Coupled with spraying we recommend as a result of our experiments late rather than early digging where rot is feared. That is to say, leave the potatoes in the ground for at least a week or two after the tops are dead. Where this is done there has been little loss from rot in the cellar. While we have shown that thorough spraying with this mix- ture is a sure remedy against both fungi and insects and recom- mend it unqualifiedly for all later potatoes we appreciate the ob- stacles to its use. It means some extra expense for tools and ma- terials and a considerable bother especially until one learns how it is easiest done. Every potato grower will therefore welcome the suggestion that there is promise of at least some relief from the necessity for it. This depends upon securing disease-resisting varieties of potatoes. The variability shown by man and the domestic animals in individual or racial resistance to specific dis- eases is admitted by all. Do
