to each other, while all the other trees are free from
any marks of disease."

me with facts that seem conclusive.  Young trees from a diseased
parent do indeed take the yellows; so do those from a
healthy parent; and one as appears to me, is as liable to do so
as the other."  Thinks this point not settled.

14. Is doubtful whether the disease is communicated

15. "If a bud from a diseased tree is inoculated into
