been applied auiiuallj at the rate of 250 pounds per acre. 

 There are ten plots in the iield, each containing about one- 

 seventh of an acre. Five of these plots receive muriate of 

 potash, and these plots alternate with the same number of 

 plots which are yearly manured with sulfate of potash. 



A large variety of crops has been grown in the different 

 years during which this experiment has continued. The 

 crops of the past year were asparagus, rhubarb, raspberries, 

 blackberries, mixed hay, potatoes and soy beans. On each of 

 plots 13 and 14 four different perennial crops are grown, 

 namely, asparagus, rhubarb, raspberries and blackberries, 

 each crop occupying substantially one-quarter of the area. 

 The hay crof> occupied four plots, the potatoes and soy beans 

 two each. 



No accidental conditions were observed which unfavor- 

 ably influenced any of the crops. It is believed that the 

 differences shown by the table giving the yields are due to 

 the difference in potash salt employed. The rates of yield 

 per acre of the various crops on the different fertilizers are 

 presented in the following table : —
