206 AGRICULTURAL EXPERIMENT STATION. [Jan. 



The crop upon plats I., 11. , 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 Se})teml>er 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 11. (Mona guano) and IV. (South Carolina phos- 

 phate) yield the largest percentage of grain.
