of course possible that variations in the soil are responsible for 

 the dift'erences in growth. In spite of the fact of these indi- 

 vidual variations, the trees of any particular variety in a given 

 ]ilot exhibit a fair degree of uniformity, and the averages pre- 

 sented below afford a cood indication of the relative effects of 

 the different systems of fertilization followed.

Yields of Fruit. 

 As has been previously indicated, the first fairly full crop of 

 fruit was produced in 1902. Since that date the amount of 

 fruit in different years has varied quite widely. The Baldwins 

 have usually exhibited a strong tendency to produce fruit only 

 in alternate years, the other varieties jjroducing more moder- 

 ate crops, as a rule annually. The follow^ing tables exhibit the 

 nature of the results : —
