which is similar in arrangement to fig. 1. In fig. 2 the culture 
numbers have been omitted, and the yields of tops have been 
placed near the intersections designating the several salt pro- 
portions. The area representing high yields is here distin- 
guished by small crosses, the culture giving the very highest 
value being indicated by a large cross; areas of low top yields 
are designated by small circles, the lowest value (obtained with 
three cultures) being indicated by large circles; and areas of 
medium yields are without special designation.

Fic. 2. Relative yields of rice tops. Area of low yields indicated by small circles; area of 
high yields, by small crosses. Highest yield indicated by a large cross ; lowest, by large circles, 
Relative yields of grain are shown in the seventh column of 
Table 3, where the arrangement and method of presentation cor- 
respond to those used for the other yield data; and the grain 
yields have been plotted on the triangular diagram of fig. 3, 
which is similar in arrangement to fig. 2. 
The data showing the relative number of fruiting panicles in 
each culture are presented in the eighth column of Table 3.
