The individual plant data obtained in 1911, and those from the 
new series commenced in 1914, are given in detail in Tables 61 
and 62 and are summarized in Tables 63 and 64. The plants 
grown during these two years were entirely normal, according 
to the fertility of the soil. Figures 19 and 20 show the actual 
ears grown in the 1911 and 1914 fertility experiments. 
Fig. 19. — Ears harvested from the 23 plants in fertility series of 1911 grouped 
according to soil fertility, as follows, reading from left to right — Upper 
row — 1, infertile soil; 2, medium soil; 3, fertile soil. Lower row — 4, in- 
fertile soil plus manure; 5, medium soil plus manure; 6, fertile soil plus 
manure. See Table 61. 
Fig. 20. — Ears harvested from the new fertility series started in 1914. Grouped 
from left to right according to soil fertility: Upper row — 1, infertile soil; 
2, intermediate soil; 3, fertile soil. Lower row — 4, infertile soil, with 
manure; 5, intermediate soil, with manure; 6, fertile soil, with manure 
(3 plants). See Table 62.
