For both years, the yields of plot i6 are disproportion- 

 ately low, as shown by comparison with plots 15 and 17. 

 The cause is probably an inequality of the soil. 



In this experiment the green manure makes a very good 

 showing, but the explanation is that plot 23 of this series 

 is located in a low spot in the strip, and undoubtedly 

 receives fertilizer from the adjacent plots. 



Of the remaining series of the Fruit Farm, none have 

 fruited with sufficient uniformity to admit of comparison. 

 The plum series alone is sufficiently developed, but this 

 series has suffered so seriously from the ravages of insects 

 that the fruiting has been very irregular.

Results on the Vegetable Farm. 



The effect of a raw, new soil was more severely felt on 

 the Vegetable Farm than on the Fruit Farm, and the 

 results were somewhat irregular. The crops selected for 

 the various series were as follows : 



(Floi 7.) Sweet Potatoes. No feitiluer.
