Talk of a subscription to help JT’s experiments. Progress of experiment; loss of fungus-resistance in varieties as they age.

Potato crossing experiments. Encloses printed copies of letters from people who have grown his potato seed.

Life history of potato varieties. Changes in fruit, flower, and seed production with increasing age of a variety.
