Problems of continuing with his crossing experiments; financial help from CD.
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.
Sales of [potato] varieties have reduced amount of money needed [for experiments].
Thanks for CD’s criticism and advice. The difficult question of whether varieties "wear out".
