The 5th series of our trials shows that an addition of lime to 
a manure otherwise complete had only a very slight, if any, 
effect. In these trials, however, nitrogen, phosphoric acid 
and potash had been so copiously applied that the lime could 
only act directly, as a nutrient, for which purpose the small 
quantity existing in our soil already sufficed. Under other con¬ 
ditions this manure has frequently proved to be of decidedly 
good effect, as it facilitates the decay of nitrogenous organic
