 while nitrogen is present only in small amounts, the clovers 

 are likely to predominate. If this is to be the case, how- 

 ever, it is im]iortant that all the other conditions required 

 by clo\'er shall be right. Good drainage, thorough tillage 

 and freedom from free acid are essential. From many parts 

 of the State come reports that clover does not thrive. This 

 in niany cases is doubtless due to the fact that the soil con-

 tion of lime spread on the rough furrow and deeply worked 

 in with a disc harrow will be likely to prove effective. The 

 cut which is here presented shows the effect of liming in a 

 striking manner. Both cylinders were filled with carefully 

 mixed soil, taken from one of the fields of the college farm. 

 Both received an application of the same amounts of nitrate 

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

 addition one cylinder received an application of lime at the 

 rate of 1 ton per acre. After the application of the fertil- 

 izers and the lime, the same kinds and quantities of mixed
