Abstract
1. It would seem that in practice no aeration of storage places is necessary after fumigation with CS2 whatever dose may be used, unless they arc airtight. Bins and similar storage places for seeds almost never are airtight and before any of the longer periods reached by these experiments had elapsed the CS2 would have diffused out of the bin. 2. It required very large doses of bisulphide for a considerable period of time to have any marked effect on the germination of the seeds used in this experiment. The injury slowly becomes greater as the time increases and as the dose increases, but is not directly proportional to either. 3. Seeds vary tremendously in their resistance to CS2 injury. 4. Different varieties of the same species are very differently affected, perhaps due to the pigment in the seedcoat. (Note garden beans and cowpeas.) 5. The first injurious effect of CS2 on seeds is a retardation of germination. 6. It seems that liquid CS2 poured on most seeds in fumigation will not injure them sufficiently to be of practical importance.
