Field B, Comparison of Muriate and High-grade Sul- 

 I fate of Potash. 



On this series of plots we have had under comparison for 

 twenty-four years, as sources of potash, muriate and high-grade 

 sulfate. During this time we have grown practically all the 

 crops common in this latitude and altitude. The crops grown 

 this year and the yields obtained are shown in the following 

 table : —
