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

 to show heads ; No. 3 was somewhat behind the others. 

 July 30 the barley was cut. The yield of barley from the 

 different plats is given .below : —

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 insolul)le phosphates are ahead, 

 phosphatic slag being first, South Carolina floats second and 

 Mona guano third.
