manures over the four years. Superphosphate on plot 2 gives 

 a satisfactory result, but basic slag on plot 3 is far more 

 satisfactory, while sulphate of potash added to this latter on 

 plot 4 gives a slight increase. On these two plots again the

quality of the herbage is greatly superior to that on the 

 others. On plot 5 the three successive dressings of complete 

 manure have given great bulk of herbage, but this is coarser 

 in quality. A close examination of the grazed portions of 

 the plots indicates that for grazing purposes the pasture has 

 been improved to the largest extent by basic slag and 

 sulphate of potash without the addition of nitrate of soda.
