 was to observe the efteets of diflerent nitro'^enous fertilizers furnishing 

 the same amounts of nitrogi'n on the yield of grass ami hay, on the<'om- 

 position of the crop. an<l on the financial results. Tlie 10 eighth-acre 

 |)lats were <tn a medium-heavy loam soil which "was in a low state of 

 fertility." Tlie land had been in grass without fertilizers for several 

 vears. Tlu' plats were scparat«'(l l>y nnmannred strips. The grasscon- 

 sisted chicll.N of timothy, ledtnp. and Kent inky l)lne grass, with a slight
