The results considered in the present paper are chiefly from 

 lo experiments, containing 2219 bearing trees and involving 10 dif- 

 ferent soil types. Some of the general features of these experi- 

 ments are given in Table L

It will be noted that the soil types range from heavy clay loams 

 in experiment 218, through silt and plain loams to light sandy and 

 stony loams, in experiments 216 and 219. 



The first three experiments deal with the influence of fertil- 

 izers, and involve 10 treatments and 6 checks in each case. The 

 next four experiments deal Avith cultural methods and involve 12 

 treatments in each case, except the last, which has six. The last 

 four experiments are a combination of portions of the first two 

 types and deal with both fertilizers and cultural methods* As 

 shown in the table, the trees are of 10 varieties, though with one

 experiments are located are as follows : 215, Tyson Brothers, Flora Dale,

 ton; 339, F. T. Mynard, New Albany. 



- In the two sets of figures in this and the following experiments, the 

 first gives the number of trees under fertilizer experiment, the second those 

 under different cultural methods. In Experiment 339, the latter includes 

 only a mulch plot. 



3 Trees set out in connection with these experiments and not yet in 

 bearing, hence excluded from consideration at this time.
