phase, identified by Ridgway’s “ Color Standards and Color Nomenclature/' 3 may 
be described as follows: 1, 2, 5, mineral green (Pl. XVIII); 3, 4, Veronese green 
(Pl. XVIII); 7, Tiber green (PL XVIII); 8, rivage (PL XVIII); 9, lumiere 
(Pl. XVII); 10, glass green (Pl. XXXI); 6, 11 to 21, deep turtle green (Pl. 
XXXII). 
Figure 4, representing the fruiting phase and yield of ripe grain, shows the best 
solutions to be numbers 3, 10, and 19. The duplicate triangle for this same 
phase, of which results are not here given, showed the best solutions in the same 
outstanding way to be numbers 4, 9, and 20. These are adjoining cultures on the 
triangles, and are hence of nearly the same molecular proportions.

An examination of figures 1, 2, and 3 shows that these solutions are favor¬ 
able to growth during the seedling and vegetative phases, although solution No. 10 
was off-color during the seedling stage. 
The best solution for the seedling phase of growth was considered to be culture 
No. 17, and for the vegetative phase culture No. 20. The green weights of tops 
and weights of roots were also considered in selecting these particular solutions 
as best for the respective phases of growth. 
To determine the best molecular proportion of these salts for the fruiting phase, 
all cultures were carried through the seedling phase with solution 17, and through 
the vegetative phase with solution 20. At the beginning of the fruiting phase,
