 half of each plot was limed in the spring of 1899 at the rate 

 of 1 ton per acre of quicklime, slaked, and inuncdiately

The seed was sown at the rate of 5 pounds per acre. The 

 variety was Dan vers' Yellow Glolje. Germination was 

 prompt and perfect, but many of the plants upon the nothing 

 plots and upon the unlimed portion of the plots receiving 

 respectively muriate of potash, nitrate of soda, nitrate of 

 soda and muriate of potash, and dissolved bone-black and 

 muriate of potash, soon died ; while such plants as sur^dved 

 upon these plots made but very little growth. The follow-
