II. GERMINATION OF COTTON SEED AND VIABILITY OF 
ANTHRACNOSE AS INFLUENCED BY DESICCATION 
AND BY STORAGE IN INERT GASES 
The foregoing paper has been devoted to a method of treating cotton seed 
with dry heat for the purpose of destroying spores and mycelium of the 
anthracnose fungus. It is the purpose of this paper to describe certain other 
experiments which were conducted in order to study the germinability 
of cotton seeds which have been subjected to various treatments and to 
show the oorrelation between the water content and the resistance of 
cotton seeds to high temperatures and anthracnose control. 
HISTORICAL 
As early as 1834 Edward and Colin 21 tested the effect of heat on the 
vitality of the seeds of wheat, barley, rye, bean and flax. When heated in 
water for 15 minutes, all the seeds were killed by a temperature of 75° C. 
and the upper temperature limit at which the seeds were not injuriously 
affected was found to be 50° C. When the seeds were heated in water
