Obliged for potatoes. Has instructed that they be planted and labelled.

Sends £90 [for experiments on potatoes]. Sorry JT cannot get his varieties well enough known to ensure large sale.

CD’s gardener reports that potatoes were not attacked by disease, but yield was not good. Noble of JT to plan the return of subscriptions if trade continues to improve.

Are plants that arise from vegetative propagation individuals or merely parts of the original parent plant?

Thanks for response to query on what is an individual.

Sends paper on potatoes [see 10440].

Requests permission to publish CD’s previous letter [10440].

Believes publishing CD’s letter will enable JT to suppress the potato disease several years sooner.

Returns CD’s answer to JT’s question "What is an individual?", and repeats his request for permission to publish it.

JT still thinks CD’s opinions on "what is an individual?" should be published.

Seeking financial backing for his research.

Sends some potato plants and tubers.

JT’s crossing experiments on potatoes. Attempts to develop resistance to Peronospora.

Thanks for CD’s assistance and his advice on crossing.

Wants CD to forward to Chancellor of Exchequer a letter which explains the progress he has made in his potato crossing. Wants to print a CD letter to arouse public interest in the work.

Thanks for letter. Prepared to continue experiments if aided. Thinks of distributing new [potato] varieties. Believes seeds should be planted this spring.

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".

Thanks for £100; will pay for planting this year’s varieties.
