The above-described course of tjie general management of 

 the experiment has been followed thus far for five consecu- 

 tive years (1889-93, inclusive). 



For details regarding earlier years (1889-92), see corre- 

 sponding annual reports. 



Summari/ of Four Yearn Observations upon Field A (1889-92). 



Plat 8 has shown, as has been repeatedly pointed out 

 throughout the entire experiment, exceptional conditions, 

 due apparently to injury by insects in the early stage of the 



growth. 



The low yield of Plat 10 in 1892 is evidently due to the 

 use of a lower rate of seed, being the first plat to adjust the 

 seed drill for a definite amount of seed.
