" F. N." says: " I clip the following from a Florida paper. Can you tell me if it can be done? I have always understood a plant must be of the same family to insure a successful graft:

" 'A potato growing on a butter bean vine is the latest vegetable curiosity brought to this office. The potato weighs two ounces, and grew two feet from the ground on the bean vine, and eighteen inches from a potato plant. It was found in the garden of Mr. Robert White.' "

To our mind the potato may be a gall formed by some insect.

As for grafts, it is generally believed that plants must be closely related before they will grow together. But a number of very different genera will sometimes graft together. We believe that so eminent a physiologist as Dr. Masters concedes that the potato may be grafted on the tomato, and a great number of genera in the olive family will graft on the privet. We all know that the pear will graft on the quince and on the hawthorn. We do not think a potato would grown on a bean vine; but we should have given the same answer if some one had asked us if a pear would grow on the hawthorn before it was known that it would.
