PLATE 2 
Germination of a weak sample (A and B) and relation of moisture content 
of seed to germination (C). 
A. —No. 375851, standard method. 
B. —No. 375851, “prewetting” method. 
The seeds which do not germinate by the standard method are dead, and 
germination is not improved by the prewetting method. 
C. —No. G-46, germinated in soil in the germinators. 
The seed planted in the box on the right was very dry when received from 
Sacaton, Ariz. (Moisture content, 5.7 per cent.) The seed planted in the box 
on the left was from the same lot, but the moisture content had been raised to 
14.7 per cent by the method described in the text (p. 291).
