moisture-free substance contained in the stem growth and root 
growth and total vegetative growth from 100 seeds of each grade

Fig. 2 — Big Frame grades tested for sprout value in 1913 (table 2). 1, large 
plump; 2, small plump; 3, small shrivelled; 4, dough stage. Relative 
weights of seed 100, 59, 54, 53. Relative sprout values of seed 100, 68, 
50, 58. Slightly enlarged 
moisture in seed tested was determined from a parallel sample. 
In column 10 is given the weight of the inert seed residue remain- 
ing after the seedling extracted all available reserve food. In 
column 11 is given the actual weight of substance contained in 
the seed planted which was not recovered in either the vegetative 
growth or the inert seed remains. The ratio of this loss to the 
original weight of the seed is given in column 12. This loss in
