an increased average yield per tree for Fall Pippin, Roxbury, 
Rhode Island Greening and Northern Spy and a decrease for 
the Baldwin. The differences are shown in Table V.

The results at the end of the twelve-year period are quite 
different, having changed the negative result for the Baldwin, 
as shown in Table V, to a positive one; and the positive result 
of the Rhode Island Greening to a negative one. Differences 
in yields for the twelve years are shown in Table VI.

A very interesting fact is brought out in Table VII, namely, 
that both the treated and the untreated plats increased markedly 
in yield from 1893 to 1904 and that the productiveness of the 
orchard was for the treated plats 1.13 times, and the untreated 
plats 1.17 times as great in the second six-year period of the 
experiment as*in the first six-year period, notwithstanding the 
facts that in 1903 in the second period not an apple was borne; 
that the 1896 crop, which came in the first period, was one of 
the most remarkable crops in quantity of fruit ever known in
