAL EXPERIMENT STATION. [Jan. 



The crop upon plats I., II., IV. and V. was cut August 

 14, and that on Plat III. August 18. The entire yield was 

 moved into the barn August 20, where it remained stored 

 until September 25, when the product of each plat was 

 weighed and threshed, with the following results : — 



An examination of the above tables shows that the total 

 yield of wheat was highest upon Plat V., and lowest upon 

 Plat III. The larger yield of Plat V. (dissolved bone- 

 black) is in an exceptional degree due to the large produc- 

 tion of straw and chaff, as compared with that of the grain. 

 Plats II. (Mona guano) and IV. (South Carolina phos- 

 phate) yield the largest percentage of grain.
