The following are the results : 



These experiments were carried on for several years with 

 practically the same results. Another set of experiments was 

 carried out with a mixture of superphosphates and bonemeal to see 

 how far the one would assist the other. The same class of soil and 

 barley was used as in the previous experiments, and the following 

 are the results : 



tin* shows that the addition of bone-meal to superphosphate gives 

 little or no advantage to the crop, in fact, when the superphosphate 

 is given in sufficient quantities for the requirements of the crop, the 

 addition of bone-meal is injurious and causes a loss. 



The next set <>f" experiments will show the after-effects of the 

 manures on oats sown in the soil in which wheat lias been grown 

 the previous year. There was only a nitrogenous manure adde< 

 the second year. The following are the results :
