Summary:

Describes self- and cross-fertilisation experiments.

Asks JHG’s advice on setting up an experiment designed to test whether the cause of variation in cultivated plants lies in different substances absorbed from the soil when absorption is not interfered with by other plants in a state of nature. Can JHG suggest how he can get soil free of all the substances which plants naturally absorb?
